Password Pads

When the power-on password (POP), hard disk password (HDP), and supervisor password (PAP) are used, the following situations may occur:

The ThinkPad computer with the bay can support more than two HDPs.

Supervisor and Hard Disk Passwords:

The supervisor password (PAP) and the hard disk password (HDP) are security features that are used to protect the system and the hard disk data from unauthorized access.
No overriding capability is provided. If only a hard disk password is set, you must obtain permission from the password owner to unlock the password before running diagnostic tests and performing service.
If both a supervisor password and a hard disk password are set, you can enter IBM BIOS Setup Utility by pressing the Enter key or by entering the power-on password at the supervisor password prompt. In this case, you can not select some items in the IBM BIOS Setup Utility.

The supervisor password and hard disk password cannot be replaced if they are forgotten.
If the customer forgets the supervisor password, the system board must be replaced.
