Clearing CMOS and Passwords
The computer's configuration (CMOS) may occasionally be corrupted. If it is, it is necessary to clear the CMOS memory
using switch SW1.
using switch SW1.
To clear and reset the configuration, perform the following procedure:
1.
1.
Prepare the computer for disassembly.
Ä
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
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 and keep it depressed for 5 seconds.
4.
Replace the access panel.
5.
Turn the computer on.
6.
Run Computer Setup (delete-utility) to reconfigure the system.
*When the CMOS button is pushed 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.

Setting the Supervisor and Power-On Passwords
A. Setting the Supervisor Password provides access protection for the Computer Setup utility.
1.
Turn off the computer, restart, then hold down the DEL key until the Computer Setup utility begins.
2.
Select “Set Supervisor Password,” press enter, and follow the screen instructions.
3.
The password will be enabled after saving settings and exiting the utility
B. Setting a Power-On Password.
NOTE: A Supervisor Password must have been previously set. That same password will be used for the Power-On
Password.
NOTE: A Supervisor Password must have been previously set. That same password will be used for the Power-On
Password.
1.
Turn on the computer, then hold down the DEL key until the Computer Setup utility begins.
2.
Select Advanced CMOS Setup--> Password Check.
3.
Select “Always” from the Available Options list.
4.
The password will be enabled after saving settings and exiting the utility.
NOTE: Clearing passwords clears both the Supervisor and Power-On Passwords, but does not clear the “Always”
option. To reset only the Supervisor Password, change “Always” to “Setup” on the available Options list.
