Resolved cmos checksum error

Thanks for all your help and suggestions

 

Did you get it fixed and if so, what fixed it?

 

I agree that the CMOS battery was/is the most likely culprit. but the problem never happened again and I am reluctant to mess with someone else's computer unless it's dead. My hands are not as steady and reliable as they once were, so if the problem surfaces again I'll take it to the shop.

If it ain't broke, don't fix it, or don't keep fixing it 'til it's broke. I listed the thread as solved, although technically I guess it isn't, but time will tell.

Thanks again for your interest.
