I'm travelling at the moment and the three-prong plug on my laptop power brick is going through a two-prong adapter and therefore losing the connection to ground.
The laptop stopped charging and I took it to a local repair place. The guy put it down to the power brick and sold me a replacement. This looks like a genuine HP product but could be a copy. The sticker says "connect only to a grounded outlet".
I have had several electric shocks when handling the plug. Does this mean that the power brick is faulty, or is it normal given that it is not grounded?
