Clearing CMOS
The computer's configuration (CMOS) may occasionally be corrupted. If it does, it is necessary to clear the CMOS
memory using push button switch SW50.
To clear and reset the configuration, perform the following procedure:
1. Prepare the computer for disassembly.
ÄCAUTION: The power cord must be disconnected from the power source before pushing the Clear CMOS
Button. Failure to do so may damage the system board
2. Remove the access panel.
3. Press the CMOS button. Keep the button depressed for 5 seconds.
4. Replace the right access panel, then reconnect the power cable.
5. Turn the computer on.
6. Run F10 Computer Setup to reconfigure the system.
Pushing the CMOS button will reset CMOS values to factory defaults and will erase any customized information includ-
ing asset numbers and special settings.
Disabling or Clearing the Power-On 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 two access panels.
6. Plug in the computer and turn on power to all equipment. Allow the operating system to start. This 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 Computer Setup (F10 Setup) instructions to establish new passwords.
Setting the Setup and Power-On Passwords
