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.Power Off the system, and remove HDD, AC and Battery from the machine. 2.Disconnect the RTC Battery cable and locate the RTC_RST jumper. 3.Use an electric conductivity tool to short the two points of the HW Gap. 4.Plug in AC, keeping the HW Gap shorted. Press Power Button utill BIOS POST is finished, then remove the tool from the HW Gap. 5.Restart the system. Press F2 key to enter BIOS Setup menu. 6.If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and try again. NOTE: These steps are only for clearing BIOS Password (Supervisor Password and User Password).
