Windows 10: Windows no longer waking monitor after pc being a sleep

Hello,

Can anyone help me figure out my problem here?

Over the past couple of weeks I've had a issue with our PC monitor, well I thought it was the monitor. When the PC goes to sleep and you wake it up, it won't bring the monitor back to life.

After trying numerous work arounds, button presses, keyboard punches, God's being called out etc. We went for a new monitor, however the issue is still occuring.

I've checked to see if there's any new GC drivers, there isn't and I've not had to update these in a while. It's not a gaming PC, it's a slimline and the GC is onboard (I know...the horror).

We've never run into this monitor issue before, normal it fires up almost immediately.

Any help on this will be fantastic, thank you.

Monitor Not Waking Up After Sleep

I am experiencing a critical issue - when my computer goes into sleep mode, or if I manually place it in sleep mode, the monitor will not wake. The PC is running; I can hear the fan and the light on the front of the monitor is on, but the monitor itself will not wake. The only way I can get the computer back on is to do a hard reset by holding in the power button, turning it off, then back on. I've tried all the obvious fixes; windows updates, graphic card driver updates, unplugging, turning off sleep mode, turning off Link State Power Management ,making sure the keyboard or the mouse are able to wake the computer in settings, etc. Nothing so far has worked. Any suggestions on how to fix or what the problem may be?
An additional problem is that I cannot even save some new settings in my motherboard. Somehow the settings return to the default settings and the problem remains. The PC purchased brand new almost 4 months ago.

CPU Intel Core i5 8600k 3.60GHz
Graphic Card (integrated): Intel ® UHD Graphics 630
Motherboard: Gigabyte Z370 HD3
OS: WINDOWS 64 BIT

Could you please provide any suggestion?

I look forward to hearing from you.

Kind regards,

 

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.
