I have a question, my lap top doesn't keep time right, it will lose 2 hours every now and then, I just re set it and it stays a few weeks and then does it again, I originally thought it was the internal battery but it doesn't do it all the time, It has been happening since the day I bought the lap top, I didn't worry about it cause every thing else worked fine, but I now run a G P S program that gives me a eta, if the time is wrong so is the eta, anybody have any ideas what it could be?
