Win 10
driver bundle installed
brand new, couple days old.
If I close the lid, whether plugged in or not, for more than say 20 minutes?
I open the lid to it rebooted, and a message. Pic as soon as I figure out how. 
Default Boot Device Missing or Boot Failed. Insert Recovery Media and Hit any key
Then Select 'Boot Manager to choose a new Boot
[Ok]
We believe we have root caused this to an SN850 firmware issue on some version of the firmware. Updating the SSD firmware has resolved the issue in each case we have come across: My system is rebooting to a “Default Boot Device Missing or Boot Failed” message
I installed a new WD Black SN850 2 TB. Installed Windows 10. Installed all updates. Changed settings to display only on external monitor. Changed power setting to Do Nothing after closing the lid while plugged in. Shut lid. Came back 3 hours later and it wouldn’t come to life. Clicked keys, clicked mouse, nothing. Case was too hot to handle. Power switch light was blinking. Held power switch down until light went off. Started machine. Fan kicked in at high speed. Case cooled down and fan went quiet. I’m concerned I may have shortened the life of the unit.
I just got the laptop today. I have windows 10 installed. I closed the lid and plugged it in and tossed it on the bed. I came back an hour later and the fan was spinning extremely fast and since the vent was facing the bed covers, it couldn’t breathe.
How do i just make it sleep/hibernate and not try to cool itself down? Or am i missing something. Thanks!
Is Windows set to suspend if the lid is closed?
I’ve seen this issue with other brands. Maybe some application was preventing sleep?
New firmware is suppossed to address this
Gotcha, I am showing 3.06 bios version. Not sure what version i can upgrade to.
On Windows if an audio player is open deep sleep will not be entered, and for some reason the system will just heat up. On Windows if you are suspending and charging make sure you always close any audio players before you suspend.
3.06 is current I believe. It must be a windows thing, as I have not had any issues like this with Fedora.

Understood.
I am using a Sabrent Rocket Q 2TB (SB-RKTQ-2TB).
Does that change anything?
I updated the firmware and my machine still isn’t going to sleep when told. I don’t yet know what will happen overnight. It would be nice if it would boot okay after this upgrade, but I really want the machine to sleep when it is told to.
For the system not going into hibernate, this is more than likely the irritating default behavior in Windows 10, where it does more work than makes sense to in Modern Standby. Especially bad is that on a fresh Windows 10 install, it will run the search indexer while in Modern Standby for the first few days to build an initial index.
You can force Windows 10 to use hibernate instead of sleep, but that is not necessarily ideal either:
I did that right before your post. Hibernate is working as desired, except for the slower wake up time than sleep. Hibernate puts the machine to sleep. I will see if the case is cool in the morning.
Do you have a solution to fix sleep? My $280 HP Costco special has zero problems with sleep. If other laptops can properly sleep, this one should be able to as well.
