Connecting the AC adapter
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. It is possible to receive an
electric shock from a system that is not properly grounded.
To connect the computer to external AC power:
1. Plug the AC adapter into the power connector on the computer (1).
2. Plug the power cord into the AC adapter (2).
3. Plug the other end of the power cord into an AC outlet (3).
