system is plugged into an active AC outlet. In some systems the cooling fan is on even when the
computer is in the “Standby,” or “Suspend” modes. The power cord should always be disconnected
before servicing a unit.
5. Disconnect the power cord from the electrical outlet and then from the computer.
