iBook Battery Issue

My laptop has been fine for a long time, but it recently started to turn off/lose power if the computer is bumped even slightly in the right spot.

Does anyone have an issue with the iBook being very sensitive to movement? My laptop has been fine for a long time, but it recently started to turn off/lose power if the computer is bumped even slightly in the right spot. I can walk to class with the computer sleeping in my backpack and be fine. Sometimes when my knee bumps the battery pack it will turn the computer off. Or, sometimes if I'm passing the computer to someone else and they set it down on a table-top it will turn off. It's annoying. The battery is installed properly.

Anyone have this issue? Any solutions?

Thanks,
