Having problems with your IBM ThinkPad R40 2681 ?

Bios battery location

\015 My bios battery need to be replaced. I need to know IBM R40 bios battery location.\015

Answers :

On the R40, you will need to remove two things to get to the BIOS battery: 1) the regular battery, 2) the Keyboard. The BIOS battery is located just underneath the keyboard. In order to remove the keyboard you have to remove two screws from the bottom of the notebook (each will have a little picture of a keyboard and arrow next to it). Pop the keyboard up gently and the BIOS battery is just above the mouse buttons.

Check out the service manual for more details (pages 68, 77, 85).
