Restarting an ipad that is 100% charged because the screen doesn't wake up because of a software glitch (remember, this is the first time apple has put technology into an ipad that reduces power useage through turning portions of the screen on and off) doesn't make the ipad pro a dud. It makes it a machine that needs a software fix, for which there is a temporary solution, and potentially a full solution once ios 9.2 is released.
This isn't the same issue as the surface pro 4/surface book issues (again, for which there are TONS).
If you are having problems with the ipad pro actually charging, then check for a different thread or start a new one. A black screen after a non charge isn't what this thread is about. This thread is about the ipad pro having a black screen (a non waking screen) after a full charge. Any other issue outside of that would be a hardware issue that should probably be an RMA/exchange issue.
Restarting your ipad on a blank screen after a night's charge requires that you hold BOTH the power and home button down at the same time for around 20 seconds or until the Apple logo shows up. If the apple logo doesn't show up after that time then you have a hardware issue which should be fixed by exchanging the ipad. This is not a general my ipad doesn't work thread though, it's a thread regarding a specific problem which is that the ipad charges up (even up to 100%) but after some time the screen does not wake from sleep. The fix is quick (a hard restart) and the ipad doesn't have anymore issues until the next time that you charge it up.
Also, the ipad is a tablet, it's not a laptop, thus people who complain because they're leaving it plugged in constantly need to recognize that. I get almost a full day's use out of an unplugged ipad. (although, I'm not talking about 8 hours of constant gaming).
Finally, for all those people who keep complaining that Apple is unresponsive about this please reference the link: If your iPad Pro stops responding and the screen is black - Apple Support
i.e They are AWARE of the issue and are working on a fix. I have dealt with every major computer company (Dell, IBM, Compaq, HP, Packard Bell, Gateway; although, when Ted Waitt was CEO they were great, Frys, CompUSA, BestBuy, Toshiba, etc.) and Apple is the only one that in general makes things right for the consumer the majority of the time. In fact, I just took a 2011 macbook pro 17 in for the defective video card/logic board problem for which they are replacing for FREE because enough people have had the issue. Just because apple requires a large window of consumer visibility for a problem doesn't mean they aren't responsive, or don't want to make things right, it means they're ensuring that the issue is widespread and reproducible.
