Most of us do work while on the move, and in such situations an ultra light laptop with good battery output is what we require the most. The Acer Aspire Timeline series 1830T-3721 is one the ultra portable laptops with a whooping 6 hour Acer as07b31 battery life and under thousand dollar range, is one the hot favorites for those who normally work out of office.
Build – Design – Hardware
The laptop design is on the lines of Aspire One Netbook and weighs approximately 3 pounds. Its easy to carry this laptop and it is powered by Intel Core i5 for solid performance. The body is fingerprint proof, and sturdy enough to withstand the jerks and bumps. This small machine does get heated up, but it’s manageable. The 11.6’ screen is compared to a netbook screen, but its far better than any netbook available today.
Keyboard – Mouse – Webcam
The keys are textured, the keyboard is spacious and like all Acer laptops this machine too has flat keys. The right and left Shift keys are big in size, useful to manage all those shortcuts. The touchpad is almost invisible, but quite sensitive and responds well to your touch. The right and left click buttons are equally comfortable. The inbuilt web camera serves its purpose and its good for those frequent Skype video calls.
Connectivity – Ports – Battery
3 USb ports, HDMI Output, Multi Media card reader, Ethernet Slot, VGA Output, Mic and headphone jacks support this laptop the most. This Wi-Fi enabled laptop has an excellent battery life of 6 hours and for that very reason its called the “Small Wonder”

Acer debuted their first Ultrabook the Aspire S3 at IFA this week. While it hasn’t landed on US shores yet, that didn’t stop us from giving a little love to this slim vixen.
The Aspire S3 is encased in a thin, light metal design that weighs less than 3 lbs, has a 13.3 ultra-thin HD LED, is outfitted with a full-size chiclet keyboard, and a high-density battery that delivers up to 7 hours of battery life. Some highlights are Acer’s Green Instant On technology which provides instant-resume functionality that aims to ensures longer battery life. If the Acer Aspire S3 has been in sleep mode for less than 30 minutes, it will resume in under 2 seconds. It will resume from deep sleep in 6 seconds. The unit enters deep sleep state after 30 minutes of no activity and is part of the Acer aspire 5620 battery saving measures that allow up to 50 days of battery life. That’s longer battery life than practically any other mobility device on the market right now!
The Aspire S3 also offers several Intel processors to choose from, the 2nd gen Intel Core i3/i5/i7 processors and a choice of 240 GB SSD or 320/500 GB HDD with embedded SSD.

If you were lucky enough to get an HP TouchPad this time last year during their “fire sale” for $99 (16GB) or the $149 (32GB) your Android luck hasn’t run out yet. Remember, Android first came to the HP TouchPad via CM7, Gingerbread. A few months later, Android 4.0 came to the HP TouchPad, bringing a true tablet UI to the 10″ popular slate. The CyanogenMod development community continues to grace the HP TouchPad, this time with Android 4.1.1 Jelly Bean showing up via an unofficial CM10 preview release.
This preview released is exactly what it says it is. A preview of things to come. WiFi seems to be working great and many apps are working as you can see from the demo video below. As of right now, audio does not work and you cannot play videos via YouTube or from the Gallery. However, you can play videos via the MX Player app (without audio). Besides those minor hiccups, Jelly Bean is buttery smooth on the TouchPad as advertised and Google Now even works!
If you’re itching to pull the trigger to give this preview release of Jelly Bean, CM10 a try, here’s how you can get started:
The following is assumed you are familiar with installing CM7 or CM9 on your HP TouchPad. Please proceed at your own risk.
PLEASE DO A NANDROID BACKUP BEFORE PROCEEDING.
Batterylicious is the USA leading distributor & wholesaler of Acer laptop batteries, Toshiba laptop batteries, Dell laptop batteries, HP laptop batteries, Fujitsu laptop batteries, laptop chargers and battery charger.

Your HP TouchPad will begin installing the CM10 preview release.
How time flies! In the year 2000, I was just finishing high school, listening to Bush, and becoming acquainted with Windows 2000. Back then, I knew very little about Apple, and I’d certainly not heard of the Bondi Bubble iMac (the first iMac was released in 1998). In 2010, well…how things have changed for me!
And, as illustrated by Brett Jordan in the graphic above, things have also changed at Apple.
It’s incredible to think that the iPhone has taken center stage at Apple over the last three years. As noted by some of our commentators, there has been a real lack of Mac-centric news recently. Sure, there was the update to the iMac a few months ago, but it’s glaringly obvious that the Mac has taken a back seat to the iPhone — certainly in the limelight department. In fact, I’m reveling in the fact that I’m writing about the iPhone and the iMac at the same time!
Today, the Mac is the center of our digital hub, but it’s no longer the center of our digital world. When we leave the house / office / room where the Mac lives, it’s the iPhone ( iPad / iPod touch) that is constantly in our hands, and Apple knows it!
Of course, we have to come back to our Macs eventually (in my case, repeatedly, everyday) because the iPhone can’t do everything that we want it to, or even some of the things that we want done well, yet. But just looking at this picture shows how far things have come, and how the direction taken by personal computing is becoming even more personal.
The only feature of the iPhone 4 that doesn’t beat the iMac of yesteryear is screen real estate. The processor and RAM are double the capacity of the iMac, the iPhone’s storage is 2 gigabytes larger, and it’s flash-based memory. And of course, it’s tiny in comparison. As noted by Obama Pacman, it’s Moore’s law in effect.
But when will it end? In 10 years time, will we have an iPhone that’s five times smaller than the current one, but more powerful than the personal computers of today? Who knows? That might be a weird phone, but anything could happen. For now, I’m still stuck with my iPhone 3G, and I think it might still have some Bush on it. In the meantime, I’m just looking forward to getting the iPhone 4!
Looking to power up your iPhone with the best free and cheap apps out there? Our first edition of the Lifehacker Pack for iPhone rounds up our favorite must-have iPhone applications.
Whether you just bought a new iPhone or you’re simply looking for some of the best basic apps for your device, the list below should be plenty to get you started. The majority of the apps are free unless otherwise noted, and where they’re not free, we aimed for cheap. And when a default application is incredibly useful and blows all its competition out of the water—we included it, too. It’s a big list, so here’s an index if you want to quickly jump to a section:
Where most mobile companion apps tend to offer a lot less than their desktop counterparts, ubiquitous capture tool Evernote takes full advantage of the iPhone to make the mobile app worthy of standing on its own. In addition to capturing regular text, you can grab voice notes and photos as well. Since Evernote performs OCR (optical character recognition) on all your images, any text in the pictures you add to Evernote will be searchable. For example, you could take a snapshot of a menu in a restaurant and later search it just like it was a text document.
Simplenote is a key component in the holy grail of ubiquitous text capture
, and rightfully so. Simplenote allows for speedy note entry on your iPhone, plus it syncs with the likewise free
Simplenote service so your notes are always available wherever you want them.
If you haven’t used TripIt to manage your travel itineraries, you’ve been missing out. We’ve already discussed its merits, but the free iPhone app makes it even easier to manage your trip. It’s a natural extensions of the service, since if you’re traveling it’s more than likely that you’re not at your computer.
Instapaper / ReadItLater:
Instapaper and ReadItLater both serve the purpose of saving web content for later reading, and both offer free and paid versions, but they’re still notably different. Instapaper offers you a straightforward and simple way of reading saved content. ReadItLater is a little more feature-rich. Both are great options and you can try them for free to see which you prefer.
Apple’s voice recognition handles a few tasks but misses some key features that Dragon Dictation helps to fill in. If typing is not an option, or you’re just feeling lazy, Dragon Dictation will type it up for you. You can send a text message or an email directly from the app, and it also integrates with Facebook and Twitter. Although not perfect, Dragon Dictation is surprisingly accurate and will let you correct any mistakes it makes.
Mint: If you’re not using Mint to keep track of you finances, you should be. It’ll keep track of all your accounts and provide you with useful statistics and budgeting information to help you manage your money better. If you’re looking for something a little more hands-on, however, Jumsoft Money is a great free app as well—you just input everything yourself.
If you’ve found Mobile Safari to be a bit lacking, you’re not alone. Atomic Browser can help, providing true tabbed browsing, private browsing mode, user-agent spoofing (handy for watching Netflix on your iPhone
), and a ton of features you’ve come to expect as part of your web-browsing experience.
Imagine being able to use your iPhone to make phone calls! (Har har.) Now that Skype works over 3G and can take advantage of iOS 4’s multitasking capabilities, it’s actually a viable alternative to using your mobile minutes. Even if you don’t want to go so far as to replace your regular phone, it’s still a great tool for making international calls on the cheap and chatting with your Skype contacts on the go.
If you don’t like paying a ridiculous amount of money for small amounts of data, Textfree Unlimited lets you send and receive text messages at no costs. You can even set up a phone number specifically for the app. While Textfree used to only provide free text messages, now the app is free as well. The trade-off is that you get ads, but you have the option to pay to remove them.
Another great minute-saver is LucyPhone (check out our quick review), the app that waits on hold so you don’t have to. If you’re calling a popular business, LucyPhone’s directory may even save you the step of going through the phone tree to get to the right department. While you might confuse the customer service representative on the other end, LucyPhone takes all the pain of waiting on hold—including the loss of your mobile minutes.
With a couple of $10 multi-service IM clients available, Meebo stands out especially because it’s free. Being free doesn’t make it bad, however. It’s an attractive app with the ability to integrate tons of IM services, making it our IM app of choice.
You could drown in Twitter apps on the iPhone, but the official option is free and one of the best. In addition to tweeting and direct-messaging, you can also share photos and videos. Thanks to the iPhone’s GPS, Twitter is location-aware and can provide you with nearby tweets so you can figure out what people are talking about in your area in real time.
The official Facebook app on the iPhone is great for general updates and messages, but it becomes especially useful when all your contacts flood in. If your address book is missing a number, just find your friend in the Facebook app and click the call button. You can also keep track of events, check your news feed, and edit your profile.
Maps (Default App)
While Android’s version of Google Maps blows it out of the water, the built-in Maps application on the iPhone is still pretty great. Drivers can check real-time traffic and get simple directions to just about anywhere. Even if you don’t drive, walking and public transportation directions are available. With street view integration and a few other neat features, Maps is easily one of the most useful apps on the iPhone.
While the iPhone has a few free turn-by-turn navigation apps (and none of them are even encroaching on the territory of perfect), MapQuest4Mobile feels more like the real deal than any of the others. In my personal experience I found it gave directions too late in quite a few cases, but it’s hard to argue with free. If you want a commanding, computerized female voice barking directions at you (occasionally after you’ve missed your exit), and you don’t want to pay a lot for the privilege, you’ve found your match.
Although not free (weighing in on the more expensive side at $2.99), GasBuddy is the sort of app that can pay for itself after one use. If you’re always on the lookout for cheap gas, GasBuddy will give you options by proximity and price. You can filter by fuel grade, and it can even help you find a diesel gas station.
If you’ve ever wanted to see a movie on a whim, Movies Now scratches that itch. While it handles regular movie showtimes, too, it’s main function uses your location and the current time to find upcoming showtimes near you. If you find a movie you like, you can buy tickets through movietickets.com directly from the app. The catch: It’s $2. While there are certainly free options in the movie showtimes arena (like the IMDb app below), Movies Now has a great location-based twist.
You have quite a few fitness apps to choose from on the iPhone. One of those happens to be RunKeeper, and lucky us, it has a great free version. RunKeeper uses your iPhone’s GPS to track your run and provide you with statistics, giving you the statistical benefits of a treadmill when you’re outside the gym. It integrates with your music library and lets you share your activities. While the built-in Nike+ app is also pretty nice, RunKeeper doesn’t require the purchase of any additional hardware and lets you choose your brand of shoes.
Find My iPhone:
Even if you’re not a MobileMe subscriber, you’ve probably heard a bit about Find My iPhone in the news. It’s already tracked down a few iPhone thieves, but is probably more commonly used when you’ve just misplaced your phone. While you have to shell out $99 a year for a MobileMe account to get any use out of the app, it’s a must if you’re already a MobileMe subscriber.
Would it truly be a Lifehacker Pack without file-syncing app extraordinaire Dropbox? While the iPhone version of Dropbox isn’t quite as useful as Dropbox on your computer, it makes for a nice companion. If you’re using Dropbox for all sorts of clever things
, it’s always nice having access to your sync’d files from your phone. While the Dropbox app can download anything the iPhone (or a third-party app) can display, you can also save key files on your phone as well.
If you like frequent push notifications, you’ll probably like Boxcar. Boxcar integrates with Twitter, Facebook, email, RSS, and Growl to grab updates of nearly anything you want and push them to your phone. If you want to be alerted the moment something changes, Boxcar will get the job done.
PasteFire / MyPhoneDesktop:
PasteFire and MyPhoneDesktop do the same thing—they aim to make getting text from your desktop to your iPhone a bit easier. Both use push and both integrate with your machine to send content. The biggest difference is price: PasteFire is free and MyPhoneDesktop costs a whopping $5. So why mention MyPhoneDesktop? I think it works better. Still, no penalty for trying PasteFire. MyPhoneDesktop is really only worth a look if the free option doesn’t cut it for you.
If you want to use your iPhone as a wireless trackpad for your Mac or Windows PC, that’s precisely what Touch Mouse can help you accomplish. It also includes keyboard functionality so you can make use of your iPhone’s keyboard to input text. While this is not terribly practical or speedy for use with just any machine, if you have a computer hooked up to your television it’s a convenient way to navigate without the clutter of a keyboard and mouse on your couch.
Pandora’s always been a favorite on the iPhone, but with multitasking support in iOS 4 it becomes so much more useful. Now that you can listen to your personalized Pandora radio stations in the background, you’ll be hard-pressed to find a better, free way to discover new music.
Although it’s nearing a year without an update, Apple’s Remote app is still pretty incredible. If you want to control your iTunes library remotely, or turn your iPhone into a multi-room wireless remote
(in the event your have an Airport Express or AppleTV), there’s really no better option—especially for free.
Air Video / StreamToMe:
Air Video and StreamToMe are both apps that help you stream video from your computer to your iPhone, no matter where you are. They’re especially compelling when you want to watch something at, say, the gym and you didn’t have time to transcode and sync it to your device first. Whether you’re connected to Wi-Fi or 3G, you can stream video directly to your phone from anywhere you are (the quality of your connection permitting, of course). Both apps have some subtle differences, such as StreamToMe’s ability to stream more than just video and Air Video’s option to pre-encode content for easier streaming, and either are worth the price of admission: $2.99.
iBooks / Kindle / Stanza:
It’s hard to consider any of the iPhone ebook readers the best choice because they’re pretty similar. They all let you read on your phone, they all let you purchase books, and they’re all free to download. While I’m partial to the Kindle app, it’s mainly because I started with ebooks via the Kindle. Pick the ebook app that works the best for you—or don’t, since they’re all free downloads.
Food and Entertainment
Yelp has yet to fail me when I’m on a search for some good, nearby eats. It also comes with some semi-secret, fully-nifty augmented reality
. If you’re looking for nearby food (or anything, really), Yelp is a great (free) way to find your best options.
The one thing Yelp won’t do is hand you a menu for the restaurants it suggests, and that’s where MenuPages comes in. While it can feel a little clunky at times, it’s indispensable when you’re in need of a menu on the go.
IMDb is a great resources for movie information, and the app does a good job of focusing a lot of information onto your iPhone’s small screen. What’s also great about the IMDb app is that it also serves as an excellent free option for finding movie showtimes.
TV Forecast performs the simple function of keeping track of when the next episode of any show is going to air. Enter in just about any show that’s currently running and TV Forecast will provide you with an attractive schedule tailored just for you. While you can grab the free version of TV Listings instead and save yourself $1.99, TV Forecast is a better option.
While you can always watch Netflix on your jailbroken iPhone with a little work, if you’re looking for a way to manage your old-fashioned Netflix queue you can do that nicely with PhoneFlicks. The functionality here is pretty basic, letting you edit your queue and find new titles through search or browsing, but it gets the job done and doesn’t cost you a penny.
Art and Photography
If you’re looking for a free, full-featured iPhone camera upgrade you should check out Joby’s Gorillacam. It provides a huge set of features, including a self-timer, time-lapse photography, anti-shake, three-shot burst, and more. Update: We’re hearing that Gorillacam may have a potential spyware issue. While we can’t tell for certain, you may want to proceed with caution.
If you really want to make the most of your iPhone’s camera, check out Snapture. It might set you back $1.99, but it’s a popular alternative to the iPhone’s built-in camera app. In addition to helping you take better photos, you’ll also find some basic image editing tools. Snapture’s main draw, however, is how easy it makes it to quickly pull out your iPhone and take a picture. Simply open the app, tap the screen, and you’ve got a photo.
HipstaMatic aims to emulate old cameras and film stocks, providing some pretty compelling results. But be warned: it’s one of those apps that can get pretty addictive, and you can shell out $1 each time you want to try out a new lens or flash.
Pano’s one of the more expensive apps in the list, at $3, but it can create some enormous, impressive panoramas right on your iPhone. It works by taking multiple shots and stitching them together. While the results aren’t always perfect, they’re often stunning.
While SketchBook is the sort of app that excels on a big screen, like the iPad’s, it’s nonetheless a great drawing app on the iPhone. With several brushes and pencils, you’ll be surprised what you can actually draw with this app. When you’re done, you can even export a PSD (Photoshop Document) or the flattened image. $3, but if you’re really into sketching, you’ll likely consider it worth the price.
With over 225,000 in the iTunes App Store it can be pretty tough to narrow it down. If you’ve got a great app suggestion we missed, share it in the comments.

10 Must Have iPad 2 Apps For New And Existing Users
What 10 years of Apple did to its main product
10 battery usage tips to hp pavilion dv8000 laptop user
Apple finally announced a new iPad that is slightly thicker and heavier than the iPad 2. The reason the new iPad is thicker is because Apple nearly doubled the battery capacity compared to last year’s model.
The new iPad has a 42.5-watt-hour battery. By comparison, the iPad 2 has a 25-watt-hour battery. The iPhone 4S, a smaller iOS device, has a 5.3-watt-hour Apple A1175 Battery, though it uses a lot less energy given its smaller screen.
Despite the bigger battery, the new iPad boasts the same battery life as the iPad 2. Apple claims the new iPad has the same 10 hours of battery life as the iPad 2 when web browsing over WiFi. Like the iPad 2 3G, the new iPad can run for up to nine hours using 4G LTE, mobile broadband that provides download speeds that are several times faster than 3G. Apple is very conservative in terms of its battery life estimates, with many iPad 2 users see more than 10 hours of extended life battery performance depending on their settings and usage scenarios.

HP elitebook 2730p battery brand new 5200mAh Only AU $74.89
The new iPad runs for the same amount of time with the larger battery because of the new Retina Display, which has four times as many pixels as the iPad 2′s display. The extra pixels requires a lot of power. The new A5X CPU, Apple’s new faster mobile processor, uses more energy than the processor found in previous iPads.
While Apple A1189 Battery life is important when making mobile gadget purchases, it’s far from the only factor. The new iPad outperforms previous models in every measure. The two most important features of the new iPad are the Retina Display and the new optional 4G LTE.
Apple.com was inundated with iPad buyers just after Apple announced the new iPad, temporarily crashing the pre-order pages. But not everyone’s so eager to spend $499 or more on a gadget that at first glance looks identical to the iPad 2. Here’s a guide that may help you decide if you should buy a new iPad. Here’s another guide that will help iPad owners decide if it’s worth upgrading from the iPad 2.

Improve laptop battery life and performance ultimate instructions
Dell has launched the V131, a new ultraportable laptop in its small-business Vostro line that the company says improves on the poor laptop battery life of its predecessor, the Vostro V130.
Dell has launched the V131, a new ultraportable laptop in its small-business Vostro line.
The Vostro V131, unveiled on Thursday, lets customers replace laptop batteries themselves and also offers lengthier battery life. The V130’s six-cell laptop battery lasted just over two hours with continuous video playback, but Dell said in a battery blog post that the V131 could manage almost 10 hours on a single charge.
“Overall battery life is much improved compared to the V130, thanks in no small part to Intel’s second-generation Core technology, which you may know as Sandy Bridge,” Dell blogger Lionel Menchaca wrote.

The V131 has three Intel processor options, including the ultra-low voltage Celeron 847 and the standard-voltage Core i3-2310M and Core i5-2410M. Customers can select four-cell or six-cell batteries.
Other features include an HD webcam with dual-array microphones, SRS Premium Voice Pro audio software, a fingerprint reader and a fall sensor for the hard drive. Although US customers can only choose configurations with hard drives, SSD options are available in some countries, including the Austrlia and UK.
The Dell Vostro V131 is on sale at a starting price of £359 excluding VAT and shipping, although its price can go much higher depending on the configuration.

Lithium-ion batteries are incredibly popular these days. You can find them in laptops, PDAs, cell phones and iPods. They’re so common because, pound for pound, they’re some of the most energetic rechargeable batteries available.
Lithium-ion batteries have also been in the news lately. That’s because these batteries have the ability to burst into flames occasionally. It’s not very common — just two or three battery packs per million have a problem — but when it happens, it’s extreme. In some situations, the failure rate can rise, and when that happens you end up with a worldwide battery recall that can cost manufacturers millions of dollars.
So the question is, what makes these batteries so energetic and so popular? How do they burst into flame? And is there anything you can do to prevent the problem or help your batteries last longer? In this article, we’ll answer these questions and more.
Lithium-ion batteries are popular because they have a number of important advantages over competing technologies:
- They’re generally much lighter than other types of rechargeable batteries of the same size. The electrodes of a lithium-ion battery are made of lightweight lithium and carbon. Lithium is also a highly reactive element, meaning that a lot of energy can be stored in its atomic bonds. This translates into a very high energy density for lithium-ion batteries.Here is a way to get a perspective on the energy density. A typical lithium-ion battery can store 150 watt-hours of electricity in 1 kilogram of battery. A NiMH (nickel-metal hydride) battery pack can store perhaps 100 watt-hours per kilogram, although 60 to 70 watt-hours might be more typical. A lead-acid HP Business notebook 6710b battery can store only 25 watt-hours per kilogram. Using lead-acid technology, it takes 6 kilograms to store the same amount of energy that a 1 kilogram lithium-ion battery can handle. That’s a huge difference. batteries to suit your lifestyple batteries-company.com – your best batteries online shop for HP laptop batteries, Toshiba laptop batteries, Dell laptop batteries, Asus laptop batteries, HP laptop AC adapters and Dell laptop AC adapters, all our notebook batteries and laptop power adapters are 100% satisfation guarantee and 100% brand new with 1 year warranty!
- They hold their charge. A lithium-ion HP Pavilion dv9000 battery pack loses only about 5 percent of its charge per month, compared to a 20 percent loss per month for NiMH batteries.
- They have no memory effect, which means that you do not have to completely discharge them before recharging, as with some other battery chemistries.
- Lithium-ion batteries can handle hundreds of charge/discharge cycles.
That is not to say that lithium-ion batteries are flawless. They have a few disadvantages as well:
- They start degrading as soon as they leave the factory. They will only last two or three years from the date of manufacture whether you use them or not.
- They are extremely sensitive to high temperatures. Heat causes lithium-ion battery packs to degrade much faster than they normally would.
- If you completely discharge a lithium-ion battery, it is ruined.
- A lithium-ion battery pack must have an on-board computer to manage the battery. This makes them even more expensive than they already are.
- There is a small chance that, if a lithium-ion battery pack fails, it will burst into flame.
Many of these characteristics can be understood by looking at the chemistry inside a lithium-ion cell. We’ll look at this next.
