    Clearing Password Check and BIOS Recovery
    This section provide you the standard operating procedures of clearing password and BIOS recovery for 
    Aspire 4935/4935G. Aspire 4935/4935G provides one Hardware Open Gap on main board for clearing 
    password check, and one Hotkey for enabling BIOS Recovery.
    Clearing Password Check
    Hardware Open Gap Description
    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:
    •Power Off a system, and remove HDD, AC and Battery from the machine.
    •Open the back cover of the machine, and find out the HW Gap on M/B as picture.
    •Use an electric conductivity tool to short the two points of the HW Gap.
    •Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the 
    system till BIOS POST finish. Then remove the tool from the HW Gap.
    •Restart system. Press F2 key to enter BIOS Setup menu.
    •If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and 
    try again.
    NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).

    BIOS Recovery by Crisis Disk
    BIOS Recovery Boot Block:
    BIOS Recovery Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS 
    initialization. Users can enable this feature to restore the BIOS firmware to a successful one once the previous 
    BIOS flashing process failed.
    BIOS Recovery Hotkey:
    The system provides a function hotkey: Fn+Esc, for enable BIOS Recovery process when system is powered 
    on during BIOS POST. To use this function, it is strongly recommended to have the AC adapter and Battery 
    present. If this function is enabled, the system will force the BIOS to enter a special BIOS block, called Boot 
    Block.
    Steps for BIOS Recovery by Crisis Disk:
    Before doing this, one Crisis Disk should be prepared ready in hand. The Crisis Disk could be made by 
    executing the Crisis Disk program in another system with Windows XP OS.
    Follow the steps below:
    1.Power Off failed system.
    2.Attach a USB floppy drive to the failed system. 
    3.Insert the Crisis Disk in to the USB floppy drive attached to the BIOS flash failed system.
    4.In the power-off state, press and hold Fn+Esc then press the Power button. 
    The system powers on and the Crisis BIOS Recovery process begins.
    BIOS Boot Block begins restoring the BIOS code from the Crisis floppy disk to BIOS ROM on the failed 
    systems.
    When the Crisis flash process is finished, the system restarts with a workable BIOS. 
    5.Update to the latest version BIOS for the system using the regular BIOS flashing process.
