Windows 10: Why does my PC refuse to wake from sleep?

I've been having the issue with my PC where it won't wake from sleep. I press a key on the keyboard or wiggle the mouse and it seems to wake up since the light on my external hard drive comes on apart from the display is black. The only way to get it to properly wake up is a hard restart. What is causing this? I have all the updates and latest drivers installed. I have tried to unistall windows updates to see if that was the issue, but it doesn't make any difference. I have tried to do a fresh install of Windows 10 and it fixed it for a short while but the issue came back. However, I di

wake from sleep issue in windows 10

Hi,

Thank you for posting your reply. Apologize for the delay in response.

I suggest you to check which devices are configured to wake up the computer from sleep by following the steps below:

• Right click on Start icon and select Command Prompt (Admin).
• Type the command line below:

Powercfg /devicequery wake_armed

3. Check if the devices (Keyboard, Mouse, Ethernet cable) are listed.

If the system is not going to sleep and going to Hybernate, the only option to wake up is to press the Power button.

Hope the information is helpful.

 

Troubleshooting PCs spontaneously waking from sleep

I've also battled with sleep/wake issues over the years, and from experience have learned that trying to find, or rationalise, the root cause is a waste of time. All you need is `powercfg`.

`powercfg -devicequery wake_armed` from an Administrator PowerShell window/Command Prompt will give you a list of all devices that can possibly wake the PC. This command is interesting because very often, it will show devices that you'd never expect being able to wake your computer. I think in one instance I had the chipset device listed!

`powercfg -devicedisablewake "device_name_from_device_query"`will prevent said device from ever waking the computer. This command is 100% the only thing I have found that will resolve sleep/wake problems. Updating drivers, unplugging peripherals, switching to a cleaner power supply (UPS), changing ethernet cables... none of those have helped, yet`powercfg -devicedisablewake` has done the trick.

Note that occasionally, devices you have disabled wake for may start waking up the PC again - this happens if you plug a USB device into a different port, or occasionally when drivers are updated, because Windows sees it as a new device. In that case rerun `powercfg` to find and disable that device again.

If this does not resolve your wake issues, I would start looking at power fluctuations.
