How old is the battery? On our laptop computers, if the battery maintains itself for a couple of years, then we count ourselves lucky.. Anything longer than that, the charge status reduces quickly during normal operations. You may need a new one.
Another note: If you aren't already, be sure to reduce the screen brightness during battery operation.. The screen brightness uses a fair amount of power.. Also, make sure you don't have any programs running that might be drawing down the power.. Don't keep a CD/DVD in the drive unless you're using it.. ETC.
Hope this helps.
