Good tips for ensuring comfortable laptop ergonomics



Top Five tips for ensuring comfortable laptop ergonomics
-http://www. wholesaleeshop.com.au
That laptop of yours is mighty convenient, but it’s slowly killing you. Well, maybe not killing you, but it could be nudging you towards repetitive stress injury, eyestrain, and back problems.
1: Get your keyboard at a comfortable angle
Laptops used to come with little pop-out legs in the back to set the keyboard at an angle. (I’m really dating myself.) But these days, to position the keyboard at an angle, you can prop the back of the laptop on a small book or other widget.Acer eMachines D640(P321G32Mn) Laptop - wholesaleeshop.com.au
2: Make the screen brighter
Dim screens are better for battery life, but you’ll get a headache staring at a low-contrast screen for hours on end. Bring a power cable so you can plug in and crank the brightness until it’s comfortable to see.
3: Use a separate mouse
Integrated touchpads or pointing sticks are clumsy to use for extended periods. Invest in a small portable Bluetooth mouse. Likewise, many ergo experts advise using a separate keyboard, so you can position the laptop for optimum display position. This isn’t practical on the road, but you might consider it if you use the laptop as your primary PC in the office.
4: Position the laptop for the task at hand
If you’re doing a lot of typing, your wrists should be straight and elbows at a 90 degree angle, as if you were typing on a keyboard in the office. For many people, that might mean putting the laptopin your lap. But if you’re mainly reading, that’s a bad place for the screen. Instead, elevate it to near eye level. (You can put it on a stack of magazines or books.)
5: Carry it in comfort
Your laptop, mouse, power supply, and other accessories probably weigh anywhere from five to 10 pounds. Be sure to carry it all in a bag that has a wide, padded strap to distribute all that weight comfortably across your shoulder. Even better, consider a rolling case so you don’t have to carry it at all.

Google takes on e-books market – Bestlaptopbattery.co.uk

Google takes on e-books market Bestlaptopbattery.co.uk

The new online bookstore, dubbed Google eBooks, features 3 million titles, from newly released best-sellers to freely available out-of-copyright books, which consumers can store in a personal online library managed by Google and then read on any device.
“All of your library is there at anytime; any device you pick up, all your books are present,” James Crawford, the director of engineering on the Google Books team, told Reuters in an interview ahead of Monday’s announcement.
The electronic books market is currently dominated by Amazon.com, which helped establish the market with the release of its Kindle reading device in 2007 and has a roughly two-thirds share of the U.S. market, according to Forrester Research. Earlier this year, Apple entered the market, selling electronic versions of books that can be read on its popular iPad tablet PC.

Google has an opportunity to offer electronic books to a vast segment of consumers who might not have been aware of electronic books, said Forrester Research analyst James McQuivey. But he noted Google would have a better chance of unseating Barnes and Noble in the No. 2 spot selling digital books, than Amazon.
“The Kindle brand is solid and their devices are super-elegant, very cheap now, and their bookstore is second to none as far as bookstores go,” McQuivey said.
Google said its digital books are compatible with a number of reading devices, including the Barnes and Noble Nook and Sony e-reader, but are not compatible with the Kindle (save for titles in the public domain that do not rely on special digital rights management technology).
Google, whose Internet search algorithm has made it the world’s most popular search engine, has created a special algorithm to help it set the optimal price for its electronic books, said Crawford.
