I bought an IBM A31 Thinkpad Laptop with a BIOS supervisor password. I cleared the CMOS battery for a couple of hours but nothing changed. My research has revealed however that the only way to clear the password would entail reading off the security chip through another PC interface with some hardware connection which requires some soldering jobs. I found a site that has the diagram for it before signing up with EE in the hope that I would find another way to do it. Do you have another solution other than the soldering option offered by the Sodoityourself site?
