Clearing Password Check

Hardware Open Gap Description is as follows:

Aspire 4710 Bios Reset Jumper

If users set a BIOS Password (Supervisor Password and/or User Password) for security reasons, the BIOS will prompt for a password during system POST or when the system enters the BIOS Setup menu. If it becomes necessary to bypass the password check, users need to short the HW Gap to reset the password by performing the following procedure:

  1. Power off the system and unplug the AC and Battery from the machine.
  2. Open the Hard Drive and RAM doors.
  3. Remove the Hard drive.
  4. Remove the mylar as shown in the above figure.
  5. Find the appropriate HW Gap on M/B as shown in the picture.
  • G1 is the RTC Reset. When asserted, this signal resets register bits in the RTC well. Unless the CMOS is being cleared (only to be done in the G1 power state), the RTCRST# input must always be high when all other RTC power planes are on. In the case where the RTC Battery is dead or missing on the platform, the RTCRST# pin must rise before the RSMRST# pin.
  • G2 is the Secondary RTC Reset. This signal resets the manageability register bits in the RTC well when the TRTC battery is removed. The SRTCRST# input must always be high when all other RTC power planes are on. In the case where the RTC Battery is dead or missing on the platform, the SRTCRST# pin must rise before the RSMRST# pin.
  1. Use an electric conductivity tool to short the two points of the HW Gap (G1).
  2. Plug in AC, keeping the HW Gap shorted, and press Power Button to power on the system till BIOS POST is finished. Once BIOS POST has run, remove the tool from the HW Gap.
  3. Restart the system. Press the F2 key to enter BIOS Setup menu.

If there is no Password request, the BIOS Password has been successfully cleared. Otherwise, follow the steps and try again.
