22925 2001-10-29 07:54:00 Before I do, how do I replace the battery, is it straight forward take it out take to watch shop.
When starting up it forgets everything like time etc. Sometimes checksum error but after that reset will start ok.

Fairly old pc.
Cheers

22926 2001-10-29 08:19:00 If it's a round battery of about 20mm diameter, it's fairly straightforward to take out and replace. Access may be awkward and to prevent damage to the battery holder make sure that cables are out of the way and you can get to it. The design of the holder varies a bit, but you will see a spring clip holding the battery down, and at the end of that the holder may have a bit of springy plastic you can push down to allow the battery to slide out.

The cheapest replacement can be bought from The Warehouse for about $4.95, the number is CR2032.

If the battery is soldered on the board, its a different ball game, in that case respond to this posting and the details can be given to replace it.

22928 2001-10-29 09:57:00 OK, fine. replace the CR2032 battery, but does one loose the bios settings ? Guest (0)
22929 2001-10-29 10:24:00 When I changed the battery in my old machine, I wrote down my BIOS settings prior to the operation, but surprise surprise, they kindly stayed intact while under anaesthetic.

I kept the machine plugged in, but switched off -- maybe that's why?

Don't forget the anti-static wrist strap.

It explains a lot about the battery, timekeeping, and CMOS reliance on battery, plus precautions to take when changing battery etc.
It is well worth a visit.

Cheers everyone.
