Answer to: Why won't my tablet turn on?My Samsung Galaxy Note 8.0 (wifi only) will not switch on or respond in any way to a known-good charger being plugged into it. It hasn't had much use since new, and still looks like new, so I don't believe it's a worn out battery or switch. It will not reset, or hard-reset, so I have removed and tested the function of the power tact-switch, that that works perfectly, at least up to the connector that goes to the next board. The battery shows as having 4.2V. I fear that I've bricked it. Nothing I do gives any response. Is there anything else I can try?
