Connecting a Power Source
You can use either an AC adapter or a rechargeable battery pack as a power source for your computer.
Using the AC Adapter
✍
Use your computer only with the supplied AC adapter.
To use the AC adapter
1 Plug one end of the power cord (1) into the AC adapter (3).
2 Plug the other end of the power cord into an AC outlet (2).
3 Plug the cable connected to the AC adapter (3) into the DC IN port (4) on the computer or on the port replicator.
!
The shape of the DC In plug varies depending on the AC adapter.
✍
To disconnect your computer completely from AC power, unplug the AC adapter.
Make sure that the AC outlet is easily accessible.
If you do not intend to use your computer for a long period of time, place the computer into Hibernate mode. See Using Hibernate Mode (page 118) .
This power saving mode saves the time of shutting down and resuming.
