The time and date on my computer keep changing themselves. How do I solve
this problem?
First take note of when the change takes place. Beware of any advice
you may get to change the battery, which may or may not be correct. If
the date and time stay correct while the machine is running, the
problem can not be the battery, because the battery isn't used while
the computer is running.
But if the clock lose time every time you power on, almost certainly
the problem is the motherboard battery. It's a small flat disc,
roughly the size of a US quarter. A new one costs only a few dollars
and they are easy to change--consult your manual for instructions.
