Battery change on ASUS Board P5GD2

Hello,

I got last weeks for 3 times during the start up procedure an error about
"overclocking...". At the same time I noticed some modified settings in the
BIOS caused by the error. Investigastions in internet told me, this would
be a typical ASUS-board failure, caused mainly by the battery. Ok., I will
buy a new one, but how to change it?

If I change the battery while the PC is in shut down, do I loose all
settings in the BIOS, modified by myself? Or should I change the battery
during running PC? I could believe to store all modification in the last
case, because the voltage for BIOS will be not interrupted. Is this right?

Or is there a possibility to store (backup) the actuel BIOS-settings and
reload them later when the battery has been changed?

Thank you for informations and greetings

Klaus

Hello,

Well, will I loose my personal BIOS-settings by this procedure?

Regards

Klaus

I would verify the battery voltage, before buying another one.
Here, it would cost about $5 for a new battery. A battery that
measures 3.0V is still in good shape. A battery that measures
2.4V or lower, should be replaced. To measure the voltage,
one probe of your multimeter, touches the shiny top (+)
of the battery in it socket, while the other probe touches
some shiny metal at ground potential on the chassis. It is
relatively easy to get a measurement, because the battery
is a pretty big target for your multimeter probe.

Rather than the battery being at fault, the problem could be
with something else. Anything which causes the processor to
crash, can result in the BIOS recognizing that has happened,
and resetting certain settings. On my other computer, it means
a disk controller I disabled, gets re-enabled again. So
settings unrelated to processor stability, can be reset
in the BIOS.

The cause does not have to be overclocking. The processor
can be running at the normal speed, crash for some reason,
and the BIOS will conclude "crash due to overclock". The
BIOS settings will still be reset, even though the user
has not overclocked. So overclocking is not the only
reason for this to happen - virtually any piece of hardware
in the computer, which could cause the computer to crash,
could produce the same symptoms.

When you remove the battery, on some motherboards, there is
enough residual charge left in the +3VSB, to keep the settings
for a short time. There are posters to these newsgroups, who
claim to have changed a battery without losing the settings.
But I would not rely on that fact, and would write the
settings down on a piece of paper. Or take pictures of the
BIOS screens with a digital camera.

There are some motherboards, where you can store a "profile"
in the BIOS, and that allows restoring the settings later.
Very few motherboards have that feature.

thank you for the recommendations! I know how to measure voltage, this was
part of my profession ;-)

I didn't know, that such events could appear and was astonished to see the
changes in BIOS.

BIOS settings will still be reset, even though the user
has not overclocked.

So in my case.

That is not beautiful to hear. I hope, you are not wright and the trouble
is caused by the battery ;-)

Exact this I am looking for ;-) But ASUS seems not to be such a supplier.

Have a nice start in the new week,
