AC Adapter
1. DC-out Connector
The DC-out connector docks to the power jack (DC-in) on the
computer.
2. LED Lamp
The LED lamp appears green when the unit is plugged into a
valid AC source.
3. Adapter
The adapter converts alternating current into constant DC
voltage for the computer.
4. AC Plug
The AC plug plugs to the AC wall outlet.
Warning:
Make sure that you are using a standard 3-prong AC plug with a
ground pin. If not, you may feel a slight tingling sensation when you touch the
computer’s metal parts such as the I/O ports. This is caused by a leakage
current when the AC adapter is not properly grounded via the ground pin.
However, the amount of leakage current is within the safety regulation and is
not harmful to the human body.
