Optical Device (cd, dvd, dvd cd r/w ,dvd writer) :
Most laptops these days come with a dvd cdr/w commonly called as a combo drive .This is considered a bare essential these days .Indeed a writer is must these days since it comes in very handy to backup or carry data along. The latest laptops these days come with a Dvd R/w .They usually come with a slower speed as compared to desktops as on date the maximum speed available is 8x while on desktops speed of 16x is also available .Look for dual layer support which will help you write dvds up to 8.4 gb capacity against the normal 4.7 gb capacity .

Pointing Device (Stick /Touchpad) :
Look for the following:

   1) Does it have a touchpad a pointing stick or both ?

   2) Does it come with horizontal and vertical scroll support on the touch pad ?

Battery :
Battery is one the most important consumable of a laptop . Check if the battery is li-on or ni-mh( only for old laptops as all new laptops come with li-on battery) .In new laptops check if the laptop comes with a 6-cell ( most common) or 9 -cell ( some laptops) or 12 cell (very few laptops) battery , naturally the more cells the more battery life you get. Also if you are a very mobile user check if the laptop has an option to take in additional battery .You may also want to check the price of additional battery pack .

Warranty and Service :
One very important criteria. The warranty on a laptop is a very crucial criteria .Try to buy a laptop with 3 years warranty since servicing a laptop can be usually very expensive ,if you are buying a one year warranty laptop , ask about what are the charges per year for extended warranty .Usually such extensions are expensive so try to buy a laptop with 3 years warranty .Also check if the warranty is global or local .Most laptops come with global warranty which is preferable over local.
