Default Full discharge bootloop

My daughter fully discharged the tablet. Holding power button or with combination with either volume up or down will only show the empty battery icon and then quickly turn off after 3 seconds. So no recovery or download mode boot. I tried this after 1 hour of wall charging both plugged and unplugged.

Anyone experienced this? What steps did you do to fix this issue.

Not with the N7, but with other devices. I had eventually read in a few thread that the issue was sometimes fixed by removing the back panel, disconnecting the battery terminal clip & leaving it unplugged for an hour or so & then reconnecting the battery, replacing the back & charging (without turning it on or pressing buttons).

From experience with the N7, I can tell you the back is easy to remove & really requires no tool, as long as you can slide a thumbnail between the screen & the back body bezel. Just take caution, like rubber gloves (non-powdered) to avoid static discharge (risk is minimal anyway for most) & to also avoid getting oils on the copper sheeting used in the device for heat dissipation. I had touch screen issues that ended up being caused by a loose ribbon cable, so I have opened mine & I did it without tools & there were no seals I had to break. Take a look at the ifixit teardown for a better idea of how simple removing the back is & for the location of the battery terminal block, which really is right there once the N7 is open.

That's actually the other alternative I'm thinking. But seeing no screw to remove the back panel made me hesitant. I'll try that. Also will look at ifixit for demo.

I've read that one has to leave it charging overnight.
