So I've noticed that sometimes when I remove it from the power plug and touch one of the pins I get a nasty shock. I've tried different chargers (magsafe) and they do the same thing. I've got a pair of lenovo chargers at home and none of them do that. Even my eee pc hot brick doesn't do that. The only workaround is to short the powerplug with something metallic, but that might damage the capacitors. Has somebody also experienced this?
