Passwords
As many as three passwords may be needed for any ThinkPad Notebook: 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.
Note:
If only an SVP is installed, the password prompt does not appear when the operating system is booted.
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. For how to remove the POP, see
“How to remove the power-on password” on page 39.
Hard-disk password
There are two hard-disk passwords (HDPs):
User HDP—for the user
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; the system administrator enters both in the same operation. The system administrator then
provides the user HDP to the system user.
Attention:
If the user HDP has been forgotten, check whether a master HDP has been set. If it has, it can be
used for access to the hard disk drive. If no master HDP is available, neither Lenovo nor Lenovo authorized
service technicians provide any services to reset either the user or the master HDP, or to recover data from
