Select the brand of laptop which you want to purchase and then decide the size and choose as per your requirements.
Select the laptops at the store. Select one that feels sturdy, solid and not too heavy.
Always try using the keyboard at the store as you cannot replace it, make sure you are comfortable with its quality and feel. Try it on a desk and on your lap.
Check the pointing device, track pad or track ball. Some of these can be difficult to handle. You will be able to connect an external mouse, but the built-in device which is handier when you’re mobile.
Check if the computer’s bottom gets immediately hot when it is running–a problem if you actually use the laptop on your lap. Please also check whether it gets hot to a greater extent too.
Pay close attention to desktop size and resolution. Presently liquid-crystal display (LCD) screens on laptops measure from 13 to 21 inches diagonally. Screen resolution may be as low as 800 x 600 pixels or as high as 1600 x 1200. Have a look at the screen in a variety of settings: A screen that looks great in normal room lighting can look terrible in bright or dim light.
Purchase a laptop which has at least two USB 2 connections and at least one Firewire (IEEE1394) connection. USB 2 and Firewire are very popular and fast ways of connecting iPods, digital cameras and some phones to computers.
Test to see if the laptop has built in wireless technology. A wireless network card and also Bluetooth capability will let you share information wirelessly with other Bluetooth-equipped devices, such as your cell phone or personal digital assistant.
Make sure your laptop has a DVD Burner. That makes backing up documents, music files and pictures a snap because of the high capacity of the discs.
Assure that you get an antitheft device installed in the laptop. Look for cables that secure the laptop to a desk. Install software that disables a stolen laptop, or better yet, reports the laptop’s location when it connects to the Internet.
