Surface Pro 4 - Screen won't wake from sleep

I still have no idea why we're learning this from the Windows press rather than an honest and informed Microsoft spokesman, but Paul Thurrott has an article on his site today that digs into some of the potential reasons for the power management debacle: https://www.thurrott.com/mobile/microsoft-surface/64867/trying-to-explain-the-surface-sleep-problems

His article does implicate the Skylake chipset, and flags the point that Microsoft is the first to try to make this power management method work.

The bad thing is that the article pretends that all is fixed, when it quite clearly is not - at least for a great many of us.  On the other hand, my machine woke correctly after being put to sleep with the power button today - time to celebrate!  (Except that two desktop apps were crashed on wake: Firefox and Sublime Text - I'm not sure whether those are Win32 or x64 apps - I'll have to look...)

There's one more datapoint for at least some of the remaining problems being related to the keyboard cover - The cover was not present when I put the SP4 to sleep, and it was removed before I woke it successfully.  (BTW, both the SP3 and the SP4 have always been a bit flaky with the keyboard cover folded back out of the way (at one point, booting the SP3 with the keyboard cover folded back failed or did something bad - I don't recall what.  I expect there are subtle bugs in the keyboard position sensor/state code that have been hiding out for a couple of years now.)

It's pretty sad when we get excited about something like wake/resume just working as it should, though.  Further, I'm quite disappointed that MS isn't owning up to this and communicating with us themselves.  It sounds as though they really are trying to offer a best-in-class experience, it's just not working yet.  (Boy, is it not working, yet...)

• i5/4/128 - No dock or type cover.
• All Feb 17th updates installed. 
• on and off all day for note taking with stylus & OneNote. 
• using sleep  (hibernate set to "never")
• Turned off "password required on wake" and for the first time since the Feb 17th update I have not had a single issue waking out of sleep after approx 20 sleep/wait cycles. Sleep function appears to be working correctly with approx 1-2% battery drain per hour when not in use.

Of course not being able to use a password (or PIN) is never acceptable so the above is definitely not a solution, just another data point.

I'm with you. I have a 7 year old Thinkpad running the Windows 10 Insider Fast Ring that I still use for a lot of my day-to-day, because despite it's nearly dead battery, the fact that it's running a truly Beta OS, and its old tech, it is still much more reliable than my SP4

Outside of this sleep issue, I love it. My notes are the exact same as yours. When it is set to hibernate, everything works. No battery drain, no heat, no dead screen. The thing that irks me the most is that Microsoft said they fixed it. A lot of people disagree with that including myself. And we wait in silence. We all paid a lot of money for these and we expect it to just work as it should and not have to fool with workarounds while Microsoft is mum on everything. That being said, I still love the device for what it does for me. When it is on and I'm using it, it's amazing. It's when it's not on is when the trouble begins, if it's set to sleep anyway, and apparently for some, when even set to hibernate.
