Clearing Password Check
Hardware Open Gap Description
Steps for Clearing BIOS Password Check
If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask
the password during systems POST or when systems enter to BIOS Setup menu. However, once it is
necessary to bypass the password check, users need to short the G1 jumper to clear the password.
To reset the Supervisor and User BIOS passwords, perform the following steps:
•
Power Off the system and remove the AC power and battery pack from the machine.
•
Open the back cover of the machine (DDR & Thermal)
•
Remove the CMOS battery form battery socket on M/B.
•
Use an electric conductivity tool to short the Short G1 jumper near CMOS battery.
•
Replace the CMOS battery, battery pack, and AC power and start the system.
•
Hit F2 to enter BIOS and check the passwords are clear.
NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).
