Passwords

As many as three passwords may be set for any ThinkPad
computer: the power-on password (POP), the hard disk
password (HDP), and the supervisor password (SVP).
When the power-on password, the hard disk password, or
the supervisor password 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. The password must be entered
before an operating system can be booted.
Hard disk password: There are two hard-disk passwords
(HDPs):
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. The Master + User mode requires
two HDPs and is designed for the system
administrator to input both in the same operation.
The system administrator then provides the user
HDP to the system user.
