Reset IBM ThinkPad BIOS Password
An IBM ThinkPad laptop can have three hardware password sets:
- Power-On Password
- Hard Disk Password
- Supervisor Password
Power-On Password
RT/CMOS RAM has 8 bytes reserved for the power-on password and the check character. The 8 bytes are initialized to hex 00. The microprocessor can access these bytes only during POST. After POST is completed, if a power-on password is installed, the password bytes are locked and no program can access them.
During power-on password installation, the password (1 to 7 characters) is stored in the security space.
Installing the password is a function of the built-in system program Easy-Setup. The power-on password does not appear on the screen when it is installed, changed, or removed. After the power-on password has been installed, it can be changed or removed only during POST.
Hard Disk Password
The hard-disk password (HDP) prevents unauthorized persons from accessing the data on the removable hard disk drive.
Supervisor Password
The supervisor password prevents unauthorized persons from changing the system information in Easy-Setup.
