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.
