Clearing CMOS*
The computer's configuration (CMOS) may occasionally be corrupted. If it is, it is necessary to clear the CMOS
memory using JBAT1 by performing the following procedure:
1. Prepare the computer for disassembly.
ÄCAUTION: The power cord must be disconnected from the power source before changing the jumper
setting. (NOTE: All LEDs on the board should be OFF). Failure to do so may damage the system board
2. Remove the access panel.
3. Remove the JBAT_1 jumper from pins 1 and 2 and place it on pins 2 and 3. Keep the jumper there for 5 seconds.
4. Replace the jumper on pins 1 and 2.
5. Replace the access panel.
6. Turn the computer on and run F10 Computer Setup (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.
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 JPWD.
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 F10 Computer Setup (Setup utility) instructions to establish new passwords.
* 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.
Installing the Fan Jumper Cable
Ensure that the fan jumper cable is properly installed before installing the access panel and starting the computer.
1. Connect the two-wire connector to S_FAN1 1.
2. Connect the three-wire connector to C_FAN1 2
3. Connect the central connector to the connector coming from the power supply 3.
