Re: my samsung galaxy 10 inch tablet wont start. Any tips?
I know this is old, but if you are talking about the OG 10.1, you can hold down the power button and the volume down key to force it to reboot if it's not because of lack of power.
(I had that happen twice and the first time I assumed the tablet died, it hadn't. Just a glitch.) Apparently, this is a common issue with that tablet as it ages.
