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).
If any of these passwords has been set, a prompt for it
appears on the screen whenever the computer is turned
on. The computer does not start until the password is
entered.
Exception: If only an SVP is installed, the password
prompt does not appear when the operating
system is booted.

Power-on password:

Apower-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):
vUser HDP—for the user
vMaster 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; the system administrator enters both in
the same operation. The system administrator then
provides the user HDP to the system user.
