The "internet time" I referred to is that little clock dealie in the lower right hand corner. I thought it was supposed to reset off the net every time you booted. But, I rarely actually reboot, since I bring the machine up from "Hibernate" most of the time.
And it wasn't a matter of a couple of milliseconds, it was about two hours.
So, OK, possibly the BIOS battery, but right after I posted, I did a full MSE scan. It popped up with "your computer is potentially unprotected." Now, this could be because the last time I updated was Saturday, but that seems like a pretty short time for MSE to be outdated.
But my first concern was if something outside the machine was goofy or if it was internal, like malware screwing up the time.
I know most malware makers don't mess up your machine --they don't want you to realize something's wrong --but it's been acting "funny" lately. Mouse suddenly quitting and having to reload sites.
I guess it's a good bet, as you said, that the BIOS battery is going bad, but I didn't think this was supposed to happen nowadays and I;ve only had the thing for about four years. Of course, it could have been sitting on a shelf or something for a while before I bought it.
So. It looks like I'd better keep my backups updated a little more often, and wait. Or buy a new one. Or figure out how to install a new battery. (I've done that before with another piece of equipment.)
So thanks, folks. Appreciate your input.
