system clock changing randomly

the system clock on a friends computer changes to a random time, whilst the machine is off. is it just the backup battery or could it be something else

How old is the PC / motherboard?

Does sound like a dead/dying battery. Do any of the other CMOS settings change when the date/time does. This would also point to the battery failing.

it's about 2 years old, which isn't very old for a battery to fail, but thinking about it the friend was very ill for about 3 months last year so i guess it would have used more battery life than most in that period
