Clearing Forgotten Passwords

CAUTION: Before you begin any of the procedures in this section, follow the

safety instructions on page 9.

If you forget your supervisor or setup password, you cannot operate your computer or

change settings in the system setup program until you clear the forgotten password(s).

1Shut down the computer through the Start menu (see page 30).

2Ensure that your computer and attached devices are turned off. If your computer and

attached devices did not automatically turn off when you shut down your computer,

turn them off now.

NOTICE: To disconnect a network cable, first unplug the cable from your computer and then

unplug it from the network wall jack.

3Disconnect any telephone or telecommunication lines from the computer.

4Disconnect your computer and all attached devices from their electrical outlets, and

then press the power button to ground the system board.

CAUTION: To guard against electrical shock, always unplug your computer from

the electrical outlet before opening the cover.

5Remove the computer cover (see page 71).

NOTICE: Before touching anything inside your computer, ground yourself by touching an

unpainted metal surface, such as the metal at the back of the computer. While you work,

periodically touch an unpainted metal surface to dissipate any static electricity that could harm

internal components.

6Locate the 2-pin password jumper (see page74) on the system board, and then attach

the jumper to both pins.

When you receive your computer, the jumper is attached to only one pin.

7Replace the computer cover (see page90).

8Connect your computer and devices to electrical outlets, and turn them on.
