CAUTION: Before you begin any of the procedures in this section,
follow the safety instructions on page 7.
NOTICE: To avoid damaging the system board, disconnect the power cable
from the electrical outlet and from the back of the computer, and then press
the power button before you open the computer cover. The system board
continues to receive a small amount of power when the computer is turned off
and attached to an electrical outlet (the system-board power light [see
page 66] is on when power is detected).
1 Turn off the computer and attached devices, and disconnect them
from their electrical outlets.
NOTICE: To disconnect a network cable, first unplug the cable from your
computer and then unplug it from the network jack on the wall.
2 Briefly press the power button.
Pressing the power button when the computer is not connected to an
electrical outlet discharges residual electricity and can help prevent
system board damage.
