I bought an Inspiron 1525 laptop a few months ago with Windows Vista Home Premium.  About a month ago I noticed that the clock on my laptop started losing time.  Now it loses almost 1 hour for every 4 hours that I'm working on it and its driving me nuts!  I am not sure if this is something wrong with the laptop or if its a Vista issue.  If anyone else has had this problem (or heard of it) and know how to solve the problem, I would really appreciate your help.  Thanks!!
