AC Adapter
1. DC-out Connector
The DC-out connector docks to the power jack (DC-in) on the computer.
2. Adapter
The adapter converts alternating current into constant DC voltage for the computer.
3. AC Plug
The AC plug plugs into the AC wall outlet.
Warning: Make sure you are using a standard 3-prong AC wall socket with a ground
pin. If not, you may feel a slight tingling sensation on any of the computer’s metal
parts such as the I/O ports. This is caused by 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.
