Clearing CMOS and Passwords
Passwords may need to be changed, or the computer’s configuration (CMOS) may occasionally be
corrupted. Both can be cleared using jumper JP5.
1. Turn off the computer and any external devices, then disconnect the power cord from the
power outlet.
2. Remove the access panel on the left side of the computer.
3. Locate the header labeled JP5. Place a jumper across pins 1 & 2 on JP5.
4. Connect the power cord to the power outlet.
5. Turn on the computer.
6. The password reset screen automatically displays. Choose either :
F1 to reset CMOS
F4 to reset passwords
The computer executes the choice and automatically shuts down.
7. Disconnect the power cord from the power outlet.
8. Remove the jumper from JP5 pins 1 & 2 and place it on pins 2 & 3 (safe position).
9. Replace the access panel.
10. Reconnect the power cord to the power outlet and turn the computer on.
If F1 was selected in step 6, the CMOS defaults are reset when the computer starts.
If F4 was selected, all passwords are cleared when the computer starts.
NOTE: Clearing CMOS clears the Power-On Password. It does NOT clear the Supervisor Password.
Setting the Supervisor and Power-On Passwords
A. Setting the Supervisor Password provides access protection for the Computer Setup utility.
1. Turn on the computer, then hold down the DEL ey until the Computer Setup utility begins.
2. Select “Change Supervisor Password” and follow 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 previously been set. That same password will be used for
the Power-On Password.
1. Turn on the computer, then hold down the DEL ey until the Computer Setup utility begins.
2. Select Advanced CMOS Setup➔Password Chec .
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.
NOTE: Clearing CMOS clears the Power-On Password. It does NOT clear the Supervisor Password.
