So the title is exactly what happens... It's an odd one. I have a 2015 15" MBP and whenever its being charged, then its fine and I open it up from sleep and continue as normal, unless while its been charging it hits 100%, in which case it turns on to a black screen, sometimes with a cursor appearing but will not go any further. The only fix is to shut it down by holding the power button. Any ideas on a fix for this? I'd like to find out if its software related or hardware. Thanks everyone.
