Surface Pro 2017 turning off or hibernating randomly!!!

I did as wrote Mike PVW.

I have downloaded manually firmware from Microsoft site and instaled on my SP4.

Since then it is working properly!

Previously at least few Times per day it was hibernating.

Download firmware manually. Widnows update is not downloading it

If you can´t install it I would suggest you download the newest recovery image and reinstall the device. Then you´ll have an image that is up to date with the update included

Ok, I hope this helps: This is a firmware update according to the Surface Pro Update History. Which may explain why some people are seeing success hard-resetting the device, going into the UEFI settings and simply exiting.  My Surface was consistently resetting within 5 minutes of being plugged into my dock. Since this hard reset I haven't seen it happen.  Keep in mind I did make sure I had the update from https://www.microsoft.com/surface/en-us/support/install-update-activate/surface-pro-update-history applied before resetting.

It has worked for others as well. Hopefully it does for you too:

"Hold the power button until the unit shuts off. Then hold the power button and the volume up button down when restarting and let it boot into the Surface UEFI menu. Then scroll down and click exit and then restart and voila."

I'll reply in a couple of days to see if the if the fix holds.

Hi SnakeJam, I have difficulty findinf your solution. Could you post it again, I'd like to try the workaround if possible. Thanks!

Sure, here you go. Entire post copied below:

Try this as a workaround that should (hopefully) stop the random hibernation / shutdown.  The following will disable hibernation through the command line interface:

• Start an elevated command prompt (in the search bar on the task bar type "cmd" and right click "command prompt" and select "run as administrator")
• At the prompt type "powercfg /h /type reduced" (exactly that text without the quotes) - this command actually reduces the size of the hiberfile so that traditional hibernation doesn't happen and it is used only for hiberboot.  Alternately you can turn off hibernation entirely by typing "powercfg /h off"
• If you used the first command to change to the reduced hiberfile size, you'll get a response showing the new size of the hiberfile.  If you instead turned it off, you won't get any confirmation
• Close the command prompt window

This has worked for me for about a day, which is admittedly not enough time to confirm this is a valid workaround, but I figured I'd post this so others can try the same and report back.

One thing to note - this essentially disables hibernation, so you'll lose some of the power saving benefits you get while hibernating, but standard sleep mode works pretty well on the Surface Pro.  I'm thinking this is better than the Surface Pro randomly shutting down in the middle of what you are doing until Microsoft comes up with a real solution.

I've included a screen clip of a sleepstudy report over the last 5 days.  You'll notice that over the last 24 hours or so there are no breaks in the line, which indicates my Surface Pro has not shut down or hibernated since I first ran the command.  Over the previous 4 days you'll see a lot of shutdown/hibernation periods (indicated by the line breaks), some of those are random some normal.
