and eyeball the little coin type battery located usually on the lower corner of the motherboard. I would guess a CR 2032?
i run XP home on a HP 7920 celeron, 256 mg mem. It's four years old and has been great. No virus. Little malware. The only problem I have encountered is it's starting to lose time on clock. A little at first , maybe started noticing it 2 months ago now I set it Sunday and it's now lost 17 hrs.I heard it could be a battery but I can't find any documentation abut it and run sys scan through Belarc advisor and it lists everything but. Can someone tell me where this battery is located and how to find the correct type of new one? And where do you buy desktop PC batteries?
