This is a little off topic. But when I disconnect the power, I loose the
CMOS settings. Shouldn't the battery on the MB prevent this? Is the battery
likely dead?

Yes, the battery on the motherboard is to keep your CMOS settings when
there is no power to the computer. If the settings aren't being
retained, replace the battery (approx. $3-5USD so very inexpensive).

Yes, that's its purpose.




Almost certainly.

Just so I don't loose the CMOS settings, can I remove the battery while
there is some power to the machine -while the machine is off?

That would be very foolish. Best practice is to unplug the power cord
from a machine while you work on its innards. If you pop the battery
out and immediately put a new one in, you may not lose settings.
However, if you are worried about it take 5 minutes and write the
settings down.

I wouldn't put my hands inside the box while the power cord is plugged in.
There is danger both to yourself and to the computer that way.
