I have three year old Sony Vaio laptop that I use at work.  The time in my BIOS moves back 4 to 5 mins after I reset the time.  I first noticed that my Windows time, Windows 7 pro, was reverting back 4 to 5 mins after I would change it so I checked the BIOS time.  Noticed that it was slow as well and made the change.  Within 10mins of making the change my Windows and BIOS time had moved back 5 mins.  


This isn't a huge deal, but it is kind of annoying.  I am assuming it is a motherboard battery issue, or is that a poor assumption?  If anyone has any thoughts would like to read them.

I agree with kaz20 that is probably a bad CMOS battery.  They only cost a few bucks to replace, so you should try that first.

This is a laptop, so changing the CMOS battery isn't necessarily as easy as on a desktop.  I know that HP machines use a battery with a connector soldered to it.
