Why does my Windows 10 Laptop fail to hibernate sometimes?

Question

After I click 'Hibernate', my laptop does hibernate, but only sometimes. Other times, the screen immediately fades black. But then the power button stays illuminated, and 10 s later (after I clicked 'Hibernate') the screen reappears, with everything before still opened.In both cases, my laptop had the same 3 USB devices plugged.

Disabling Wake Timers and seeking the Wake Source didn't help:

Performing the steps in this answer, didn't help. See this for my most updated energy-report.html.

Answer 1

Bingo!!! I seem to have successfully troubleshooted and resolved a similar issue with the help of this reddit post: Has anyone else noticed that their computer no longer goes to sleep automatically after updating to Windows 10?

Steps to troubleshoot:

1. Using the Power Efficiency Diagnostics Report

As already mentioned by Harrymc, you can use the powercfg -energy command to get a report of its power-use diagnostics. The result may indicate errors, warnings or other useful information and is stored here: C:\Windows\System32\energy-report.html

For example my summary report was:

Energy efficiency problems were found.

9 Errors
24 Warnings
43 Informational

See C:\WINDOWS\system32\energy-report.html for more details.

2. Using powercfg -requests

Typing powercfg -requests into a command prompt (might have to be elevated). should tell you what programming is keeping your PC awake. For my report I got:

C:\WINDOWS\system32>powercfg -requests
DISPLAY:
None.

SYSTEM:
[PROCESS] \Device\HarddiskVolume4\Program Files (x86)\Connectify\Connectifyd.exe

• Overriding the programming keeping windows awake. Using the command

  powercfg -REQUESTSOVERRIDE

  tells windows to ignore whatever is keeping it awake and go to sleep.

For instance according to my report I had to override the Kernel Driver and Connectifyd process.

Note! You do not have to necessarily override it, because it the given driver might be keeping the PC awake because its in use, a good example is the Intel Audio Driver above, after stopping the audio its no longer active.

My culprit was the process - Connectifyd.

Nevertheless to override type this commands accordingly:

powercfg -REQUESTSOVERRIDE DRIVER "The Name of Your Device" SYSTEM

powercfg -REQUESTSOVERRIDE PROCESS "The name of Process" SYSTEM

e.g

powercfg -REQUESTSOVERRIDE PROCESS "\Device\HarddiskVolume4\Program Files (x86)\Connectify\Connectifyd.exe" SYSTEM

Answer 2

Seems like the issue may be due to USB Root Hub being allowed to wake your PC. Would you try unchecking the box to see if it works? Steps below:

1. Search for "Device Manager" in your start bar.
2. Once Device Manager is open, near the bottom, expand "Universal Serial Bus Controllers"
3. Locate "USB Root HUB". There will likely be more than one. Do steps 4-6 on each USB Root Hub.
4. Right click USB Root Hub > Properties > Power Management.
5. Uncheck "Allow this device to wake the computer"
6. OK - Test solution. If the solution doesn't work, try a reboot before rechecking the boxes.

Let us know if this works!

Answer 3

An examination of your powercfg -energy report did not show any anomaly. Your system is reported as hibernation-capable (S4) and there are no obvious problematic devices (although it would have been better to make it while you were not using the computer or playing music).

Below is some advice which might help.

1. Turn Off and Disable Hybrid Sleep

2. Prevent devices from waking your computer, and especially the network adapter, in Device Manager. You may list all these devices by running powercfg -devicequery wake_armed.

3. Check Windows for corruption via sfc /scannow. If problems are found and corrected, do not assume that they were fully fixed.
