taskbar clock

[Guest]

For about a week now my taskbar clock has not been updating from day to day.
When I reset it, the next day it's still at the time I reset it the day
before. The date has been jumping around crazily from 2001 to 2025. When I
check with the "time" command at the dos prompt the time shown is identical
to that at the taskbar clock.
Is this an indication that my CMOS battery is going or do I have another
problem?

If it loses time while shut down then the CMOS battery has to be replaced.

If I understand you correctly, yes, it sounds like you need to replace the
battery. If the clock loses time while powered off, it's very likely that
it's the battery. But if it loses time while Windows is running, it can
*not* be the battery.

When I update the clock in windows it runs for at the most 20 or so minutes
and then stops. The checksum at bootup is always good so if the CMOS battery
was bad the system settings would be lost after shutdown. Right?

No. Batteries often fail gradually, so all system settings aren't
necessarily lost at once. The clock settings are often the first to go. But
if I understand you correctly this time, your problem occurs while the
computer is running, which means the problem can not be the battery.

I checked the sys temp. It's 29C/84F, well within guidelines. CPU temp is
51C/123F again within specs.? I haven't had a checksum error at bootup so I
don't think it;s the CMOS battery any more. What else?

Wouldn't I get a checksum error at bootup if that was the case?

It's done both. Quite a few times I've reset the clock only to check an hour
latter to find it has stopped. What next?

I would suspect the clock/motherboard has a problem then.
