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.

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

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

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