Remove the Thinkpad main battery. Look for a small yellow disk. This is the CMOS battery. It is connected to the motherboard with two (2) wires that plug into the motherboard. The plug is included on the wires of a new battery. Check EBay for Thinkpad CMOS batteries. I have also heard Radio Shack in some cases carries this battery.

Hey Wiz,
Do you have pics of where this cmos battery
is located on the motherboard? That's the help
I need. I haven't found it yet. Pics of its location
would be most helpful.
