I have been informed by another tech that there is a battery on the motherboard near the keyboard connector and that the best way to fix this is to cut the old battery off and solder a new battery to the pins of the old battery connections on the motherboard . Is this possible as I was looking at a Pentium 100 motherboard that did not have a battery in this location but did have writing with the words battery in this location

If you have a battery near the keyboard that is going bad, the best way is to desolder it and solder a new one on. Second best is to solder the pins as described. Third best is to put wires in place of the pins when you desolder the old one and connect with wire caps. Last best is to solder wires to the existing pins and wire cap the new battery on.
The choice is yours to make based on your competence. If you don't use a soldering iron much and don't have a low wattage iron then you should stay away from the steps where you remove anything from the board.
Finding batteries that fit existing M/Bs can be an experience. That's why there are at least 4 variations.
And there is the possibility that the board manufacturer put header pins near the battery so you can pull a jumper and install a external battery connector to the pins.
Replacing a board mounted battery also requires the M/B to be removed to do a halfway decent job. So it isn't a 30 second job. Ed Fair

Thanks Ed, I have a soldering iron and I'm getting a battery holder for aa size batteries alkaline . I probably will take the p.c away and fix it as it is at the users home and it will take some time to pull apart and re-assemble. .
