low battery life on my dv6tse

Hey guys,



I have a DV6TSE with:



i5 450M

hd5470 / intel switchable

6gb DDR2

500gb 7200rpm

backlit keyboard/finger print reader



I'm only getting about 2-2.3 hours max on a 6 cell battery, and I only use this computer for word processing, or web surfing. I've read of people getting averages of 3-5 hours for the 6 cell, should I contact HP?



Thanks
