I have two PC's running Ultimate. One appears to keep good time, the other
loses the correct date and time if left turned off for a few days.
On the problem PC, I have verified that the CMOS battery is good, and that
other BIOS settings are not lost during off periods. The only difference I
can find between the two computers is that on the one that works, Internet
Time is set to time.windows.com and on the other PC it's set to
time-a.nist.gov.
With the time-a.nist.gov selected, clicking on Update Now works, but with
time.windows.com, clicking on Update Now returns an error.

Any ideas or pointers on this situation?

Can't you change the internet time setting to time-a.nist.gov on the system
that you are having the problem with?

I'm sorry. I didn't make myself clear. The PC set to time-a.nist.gov is the
problem PC. The one set to time.windows.com is OK.

OK...but I think JW's point was to just set both PCs to the time server that
works. Have you tried that?

I'm testing that now. I set the problem PC to time.vista.com, then turned it
off. I'll turn it on tomorrow and share the results.
Thank you both for the suggestions.

It won't always sync time when it boots. You'll need to force it explicity.

if it losing time when it is OFF, it is the battery.

I'm not trying to be argumentative here, but if my custom BIOS settings remain intact, does that not indicate the battery is doing its job?
If I'm wrong in this assumption, please educate me.

I believe that at least some motherboards store most of the BIOS setting in nonvolatile flash memory, no battery needed to maintain it.
However, I have not tried seeing what happens if I remove my battery so cannot say that I actually KNOW that.

Obviously, I don't have my facts straight here. I got a new battery and set the clock, then shut down and removed power for an hour. With the new battery, the clock is correct. Thanks very much for your comment!

you are welcome,
most newer motherboards use a form of ERAM to save the bios settings in.
only thing not saved is the clock.
