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 5.21, “System

Board,” for more information on replacing the system board.

Before replacing the system board, perform the steps below to be sure that stringent security has been properly enabled.

Enabling stringent security provides enhanced prtotection 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).

2. Remove the real-time clock (RTC) battery (refer to

Section 5.23, “RTC Battery,” for more information on

removing and replacing the RTC battery).

3. Wait approximately 5 minutes.

4. Replace the RTC battery and reassemble the computer.

5. Connect AC power to the computer. Do not reinsert any battery packs at this time.

6. Turn on the computer.

All passwords and all CMOS settings have been cleared.

CAUTION: To properly ventilate the computer, allow at least a 7.6-cm

(3-inch) clearance on the left and right sides of the computer.

The computer uses an electric fan for ventilation. The fan is controlled by a temperature sensor and is designed to turn on automatically when high temperature conditions exist. These conditions are affected by high external temperatures, system power consumption, power management/battery conservation configurations, battery fast charging, and software. Exhaust air is displaced through the ventilation grill located on the left side of the computer.
