Yesterday my ipad pro 12.9 2nd gen screen turned black. I tried hard restart several times, but to no avail. I plugged into the computer it doesnt recognize it, but mind you i have never plugged it in to a computer before. so I dont know if would recognize it. I found a program on the internet that does diagnostic repairs and what not. I had the iPad connected to the computer and tried to put it in recovery mode and the screen goes brighter (a faded white screen with a black border) and the program did recognize it was a ipad pro 12.9 2nd gen, but iTunes does not recognize it. So I’m not sure if that means anything Everything was working just fine before my screen went black. The touchscreen, home button, sleep/wake button, its fully charged 100%, etc. I can still see a faded back up light when I press the home button or sleep/wake button when the room is pitch black. I went to the apple store and they said it wasnt giving off charge only a 1/10th of the power. I’m not sure if it’s the ipad is dead or display is gone or maybe i0s problem?
Even if you have never plugged into a computer before, it would still be recognized by one if it was booting and powering normally. You just wouldn’t be able to sync it or backup without being able to enter the password. You can also try putting it into recovery mode to see if it’s recognized. Which would also allow you to try and process an update, if it is in fact a software problem causing it to not boot. This might be tricky if you can’t see the display, it will likely be a bit of a dance with timings, but it would at least tell you the device is responding. If you took it to the Apple Store and they ran their Integrated Circuit Checker, which is the tool that’s used to see if a device is capable of powering on, those can also give false results (can indicate it’s not capable of turning on, or it’s drawing very little power) if the device is actually on and the screen is locked. But this still sounds to me, like if a computer is not recognizing the device, it’s probably not software.
