Surface Pro 4 - Screen won't wake from sleep

I have exactly the same issue. I just bought SP4 256GB 8GB yesterday, it was fine. Last night 12/Nov/15, I have installed latest update, google chrome and steam. This morning it was fine, but in the afternoon, all the sudden, it won't wake up on power button. I had to hold down power button for 30 second to do a reboot, and it started to have the same issue ever since when SP4 is put in extended sleep.  The symptom is that the keyboard works but screen wont be turned on. I cannot find a solution either, mostly related to SP3 and SP2. Should I return it? I really hope it is just a software bug.

Hey all!

Just bought a Surface Pro 4 (128GB SSD/4GB RAM/i5 version) at the Microsoft Store here in town about a week ago. I love the device, and have since I worked in the MS Store back during the RT launch. Having a little issue though, that maybe you guys can help with or, if you can't help with it, perhaps you're experiencing it to and we can mutually b**** about it. I've seen plenty of threads about this regarding the Surface Pro 3, but none for the 4, and there are minor variances in the symptoms on mine than on those.

Bottom line: when the Type Cover is attached and I fold it down to get to work, the screen's supposed to wake up as the tablet comes out of Sleep Mode, right? Well, for me, 1 in every 3 times I do that, the screen doesn't wake. The tablet is clearly on and recognizes it's been opened - you can tell because the wonderfully-backlit Type Cover glows with enthusiasm to help me with whatever document I was about to bang out - but the screen stays dead and black, the lazy son of a gun. 

I can remedy the issue with a hard reset (power button for 30 seconds), but I mean, come on - what if I've got a document in the works I haven't saved yet?

The only thing I can think might have anything to do with anything is that the problem started shortly after the Facebook Metro app (do we still call them that with W10?) offered to change my user pic and lock screen to mirror Facebook's, which I accepted but... no way, right? Those photos are stored locally, I'm sure, so it couldn't be refusing to render the lock screen because it's having trouble fetching the photo or something.

Any insights would be helpful! All settings are out-of-the-box default. Problem seems most frequent when I don't let the screen wake up organically but instead press the power button after opening the Type Cover, redundantly.

Known issue.  Work around for now is to change power settings for close lid from Sleep to Hibernate -  will take a few more seconds to resume but will prevent the device from turning on while in your bag.  The thought here is it is Windows Hello doing this.  If you have enabled that, you can also disable it for now too.   Personally, I hibernate.

And the other thing to do too, is go into Device Manager and under Batteries update the driver.  Right now you should see something dated 2006, once updated it will be 2013 and this helps resolve this issue too.  Maybe try this first and see how things go.

Update:  Last night I spent over an hour with a tech over the Chat support forum.   He confirmed that I had all of the latest windows firmware drivers installed and then proceeded to delete all of the drivers from devices, go to the download site and reinstall all of them.   I closed the lid and went to bed.  This am, opened the device to a blank screen at the airport, yet it was running in my bag the whole time.   Not only did I lose 20% of my charge, but I had to hard reboot it again.

Do I need to return the device?   This is a non-starter for a Tablet/Laptop.   I need to be able to leave my device in a prepared state with all of my client data ready to go when I open it.   I can't even use it if I have to shutdown and restart every time.

Microsoft - this is a critical issue.  Please help.
