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:
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.
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.

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.

Ultrabooks feature Intel Core i3, i5 or i7 processors
Many of this year’s hottest new laptops are about one word: Ultrabooks.
The term Ultrabook is actually pure marketing, dreamt up by Intel for a new generation of portable PCs featuring its technology.
Like Centrino but unlike Viiv, it’s starting to stick as a catch-all term for thin and light laptops, or ultraportables as they’re sometimes classified.
The best way to think of an Ultrabook is a MacBook Air that isn’t made by Apple, a netbook that isn’t underpowered or a laptop that’s been on a crash diet. Ultrabooks all feature a Core i3, i5 or i7 processor, plus fast SSD storage and USB 3.0 connectivity.
According to Intel, Ultrabooks also have “ultra-capabilities” – security features, battery power, instant-on and quick standby. They’ll provide a lightweight alternative to tablet devices for people who just can’t work without a full QWERTY keyboard.
Intel has announced a massive $300m (£185m) fund to help develop Ultrabook hardware and software, and it’s confident that Ultrabooks will make up 40% of the market by 2012.
The first models are shipping with current generation Sandy Bridge Core processors, which will be replaced this year by a new generation of Ivy Bridge chips.
Intel set an initial price target of $999/£999 for Ultrabooks, though many have been more expensive – expect serious in-roads on the cheaper £600-£800 market this year.
But what’s the best Ultrabook to buy? Check out the best Ultrabooks we’ve reviewed, as well as some we got hands on with at CES 2012.
1. LG Z330 and Z430 Super Ultrabooks
Rather than a tapered design, the chassis on the 13.3-inch LG Z330 Super Ultrabook is 14.7mm thick from front to back. It runs Windows 7 (for now) and has a bigger brother, the LG Z430, which comes with a 14-inch display. Why is it ‘Super’? Because LG says so.
Asus has done a terrific job with the Zenbook’s design – even if you have to acknowledge that the designer took more than a sneaky glance at Apple’s ultraportable first.The 13-inch Zenbook is fantastic to look at. When closed, the wedge-shaped laptop measures 17mm at its thickest point and a mere 3mm at its thinnest.The same design thinking even stretches to the Intel Core and Windows 7 stickers. We wonder who it was that proposed they were silver and black – Intel? Asus? – but whoever did has made a difference.
Packing an Intel Core i5 processor, the Samsung Series 5 Ultra is small but perfectly formed. Available in 14-inch or 13-inch models, the 13 incher is 17.6mm at its fattest point, narrowing to 14mm.
It comes with a 128GB/256GB SSD or a 500GB hard drive (alongside a small 16GB flash drive) and incorporates an LED SuperBright screen. The only worry? Battery life is low at around three hours in our tests. Not to be confused with the Samsung Series 5 Chromebook. Which is definitely not an Ultrabook.
4. Samsung Series 9
While the original Series 9 was one of the world’s thinnest laptops, the new Samsung 9 Series Ultrabook is even thinner.
The design team has shaved off another 4mm, giving this 13-inch (1600 x 1200) laptop a waistline of only 12.9mm. Inside, a 1.7GHz Core i7 chip does all the hard work, ably assisted by up to 8GB of memory and SSD storage.
Lenovo hasn’t obsessed over aesthetics, and this laptop is no Apple MacBook Air clone. It seems chunky next to the wafer-thin Asus Zenbook, which features a wedge-shaped design that tapers off to a thin, blade-like point.
The Lenovo IdeaPad U300S retains its 16mm thickness across the chassis, giving it the impression of being squat. The body is aluminium, and weighs 1.4kg, the same as the Acer Aspire S3, but much heavier than the Toshiba Portege Z830 and the Toshiba Satellite Z830-10U. If you’re looking for an ultrabook that will turn heads, you will most likely look elsewhere, but can the Lenovo IdeaPad U300S impress with power?
The HP Envy 14 Spectre is a little bigger than your average Ultrabook and a little fatter because of it. Intel specifies a sub- 18mm chassis for 13-inch models, but 14-inchers like this can bulk up to 21mm.
With a Core i5 (or i7) processor and 128GB HDD inside, HP claims a 9 hour battery life for the Spectre. And… that’s really the only appeal.
The Asus Zenbook UX21 is the first 11-inch ultrabook to hit the shelves. Of course, comparisons will be immediately drawn with the Apple MacBook Air, which is one of the best ultra-portable laptops money can buy, and these two 11-inch portables are very closely matched. The Asus Zenbook UX21 matches the Apple MacBook Air in every respect. It’s just as well-built, made out of a single piece of aluminium, just as light and oozes the same head-turning style and class that makes people cast admiring glances while you work in public. It also has the same Intel Core i5 low voltage 1.6GHz processor, and a 128GB solid state hard drive, which keeps the system really responsive and fast.
10. Lenovo IdeaPad U310 and U410
The Lenovo IdeaPad U310 has a distinctly MacBook Pro vibe to it but these Ultrabooks are expected to be at the cheaper end of the scale, around £600 or so. Packing a 13-inch display, the U310 tips the scales at 1.7kg and is squeezed into an aluminium chassis that’s 18mm thick.
A Core i5 chip is expected to provide the processing grunt, with the choice of a 64GB SSD or 500GB hard disk for storage. There’s also a U410, boasting a 14-inch display.
The Toshiba Satellite Z830-10U, priced at £999 in the UK (the US price isn’t yet available).
At its thickest point, the Satellite Z830-10U measures only 16mm across, but Toshiba has still packed in Sandy Bridge power and given us one of the best trackpads we’ve yet seen on an ultrabook. It’s not without niggles, however, and we found parts of the chassis to be inferior to stronger machines such as the Asus Zenbook.
It’s the lightest Ultrabook chassis we’ve yet seen, but also an excellent battery life, this could be the answer for frequent travellers who need a long-lasting machine full of performance for under £1,000.
12. Lenovo IdeaPad Yoga
We’re loving the Lenovo IdeaPad Yoga. This flexible, foldable Ultrabook also converts into a 16.9mm thick tablet with a 13.1-inch (1600×900 pixel) touchscreen.
Running Windows 8 you get the best of all worlds – a QWERTY keyboard for heavy duty working and a tablet experience for after hours net sessions on the sofa. The downside? It probably won’t be cheap.
The 13.3-inch Acer Aspire S3-951 is an appealing prospect for regular travellers. The Intel Core i7 2637M version we tested is priced at £900 in the UK and costs $1300 in the US (where it has the more specific name of Acer Aspire S3-951-6432), which is enticing, considering the impressive specs list.
A less powerful Core i5 model can be bought for £700 in the UK, while in the US there are three cheaper Core i5 machines, two of which cost $900, while one retails at $1199.
14. The Intel Nikiski concept
While not technically an Ultrabook, Intel tells us that a Ultrabook version of the oddball Nikiski is on the cards for later this year.
What makes it stand out is the glass touch pad that turns into a touchscreen layer to enable you to browse a slimline view of key information such as new emails.
15. Acer Aspire S5
Thin (15mm) and light (1.35kg), the new Acer Aspire S5 isn’t much of a design departure from the older Acer Aspire S3.
But it takes advantage of its Ultrabook DNA with a 13.3-inch display, Thunderbolt technology, SSD storage and a fast (but as yet unspecified) Intel CPU. Are we excited? Meh.
16. Novatech nFinity 2367 Plus
The Novatech nFinity 2367 Plus is the first Ultrabook we’ve seen that isn’t from an established, global computer company. That isn’t to say Novatech is small. The British firm has been selling both components and customised PCs for a while, and in keeping with tradition, there’s plenty of choice with its Ultrabook range, with the option of an Intel Core i3, i5 or i7 processor, and varying quantities of storage and memory. The Core i3 Novatech nFinity 2367 Plus model that we were sent is priced at just £625, and comes with 4GB of memory, a 128GB SSD and Windows 7.

A laptop with a short battery life is a nuisance, especially when you’re on the road and nowhere close to a power socket. To make each individual charge of your battery last longer, learn about the 20 Ways To Increase A Laptop’s Battery Life. What is even more annoying than a drained battery however, is a dying battery.
Battery lifetime not only depends on the type of battery and its quality, it also depends on how the laptop computer battery is cared for. In this article I will explain what determines the lifetime of Lithium-Ion laptop batteries, the type of rechargeable battery found in most if not all modern laptops, and what you can do to increase your battery lifetime.
Introduction To Lithium-Ion Batteries (Li-Ion)
Modern laptops are almost exclusively delivered with Li-Ion batteries. They are lighter, offer a higher performance, maintain their charger longer, and are less susceptible to the dreaded memory effect than previous types of rechargeable batteries.
In the US, Li-Ion batteries are classified as non-hazardous for the environment as they do not contain free toxic metals. In the EU however, vendors are required to recycle at least 25% of the batteries they produce. After all, Li-Ion batteries do contain material worth recycling, although the cost of doing so is rather high.
Priming Li-Ion Batteries
The predominant statement you will find is that new Li-Ion batteries do not require priming. Nevertheless, you should fully charge your Li-Ion battery before using it for the first time.
Cycling Li-Ion Batteries
Li-Ion batteries have a lifetime of 300 to 500 full charging cycles or up to 2000 partial cycles. There are reports that cycling a Li-Ion Dell Latitude D620 Battery after long storage periods, i.e. fully discharging and re-charging it for two or three cycles, leads to to capacity gains. Other sources recommend cycling Li-Ion batteries every couple of weeks. Generally, you should not fully discharge your Li-Ion battery.
Caring For Your Li-Ion Battery
While Li-Ion batteries do not have a memory effect and don’t need to be primed or cycled to maintain full capacity, their lifetime can still be shortened dramatically, if not cared for right. Two things can damage Li-Ion batteries: deep discharges and heat. All of the following battery DOs and DON’Ts are derived from these two major factors.
Li-Ion Battery DOs
partially discharge and recharge (no memory effect).
charge at lower voltage.
take out battery when laptop is running with AC adapter connected.
One more thing to keep in mind is that Li-Ion batteries begin aging the moment they are produced and there is little you can do to prevent this. What causes the aging is that the electrolyte slowly breaks down the positive plate, causing the internal resistance to increase to a point where no energy can be delivered. A partial charge and low temperatures slow down this process and hence increase the lifetime of your Toshiba Pa3285u-3bas Battery.
Li-Ion batteries are superior to Nickel-Cadmium or Nickel-Metal Hybrid batteries in that they deliver a higher performance, show a much slower self-discharge, and don’t have a memory effect. However, they do age, withstand only a limited amount of charge and discharge cycles, and are damaged by heat. The best thing you can do to preserve battery lifetime, is to store your notebook battery in a cold place whenever you have reliable AC power available. Alternatively, maintain optimal cooling and airflow to decrease heat buildup. In any case you should perform a full discharge and recharge cycle every few weeks and avoid fully discharing your Li-Ion Acer Aspire 4720 laptop battery in the meantime.

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.

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.

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.
‘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.

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.”

Notebooks tend to lose their charm quickly when you find yourself searching for a power terminal once in every couple of hours to help your dieing laptop battery that is plunging towards the red zone! How do you keep your laptop/notebook battery going for as long as possible? Here are 15 easy tips to do so. Read them now. You’ll thank yourself later.
1. Sleeping Rejuvenates your Body, and your Laptop Battery Too
Use your laptop’s power management features (in Windows XP, under Power Options in the Control Panel; or in Vista, under Mobile PC in the Control Panel) sensibly. The system will run at lower processor speeds when enabling power management features and it will go into “sleep” mode faster when inactive. And if you can spare the extra time it takes for the machine to resume, make sure that you set your laptop to hibernate, not just sleep, when you close the lid.
2.All that Glitters are Not Always Gold
Unless you are still using the laptop that your dad gifted you in the summer of 1999, most modern laptops come with the ability to dim the laptop screen. Some even come with ways to modify the processor and cooling performance. Turn down the brightness of the LCD panel (via the Function-key combo, or in the Control Panel’s Display Settings dialog). Cut them down to the minimum level you can tolerate to squeeze out some extra battery juice. And also consider switching off the backlight that sucks away power from your notebook’s battery like a vacuum cleaner!
3. Cut down Gaming when Running on Battery
Unless you’re running high-order mathematical calculations to solve the university project, chances are great that you don’t need the maximum processing power that your CPU can give. So in Vista, select the “Power saver” power plan (found in the Control Panel, in the Power Options section) to extend battery life when on DC power, and leave the 3D video gaming for when you’re near an AC adapter outlet.
When you aren’t actively using the Wi-Fi, Bluetooth, and IR radios, turn them off (via the hard switch, if your laptop has it, or in the appropriate utility set), so that they don’t trickle you dry trying to connect. Photoshop, iTunes, Google Desktop Search, etc. All these add to the CPU load and cut down battery life drastically. Shut down everything that isn’t crucial when you’re running solely on battery power.
5. Turn Off the Auto-Save Function
Microsoft Word and Excel’s autosave functions are great but because they keep saving at regular intervals, they make your hard drive spin harder than it should. However, if you plan to do this, you may want to turn it back on when the HP prbook 4720s battery runs low. While it saves battery life in the beginning, you will not want to lose your unsaved work when your battery dies, will you?
6. Wisely Schedule Virus Scans
Be sure that your periodic virus scan is set to a time when you’re usually plugged in; running a full-disk virus check keeps the hard drive and CPU fully engaged for the better part of an hour.
7. Lower the Graphics Use
You can do this by changing the screen resolution and shutting off fancy graphic drivers. Graphics cards (video cards) use as much or even more power as hard drives.
8. Go Easy on the Multimedia
A little music is nice while you construct that PowerPoint presentation for your upcoming meeting, but streaming music from your hard drive (or playing a CD) means the disk is always spinning thus sipping away power from your notebook battery.
9. Defrag once in a while
The faster your hard drive does its work – less demand you are going to put on the hard drive and your laptop’s battery. Make your hard drive as efficient as possible by defragging it regularly (but not while it’s on battery of course!) Mac OSX is better built to handle fragmentation so it may not be needed for Apple systems.
10. Cut down External Devices
Use USB-attached devices only when absolutely necessary. They aren’t getting their power from positive ions in the air, you know. USB devices (including your mouse) & WiFi drain down your laptop battery. Remove or shut them down when not in use. It goes without saying that charging other devices (like your iPod) with your laptop when on battery is a surefire way of quickly wiping out the charge on your laptop battery.
11. Get more RAM
This is probably obvious but this will allow you to process more with the memory your laptop has, rather than relying on virtual memory. Virtual memory results in hard drive use, and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.
12. Use Hard Drive rather than CD/DVD
As power consuming as hard drives are, CD and DVD drives are even worse. Even having one disk in the drive can be power consuming. They spin, taking power, even when they’re not actively being used. Wherever possible, try to run on virtual drives using programs like Alcohol 120% rather than optical ones.
13. Operate at Low Temperature
Your laptop operates more efficiently when it’s cooler. Clean out your laptop’s air vents with a cloth or keyboard cleaner.
14. Jack of all, Master of None! Avoid Multitasking
Do one thing at a time when you’re on battery. Rather than working on a spreadsheet, letting your email client run in the background and listening to your latest set of MP3’s, focus your mind to one thing only. If you don’t you’ll only drain out your batteries before anything gets completed!
15. Prevent the Memory Effect
If you’re using a very old laptop, you will want to 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 most laptops have) which do not suffer from the memory effect.
