Thinpad R31 Bios password woes

By Johnrd1 ·
I've bought a secondhand R31 Laptop but the bios is locked - it requires the administrators password.

I need some form of backdoor password or advice on how to get it working!

does it have a floppy drive, and can you boot from it?

if yes then killcmos will usually wipe bios password protection right out.

everything, including bios updates is gone, right back to brand new factory settings.

dos boot disk required to use it.
also it does get reported by some antivirus apps as a trojan. [ because it writes to the cmos they think it's dangerous. ]

you have to explicitly run it after booting to dos.

If you do not have a floppy to boot from remove the battery and mains adapter and then there is another battery in the NB that provides power to the BIOS Chip if you disconnect this it will clear the BIOS and you'll be able to proceed from there but you'll need to reset everything in BIOS before you can run the NB properly.

If you download the user manual for this unit it will tell you where the battery is and if there is a jumper on the M'Board that allows you to clear the BIOS. If there is a jumper use this as it is faster and more reliable to clear the BIOS.

The following URL has the information that you require.

As there are several different models of the R31 you'll have to find the correct manual or listing for your NB
