I've recently (about december) begun to have this problem. The clock will be about inbetween 5 to 10 hours after shutdown time when I boot it. I thought it was the batery, and I know it recharges during the time while the computer's on. I left my computer on for a whole day hoping it would work, and it didn't. I would like to know if theres anyway to fix this without using any external clock program or switching the bateries.

Thank you in advance.

Ok thanks... I was hoping not having to buy a new batery, but I guess I'll have to. Thanks again
