The power supply was, I closed it with anticipation to finally be able to work again - and it happened exactly nothing. No LED lit up nothing.
In the middle of the emerging panic attack (I have currently no secondary computer, so it can not escape ...) burst my Apple dealer call. My Power supply is already there.
Great relief.
The non-functional power supply from the Amazon order taken for collection. The merchants there was a special trip to the top of the technology, where it (font, etc.) recognized by the serial number and certain other features as a forgery, though as a well-crafted.
Conclusion: Neither does the power supply which it is intended, nor is it original Apple => Stay away!
Actually zero stars would be the appropriate assessment, only this is not possible, unfortunately.
