8.1. PC Won't wake from sleep mode

Sleep can be a complex system within a PC.  If you are having issues with your PC waking up from sleep, try the steps below to resolve it.  It is not necessary to perform all the steps if the issue is resolved part way through.  This is merely a list of solutions in order of most relevant.

 

1. Mouse or Keyboard Issue

These are the two most commonly used input devices. Since these are used to wake our computer from sleep mode, this is where we should begin. Check if the mouse and keyboard are working correctly. Connect them to a different PC to be sure.

2. Sleep Settings

There is a difference between sleep and hibernate mode. You need to be mindful of their individual settings to make sure that your computer is not going into hibernation before it could go to sleep. If that is the case, you need to press the power button to wake it up.

3. Wake Up Permissions

Your Windows 10 computer’s mouse and keyboard may not have the right permissions to wake up computer from sleep mode. Maybe a bug changed the setting. Search for and open Device Manager from the Start menu.

Double-click on Keyboards and right-click on HID Keyboard Device to select Properties.

Under Power Management tab, make sure that the box for ‘Allow this device to wake the computer’ is selected. Save settings.

Now, repeat the same process for HID-compliant mouse.

Scroll to the bottom of the screen and expand Universal Serial Bus Controllers option. Right-click on USB Root Hub to select Properties and under Power Management tab, uncheck the box for ‘Allow this device to wake the computer’ option.

Allow the computer to go back to sleep and try waking it up again. Hopefully, that should work. If not, continue reading.

4. Update Display Drivers

It could be that the display drivers are out of date. Open the Device Manager again and double-click on Monitors. Right-click your monitor name here and select Update driver.

We also suggest you do the same for your graphics drivers. You will find it under Display adapters.

5. Turn Off Fast Startup

Windows 10 comes with a Fast Startup feature. There are a few pros and cons of using this, and one of them is Windows 10 PC not waking up from sleep mode.

Right-click on the battery icon to select Power Options. You can also search for it in Control Panel. Click on ‘Choose what the power button do’ option on the left pane.

Click on ‘Change settings that are currently unavailable’ at the top, and then uncheck Turn on fast startup (recommended) option down below. Don’t forget to save changes.

6. Re-Enable Hibernation

If the issue persists and your Windows 10 PC is unable to wake up from sleep mode, maybe use hibernation instead. It might take a little longer to wake up but can work as a temporary fix.  Hibernation is known to cause conflict with the sleep mode. Re-enabling hibernation from the CMD (Command Prompt) could solve it. Search for and open CMD from the start menu with admin rights.

powercfg.exe /hibernate off powercfg.exe /hibernate on

Type this command and press Enter to execute it. Exit and check again if your computer wakes up from sleep mode.

7. Disable USB Selective Suspend

Go back to Power Options (just like you did in solution 6 above) and click on Plan settings.

Click on ‘Change advanced power settings’ here.

You will find USB selective suspend settings under USB settings. Click on the Enabled link to reveal a drop-down menu and select disable there.

8. Power Troubleshooter

Press Windows key+I to open Settings and search for Find and fix problems with your computer’s power settings.

Click on Advanced to select Apply repairs automatically option and follow on-screen instructions after that.

9. Registry Changes

Search for Registry Editor in the Windows Search and open it with admin rights from the Start menu. Drill down to the below folder structure.  Start by opening the Registry Editor with administrator rights.

Drill down to the following folder structure:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power

Double-click on CsEnabled file to open it and change the value from 1 to 0 (zero) and save everything.

You are done.  The sleep issue should've been repaired by the steps above.  If not, please feel free to contact Transource support for more information.
