Disabling a Forgotten Password

The system's software security features include a system password and a setup password, which are

discussed in detail in

"Using the System Setup Program

" on page 29. The password jumper enables these

password features or disables them and clears any password(s) currently in use.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the

components inside the system. Before performing any procedure, see your Product Information Guide for

complete information about safety precautions, working inside the computer and protecting against electrostatic

discharge.

1

Turn off the system and attached peripherals, and disconnect the system from the electrical outlet.

2

Open the system. See "Opening and Closing the System" on page 44.

3

Remove the password jumper plug.

See Figure 6-1 to locate the password jumper on the system board.

4

Close the system. See "Closing the System" on page 47.

5

Reconnect the system to the electrical outlet, and turn on the system.

The existing passwords are not disabled (erased) until the system boots with the password jumper plug

removed. However, before you assign a new system and/or setup password, you must install the jumper

plug.

NOTE: If you assign a new system and/or setup password with the jumper plug still removed, the system

disables the new password(s) the next time it boots.

6

Turn off the system, including any attached peripherals, and disconnect the system from the electrical

outlet.

7

Open the system.

8

Install the password jumper plug.

See Figure 6-1 to locate the password jumper on the system board.

9

Close the system, reconnect the system to the electrical outlet, and turn on the system.

10

Assign a new system and/or setup password.

To assign a new password using the System Setup program, see "Using the System Setup Program" on

page 29.
