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:

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; 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 servicers 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 (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.

Attention: If the SVP has been forgotten and cannot be made available to the

servicer, there is no service procedure to reset the password. The system board

must be replaced for a scheduled fee.

How to remove the power-on password

To remove a POP that you have forgotten, do the following:

(A) If no SVP has been set:

1. Turn off the computer.

2. Remove the battery pack.

For how to remove the battery pack, see “1010 Battery pack” on page 46.

3. Remove the DIMM slot cover.

For how to remove the DIMM slot cover, see “1070 DIMM slot cover” on page

51.

4. Remove the DIMM.
