Is my Ipad 12.9" 2020 ('s battery) dead?
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??
iPad Pro 12.9-inch, 3rd Gen, Wi-Fi
