Clearing Password Check and BIOS Recovery
This section provide you the standard operating procedures of clearing password and BIOS recovery for
Aspire one. Aspire one 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
R219
Item Description
Clear CMOS Jumper
Location
3G bay, near the 3G connector
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 the system, and remove HDD, AC and Battery from the machine.
Open the back cover of the machine, and locate the HW Gap on M/B as shown above.
•
•
Use an electric conductivity tool to short the two points of the HW Gap.
Plug in AC power, 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 USB Flash Crisis Disk:
Before doing this, a Crisis Diskette should be prepared ready in hand. The Crisis Diskette could be made by executing the Crisis Disk program in another system with Windows XP OS.
Follow the steps below:
1.
Plug in the USB disk.
2.
Launch the wincris.exe program to create a USB Crisis Disk. Click Start to initiate the process.
3.
Select the Quick Format option to format the disk and click Start. Follow the instructions on the screen to create the disk.
4.
Copy the KAV60.fd BIOS file into USB flash disk root directory.
NOTE:
Do not place any other *.fd file in the USB flash disk root directory.
To use the Crisis USB key, do the following:
1.
Plug USB storage into USB port.
2.
Press Fn + ESC button then plug in AC power.
The Power button flashes orange once.
3.
Press Power button to initiate system CRISIS mode.
When CRISIS is complete, the system auto restarts with a workable BIOS.
4.
Update the latest version BIOS for this machine by regular BIOS flashing process.
