Clearing Password Check and BIOS Recovery

This section provides you with the standard operating procedures of clearing password and BIOS recovery for 
the Aspire 5251/5551G/5551. The machine provides one Hardware Open Gap on main board for clearing 
password check, and one Hotkey for enabling BIOS Recovery.

Clearing Password Check

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 J1 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).
