AC Adapter
The AC adapter performs two functions:
-
It powers the computer from an external AC source.
-
It charges the computer battery.
The adapter automatically detects the AC line voltage (110V or 220V) and adjusts
accordingly.
The following are recommended when using the AC adapter:
-
Use a properly grounded AC outlet.
-
Use one AC outlet exclusively for the computer. Having other appliances on the same
line may cause interference.
-
Use a power strip with built-in surge protection.
Connect the AC adapter:
-
Plug the AC cord to the adapter.
-
Plug the other end of the AC cord into the wall outlet. Make sure the green LED on the
adapter turns on.
-
Attach the DC plug into the power jack of the computer.
