Laptop Tips - Quick Way to Buy Most Reliable Laptops

If you’re a parent like me who works from home, then you know how crippling it can be when your computer breaks down. 
I nearly went insane the last two weeks waiting for Sony to fix my laptop. This is the second time I’ve had a big issue with my machine and couldn’t write my stories.
 I’m hoping my next purchase proves more reliable.
What will I buy next? I don’t know much about computers, so I decided to call Dean Gallea, Senior Program Leader at Consumer Reports, to see which brands the publication recommends. It turns out that every year the magazine runs an Annual Product Reliability Survey that asks 43,000 laptop owners about their experience. Here’s what Gallea and his team discovered:
PC Users
If you like using a PC, Toshiba and Acer are tied as the most reliable brands for laptops, says Gallea. Owners reported needing a repair or having serious problems with their models just 15% of the time.
So which models should you buy? In the 13-inch laptop category, Consumer Reports recommends two Toshiba models as “Best Buys”. For $700 you can get a Toshiba Portege, which has an “Excellent” performance rating. For just $400, you could pick up a Toshiba Satellite, which gets a “Very Good” mark for performance.
If you want a 14-inch laptop, Consumer Reports again recommends the Toshiba Satellite. The larger size costs a bit more at $750. But it also scores an “Excellent” on performance.
In the 15 and 16-inch category, the Acer Aspire isn’t a Consumer Reports top pick but it costs just $620 and also gets an “Excellent” for performance.
How important is computer reliability to you?

Apple is rolling out a subscription service for content

In a widely expected move, Apple is rolling out a subscription service for content-based apps such as magazines, videos, music and newspapers. The service is already present in News Corp’s The Daily, a publication tailored specially for the iPad.
Publishers will have the ability to set a subscription’s price and duration, while customers can select the length of their subscription. Beyond that, Apple has set a few more rules for the new service.
“Our philosophy is simple—when Apple brings a new subscriber to the app, Apple earns a 30 percent share; when the publisher brings an existing or new subscriber to the app, the publisher keeps 100 percent and Apple earns nothing,” Apple CEO Steve Jobs wrote in a Feb. 15 statement. “All we require is that, if a publisher is making a subscription offer outside of the app, the same (or better) offer be made inside the app, so that customers can easily subscribe with one-click right in the app.”
Apple’s subscription service appears at a transitional moment for digital periodicals. On Feb. 2, Apple and News Corp launched The Daily, a tablet-only newspaper, in New York City. Priced at 99 cents per week (and $39.99 per year), the publication offers built-in games, weather updates, a customizable sports dashboard, interactive video and photos, and stories read aloud. Whether or not The Daily succeeds, its model—combining text with interactive content, formatted to a 7-inch or 10-inch screen—will be one almost certainly followed by rivals in the near- and long-term.http://www.bestlaptopbattery.co.uk

From that perspective, the integration of an app subscription service seems a logical move. But Apple’s newfound insistence on in-app purchasing has the potential to complicate life for app creators, as the company’s relationship with e-book publishers has already demonstrated.
Earlier in February, Apple started ratcheting up its policy enforcement for e-book apps, stating that app-makers such as Sony and Amazon needed to offer in-app purchasing through Apple’s online storefront if they wanted to make e-books purchased on other devices available through the iPhone, iPad and other Apple products.
“We have not changed our developer terms or guidelines,” Trudy Muller, a spokesperson for Apple, wrote in a statement posted on Bloomberg and other media outlets Feb. 1. “We are now requiring that if an app offers customers the ability to purchase books outside of the app, that same option is also available to customers … with in-app purchase.”

Presumably, should those companies refuse to offer the ability to purchase e-books via the in-app option—which has the potential to earn Apple up to 30 percent of the sales price—they could face the possibility that e-books purchased via a Website might be unavailable on an Apple device. A disagreement over terms between Apple and Sony apparently led to the banning of Sony’s e-reader app from the App Store.
“Unfortunately, with little notice, Apple changed the way it enforces its rules, and this will prevent the current version of the Reader for iPhone from being available in the app store,” read a note on Sony’s online Reader Store. “We opened a dialog with Apple to see if we can come up with an equitable resolution but reached an impasse at this time.”

Battery Care - Regular Battery Maintenance Can Prolong Battery Life

If regular battery maintenance isn't part of your car care routine, you may be heading for a stall. Regular inspections and maintenance of your car's battery can help ensure safe and reliable starts, in both hot and cold climates.bestlaptopbattery.co.uk Lead in UK laptop battery
Batteries Plus stores offer free hp dv9000 Battery and electrical system testing in addition to a visual inspection of your car battery to look for common problems such as corrosion, poor connectors and failed hold downs that can affect battery performance.
"Even if you don't have to cope with winter weather where you live," said Russ Reynolds, CEO of Batteries Plus, "heat and humidity can cause battery problems, too. The bottom line is that it's no fun having to deal with a dead battery, no matter what the weather. That's why we recommend having your car's battery checked every three to six months."
Reynolds offers these battery inspection and maintenance tips designed to maximize the life of your Hp hstnn-db42 battery and improve its performance in any climate. Note: If you attempt battery maintenance yourself, always wear proper eye, hand and body protection to help prevent burns and serious injury from the acid and corrosive chemicals inside the battery.Welcome to http://www.bestlaptopbattery.co.uk

Tip 1: Loose battery hold-downs leave the battery subject to vibrations, which can cause the active material to shed from the car battery plate grids, resulting in a shorter dell xps m1730 battery life.
What to do:
  • Secure the battery firmly to its mounting bracket.
Tip 2: Corroded terminals resulting from sulfuric acid overflows from the lead acid cells within the battery, or moisture buildups, can also cause a car battery to fail over time.
What to do:
  • Check the terminals where the battery cables connect and make sure they are tight and corrosion-free. If you see corrosion, ask a qualified technician to fix the problem.
  • Keep terminal clamps clean. If you see an accumulation of a powdery, white substance around the electrodes, use baking soda and water to clean the clamps.
  • Prevent future corrosion by using an anti-corrosion spray on the exposed metal parts of the terminals and cables.  laptop battery from bestlaptopbattery.co.uk
Tip 3: Visible swelling, cracks or vents in your battery's case are an indication that the battery is failing and should be replaced.
  • Do a visual inspection of your dell xps m1330 battery regularly. If you see indications of battery failure, have your battery checked by a qualified technician and replaced if necessary.
  • Keep your battery clean. Even small amounts of dirt deposited on the battery can lead to a power "leak" and cause uncontrolled discharge and power loss.

New battery technology from Argonne helps laptop-last longer

battery technology from http://www.bestlaptopbattery.co.uk
This month, thousands of new Chevy Volt owners will begin the real road tests of the first mass-produced plug-in hybrid electric car. While much of the car's engineering is unique, consumers may be unaware that some of its most extraordinary technology is inside the nearly 400-lb. battery that powers the vehicle in electric mode.
The battery's chemistry is based in part on a revolutionary  breakthrough  pioneered by scientists at the U.S. Department of  Energy's Argonne  National Laboratory. The new development helps  the Volt's battery-a  lithium-ion design similar to those in your cell phone or laptop-last  longer, run more safely and perform better than batteries currently on the  market.
"To me this cuts right to the heart of green energy," said Jeff Chamberlain,  who heads Argonne's battery research and development. "This battery  technology is a step towards energy independence for the U.S.; it helps create jobs; and it can have a positive impact on the environment."

The story begins in the late 1990s, when the DOE's Office of Basic Energy Sciences funded an intensive study oflithium-ion batteries.
"Existing materials weren't good enough for a high-range vehicle," explained Michael Thackeray, an Argonne Distinguished Fellow who is one of the holders of the original patent. "The Argonne materials take a big step forward in extending the range for an electric vehicle."
In order to improve the design, scientists had to know how batteries worked at the atomic level.
