5.3 Resetting CMOS
The computer's configuration (CMOS) may occasionally be corrupted. If it is, it is necessary to
clear the CMOS memory using the CMOS button on the system board. To clear and reset the
configuration, perform the following procedure:
1. Prepare the computer for disassembly.
2. Disconnect the power cord from the power outlet.
3. Remove the access panel.
Å WARNING: The power cord must be disconnected from the power source before removing the access
panel. Stray voltage on the system board may injure you.
4. Press the CMOS button located on the system board and keep it depressed for 5 seconds.
5. Replace the access panel.
6. Reconnect the power cord.
7. Turn the computer on.
8. Run the Computer Setup (F10) utility to reconfigure the system.
✎
When the CMOS button is pushed the password becomes invalid because it is stored
in the configuration memory. You will need to reset the password.
Ä CAUTION: The power cord must be disconnected from the power source before pushing the CMOS
Button. Failure to do so may damage the system board.
