It was nothing at all. Have the charger ordered on Wednesday, today there came other so normal delivery time. Property me then equated to work on my laptop. Before I used the cable, I compared a habit for safety's sake again the output power of the cable of the necessary input power my laptop-safe than sorry. Both agreed together exactly match, and not knowing I went to work. After a few minutes a strange smell in the room was spreading, which could not be good. As I looked around, I discovered even a small puff of smoke that rose under my desk. The power I immediately switched off and unplugged my laptop from the cable. A production error? Whatever, I'll probably have to send back the cable: /
