Is the CMOS battery changable by user on an approximately 166 MHz
Packard Bell PC or is it soldered into the motherboard?
Am I looking for a disk battery or what is the shape I am looking for?
At startup, neighbors PC sends message
"CMOS battery is dead, PLEASE enter date and time".

Thanks for help.

hi.. if the owner could locate the documentation for the PC, it might
contain info about what type of battery is used with that motherboard.

If not, you might see the coin-type battery.. about the size of a US
quarter.. shiny, mounted in a holder that you should be able to easily
remove it from.

A 166MHz system most likely wouldn't have a battery that's soldered to the
motherboard, but then ya never know with manufacturers like P-B.

There could also be a different type. Here again, the documentation would
help you locate it. Some batteries for the CMOS/clock are inside an
integrated circuit. The system manual might indicate where this IC is
located.. it's generally referred to as a RTC, or Real Time Clock chip.

Before you pull it out (either type), you should do a couple of preliminary
things first. Get into the machine's CMOS settings, and write down all of
the present settings.
Also.. before you pull the chip out to take it with you on a quest for a
replacement, you should instead get the device numbers from the RTC and see
if you can find a replacement first. One of many suppliers of such chips is
Jameco Electronics.

http://www.jameco.com

If you're unsure about extracting & installing the chip, or unfamiliar with
CMOS settings, you might be better off taking the machine to a service
shop.

Oh, i almost forgot.. the date is 8-2-99 and the time here is 4:38 PM, heh.

cheers

Perhaps I'm missing something, but why can't a soldered-in battery be
replaced?

It can. but it's not likely to be soldered in.
You have probably already lost the settings anyway, but write down what is
there.

If the OS is running DEFINATELY write down all the HD settings, like the LBA
modes, everything in the submenu for the HD ! If you have a CDROM, see if it's
connected to the soundcard or the MB.

If it doesnt run, like it says "missing operating system or something, write
down every number you can find on the HD while you have it apart !

I don't know specifically about your model, but I have seen computers
with a disk/coin battery soldered to the motherboard. Unless it was
a really really cheap model, there is usually a 4-pin connector
*somewhere* on the motherboard for an "external" battery...the kind
that looks like a small plastic box with wires and a connector coming
out of it. There is also usually a jumper to select the soldered-in
or the external battery. You might inspect the motherboard for
a connector like this...usually 4 pins in a row, possibly with one
missing, labeled "BATTERY" or "EXT BAT" or "CMOS BAT" or similar.

Make sure you find out from Packard Bell or other documentation what
voltage battery to use! Also, the comments by others about writing
down your CMOS settings, if the computer is working now.

Good luck!

It can, if you can find an equivalent battery with solder tabs and/or
a holder that will fit the holes. Oh yeah, you also have to be able
to solder on a 4+ layer computer motherboard without messing it up.

In other words: Somebody that works as a professional electronics
tech could probably do it. For anybody else, it's probably better
to consider the soldered in battery as "not replacable". Besides,
except on really cheap junk, motherboards with soldered batteries
have a connector for an external battery.

Just my opinion.

Yes you can replace the soldered in battery, you will have to replace it with
the same type, voltage and capacity of the one that is in there now. You can
remove it and take it to one of the battery supply houses, or as someone has
said you can replace it with an external battery. If you do, remove the old
battery so that it doesn't leak all over your motherboard. The location of
the battery jumper is in the motherboard manual.>Is the CMOS battery changable

Most likely it has a 3-button stack or "cylinder battery", 3.6v 50mah.
They are easy to remove by rocking it back and forth until it breaks loose from the motherboard. Generally these do not have a plug for external battery, but there may be a few exceptions. The jumper near the battery is a cmos reset and not a battery connector.

You will need to solder to reattach the new battery, so if you havn't done that a lot, you might ask someone who has to do it for you.
Easiest replacement method is to us a "Button Coin Cell Battery Holder Case"(ebay) and a CR2032 button battery, as that has leads and is easy to solder.

One of my 20th century computers kept its CMOS alive by three AA batteries in a holder that connected to the motherboard via a SIP header.

He's probably replaced the CMOS battery at least 3 more times now, since the OP was in 1999.

An old Packard Smell like that you would keep the battery and replace the computer.
