Passwords

As many as three passwords may be needed for any Lenovo 3000 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:

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:

A hard-disk password (HDP) protects the information stored on the hard disk

drive from being got access by an unauthorized person.

Attention: If the HDP has been forgotten, neither Lenovo nor Lenovo authorized

servicers provide any services to reset the 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 (SVP) protects the system information stored in the BIOS

Utility. The user must enter the SVP in order to get access to the BIOS Utility and

change the system configuration.
