[amsat-bb] Re: PC clock

[Greg D.]

Hi Larry,

I know PC clocks are not all that accurate, but we're talking seconds per month.  Needing to update a clock more often than that probably isn't due to the PC hardware.  I've never had one be off this much unless the clock battery was dead, and any PC new enough to run Win-7 isn't going to have that issue.  I would suspect that there is a some software you are running that is messing it up.  Back in the DOS days, this was a common occurrence, and I'm surprised to hear about it under something more modern, but my gut feel tells me that is what is happening.

Maybe a device driver or something else low-level.  Try booting something else (a "Live" CD of Linux, for example) to prove the hardware is good.  Go back to Windows piece by piece.  If you can figure out which it is, then this whole idea of applying bandaids can go away.

Just a thought,

Greg  KO6TH
