Clearing CMOS

The computer's configuration (CMOS) may occasionally be corrupted. If it is, it is necessary to clear the CMOS memory using switch SW50. To clear and reset the configuration, perform the following procedure:

1. Turn off the computer and any external devices, and disconnect the power cord from the power outlet.

CAUTION: The power cord must be disconnected from the power source before pushing the Clear CMOS

Button (NOTE: All LEDs on the board should be OFF). Failure to do so may damage the system board.

2. Remove the access panel.

3. Press the CMOS button located on the system board.

4. Replace the access panel.

5. Turn the computer on and run Computer Setup (F10 Setup Utility) to reconfigure the system.

Disabling or Clearing the Power-On and Setup Passwords

1. Turn off the computer and any external devices, and disconnect the power cord from the power outlet.

2. Remove the access panel.

3. Locate the header and jumper labeled E49.

4. Remove the jumper from pins 1 and 2. Place the jumper over pin 2 only, in order to avoid losing it.

5. Replace the access panel.

6. Plug in the computer and turn on power. Allow the operating system to start. NOTE: Placing the jumper on pin 2 clears the current passwords and disables the password features.

7. To re-enable the password features, repeat steps 1-3, then replace the jumper on pins 1 and 2.

8. Repeat steps 5-6, then establish new passwords. Refer to the Desktop Management Guide and the Computer Setup (F10) Utility Guide for instructions on establishing new passwords.
