Apple on Thursday posted a new support document on its website, responding to complaints about iPad Pros suddenly going black and refusing to accept touch or button input.
The issue can be temporarily resolved by force restarting, Apple said. This involves holding the Home and Sleep/Wake buttons simultaneously for 10 seconds or more until the Apple logo appears onscreen.
The company added that it's "investigating" the glitch, but didn't indicate whether it was working on a solution, only promising that it would update the document as new information emerges.
The blackout problem has been known since the Pro shipped last week, with some owners complaining on Apple's support forums and to sites like AppleInsider.
A common factor appears to be charging. Numerous anecdotes have pointed to blackouts occurring after charging the tablet for an extended period of time.
