    And this is the reason, just for fun check original power supply output and you would be surprised it's almost like a laptop up to 30-Watts.
    Main reason why ppl. blow their switches by using regular iPhone charger...
    You need PowerBank with fast charge at least, does ur support it?

    What if your switch is totally ok, do you have opportunity to check your charging devices with other switch?

    You might have some Rat at the board 0.5 amps should heat something. I would use freezer spray or tried to find it on touch.

    I can't solve the problem. In the dock it charging perfectly but on the usb C cable that neither it nor it organizes in win 7 or 10 and on the switch it appears the message that it cannot charging. I tried several cables on several laptops.......:wacko::cry:
    I measured with the multimeter everywhere I was advised to measure. I didn't find anything right. The only anomaly is at the diode near the usb c port which shows me 5v on both sides although I know it has to 5v with 3v.

    The part closest to the usb port is a fuse not a diode, voltage coming in should be the same on both sides.

    So your plugging your switch in to the usb port of a computer or power bank or what ever else, which all give out 5 volts and because you've got 5 volts on the top of the fuse/diode you think that could be your issue.
    Sorry but i don't think changing that part will make any difference.

    I had a short on a cap near BQ24193 and thought perhaps it was the chip - the short however is still present once I removed the chip. It is this cap:

    Anyone know what this could relate to?

    Plug the charger in and see if that cap get's hot, don't leave it in for age's though.

    Check in the usb port to make sure all pins are ok

    Noticing, aloof from it all
    Now I feel ripped off again. I had a day one Switch that I sent to repair by a member on this site over at the trading forums, and when he said he was gonna send it back cause he couldn't repair it, he didn't reply after that and never did send it back. Lost my chances of hacking a Switch or repairing it. Sad.
