Product Description
1.2 Resetting the Computer
If the computer you are servicing has an unknown password,
follow the steps below to reset the password. These steps also
clear CMOS.
✎The following steps will not clear an unknown password if the
stringent security option has been enabled in the BIOS. If
stringent security is enabled, the system board must be replaced
to reset an unknown password. Refer to Section 5.22, “RTC
Battery,” for more information on replacing the system board.
Before replacing the system board, perform the steps below to
make sure stringent security has been properly enabled.
Enabling stringent security provides enhanced protection for the
power-on password and administrator password and other forms
of power-on authorization. Stringent security is enabled/disabled
by accessing the Password Options menu in the Computer Setup
utility. Refer to Section 2.1, “Computer Setup,” for more
information.
1. Prepare the computer for disassembly (refer to Section 5.3,
“Preparing the Computer for Disassembly,” for more
information). Remove the real-time clock (RTC) battery
(refer to Section 5.22, “RTC Battery,” for more information
on removing and replacing the RTC battery).
2. Wait approximately 5 minutes.
3. Replace the RTC battery and reassemble the computer.
4. Connect AC power to the computer. Do not reinsert any
batteries at this time.
5. Turn on the computer.
All passwords and all CMOS settings have been cleared.
