I have the same problem as well.  I changed setting for sleep to what was suggested below by Tayfunto for now but I would like to be able to put it in sleep mode.

I have an HP Pro 3000 Microtower. Upgraded from windows 7 to 10.

I have also tried all the troubleshooting.

There should be an easy fix to this.

Hi Santosh,

I have exactly the same symptoms described in the initial post and nothing mentioned on this thread helped (troubleshooting, changing power plan, disabling hibernation, updating bios, drivers, etc.). It happened after upgrading from Win 8.1 to 10 on a perfectly working before HP ProBook 450 G2.

This issue kills a lot of productivity and I think deserves attention. Could you please assist us further?

Not sure this problem is related to Sleep, but definitely powering down after some number of hours.  After checking different forums, and finding a bunch of "solutions", found a hidden setting for computer to Hibernate after 360 minutes (6 hours) plugged in and on battery.  Changed 'plugged in'  to 1,000,000 minutes (almost 2 years).  Now just have to wait that long to see if it works. Here is what I did.

1.  Start/Settings/Power and sleep/"additional power settings"

2.  Click "Change when the Computer sleeps"

3.  Click "Change Advanced Settings"

4.  Expand ‘Sleep’ (click on +)

5.  Expand ‘Hibernate after’

6.  Set ‘Plugged In’ to 1000000 minutes (almost 2 years), and click Apply

7.  Click on something else to verify your entry was accepted

8.  Press OK

9.  Restart windows

Verify entry has not changed

10.  Wait 6 hours, overnight, and ~2 years to see if it works.

Finally managed to fix this annoyance!

Here is what I did (after finding the resolution on HP's site):

1) Disable temporarily Windows Update. In Control Panel, select Administrative Tools, and then open Services. Double-click Windows Update and set Startup Type to Manual.

2) Install version 10 of the "Intel Management Engine Interface" (MEI) driver (overriding the newer, already installed but faulty version). I installed version 10.0.38.1036. The installation failed the first time, but on the second it repaired itself. Other versions I tried didn't work. Here is a link to what worked for me.

3) Configure Windows to not update the MEI driver automatically anymore, using this utility.

4) Enable Windows Update.

5) Restart and enjoy a working Sleep mode.

I hope I managed to save some of your time!

Svilen

Update to previous post:

After 4 days running with Sleep Mode enabled, my Toshiba Satellite C850 no longer shuts off when left unattended.  So, I have waited through Sleep Mode, 6 hours (360 minutes), but not the 1,000,000 minutes I set the Hibernate Mode setting to.

Also, just as an aside, I also run a VM Windows 10 Insider version on a Mac, and when I drilled down to the same setting for Hibernate Mode within the advanced power settings, the settings for Hibernate Mode do not exist on that installation.  Go figure.
