While purchasing Laptops in addition to the regular hardwares you need to be mindful of the following things:-

• Weight
• Size
• Display Size
• Battery Life
• Battery type

Weight :  Nearly all laptops sold today fall in the range of 4 to 7 pounds. The heavier laptops have more features. The lighter models may have fewer features or merely more advanced features, but they’re generally more expensive. You pay more for light weight, but oddly enough you pay more for extra weight too, thanks to the added features.

Size: Most laptops are less than 1 inch thick and about as tall and wide as a small coffee table book. They could get smaller than that, but there is a limit based on the size of the keyboard and the size of the display. Speaking of which. . . .

Display :. Recently, manufacturers have discovered that people love larger LCD displays on a laptop — despite the larger display adding to the laptop’s size and weight. For a laptop being used at one location and only rarely going on the road, a huge display is wonderful. But if you want portability, and a longer battery life, consider a smaller display.

Battery life : Despite the claims on the brochure, most PC laptops last anywhere from two to three hours unplugged. They last even less if you do a lot with the laptop, which means lots of disk access and networking and stuff that requires copious amounts of electricity.

Battery type : There are many types of batteries, but what you want in your laptop is a Lithium-Ion battery. You do not want a Nickel-Cadmium or “NiCad” battery. The Lithium-Ion batteries can be recharged at any time and don’t have the “memory” problem of NiCads. They also last longer and keep a more potent charge longer.
