I just bought this adapter at the hotel because I forgot to bring mine from home. For some reason my laptop is not charging when I use this. enter image description here My charger works until ~250V and the adapter accepts 240V.

  • It seems that you have removed the grounded pin, and the adapter has some sort of safety where it won't work if the ground pin is not inserted.. I would insert a toothpick or some wooden/plastic item in the adapter's grounded hole and then plug the charger to the adapter. Do this at your own risk – Nean Der Thal Apr 6 at 10:30
  • I’m guessing from the tags that you are currently in the UK. Power sockets in the UK always have an associated switch, is the switch in the « on » position? Are you sure the socket is powered? Do you have something else you could connect to check? Ideally something with a UK plug to check the socket, and something with another type of plug to check the adapter. – jcaron Apr 6 at 11:03

    @NeanDerThal: The plug on the left is a common design that works with German and French sockets. German sockets provide ground from contacts that touch the side of the plug from above and below; French sockets have a fixed protruding earth pin that fits into the hole in the plug. Nothing has been removed from the plug. – Henning Makholm Apr 6 at 12:08

    I think you have been sold the wrong adapter. I have one which converts from the plug you show to the UK system and it looks nothing like the one you show. – mdewey Apr 6 at 12:54

    If it was some kind of safety feature, that required an earth pin, I would expect that the plug couldn't go all the way in if that feature wasn't triggered. I think the OP would have noticed that and probably mentioned it. In my mind it's more likely that the white we can see in the two main holes is some safety things that will move if pressed, that will also allow the adapter to be used with the wide array of things that doesn't have an earth pin. I would take the adapter, cable and laptop to the reception and ask for help. – Henrik Apr 7 at 7:22
