HP envy 17t gets very hot and dies while sleeping, requires plugging in to boot back up

[NateMk50]

Product is a 17.5" Envy 17t-ce000 purchased last fall (2019) so is a fairly new product. I am a college student and as such I will frequently put the laptop in sleep mode and close it rather than shutting down, so as to take it with me and quickly use it again. Sometimes, seemingly at random, the laptop will shut down completely, becoming very hot and completely unresponsive (power button does nothing, etc) until I plug it in. Upon plugging the laptop in it boots up and shows the battery at some normal (not dead) percentage, most recently 80%. I do  not understand why this is happening, I have run a battery diagnostic and it came back normal. Please help.

The problem with using the new Win10 Hybrid Sleep is that some folks report their laptops waking up spontaneously, and when those are contained in backpacks (which is very common these dauys) they often overheat and crash with thermal shutdown.

Sometimes, this is OK; other times, it trashes the PC in the process.

So, my advice would be to disable sleep and disable FastStartup (more on this below) and just shutdown the laptop.  Yeah, I know it will take longer to boot up, but at least it won't burn out in the process.

Win10 has enabled a new hibernation process known as Fast Startup -- which is enabled BY DEFAULT.

This is different from Fast Boot, which is a BIOS/UEFI option.

Fast Startup is supposed to dramatically speed up the booting process, but in some PCs, it actually slows it down or causes it to hang. It's also a new form of hibernation known as hybrid sleep -- and this causes battery drain to maintain the state of the PC while turned off.

Disabling Fast Startup might fix the booting problem.

There are two ways to disable FastStartup in Win10: (1) through the Control Panel, and (2) through an elevated command prompt.

Control Panel - Open Control Panel --> Power Options.
Select "Choose what the power buttons do"
Select "Change settings that are currently unavailable"
At the bottom of the Window, under Shutdown settings, uncheck the box regarding fast startup

Elevated command prompt - run the following command:
REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_dWORD /D 0 /F

In both cases, reboot Windows.

NOW, FastStartup is disabled.

I don't think that's it, I disabled fast startup a while ago in an attempt to solve the issue but the problem has persisted
