Clearing Configuration
The computer's configuration (CMOS) may occasionally be corrupted. When 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 by following the procedures specified in Section 5.3.
2. Remove the hood or access panel (see Section 5.6).
3. Remove the E8 jumper from pins 1 and 2 for 60 seconds; then replace the jumper.
4. Replace the cover and tighten the thumbscrews on the rear panel.
5. Turn the computer on.
6. Run the Computer Setup utility to reconfigure the system.
When jumper E8 is removed, the password becomes invalid because the password is stored in the
configuration memory. You will need to reset the password.
6.2.4
Changing the Real-Time Clock (RTC) Battery
When installing the replacement RTC Battery, the battery connector is keyed and should be connected
to the pins on the E9 battery header connector.
Refer to Chapter 5 for complete instructions on installing a replacement RTC battery.
