disconnect all power cords from electrical outlets and disconnect all cables that are connected to the
computer.
2. Remove the computer cover. See Chapter 9 "Installing or replacing hardware" on page 89.
3. Locate the Clear CMOS /Recovery jumper on the system board. See "Hardware locations" on page 27.
4. Remove any parts and cables that impede your 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).
