cmos problems

[Will Rose]

Awhile back I was having the problem of my computer not booting up. It
wouldn't even get to the bios screen. I posted on here and was advised
to reset the cmos jumpers on the motherboard.

That worked fine a few times, but now the problem has returned and
resetting the cmos jumpers no longer works. Does anybody know what the
problem could be? As I understand there is a battery on the motherboard
that runs the cmos. Could the battery be dead? If so, how expensive is
it to fix?

Thanks.

Inspect all cards and cables for loose fit or elctrical
shorts. Examine the motherboard capacitors. If the power
supply is a generic (or eve if it isn't) take voltage
readings with a multimeter.

A battery will die eventually, you'll just have to take it
out and take voltage readings or replace it. A battery is
only a couple dollars.

If it uses the coin cell lithium battery, it'll cost around $5 and can
typically be found at many retail stores (Target, Best Buy, Radio Shack,
Walmart, etc.). They have a life expectancy of 5 years although they've
might've been in storage for year or two so figure on 3 years before you
need to start thinking about replacing it again.
