Win 11 will not load after coming out of sleep mode

Copper Contributor

This all started about (3) weeks ago, I did a windows update, and put my PC into sleep mode for the night. Next day, I use my mouse to come out of sleep mode, my case lights and fans all came to life, but my monitor stays blank, as in no video input coming from my system. I had to hard power off and cold boot.
Couple of days went by, problem persist, and another windows update wanted a restart, my PC logged out of windows, but it would not restart, monitor stays blank, with no video signal. Cold booted, and attempted to do a normal restart from windows, but same blank screen.
Disconnected from my Discrete graphics card, and connected my monitor to my motherboard's on-board graphics, same issues, windows won't load after coming out of sleep mode or do a normal restart.
Friday, I got notification of windows update, updates were successful and my system actually restarted. After my desktop loaded, I did a normal restart, and now Win 11 restarts with no issues, but the problem persists where Win 11 will not load after coming out of sleep mode.

Hi @Gunner1160,

If you're facing issues with Windows 11 not waking up from sleep mode, here are some steps you can try to resolve the problem:

1. Update Your Drivers: Make sure your drivers are up to date, especially graphics and chipset drivers. You can manually update them from the manufacturer's website or use a driver updater tool.

2. Disable Fast Startup: Fast Startup can sometimes conflict with sleep mode. To turn it off, follow these steps:
- Press Windows+R to open the Run dialog.
- Type "powercfg.cpl" and press Enter.
- Click on "Choose what the power buttons do" on the left.
- Select "Change settings that are currently unavailable."
- Uncheck "Turn on fast startup (recommended)" and save changes.

3. Adjust Power Settings: Incorrect power settings can hinder sleep mode. To modify them:
- Press Windows+R to open the Run dialog.
- Type "powercfg.cpl" and press Enter.
- Click on "Choose a power plan" on the left.
- Select your current power plan.
- Click on "Change plan settings."
- Access "Change advanced power settings."
- Expand the "Sleep" section and "Allow wake timers."
- Set both "On battery" and "Plugged in" to "Enable" and save your changes.

4. Disable USB Power Management: Prevent Windows from disabling USB devices during sleep mode by following these steps:
- Press Windows+X and select "Device Manager."
- Expand "Universal Serial Bus controllers."
- Right-click on each USB controller, go to "Properties."
- In the "Power Management" tab, uncheck "Allow the computer to turn off this device to save power."

5. Run System File Checker (SFC): SFC can scan and repair corrupted system files. To use it:
- Press Windows+R, type "cmd" and run as administrator.
- Enter the command: "sfc /scannow"

6. Run DISM Tool: The DISM tool can tackle more serious system problems. Follow these steps:
- Press Windows+R, type "cmd" and run as administrator.
- Enter the command: "DISM /Online /Cleanup-Image /RestoreHealth."

7. Reset Windows: If the issue persists, you may need to reset Windows. Keep in mind that this will restore Windows to default settings but retain your personal files. Here's how:
- Open the Settings app (Windows+I).
- Click on "System" and then "Recovery."
- Under "Reset this PC," select "Reset now" and follow the on-screen instructions.

If these steps don't resolve the problem, it's possible there's a hardware issue. In such cases, seeking help from a qualified technician for diagnosis and repair may be necessary.

I did every step except reset windows 11, none of them made any difference. This has more to do with the motherboard and windows not being able to communicate with each other. System wakes from sleep mode, case lights and fans all come on, but there is no video signal coming to the monitor, hence a blank screen.

@Gunner1160  same here no solution at all

There is a general problem  with the sleeping mode of windows 11 since 23H2 was deployed for laptops.


Some laptops are able to come out of sleep mode but some parts stay in sleep mode and cause the laptop to be very very slow, with almost no responsiveness. Especially for those who have a cpu with efficiency cores. I suspect the OS to remain on efficiency cores after wakup.
