Passwords
As many as three passwords may be needed for any Lenovo computer: the
power-on password (POP), the hard disk password (HDP), and the supervisor
password.
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.
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):
+ User HDP - for the user
+ Master HDP - for the system administrator, who can use it to get access to
the hard disk drive even if the user has changed the user HDP
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 Lenov authorized service
technicians provide any services to reset either the user or the master HDP, or
to recover data from the hard disk drive. The hard disk drive can be replaced
for a scheduled fee.
Supervisor password
A supervisor password protects the system information stored in the BIOS. The
user must enter the supervisor password to get access to the BIOS and change
the system configuration.
Attention: If you forget the password, there is no service procedure to reset
the password. The system board must be replaced for a scheduled fee.
