D
isabling a Forgotten Password
If you forget your system or setup password, you cannot
operate your system or change settings in the System
Setup program until you remove the computer cover,
change the password jumper setting to disable the pass-
words, and erase the existing passwords.
To disable a forgotten password, perform the following
steps:
1. Remove the computer cover according to the
instructions in “Removing the Computer Cover”
in Chapter 5.
2. Remove the jumper plug from the PSWD jumper
to disable the password feature.
Refer to “Jumpers” in Chapter 5 for jumper informa-
tion and to Figure 5-7 for the location of the
password jumper (labeled “PSWD”) on the system
board.
3. Replace the computer cover.
4. Reconnect your computer and peripherals to
their power sources, and turn them on.
Booting your system with the PSWD jumper plug
removed erases the existing password(s). To assign a
new system and/or setup password, continue to
step 5.
NOTE: Before you assign a new system and/or setup
password, you must replace the PSWD jumper plug.
5. Repeat step 1.
6. Replace the PSWD jumper plug to reenable the
password feature.
7. Replace the computer cover, reconnect the com-
puter and peripherals to their power sources, and
turn them on.
Booting the system with the PSWD jumper installed
reenables the password feature. When you enter the
System Setup program, both password categories
appear as
NOT ENABLED
, meaning that the password
feature is enabled but that no password has been
assigned.
8. Assign a new system and/or setup password.
To assign a new system password, see “Assigning a
System Password” found earlier in this chapter. To
assign a new setup password, see “Assigning a Setup
Password” found earlier in this chapter.

static Discharge” in the safety instructions at
