Won't charge or turn on

Hi @dzuhfhfw7tdsdrk

If it won't charge check the charger or charger cable (try using different, compatible, known working ones) and if they're OK, use a magnifying glass and a strong light to visually inspect the charge port in the tablet.

Check that there's no lint or other debris in the port enclosure that may be preventing a good electrical connection and also that all the pins are there, and that they're straight and parallel and not bent etc,

If there is any debris in the port enclosure, do not use a pin or metal probe to try and clear it. Try using a vacuum cleaner and check if that removes it.

If all the above seem OK the tablet will have to be opened and tested to find out what's wrong.

Here's the ifixit Samsung Galaxy Note 10.1 2012 guide that may help.
