Steps for Clearing BIOS Password Check 0
If users set BIOS Passwords (Supervisor Password and/or User Password) for a security
reason, BIOS will ask the password during systems POST or when system enters the BIOS
Setup menu. If it is necessary to bypass the password check, short the HW Gap to clear the
password by performing the following steps:
1. Remove power from the system.
2. Remove HDD, AC and Battery.
3. Disconnect the RTC Battery (Figure 5-1 Item10).
4. Locate the RTCRST# jumper (Figure 5-3).
5. Use an electric conductivity tool to short the two points of the RTCRST# jumper.
6. Plug in AC, keeping the RTCRST# jumper shorted.
7. Press Power Button until BIOS POST is finished, then remove the conductivity tool from
the RTCRST# 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.
