Connecting AC power

WARNING! To reduce the risk of electric shock or damage to the equipment:

Plug the power cord into an AC outlet that is easily accessible at all times.

Disconnect power from the computer by unplugging the power cord from the AC outlet (not by unplugging the power cord from the computer).

If provided with a 3-pin attachment plug on the power cord, plug the cord into a grounded (earthed) 3- pin outlet. Do not disable the power cord grounding pin, for example, by attaching a 2-pin adapter. The grounding pin is an important safety feature.

NOTE: Refer to the illustration that most closely matches your computer.

To connect the computer to external AC power:

1.Plug the adapter into the power connector (1) on the computer.

2.Plug the power cord into the adapter (2).

3.Plug the other end of the power cord into an AC outlet (3).
