Ah shows the capacity of amp movement in an hour. Level of this unit determines use time of laptop with battery. Of course power requirements of your laptop affect life of the battery. This is while some laptops (heavy configured multimedia laptops) have 2-3 hours of life during some other laptops (especially ones with small screen or SSD) can have battery usage time up to 8 hours even though they all use the same battery. Also most of the laptop brands offer an extra accessory option named Double battery that provides twice amps per hour when compared to normal ones.

There two main graphics card chip producers; ATI and Nvidia. Whichever you choose, if you want to have high graphics process capacity and speed you need to know how much memory your graphics card have. Most of the laptops use graphics card with shared memory (uses from RAM as much as it needs, mostly up to 2 GB) which can not serve as a gamers’ purposes, integrated graphics card are not for gamers.

USB Ports and Extra Connection Points:

Be careful about the number of your laptops USB ports and versions. It’s ideal to have at least three USB ports, more is welcome. USB 2.0 is the latest version, check if your laptop has this fast data transfer standard.

Because eSata connection speed is way faster than USB. This is why you should prefer laptops with USB 2.0 / eSata convertible ports or independent eSata ports. HDMI output allows connection to an external display device. HDMI is the latest video connection technology, transfers display data in a digital way. Another feature of HDMI is it also transfers audio data. Like USB there are different versions of HDMI. Be careful while buying a laptop with HDMI port, 1.3 is the latest version.
