Last Friday, after an usual work day with my iPad in side-car mode, I disconnected it from my macbook pro and let it sleep.
Today, when I wanted to use it again, the screen remained black. I tried the force-restart (
volume up button then
volume down button then
power button during 5-10 sec, even 30…) with no success.
I also tried to charge it but still pitch-black.
Any other idea before Apple support…
