Netbooks: In The Strange Place Between Laptops And Smartphones

It seems everywhere you will look companies are hawking their new, tiny, travel-ready netbooks. Wireless companies and cable companies are offering them as incentives in exchange for a service contract and Nokia announced a few weeks ago that they’re working on a version of their own.

They look enticing: Why lug around a regular laptop when a slim,well battery like Dell GK479 sexy thing would keep you connected at the airport or in a far-flung hotel room. But I kept asking myself the same question over and over: If these machines are made almost exclusively for web browsing, why would I use a netbook instead of a smartphone?

I looked at two of these netbooks: Verizon’s HP mini 1000 and AT&T’s Acer Aspire One. For the most part, all these netbooks have about the same specs. Both of these had 2 gig intel atom processor and 1 GB of memory and nice battery HSTNN-LB31.So, the startup process is zippy and roaming the net is a pleasure.I have feeling he’s the market segment netbooks will speak to: People who want little e-mail machines, people who, with the exception of a rare YouTube video, won’t be doing much in the way of multimedia.

Both netbooks had nice, bright screens and both of them featured a smaller than normal keyboard that took some getting used to but was definitely more comfortable than the keyboard of even the roomiest of phones. The HP Mini is definitely better looking, mostly because the Acer One has a protruding battery Acer BTP-42C1 that only a parent could love. But I don’t think a regular user could find very many things that would make one a better choice over the other.

With a built in 3G connection, these netbooks offer amazing portability and the connection is fast enough that you won’t get frustrated watching a video. And that’s one of the huge perks: You can download a flash plug-in and watch internet video to your heart’s delight. It’s also nice that you can install different browsers and use a feature-filled application like Skype.(more imfor:Aspire 3000 battery……;)

Both netbooks had met their match. Their specs were just under the minimum requirements and I found my answer: If something’s going to take up more than pocket space, it better have enough oomph to let you experience the web’s full richness.

Why it is useless about the Laptop Battery Claims

It’s one of those things we take for granted: official laptop battery life claims have an extremely tenuous relationship with reality. Not surprisingly, everyone’s using the same tricks to conjure their silly estimates—and they don’t plan on stopping.

AMD, as part of a some kind of PR campaign, is saying the culprit is a battery testing suite called MobileMark 2007:
the parameters for this test include having the screen at just 20 percent brightness, Wi-Fi turned off and no music, video, games or Web pages running. More or less, the test turns a computer into a dimly lit clock, then sees how long it can run like Dell GK479.

That is exactly the kind of test you’d have to run to hit Sony VGP-BPS2C 50-100%-inflated figures, and the perceived ubiquity of the test gives it an air of authority—or at least respectability—within the industry. Using anything more honest would put a manufacturer at a competitive disadvantage.

Whenever I want to learn more about a particular battery chemistry, I refer to this book “Batteries in a Portable World.” You can pickup a print version on Amazon for $4.75. The book is also available for free on-line. It contains a wealth of information,many kinds of batteries such as Dell GD761,Latitude D620 battery…….

Here are a few more tips for getting the longest life from the lithium-based batteries in your laptops and power tools:

• Avoid heat
• Remove the battery when using a power supply for a extended duration
• When not in use, store the battery at a 40 percent charge and keep it in the refrigerator (do not freeze)
• Buy fresh batteries from a retailer who sells a lot of batteries ThinkPad T60 battery and so on. (avoid old batteries)
• A full discharge after every 30 charges will help recalibrate the battery

This is where the story lapses into accusations of subterfuge: AMD says these tests don’t just benefit laptop manufacturers in general—they’re unfairly biased towards Intel, whose chips are optimized for these less-than-realistic scenarios. It’s easy to see how this would be upsetting, but it’s not clear what AMD can really do. They’re proposing a system by which manufacturers show two battery ratings—one the shows a theoretical, low-use maximum, and one that reflects heavy use. (To their credit, Sony already does something like that). Dell inspiron 700m battery admits the practice, but is predictably standoffish about it, while AMD doesn’t inspire much confidence:
By 2010 or 2011, something might show up from a consortium that could be used. It takes two to three years.”
Well, thanks for trying, I guess!
