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.
Ä
CAUTION:
You must disconnect the power cord 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 F10 Computer Setup (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 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
