Hi,
If you have HP Support Assistant installed, you can use this to run a test on the battery.
If you don't have HPSA, download and run the stand-alone battery test utility available on the page below and see if this reports any problems with your battery.

Hi,
Try manually callibrating the battery as described in the document on the following link - although the document refers to Vista, it's the same for Windows 7.
