Recovering from a POST/BIOS update failure

If the power to your computer is interrupted while the POST and BIOS is being updated, your computer
might not restart correctly. If this happens, perform the following procedure to recover from the POST and
BIOS update failure. This procedure is commonly called Boot-block Recovery.
1. Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect
all power cords from electrical outlets and disconnect all cables that are connected to the computer.
2. Remove the computer cover. See "Removing the computer cover" on page 30.
3. Locate the Clear CMOS /Recovery jumper on the system board. See "Locating parts on the system
board" on page 11.
4. Remove any cables that impede access to the Clear CMOS /Recovery jumper.
5. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and
pin 3).
6. Reconnect any cables that were disconnected and reinstall the PCI card if removed.
7. Reinstall the computer cover and reconnect the power cords for the computer and monitor to electrical
outlets. See "Completing the parts replacement" on page 55.
8. Turn on the computer and then insert the POST and BIOS update (flash update) disc into the optical
drive. Wait a few minutes. Then, the recovery session begins. The recovery session will take two to
three minutes. During this time, a warning message will be displayed and no action is needed from you.
9. After the recovery session is completed, there will be no video, and your computer will automatically
turn off.
10. Repeat step 1 through step 4.
