Clearing Configuration

The computer's configuration (CMOS) may occasionally be corrupted. If it does, it is necessary to
clear the CMOS memory.
To clear and reset the configuration, perform the following procedure:
1. Prepare the computer for disassembly (Section 5.4).
CAUTION: The power cord must be disconnected from the power source before changing the jumpers.
Failure to do so may damage the system board.
2. Remove the system unit cover (Section 5.7).
3. Remove the E50 jumper from pins 1 and 2 for 60 seconds; then, replace the jumper.
4. Replace the system cover.
5. Turn the computer on.
6. Run the Computer Setup utility to reconfigure the system.
When the jumper is removed, both the power-on password and the setup password become invalid
because both are stored in the configuration memory. You will need to reset the passwords.
