4.

Disconnect the power cord from the power outlet and disconnect any external devices.

CAUTION

Regardless of the power-on state, voltage is always present on the system

board as long as the system is plugged into an active AC outlet. You must disconnect the
power cord to avoid damage to the internal components of the computer.
