Steps for Clearing BIOS Password Check

If users set the BIOS password (Supervisor password and/or User password) for a security reason, BIOS will ask the password during system POST or when the system enters the BIOS Setup Utility. To bypass the password check, users need to short the hardware gap to clear the password.

To clear the BIOS password:

1 Disconnect the power adapter and remove the battery from the notebook.

2 Turn off the notebook and remove hard disk drive. <Athena: both har dNves?>

For more information, see "Replacing the primary hard drive" on page 64 and "Replacing the secondary hard drive" on page 73.

Open the <Athena: which cover?> cover of the machine.

Locate the hardware gap. <Athena: can you help me find it on the system board? Richard: Need to shoot new pic once we know where the gap is.>

Use the blade of a flat screwdriver to short the two points of the gap.

6 Plug in the power adapter while keeping the screwdriver on the gap, and press the power button to turn on the notebook.

7 After the BIOS POST has finished, remove the tool from the gap.

8 Restart the notebook. Press the F2 key to enter the BIOS Setup Utility.

If are not prompted for a password, then the BIOS passwords have been cleared.

If you are prompted for a password, repeat the procedure.

Note: This procedure only clears the BIOS password (Supervisor password and User password). It does not clear a hard drive password.

9 Reassemble the notebook.
