- 1). Navigate to http://www.xs4all.nl/~matrix/mpwlist.html, which contains many master passwords for all types of BIOS. Master passwords are secret "backdoor" passwords that can get you into your BIOS even where it is locked. Navigate to the section of the page for IBM computers and try the passwords listed to see if they unlock your computer and reset the BIOS password.
- 2). Telephone IBM technical support or e-mail support through the company's webpage if Step 1 doesn't work. Tech support will likely have the most current master passwords for your model of Thinkpad if the ones listed above do not work.
- 3). Telephone a computer repair technician and request a BIOS chip removal or jumper reset if the previous steps don't work. Removing and replacing the BIOS chip on the computer can reset the password, but this should not be attempted by laymen, as laptops are notoriously difficult to disassemble and reassemble properly.
