Surface Pro 4 - Screen won't wake from sleep

While I can see the hibernate settings as a viable work-around, I am seriously thinking of getting a refund for this disaster of a problem.  My old PC works better than this brand new piece...

I can't afford to be in business meetings dealing with this issue.  It's a shame because I was really looking forward to running office natively on the Surface.

I've used a Mac for the last 8 years and I don't recall anything that made me want to get a refund on it.  I'm just saying, this is very serious!

Ah, nice trick (the win+P twice). I applied the display adaptor update from two days ago, and I've turned off the hibernate function - so I'm back to sleeping. After two days of only light use it seems to be working much better. I've not gotten the black screen issue yet. I'm cautiously optimistic this last update might have fixed it for me. I'll report back if that isn't the case.

If it happens again, and you can see that the machine is on (the keyboard backlight comes on, for example) but you are getting a black display, try pressing Win+P twice.

Thanks!  This worked for me. My SP4 is definitely "alive" when it's in its black-screen-zombie mode.  I get the chime when pressing the power.  Switching to projector mode and back again reestablishes the tablet's display.    Seems a lot of the bugs I'm dealing with and reading about are display related.  Hopefully a driver update is in the works.

I seem to get along somehow with these settings in waiting for a real fix instead of these pitiful chewing gum repairs:

If I leave the computer alone in a typical group setting where I must behave silently and discreetly, only the screen saver turns off the screen, and I can get the screen back in a second or two.

During longer sessions where the computer is not needed for a longer period, I either close the lid or push the power button, and hibernating begins, from where the screen returns in 15 seconds.

The advantage of hibernating compared with sleep (irrespective if the sleep state works or not)  is that I avoid taking the computer out of sleep accidentally by touching screen or keys or mouse when closing the lid. I think that almost everybody has made this error, noticing this when the fan is unexpectedly whirring and the computer is hot under the lid. (Someone described just this situation in earlier post).

So the computer shuts down only when I shut it via shut off menu (or exceptionally use force shutting if need be). The energy consumption in hibernating state is so low, that I do not need to think about it because in every case I always plug the computer inside the next 24 hours timeframe anyway.
