NOTE:
The following procedure is only for clearing BIOS Password (Supervisor Password and
User Password).

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. Remove power from the system.
2. Remove HDD, AC and Battery.
3. Disconnect the RTC Battery
4. Locate the R582 jumper.
5. Use an electric conductivity tool to short the two points of the R582 jumper.
6. Plug in AC, keeping the R582 jumper shorted.
7. Press Power Button until BIOS POST is finished, then remove the conductivity tool from
the R582 jumper.
8. Restart the system. Press F2 to enter BIOS Setup menu.
9. If there is no Password request, BIOS Password is cleared.
10. If a password is requested, repeat Steps 1 through 9.
