Password Pads
When the power-on password (POP), hard disk password (HDP), and supervisor password (PAP) are used,
the following situations may occur:
- If the POP is the same as the HDP, the POP prompt appears, but the HDP prompt does not appear.
- If the POP is not the same as the HDP, both prompts appear.
- The PAP and the HDP:
If the PAP is used,the HDP is enabled automatically, and no HDP prompt appears.
The HDP is set the same as the PAP.
The ThinkPad computer with the bay can support more than two HDPs.
- If the POP is the same as one of the HDPs (HDP-1 or HDP-2), a POP prompt appears. But one of the
HDP prompts does not appear.
- If the POP is not the same as either of the HDPs (HDP-1 or HDP-2), both prompts appear.
- If the PAP is used, the HDP-1 or the HDP-2 is automatically enabled, and neither HDP prompt
appears. Both HDP-1 and HDP-2 are set the same as the PAP.
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.
-Attention-
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.
If the customer forgets the hard disk password, the hard disk drive must be replaced.
