My netbook is about six months old. The battery itself seems fine, but the power icon always reads either full power, or zero power. I've been trying to figure out when it reads what, and it seems like it reads full power after letting it charge overnight which is normal, but once I start using the battery power it doesn't gradually go down. Instead, once I shut it down and then reboot it, if its not at full power it reads 0%. It'll run fine at 0%, then eventually die without any warning. I never run the laptop for longer than an hour or three a day, so I don't know if I'm not getting a full charge or anything (I'm supposed to get like 6 hours of battery life.) Any ideas on how to get my battery power indicator working accurately again?
