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 HW Gap to clear the password by the
following steps:
1. Flash to BIOS v1.04 (or later version), and enter BIOS Setup Utility.
2. Set the Supervisor password, User Password, and power on password. Press F10, and save and exit.
After the Save, the notebook auto re-starts.
3. After power-on, the system prompts to input the password. Enter the password set in step 1 and allow the
device to startup.
4. Press and hold the power key to shutdown the system.
5. Open the memory door and remove the memory modules.
6. Remove the battery pack and AC adapter.
7. Short the R72 Pins shown above (ensure that the circuit is complete).
