My computer keeps losing track of time, and I've heard that this is a symptom of a dying CMOS battery. However, I don't want to bother with replacing my CMOS battery just to correct my computer's clock.

Is there anything important that the CMOS does besides powering the computer's clock?
 
You mean like keeping your bios settings? Nah :p

It's really not difficult, nor is it expensive to replace the battery...
 
It's a 5 dollar battery, if that. Very easy to replace.

The loss of time can sometimes be interpreted by Windows as a hack to get around activation time limits, and you may boot up one day to find out that 'your copy of Windows is not genuine.' Annoying; fixed with a new battery.
