I feel a slight fuzziness as if there is stray voltage going through me. It is not a shock per se and the sensation goes away when the charger is unplugged.
SMP (switch mode) chargers will do that if not well designed.

Does my laptop need to be grounded when charging?
I generally leave my MacBook Pro attached to its charger while listening to music files played thru my dac via USB. I have noticed that when I am barefoot and gently rub my finger over the metal surfaces of the laptop that I feel a slight fuzziness as if there is stray voltage going through me. It is not a shock per se and the sensation goes away when the charger is unplugged. The charger does not have a ground prong. Should I ground the metal cover of the laptop? Should I get into the habit of disconnecting the charger when I listen to music files from the laptop? Is this normal?
