85777 2002-10-03 12:36:00 The system clock on my computer (PII 333) is continually losing time although a system utility tells me that it is working okay. I assume that the battery is running low, where do I find it, and is it simply a matter of swapping it over? Also, are they Mother board specific? taylor (2136)
85778 2002-10-03 13:01:00 Yes, it's very likely your battery is running down. When your PC is on the clock is working fine as you've discovered, but when it's turned off the BIOS clock is relying on the battery to keep it accurate. Not sure about your motherboard's vintage, but at a guess I would say it is a 'button' type battery in a little holder on the motherboard and quite easily replaced. On older motherboards (486 CPU and earlier) the battery could be soldered onto the board and it isn't so easy to replace. You will just have to look all over your motherboard for it, it shouldn't be too hard to spot. Rod J (451)

Rod's advice is correct. Your battery should look about the size of a 10 cent piece, and its silver. Looks a bit like an oversized watch battery. They're usually just clipped in, and should be fairly easy to remove and replace.

It should be something like "CR2032". You can get these at most supermarket battery centres or at camera shops. Taking the old cell out will probably require a screwdriver and some force and you will have to make sure the terminals still make good contact once you have put the new one in. However, some motherboards are not very good at keeping time even with a good battery so this may not even solve your problem.

If you have an always-on internet connection and Windows XP then there is an easier solution. You can enable time-synchronisation with an internet time server in the date/time properties.
The default update interval is one week, which is a bit long, but it can be changed to something more suitable using a registry setting. I can't remember exactly where the setting is off the top of my head, but I could look it up for you if you require.

I hope this helps.
