Passwords
As many as three passwords may be needed for any
ThinkPad computer: the power-on password (POP), the
hard-disk password (HDP), and the supervisor password
(SVP).
Exception: If only SVP is installed, the password prompt
doesn’t appear when the operating system is
booted.
When any of these passwords is used, a password prompt
appears on the screen whenever the computer is turned
on. The computer does not start until the password is
entered.
Power-on password:
A power-on password (POP) protects the system from
being powered on by an unauthorized person. Without
knowing the password, nobody can start the system.

v User HDP—for the user
v Master HDP—for the system administrator, who can use
it to get access to the hard disk even if the user has
changed the user HDP
Note: There are two modes for the HDP: User only and
Master + User. You can enter two HDPs when you
select Master + User.
Attention
If the master HDP has been forgotten, there is no
way to delete it. But you can still get access to the
hard disk if you remember the user HDP. If both
user HDP and master HDP have been forgotten, the
password cannot be removed and the hard disk will
not be accessible.
