Battery Changing

S

Sharon F

I wasn't endorsing changing the battery with the computer on; just giving an
opinion that there wouldn't be any danger of personal injury due to
electrocution.

Don, the original question was about replacing the battery while the
machine was running. At my house, there is a difference between plugged in
and running...

I see you feel that even this isn't dangerous to a person (no coffee yet
this AM) so will amend my original statement to "possibly dangerous to your
person"

Still, there's enough risks in life - those chosen and those that find us -
that this is one I will continue to leave off my list of chosen risks.

I have just changed the CMOS battery on my system without losing any
of the bios settings.

It takes me in the region of 15-seconds to replace the battery, as
someone has already mentioned using a piece of tape (insulation type)
attached to the top of the battery is a great aid to removing the
battery.

The replacement battery which should be close to hand is then just
popped in! :)

I have no idea how long the bios information will remain whilst the
battery is actually removed from the system.

How long the information remains while the battery is out depends on the
computer and the condition of the battery. You usually have 15 minutes or
so, but it's sometimes much longer. I've seen it last as long as several
hours.

That is handy to know! I appear to be replacing my CMOS battery every
six months.

My system is not powered on 24/7 but is usually on for a 12-hour
period and then switched off for a period of 12-hours on a regular
basis.

No doubt leaving it switched on permanently would ensure that the CMOS
battery lasted for a longer length of time.

I thought that there might have been a problem with the motherboard
draining the battery but when I contacted the motherboard manufacturer
they reckoned that the way my system was being powered on/off
contributed to the battery replacement period.

Six months is a *very* short time. If the battery is failing that often,
you're either buying defective batteries or there's a motherboard problem
that's draining them. Normally batteries last at least three and often as
many as five or more years.

How long it's powered on shouldn't matter. My systems are about the same.
One of them has had its battery in it without a problem for 5-6 years.

Nope.

I very strongly doubt that. I think they just wanted to blame you rather
than themselves. Most home users don't run their machines 24/7, and probably
don't even keep them on as long as you do each day. And their batteries
typically last at least three years.

We power down all 30 of our PC's every night at 5 and start them again at 8
the next day. Most of our PC's are in service from 3 to 5 years. I've never
replaced a CMOS battery. I agree with Ken. Something else is causing your
problem.

Ken,

Is there any way of testing the battery with software? My battery has been
in my computer for least six years now. Hmmmm.... may be the time to tell
the Mrs that the computer needs replacing. :)

No, I don't think so. I would just wait until it fails.

Six years is a *long* time when it comes to computers.

Correct, he has a problem if his motherboard battery [usually a 3 volt
lithium cell battery, almost always a CR2032] needs replacing that often. If
I am correct, there is no battery usage while the computer is plugged into
an electrical outlet. That leak by current maintains the motherboard
settings while the computer is turned off. The lithium battery comes into
play when there is no other electrical current supplied (you unplug the
power cord) to the motherboard.
