There is a reset hole on the hi13, if so, where? Anyway I am planning to do the latter, just gotta get myselfs some torx screws. Thank god the screen has not been glued in.
Bump, so I have opened the tablet to disconnect the battery, but this didnt fix it. There is something else going on, whenever power is applied (battery disconnecting/reconnecting) the cpu starts to get warm (up to a point where i can still touch the heatsink, so not hot in the sense that its burning up it seems). The batteries however stays cold so its not pulling that much power so i am not really sure if its shorting out or not.
I think i will leave the battery disconnected for a few hours and report back, although the tablet is unfortuntely toast to my believes. Maybe someone else has a godlike idea?
Sorry for the late response, maybe you still have the problem.
Recently I’ve had a similiar one, the problem wouldn’t start, there wasn’t even a bootlogo at startup.
What helped was the following key press combination for the power button: Three times short press (about 1s) then one time long press (10s). Then you wait for 10 seconds until you can press the power button to start it.
