Surface Pro 2017 turning off or hibernating randomly!!!

I think it is related to the Bluetooth driver and/or marvel bluetooth adapter itself.  I mostly use the new Surface Pro connected to power but I still get random issues (NOT shut downs) with the Microsoft Arc Touch mouse (not the new one, the previous version) where the centre scroll just stops working. I will see events listed saying the Bluetooth driver has malfunctioned and has been unloaded.  I have also been using the SP4 Signature Edition keyboard with the new Pro and that seemed to cause it issues but they seem to have settled down.

Random sleep in tablet mode only happened in the first few days and I put that down to all the app and os updates that were going on in the background. Since then it has happened only two or three times but maybe it isn't happening because (a) I am using plugged in and (b) I rarely select 'tablet mode' even when I use it as a tablet without keyboard and mouse.  And I never let it adjust brightness automatically.

However, in the Notification panel my Brightness button has stopped functioning - anyone else have this? Just started today.  Clicking that button does nothing instead of cycling through the brightness levels. Will have to reboot and see if that fixes that issue.

I like the new SP enough I think I'm keeping it (have another week to decide) but that is largely because I have the MS Complete and will have two years warranty.  

That said it may be something else software update related as well as my Surface Pro 4 (i5, 8GB, 256GB) which has performed absolutely flawlessly for a year has just started to act weirdly in tablet mode. When I wake it after it has been hibernating over night the screen is getting interference type lines in the top inch of the screen. The screen will then adjust the lighting way up, way down, and finally cycle into acceptable visual range. The screen then ends up normal and beautiful like it always was. The only Bluetooth device I am using with it is the SP4 pen.  I moved the keyboard and arc touch to the new one until I can get the updated versions down here in Australia.

I wonder if the second problem has to do with the Night Light function which dims the screen... it seems to have started around the time I activated that. Could be coincidence.

I feel you James, I too had to wait multiple hours on the chat queue just to have someone try and take me through some ridiculous hoops that I had already gone through (which I explained to the "support" staff) to come to the conclusion that A. they don't listen/nor understand what we are trying to explain (e.g. your local account that you had to create to try and attempt to log back into your device) and B. in the end after the hours of trying to explain ourselves we get a generic answer and are nowhere near closer to knowing what is going on.

MICROSOFT... listen up! all we are chasing is acknowledgement of this issue, which is clearly wide spread, and some form of information/update on what the issue is and when it will be fixed. Even if you don't have a fix right now at least let us know an estimated time frame or what our options are! We (your customers) have spent Hundreds if not thousands of dollars on these devices just to be let down majorly! The least you can do is give us some feedback/communication on this issue, you are losing customers left right and center. (please and thank you)

Update - I changed the "what happens when you close the lid" setting and haven't experience the problem in the last 1.5 days of heavy use, plugged in and not plugged in. It is now set to "do nothing". This makes me think that there's a sensor misfiring (probably a driver - if it was the hardware, you'd see more bizarre behavior) and perceiving a hand motion as a lid close. 

Wild speculation - anyone else that is experiencing this wear a smart watch? What if it's picking up something from a smart watch close to the sensor and thinking that is a lid close? Total speculation, but if sleep on lid close is the problem, then it's got to be picking up the signal somewhere.

Last thought, I'm not returning as I do not have concerns about having to replace this with a refurb. I come from the PC world. "new" laptops come off an assembly line and receive a baseline quality check. Refurbs for reputable manufacturers receive a much more thorough check because they are refurbs. Just food for thought.

Sorry to say, but I don't think "what happens when you close the lid" setting is related...

I changed the setting right after I read some comments in this forum, but still my SP goes hibernating.

Just opened up the same topic in Japanese forum with a desparate hope to draw people's attention...
