Strange vibration felt through fingertips when plugged in
In all my years of working in IT, I've never encountered this.
It seems when I rub my fingertips on the lid of the MacBook Pro (only two months old) when the power adapter is plugged in, my fingers feel this weird sensation of vibration -- as though they were brushing against rubber.
But when the laptop is running on battery power alone, the sensation does not occur.
My wife confirmed this so I'm not totally nuts here. I also tried to see what would happen with the battery out but plugged in -- the "problem" persists.
This is clearly some weird electrical problem. Should I be concerned?
