Accidently clicked Idle current in boot menu won't turn on now

My tablet shutoff and won't do anything now since I was in the boot menu and accidently clicked on the idle current space and it immediately went black and has zero sings of life. I have tried all the obvious, holding power button, volume up and down and I'm at a loss please help if you can, understanding this issue even if irreversible would still make me feel a little better, thanks .
