win 10 Laptops turns off

I have my HP laptop set to Sleep, when I close the lid. That has
worked as ecpected, since I owned it - ~2 years.

Most recently, when I open the cover, there is no response. I now need
to do a Forced power down and reboot. It may be an umrelated
coincidence, but that problem seemed to happened at the same time I
was FORCED to accept another Win 10 OS update ??

I have checked the power settings, still shows Sleep when closing the
lid.

Any ideas, will be most appreciated. The current situation, requiring
a reboot is most frustating daily exercise !!

Do you have room for a hiberfil.sys on C: ?

An alternative to Sleep is Hybrid Sleep, which writes hiberfil.sys
and if the machine crashes in sleep, the hiberfil will restore
the session for you.

If you did

powercfg /h off

at some point, to delete the hiberfil.sys, then any instructions
you follow for doing Hybrid Sleep won't work. You can turn on
the possibility of Hybrid Sleep and Fast Start by doing

powercfg /h on

as an Administrator-group user. Laptop users don't normally
do stuff like that, but I have to mention it. On a laptop,
some form of hibernation must be enabled, for "battery-safety".

Hybrid sleep means slower shutdowns than regular sleep,
but it offers the insurance that a sleep-crash is backed up
on disk and the session is not lost. Hybrid sleep would be
fast enough with an SSD C: drive, to be "almost transparent"
to the user.

If this happened to me, I would try to test hardware sleeping
works properly - using a Linux LiveCD. They have sleep in their
menu etc.

*******

Sleep powers off everything except RAM. The RAM is put in
"auto-refresh" mode, the clock signal continues to run on
the RAM chip inputs, and the RAM chip visits memory locations
on a regular basis (every 8 milliseconds maybe) to keep the
gate charges loaded while it sleeps. This draws around 1W of
power. That's the hardware component of sleep. When the battery
gets low, the OS switches to hibernate, and writes out the
RAM, before it's too late... Why would this crash ? If
the content is corrupted, it cannot recover when the
Program Counter register is reloaded on wake.

*******

You can also try testing sleep without using the lid.

In Windows 10, use the power menu item on the Start menu,
select Sleep from there, then tap one of your HID (keyboard,
mouse, trackpad) inputs to wake the machine. Check Device
manager, for the HID devices, to see if the waking option
is enabled for it. Pick a HID device you won't be triggering
by accident. Even plugging in a mouse, setting mouse-wake
in Device Manager in the mouse entry, could be used for
a quick test. When that mouse is unplugged later, then
the system will work as normal.

The powercfg utility has extensive features, to log power
events and give feedback. So if you're having problems,
that's one place to do some work. There is an "energy report".
There is "lastwake". And Windows 10 also has a "reliability monitor"
with failure logs in it.

The Event Viewer may also be logging some important information
you should be looking at.

Yep, that probably did it.
