Windows Phone’s 7.1 Mango update has dominated headlines this week. And rightly so. The updates make the already excellent mobile OS even more appealing, with brilliant advances in terms of Bing search, improved live information delivered to the homescreen and full-on Twitter support.
And that’s before we even get to the belated announcement of Windows Phone Marketplace’s arrival online, offering punters the chance to buy and sync apps on the web as well as on their phones.
But while on paper, and in the flesh, these updates are undoubtedly impressive, Microsoft still has some big work to do to get itself to the top. New partners, in the form of Acer, ZTE and Fujitsu will help globally, if not in he vital US and European markets. But there has to be a question about why this update isn’t being released until autumn.
There is some logic behind the move. Microsoft wants to ensure devs have the chance to bring the new features to existing and future apps, hence they’ve released the SDK now. And trailing operating systems is nothing new: Google did it with Ice Cream Sandwich at I/O earlier this month and Apple will do the same with iOS 5 in the next fortnight.
However, the fear is that Microsoft will take three months to get it ready for devices, only for manufacturers and networks to take their own sweet time testing it and getting it out into the wild. This has already happened with the Big M’s previous Windows Phone update, causing much embarrassment and awkward headlines for the Redmond batteries company.
On top of this, Microsoft will be releasing its Windows Phone update around the same time that Apple updates current iPhones with iOS 5 and rolls out the sequel to its best-selling blower. Just a few weeks later, Ice Cream Sandwich will land on Nexus phones, with new Android hardware doubtless not far behind.
This is tough on Microsoft. Rush the release and risk getting it wrong. Hold it back and they’ll have to go mano-o-mano with the biggest players in the smartphone space. Of course, its Nokia Windows Phones will cause some buzz and generate sales. But will they be anywhere approaching the volume it needs to start pushing up analysts’ smartphone charts?
It’s highly unlikely, especially as Google and Apple look to redouble their efforts in the run up to Christmas. Mango looks the part, just as the first version of Windows Phone 7 did. But there has to be the fear that this will remain, for the time being at least, a niche concern for discerning mobile users.

Looking back in time, there effectively were no consumer tablets in the beginning of 2010. Sure, Microsoft had Tablet PCs for nearly a decade prior, but these were heavy, had relatively short battery life and suffered from a desktop operating system that wasn’t optimized for mobile use. It was Apple’s original iPad, debuting on store shelves in April of 2010, that kicked off the current tablet frenzy. Since then, companies have jumped into this hot market, hoping to score some of the estimated 53.5 million tablet sales that research firm IDC expects this year alone.
Tablet market recap: how did we get here?
It took time for iPad competitors to appear, however, as Research In Motion, HP, Samsung and many others scrambled to create or use new mobile operating system for such devices. At the Consumer Electronics Show this past January, a full eight months after the first iPad arrived, a slew of Google Android tablets were shown off, and I had my first hands-on experiences with RIM’s BlackBerry Playbook. And just last week, HP launched its TouchPad with the webOS system. Of course, while all this tablet activity happened in the first half of 2011, Apple improved the iPad with a successor device that’s even faster than the original, has two cameras and can stream media to HDTVs.
Fast-forward to present day, and now there are a number of tablet choices that simply didn’t exist 14 months ago. It can be overwhelming to pick and choose, because each tablet platform and device has certain pros and cons, even as most have $499 starting prices. I’m in the unique position of having at least one tablet from each platform in hand right now. After using them all in the past few weeks and months, I can’t tell you which tablet is the best for you, mainly because everyone has different needs. But my hands-on usage of these devices can offer insights as to which have standout features and which still face challenges that might not be acceptable to you.
Apple iPad: best all-arounder
The iPad has the advantage of successful “first mover” status, so when many consumers think tablet, they think iPad. And why not? Apple prepared users for the iPad by honing the iOS operating system since 2007. Put another way: If you know how to use an iPhone or iPod touch, then you already know how to use an iPad; there’s no learning curve involved. Aside from the ease of use, the iPad has not only the most apps available to it, but it has all of what I’d call “top-tier” titles. I’d be hard-pressed to think of a killer app from another platform that doesn’t already exist for the iPad.
Apple’s iPad has also provided the widest array of media options for the longest time. iTunes natively has support for major music labels as well as many movie studios and TV content providers. Where it falls short in these areas. it makes up for in the apps: Netflix and Hulu Plus, for example, add content Apple has no license to provide, and these types of apps have been slow to appear on other mobile platforms. Add in simple media streaming to an AppleTV through the AirPlay function, and the iPad makes for a great media solution over competitors.
While there’s much to like. and the iPad is a known commodity with great application support, it’s not for everyone, nor for every situation. Earlier this year, I found I preferred to carry a smaller tablet outside the home and I dumped my iPad for that reason. I later picked up an iPad 2, but my use cases for it are limited to around the house: in bed, on the couch or at the kitchen table. Many consumers tote their iPad all the time,o58itf and while you can take it anywhere, it’s not as easy to use everywhere as a smaller device is. People looking for more portability might consider a 7-inch Samsung Galaxy Tab, BlackBerry Playbook, or HTC Flyer, for example.
Apple’s iOS has also had a few gaps by comparison, perhaps the most notable being the annoying notification system. That’s due to change when iOS 5 arrives in September, bringing a host of other new features that look appealing as well. If you want a large but lightweight tablet that offers a rock-solid experience and the widest array of applications, the iPad should be at the top of the list. Folks that prefer smaller tablets, need Adobe Flash support or want to customize the experience more by tinkering might consider another option.
iPad Pros: Widest selection of apps, media and accessories; solid user experience; overall stability; great performance.
iPad Cons: Lacking features desirable to some: widgets; unobtrusive notifications; variety of customization options.
BlackBerry PlayBook: Flash monster, but where’s the email?
Research In Motion took a bold step by not using their existing BlackBerry operating system for the PlayBook tablet, but it was the right call. BlackBerry OS hasn’t evolved to effectively compete against newer platforms such as iOS and Android, nor has it offered a solid web-browsing experience by comparison. Instead, the 7-inch PlayBook uses the QNX operating system, which brings many superb features, such as excellent multitasking and solid support for Flash. I also like the fast browser, excellent speakers and the gestures used to navigate the tablet’s interface as well as to wake it up from sleep mode.
Third-party applications have been slow to appear for the PlayBook, so once you get through the basics, the software store shelves get a little bare. This is one of the two most limiting factors to the overall sales success of the PlayBook; the other is how it handles email. The PlayBook shipped without a native email client, leaving me to fend for myself with using mail in the browser. That solution works, but requires constant checking and refreshing of the browser; there’s no way for the tablet to notify me when new email arrives. If you have a compatible BlackBerry handset, however, the PlayBook can use the phone’s email client in a bridge mode.
I personally like the 7-inch form factor of a tablet, so the PlayBook fits the bill for me in that regard. It plays Flash and other videos extremely well, and can do so while other applications are running alongside. But those videos will be limited: You won’t yet find Netflix here, for example. And that points to the software situation, which is limited. Enterprises that are BlackBerry-centric will gain more value from the PlayBook than most consumers will, although a limited number of individuals are enjoying their PlayBook purchase. They’re likely making compromises however: Not minding the necessity of pairing a handset with the tablet for email, and living without a vast array of third-party apps and media options by comparison. If you can deal with the same limitations, the BlackBerry is a portable, powerful performer and will improve when RIM releases the native email client.
PlayBook Pros: Great multitasking, Flash support, good security
PlayBook Cons: Few apps, no native email without a BlackBerry handset
HP TouchPad: a promising starter if you can wait for apps
HP’s TouchPad is the newest of the bunch, but its roots harken back to January 2009. It was then that Palm introduced its new webOS platform and the first smartphone, the Palm Pre, to run it. HP bought Palm for $1.2 billion in April 2010 and retooled the operating system not just for smartphones, but for tablets too. The HP TouchPad is very iPad-like in looks (it uses the same 9.7-inch display), packaging and components, but once powered on, it’s easy to see the different user interface approach webOS takes.
To a large degree, the TouchPad faces the same challenge as RIM’s BlackBerry PlayBook; namely, a small number of third-party applications. So, it’s important that HP has the basics right, and in my usage, I’d say it’s mostly successful. Browsing is excellent, and the email experience is arguably second only to that of Google’s. Multitasking is effective and similar to that on the PlayBook. Other fine touches include Synergy, which bundles contact information from a number of sources and a solid Messaging system that integrates Skype video, Google Talk and other platforms into a single app. The webOS notification system may be the best of the bunch, and a unique sliding pane view of email is handy.
HP has built a very solid tablet framework although performance isn’t yet consistent, as applications can lag at times. The company expects to address that and other open issues with a software update, even as it entices developers to build third-party applications for the TouchPad. The webOS platform shows great promise in this area: It may have the best Facebook app on any tablet, for example. I showed it off in a recent video because it has all the standard Facebook functions but also provides a unique magazine-style view of your Facebook news feed. Among all of the new tablet contenders to the iPad’s reign, I think the TouchPad shows the most promise for these reasons. If you’re willing to take a chance and wait for HP and developers to tune the TouchPad and supporting apps, HP’s new tablet is well worth the look.
TouchPad Pros: Possibly the best multitasking and notifications. Basics are well done. Wireless charging.
TouchPad Cons: Very new, so a work in progress. Few apps, media choices.
Google Android tablets: too much choice isn’t always good
There isn’t just one Android tablet, which is both good and bad. By allowing hardware manufacturers to use Android how they see fit, consumers have a wide range of tablet choices with sizes ranging from 7 inches to 10.1 inches. Some Android tablets have 3-D cameras, while others don’t; the same can be said of USB ports, memory card slots, and full keyboard docks. But Android tablets from Motorola, Samsung, LG, Acer, Asus and others share one commonality: They all run on Google’s Honeycomb operating system.
Although Honeycomb was the first tablet platform to follow Apple’s iPad, it actually appears to need the most work yet. No matter which Honeycomb tablet I use, I still see stability issues in the form of software crashes or applications that don’t properly scale up. Stability is less of an issue with Android 3.1, but the third-party application situation hasn’t noticeably improved in a meaningful way. For some reason, software developers aren’t rushing to build or port apps for Google tablets. Simply put: Honeycomb felt rushed to me when I first used it in February, and it hasn’t fully matured yet.
It’s not all bad, however. Users of Gmail, Google Talk video calling and Google Maps will find much to like. These services run well on Android tablets — better than on other platforms, where they’re available. This is part of the reason I switched to a Google Android smartphone last year. Google Music shows promise, as does Google Video for movie rentals and purchases. And although not as flashy as competitors, Android’s multitasking is effective.
But more than any other tablets available today, those running Honeycomb appear most like a poor imitation of Apple’s iPad. It’s as if Google is trying to enable all the same features and functions, but falling short in the user experience: a common complaint of Android in general, although I believe the platform has greatly improved over time. I actually prefer the Gingerbread experience — created for smartphones — on my small Galaxy Tab over any of the Honeycomb tablets I’ve used, and I’ve used a few, ranging from the Motorola Xoom to the budget-friendly Acer Iconia Tag A500, plus some in-between.
Early adopters of Android smartphones have seen this before with the platform, and may be apt to ride out the situation as Android tablets improve. But other consumers may be hard-pressed to deal with Android’s current nuances, issues and lack of software. If you like the ability to hack around in Android and don’t mind software crashes, or if you’re a heavy user of Google services and are willing to wait for platform improvements, you have a number of Android tablets to choose from.
Android Pros: Excellent Google service integration; wide range of hardware options and tablet sizes.
Android Cons: Stability isn’t perfect; app selection is lacking; limited but growing number of media services.
The best tablet is the one that meets your needs
As a secondary device, it’s likely most people don’t even need a tablet. Smartphones, netbooks and notebooks can easily suffice for mobile computing needs. But tablets have their strengths too, offering a personal, more immersive touchscreen experience in many situations. Those situations vary, as do all our individual preferences and requirements for a tablet device. That’s why there’s no “best” tablet I can recommend for everyone. Each has something unique to offer, while all of them are likely to improve over time.
Most are made with similar — if not the same — hardware components too, so that places a greater emphasis on the user experience, software and ecosystem. For many consumers, Apple’s iPad brings the total package like no other tablet, as evidenced by sales figures. But the young tablet market offers something for everyone, and that means you can pick and choose which suits you best; something you couldn’t do before this year.

Top 20 Ways To Extend Your Laptop Battery Life
How to Make Your Laptop as Fast as the Day You Bought It
WASHINGTON — A newly created lithium-ion battery that can heal itself may improve the life span and safety of today’s energy-storage technologies, researchers report.
Rechargeable lithium-ion batteries power cell phones, laptops and other portable electronics. But, like any batteries, they tend to break down over time.
“There are many different types of degradation that happen, and fixing this degradation could help us make longer-lasting laptop batteries,” said Scott White, a materials engineer at the University of Illinois at Urbana-Champaign who reported the details of the battery Feb. 20 at a meeting of the American Association for the Advancement of Science.
One site of damage is the anode, a battery’s negatively charged terminal. As a Dell Latitude D620 Battery charges and discharges, the anode swells and shrinks. Over time, this cycling causes damage, creating cracks that can interfere with the flow of current and, ultimately, kill the Toshiba PA3534U-1BAS Battery .
To counteract this cracking, White embedded tiny microspheres inside the graphite of an anode. As cracks formed in the anode, they tore open the plastic shells, releasing the contents within: a material called indium gallium arsenide. This liquid metal alloy seeped out of the spheres and filled the cracks in the anode, restoring the flow of electricity.
Damage to a battery — or a short circuit between its components — can cause problems other than a shorter life span. Out-of-control electrical currents have been known to create hot spots that grow into a raging fire.
“It’s not a common occurrence, but when it happens, the consequences are severe,” White said. Battery fires have prompted laptop recalls by Dell and Hewlett-Packard, and the U.S. Department of Transportation has proposed stricter rules for cargo planes that transport large quantities of lithium-ion HP laptop batteries.
To safeguard against this type of failure, White developed a second kind of microsphere made of solid polyethylene, an inexpensive and widely available plastic. A small quantity of these spheres embedded in the anode and other battery components can function as a safety cutoff switch. If the temperature inside the Fujitsu lifebook n6210 battery rises above 105° Celsius, the spheres melt into a thin layer of insulating material that shuts off the flow of electricity, preventing a conflagration.
“We’ve tested this in real batteries,” said White, whose research is funded by the U.S. Department of Energy. “It works beautifully.” This safety feature, he said, could be useful for the electric cars emerging on the market.
“Lithium-ion batteries will continue to be the technology used for the next 10 to 15 years in electric cars,” said Kristin Persson of Lawrence Berkeley National Laboratory in California, who is looking for new battery materials that not only have better energy storage but also avoid some of the pitfalls of traditional batteries. “It will take at least that amount of time to develop new materials.”

Batteries Care Instructions
- A new battery comes in a discharged condition and must be charged before use (refer to the devices manual for charging instructions). Upon initial use (or after a prolonged storage period) the battery may require three to four charge/discharge cycles before achieving maximum capacity.
- When charging the battery for the first time the device may indicate that charging is complete after just 10 or 15 minutes. This is a normal phenomenon with rechargeable batteries. Remove the battery from the device, reinsert it and repeat the charging procedure.
- It is important to condition (fully discharge and then fully charge) the battery every two to three weeks. Failure to do so may significantly shorten the battery’s life (this does not apply to Li-Ion batteries, which do not require conditioning). To discharge, simply run the device under the battery’s power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in the user’s manual.
- If the battery will not be in use for a month or longer, it is recommended that it be removed from the device and stored in a cool, dry, clean place.
- It is normal for a battery to become warm to the touch during charging and discharging.
- A charged battery will eventually lose its charge if unused. It may therefore be necessary to recharge the battery after a storage period.
- The milliamp-hour (mAH) rating of the Hi-Capacity laptop battery will often be higher than the one on the original battery. A higher mAH rating is indicative of a longer lasting (higher capacity) battery and will not cause any incompatibilities. A Hi-Capacity battery will, in most cases, outperform the original by 30% to 50%.
- Actual battery run-time depends upon the power demands made by the equipment. In the case of notebook computers, screen brightness, the use of the CPU, the hard drive, and other peripherals results in an additional drain upon the battery, effectively reducing the battery’s run-time. The total run-time of the battery is also heavily dependent upon the design of the equipment. To ensure maximum performance of the battery, optimize the computer’s power management features. Refer to the computer manual for further instructions.Battery Don’ts:
- Do not short-circuit. A short-circuit may cause severe damage to the Asus A32-F3 Laptop Battery.
- Do not drop, hit or otherwise abuse the battery as this may result in the exposure of the cell contents, which are corrosive.
- Do not expose the battery to moisture or rain.
- Keep battery away from fire or other sources of extreme heat. Do not incinerate. Exposure of battery to extreme heat may result in an explosion.www.batteries-company.com is the Australia’s quality distributor & wholesaler of Toshiba laptop batteries, Dell laptop batteries, HP laptop batteries, Olympus camera batteries, Canon camcorder batteries, Makita power tools batteries, Dewalt power tools batteries, Canon battery chargers.

General Battery Information
What Are The Different Types of Rechargeable Battery Chemistries/Technologies?
Batteries in portable consumer devices (laptops and notebooks, camcorders, cellular phones, etc.) are principally made using either Nickel Cadmium (NiCad), Nickel Metal Hydride (NiMH) or Lithium Ion (Li-Ion) technologies. Each type of rechargeable battery technology has its own unique characteristics:
NiCad and NiMH:
The main difference between the two is the fact that NiMH batteries (the newer of the two technologies) offer higher energy densities than NiCads. In other words, pound for pound, NiMH delivers approximately twice the capacity of its NiCad counterpart. What this translates into is increased run-time from the battery with no additional bulk to weigh down your portable device. NiMH also offers another major advantage: NiCad batteries tend to suffer from what is called the “memory effect”. NiMH batteries are less prone to develop this dreaded affliction and thus require less maintenance and care. NiMH batteries are also more environmentally friendly than their NiCad counterparts since they do not contain heavy metals (which present serious landfill problems).
Li-Ion has quickly become the emerging standard for portable power in consumer devices. Li-Ion laptop batteries produce the same energy as NiMH batteries but weigh approximately 35% less. This is crucial in applications such as camcorders or notebook computers where the battery makes up a significant portion of the device’s weight. Another reason Li-Ion batteries have become so popular is that they do not suffer from the memory effect AT ALL. They are also environmentally friendly because they don’t contain toxic materials such as Cadmium or Mercury.
What is the “Memory Effect”?
NiCad batteries, and to a lesser extent NiMH batteries, suffer from what’s called the “memory effect”. What this means is that if a battery is repeatedly only partially discharged before recharging, the battery “forgets” that it has the capacity to further discharge all the way down. To illustrate: If you, on a regular basis, fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity which has remained unused. The battery will remain functional, but only at 50% of its original capacity. The way to avoid the dreaded “memory effect” is to fully cycle (fully charge and then fully discharge) the battery at least once every two to three weeks. Batteries can be discharged by unplugging the device’s AC adapter and letting the device run on the battery until it ceases to function. This will insure your battery remains healthy.
Is it Possible to Upgrade the Device’s Battery to a Newer Chemistry?
NiCad, NiMH and Li-Ion are all fundamentally different from one another and cannot be substituted unless the device has been pre-configured from the factory to accept more than one type of rechargeable battery technology. The difference between them stems from the fact that each type requires a different charging pattern to be properly recharged. Therefore, the portable device’s internal charger must be properly configured to handle a given type of rechargeable battery.
Refer to the owners manual to find out which rechargeable battery types the particular device supports or use our QuickFind search engine to find the device in our database. It will automatically list all of the battery types supported by the machine.
The New Battery Isn’t Charging. What’s the Deal?
New batteries are shipped in a discharged condition and must charged before use. We generally recommend an overnight charge (approximately twelve hours). Refer to the user’s manual for charging instructions. Rechargeable batteries should be cycled – fully charged and then fully discharged – two to four times initially to allow them to reach their full capacity. (Note: it is normal for a battery to become warm to the touch during charging and discharging).
New batteries are hard for the device to charge; they have never been fully charged and are therefore “unformed”. Sometimes the device’s charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge. Don’t worry; it’s perfectly normal.
How Can I Maximize Battery Performance?
There are several steps you can take to insure that you get maximum performance from the battery:
Break In New Batteries
New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge the new battery two to four times to allow it to reach its maximum rated capacity.
Prevent the Memory Effect
Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries which do not suffer from the memory effect.
Keep the Batteries Clean
It’s a good idea to clean dirty battery contacts with a cotton swab and alcohol. This helps maintain a good connection between the battery and the portable device.
Exercise the Battery
Do not leave the battery dormant for long periods of time. We recommend using the battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in procedure described above.
If you don’t plan on using the battery for a month or more, we recommend storing it in a clean, dry, cool place away from heat and metal objects. NiCad, NiMH and Li-Ion batteries will self-discharge during storage; remember to break them in before use. Sealed Lead Acid (SLA) batteries must be kept at full charge during storage. This is usually achieved by using special trickle chargers. If you do not have a trickle charger, do not attempt to store SLA batteries for more than three months.
For Notebook Users
To get maximum performance from the battery, fully optimize the notebooks power management features prior to use. Power management is a trade off: better power conservation in exchange for lesser computer performance. The power management system conserves battery power by setting the processor to run at a slower speed, dimming the screen, spinning down the hard drive when it’s not in use and causing the machine to go into sleep mode when inactive. The notebook users guide will provide information relating to specific power management features.
How Are Batteries Rated? (What Are Volts and Amps?)
- There are two ratings on every battery: volts and amp-hours (AH). The AH rating may also be given as milliamp-hours (mAH), which are one-thousandth of an amp-hour (for example, 1AH is 1000mAH). The voltage of the new battery should always match the voltage of your original unless the batteries are different chemistries (NiMH and Li-Ion batteries have different voltage ratings, even if they’re for the same laptop). Some Hi-Capacity batteries will have higher amp-hour ratings than the original battery found in the device. This is indicative of a longer run-time (higher capacity) and will not cause any incompatibilities.
- New Rating Watt-Hour (Wh):Watt-Hour, or Wh, is a more accurate unit to show the power capacity than Amp-. Hour (Ah) that was used before. The Watt-Hour unit means the wattage that the battery can provide within one hour. 90 Watt-hour (Wh) capacity means the battery can theoretically last 90 hours if the device it powered only needs 1 Watt power, or 1 hour if the device need 90W power. A typical 6-cell internal notebook battery capacity is about 49 Watt-hour. A typical 12-cell internal notebook battery capacity is about 98 Watt-hour.There are many different ways to rate a battery capacity on market. A lithium-ion battery cell capacity is usually measured in Ampere-hour (Ah). Since a battery pack battery uses many battery cells, some cells are connected in parallel, some are connected in serial, using Watt-hour will be more accurate to rate its capacity. If using Ampere-hour to rate its capacity, it should state the Ampere-hour capacity is under which given voltage. For example, 4000 mAh at 11.1V means the battery capacity is 4000 mAh x 11.1V = 44.4 Watt-hour (Wh). 4000 mAh at 14.8V means the battery capacity is 4000mAh x 14.8V = 59.2 Watt-hour (Wh). Although the two batteries have same Ampere-hour, their actual capacity is different.How Long Do Batteries Last (What is the Life Span of the New Battery)?
- The life of a rechargeable battery operating under normal conditions is generally around 500 charge-discharge cycles. This translates into one and a half to three years of battery life for the average user. The amount of charge a battery can hold gradually decreases due to usage and aging.When a battery that originally operated the notebook for two hours is only supplying the user with an hour’s worth of use, it’s time for a new one.Battery Life Expectations :
Battery operating time is affected by:
- Types of power conservation features activated on the computer
- Computer’s type of display and microprocessor
- Number and type of PC Cards and other devices used
- Types of application programs runningShould I Recycle the Old Battery? How?NiCad, NiMH and Li-Ion batteries should be recycled. Be environmentally conscious – do NOT throw these batteries in the trash.
If you don’t know where your local recycling facility is, call the Portable Rechargeable Battery Association at 1-800-822-8837. They will provide you with the address of the recycling center nearest to you.

Smart batteries will generally run 15% longer due to their increased efficiency and also give the computer much more accurate “fuel gauge” capabilities to determine how much battery running time is left before the next recharge is required.

October 15, 2011|By E. Scott Reckard, Los Angeles Times
A Chinese entrepreneur who recently acquired the Balboa Bay Club and Resort in Newport Beach said his next venture will be to build a factory in the region to mass-produce batteries that can power a bus for 1,000 miles on one charge.
Winston Chung said he is developing the new lithium-sulfur Acer Aspire 6930 battery plant as part of a broader plan to export products to China.
He has invested in Balqon Corp. in Harbor City, which builds drive systems for electric-powered buses; and is majority owner of MVP RV Inc. in Riverside, which builds trailers and recreational vehicles.
He believes the region can become a hub for production of electric and battery technology.
“In the future you will see … the market for pure electric vehicles and yachts will emerge from Southern California,” Chung told reporters Friday.
He was in town to accept an award from the United Nations Assn. of New York, a nonprofit support group for the U.N., which made him the inaugural recipient of an annual award honoring entrepreneurs who benefit society.
The Hong Kong resident also said he plans to build a Chinese duplicate of the Balboa Bay Club, a sprawling waterfront facility with a 160-room hotel.

Chung’s Seven-One Capital-Business Inc. agreed in August to buy International Bay Clubs Inc., owner of the Balboa Bay Club and the Newport Beach Country Club, for an undisclosed amount.
The 53-year-old Hong Kong resident said he loves Newport Beach and hopes that “little by little I’ll become a resident of the city.” But he wouldn’t discuss rumors that he already has bought a home in the city. “That’s private,” he said.
A HP 484170-001 laptop battery scientist and inventor, Chung made his fortune in the southern China cities of Shenzhen and Zhuhai, where the communist People’s Republic of China created special economic zones in the 1980s to allow capitalist-style businesses to grow.
He donated $10 million to the engineering school at UC Riverside early this year.

Simple Way to Boost Laptop Battery and Smartphone Battery Storage
Dell rolled out its new lineup of business-focused Windows 8 computers Wednesday, announcing that it would add two portable Latitude devices and a desktop OptiPlex to its offerings once the new Microsoft operating system is released.
While the announcement provided few technical details, Dell did say that the OptiPlex 9010 is a 23-inch all-in-one desktop, and highlighted its incorporation of touchscreen technology and flexible form factor as its chief selling points. The announcement comes less than 10 days after rival HP announced a set of four new all-in-ones designed for use with Windows 8.
Dell’s new enterprise tablet is a 10-inch Latitude designed, the company said, with security and compatibility in mind. The Latitude 10 features a smartcard reader, fingerprint sensor and floor-to-ceiling encryption, along with cross compatibility with existing management consoles and productivity apps.
Finally, the Latitude 6430u ultrabook is a dedicated road warrior’s machine, packing enough battery power for “all-day productivity,” according to Dell, into a package 16% lighter and 33% thinner than the current-generation 14-inch Latitude notebook. The company also claims that the device is designed to meet the U.S. military’s MIL-STD-810G durability standards, which would make it tougher than the average ultra-portable. (It should be noted that Dell has not claimed that the Latitude 6430u has actually been tested to this standard, however.)
All three devices will be made available when Windows 8 is officially launched, said Dell, adding that information on pricing and regional sales would be released “when available.” Microsoft recently confirmed that Windows 8 would see a general release Oct. 25.
Asus always opens its home computer show Computex with a bang and this year it was the Padfone – a 4.3-inch smartphone that docks inside a 10.1-inch tablet dock with dynamic display switching, two batteries, a shared SIM card, a single hard drive, Qualcomm processor, Android‘s next generation operating system (Ice Cream Sandwich) and a Q4, 2011 launch date with a price in the US$800-1,000 area.
While specifics are thin on the ground at the moment, the ASUS smartphone will run on the latest version of Android available at launch and have all the functionality we’ve come to expect from such a device – browsing the internet, checking emails, watching online videos and playing addictive games like Angry Birds. If you find yourself wanting to watch movies or enjoy games on a bigger screen, the smartphone can be docked within the body of the tablet. There’s no need to switch off one to use the other, whatever you were up to at docking time will be continued on the bigger screen and if you receive a call while using the tablet, you could either whip out the phone or connect using a Bluetooth headset.

ASUS says that there will be some sort of shared storage pool in the smartphone part of the device so that users won’t have to concern themselves with synchronizing data between the two. This also suggests that the smartphone will likely provide the processing for the tablet too. The tablet, though, will not be a mere dumb terminal – it will also provide extra connectivity ports and some juice for the smartphone’s battery.
It’s another design masterpiece from ASUS, which consistently demonstrates the ability to think outside the square and the Padfone will enable users to switch between pad and phone for a best-fit user experience – too often I find myself using a smartphone and wanting more screen real estate or a tablet but finding it restrictive in the environment – the Padfone will definitely cure that problem.
It will also be interesting to see if this two-in-one approach encourages Android developers not to charge for separate phone/tablet (“HD”) versions as is very common (and very annoying) on iOS devices.

How to take care of your laptop and laptop battery
Consumer envy continues to be a major selling point when it comes to anything electronics. You know how it goes. No sooner do you buy a latest techie device you thought you couldn’t live without than a better, updated model hits the store shelves. That trend will continue, as there is no shortage of enhancements, features, upgrades, and longer life in the burgeoning consumer electronics area.
This fact is particularly true when it comes to laptops. Everywhere you turn, new laptops, notebooks and netbooks are debuting that are lighter, brighter, and have a slew of new options. Of course, a longer battery life is a selling point as well.
But since most of us cannot buy an upgrade every time one is introduced, we typically need to make do with what we have—for a while, anyway. If you have a laptop that doesn’t have the Acer Aspire 3690 battery life you crave, it doesn’t mean you have to get a new laptop. Rather, consider these basic pointers on improving battery life.
- Lower the brightness. Most people keep their screen at a bright setting for optimal viewing, but the truth is that it is one of the biggest power drains on your laptop battery. The brighter the screen, the shorter the time between charges. With that in mind, simply dimming it to a still-acceptable level will add quality time before you need to power up again.
- Turn off any features you aren’t currently using. A good case in point is the internet. If you don’t need to surf the internet, then a battery-saver would be to make sure you aren’t needlessly creating drain. The same holds true with any programs you have running in the background. It’s easy enough to turn on the programs when you need them and then close them when you don’t. It’s just a matter of creating that consumer discipline so you remember to do that.
- Set your battery setting to “power saver.” This lowers your CPU’s clock speed. While that may not always be what you want, because it means your laptop will be slower, if you alter it to a satisfactory level you may not notice the difference while saving on HP 484784-001 notebook battery life.
Also consider keeping a backup laptop battery on hand so that when your current battery no longer does the job you require then make it your emergency backup and get yourself a high performing, new battery to keep you powered up.

Tips for keeping your laptop working better
How to take care of your laptop and laptop battery
Released just last week in Developers Preview mode, Windows 8 already contains more than 300 new features. At its Build developers conference, Microsoft pointed to plans to keep adding more new capabilities until Windows 8 evolves into a shipping product. Which of the existing features are most important to get to know about right now?
While no list like this can even approach ‘all inclusiveness’, our list of ten key features in Windows 8 ranges across new jargon such as “charms” and “snap muti-tasking,” to first-time operatibility on ARM-based tablets, to major improvements around support for USB 3.0, touch keyboards, file copying, and more. Here, in no particular order of importance, is the list of ten:
1. Support for both x86 PCs and ARM tablets
Windows 8 is the first edition of Windows to operate on both ARM-based tablets and traditional x86 PCs based on ARM processors from Intel and AMD.
“Support for ARM-based chipsets, touch, and sensors makes Windows 8 work beautifully on your choice of a full spectrum of devices, such as 10-inch slates with all-day battery life, ultra-lightweight laptops, and powerful all-in-ones with 27-inch high-definition screens,” Microsoft contends, in a Windows 8 Guide distributed with Windows Developer Preview
In addition, the ARM edition of Windows 8 includes a new mode dubbed “always on, always connected,” designed to let tablets act like smartphones. Tablets can remain in standby mode without disconnecting from the Internet, and then wake up instantly.
Windows 8 is designed to work seamlessly across both PCs and ARM tablets. Yet until developers get a real start on apps for Microsoft’s still empty Windows Store, it’s tough to tell whether that will be universally true.
2. Touch-centric, Tiles-based User Interface (UI)
Although Windows 8 might look and feel like an entirely new “user experiemce,”, Microsoft is actually layering a new animation-enabled user interface (UI) on top of an only somewhat upgraded Windows 7.
The Windows 8 Start Menu is customizable through a mosaic of tiles, which differ from traditional desktop icons by letting you view live information from Windows 8 Metro style apps without actually accessing the apps.
In demoing the tile-based UI at last week’s Build conference , Microsoft showed how the tile for a Windows 8 weather app is able to display the current temperature in a city – along with projected temperatures for the next two days – without requiring you to open up the app. A tile for Windows Live Mail will show you your latest message, while a tile for a social networking app will show you notifications.
“The [Metro] apps are full-screen. They’re beautiful.They’re designed for touch, but of course, they work great with a mouse and keyboard as well if that’s what you have. We wanted to make it really fast and fluid for you to switch between them,” according to Jensen Harris, lead program manager on the Microsoft Office User Experience..
Windows 8 users are also able to access Windows 7 apps. “Everything that runs on Windows 7 will run on Windows 8,” maintained Steven Sinofsky, president of Microsoft’s Windows and indows Live division, during a keynote at the Build conference. However, in order to access Windows 7 apps, you need to switch to a different built-in UI.
In large part, ‘charms’ is a new implementation of the traditional Windows start bar. Charms can also be used to quickly configure settings for individual apps. On an ordinary non-touch PC, charms are accessed by dragging the mouse to the bottom-left corner of the screen, to the same spot as the old Windows start button. On a tablet, you swipe from the right side of the screen to bring up charms.
Microsoft recently applied for a trademark on charms. The charms sidebar offers five sets of options, supporting both app-specific settings and system settings such as volume and brightness. The options include Start, Search, Share, Devices, and Settings. The Start option returns the user to the home screen. The Devices option presents a list of connected devices. Under the Share option, users can see social network sharing apps.

4. Snap Multi-tasking
‘Snap multitasking” is designed to make it easy to run two apps in Windows 8 side-by-side, to resize them, and to switch between them. On the right-hand side of the screen, you can snap an app into place.
You can make an app smaller or larger by dragging the bar for the app. To switch between apps in Windows 8, you swipe from the left-hand part of the screen.
However, Windows 8 does not allow you to view all of your running apps on a single screen.
5. Windows 8 Control Panel
Beyond revamping the Windows task manager, Microsoft has also redesigned the control panel for Windows 8. New options include Personalize, Users, Wireless, Notifications, General, Privacy, Search, and Share.
As Metro style apps become available, you’ll be able to use the Personalize menu to customize the Start menu with tiles for calendar, music, e-mail, Netflix, and much more.
In a demo at Build, Julie Larson-Green, Microsoft’s corporate VP of program management for Windows, showed how you’ll be able to position these Metro apps on the screen, and also to combine them into groups such as friends and games.
6. Web Navigation by Touch
The Internet Explorer (IE) 10 browser built into Windows 8 is designed to offer faster browsing through greater hardware acceleration, along with rapid gesture-based zoom, pan, and Web site navigation.
As in other areas of Windows 8, you can quickly access Windows 8 charms, as well as the two keyboards described below.
7. Two Touch Keyboards
Windows 8 also contains two soft keyboards: an “enhanced” traditional keyboard, plus a new thumbs keyboard for non-touch typists.
In efforts by Microsoft to make typing on a virtual keyboard faster and more accurate, the revised edition of the conventional keyboard suggests words on the screen as you type. You can then tap to selected a suggested word. Microsoft also provides a spellcheck-like feature designed to automatically correct mistyped words – although like any other spellchecker, this feature carries the potential to cause its own errors.
The keyboards are also aimed at automatically adjusting to whaever human language you choose for Windows. These language settings will automatically apply to the entire computer, instead of only to specific apps
8. ‘Enhanced Copy Experience’
Windows 8 also introduces the ability to perform all current copy operations into a single dialog box, instead of requiring you to perform file copying in separate dialog boxes for each app.
The new dialog box for file copying lets you pause, resume, and stop each sopy operation currently under way. It will also warn you if you’re beginning to copy one version of a file on top of another.
Microsoft has also added a realtime throughput graph. “Now each copy job shows the speed of data transfer, the transfer rate trend, and how much data is left to transfer. While this is not designed for benchmarking, in many cases it can provide a quick and easy way to assess what is going on for a particular [copy] job,” noted Alex Simons, director of program management with the Windows 8 management team.
9. Native USB 3.0 Support
New USB 3.0 ports operate at speeds up to ten times faster than )SB 2.0. To better support these speeds, Microsoft is outfitting Windows 8 with native USB 3.0 drivers.
Meanwhile, though, USB 3.0 will purportedly continue to work under Windows 7, through the use of third-party drivers.
“By 2015, all new PCs are expected to offer USB 3.0 ports, and over 2 billion new ‘SuperSpeed’ USB devices will be sold in that year alone,” said Dennis Flanagan, director of program management for the Windows 8 Devices and Networking Group, in a blog post. “There are also billions of older USB devices that Windows must remain compatible with.”
10. Better Support for Multiple Monitors
Windows 8 also brings increased support for multiple monitors, The Developers Preview of the new OS includes first-time capabilities for extending the taskbar across two PCs, without any need for third-party apps. You can also stretch wallpaper across two monitors, or display the Start screen on one PC and the desktop on the other, for instance.
It’s also easy to switch between multiple monitors. The primary monitor has a start button, and the secondary monitor has a switcher button. Clicking or tapping on the switcher button will swap it out for the start button, allowing you to turn the secondary monitor into the primary one.

How to take care of your laptop and laptop battery
Scientists at Cambridge have developed a simple, accurate way of “seeing” chemistry in action inside a lithium-ion battery.
By helping them understand how these batteries behave under different conditions the new method — which involves Nuclear Magnetic Resonance (NMR) spectroscopy — could help researchers solve the fire safety problems that have dogged the development of these laptop batteries.
Lithium-ion battery technology has enabled the development of many electronic devices we now take for granted, such as laptop computers and mobile phones.
Lithium HP COMPAQ 395794-001 Battery technology will also be crucial for the development of the next generation of electric cars such as the Nissan Leaf, due to be built in the UK from 2013.
But lithium batteries have one serious disadvantage: over several charge and discharge cycles, particularly if the batteries are charged quickly, minute fibres of lithium, known as dendrites, can form on the carbon anodes. These lithium fibres can cause short circuits, causing the LG LB52113B Battery to rapidly overheat and catch fire.
Writing in the journal Nature Materials, Professor Clare of the University of Cambridge says: “These dead lithium fibres have been a significant impediment to the commercialisation of new generations of higher capacity batteries that use lithium metal as the anode instead of the carbons used today.”
Scientists have use theoretical models and optical and scanning electron microscopes to study dendrite formation, but finding a way of quantifying the amount of dendrites formed has proved elusive until now.
The paper describes using a new method based on NMR spectroscopy to see chemistry in action within a tiny, 1cm long, Acer Aspire 5920 Battery enclosed in the same kind of aluminium bags used to keep coffee fresh.
According to Professor Grey: “Fire safety is a major problem that must be solved before we can get to the next generation of lithium-ion HP COMPAQ 8510P Battery and before we can safely use these batteries in a wider range of transportation applications. Now that we can monitor dendrite formation inside intact batteries, we can identify when they are formed and under what conditions.
Our new method should allow researchers to identify which conditions lead to dendrite formation and to rapidly screen potential fixes to prevent the problem.”
