I have the above model laptop and been having trouble with the battery for almost six months now. The battery no longer seems to hold a charge. When not plugged in the battery will boot up to windows xp loading screen the switch off. However, the same thing happens when I take the battery out and it is just plugged into the AC. Furthermore, when I have lots of apps open at once the battery warning keeps flicking on and off from using battery (@ 2%) to AC. what the heck is wrong? Surely it should just work if it is plugged into the mains and the battery is unplugged? I don't travel with it so if I could just get rid of the annoying beep then it would be perfect!
