PC Won't Wake From Sleep in Windows 11: How to Fix It

You put the PC to sleep, come back, press a key - and nothing happens. Or the power light comes on, but the screen stays black. This guide covers both. Work down the list: the first fixes are quick and safe.

If the PC is stuck right now: press the power button briefly once. That wakes most PCs even when the keyboard doesn't. If nothing responds, hold the power button for about 10 seconds to force it off, then start it again. Unsaved work is lost when you force it off.

1. Try the Power Button and Other Devices First

Tell apart the two cases:

Nothing wakes it, not even the power button - skip to steps 5-7 (drivers, BIOS, power problems).
The power button wakes it, but the keyboard or mouse doesn't - the devices aren't allowed to wake the PC. Steps 2-4 fix that.
It wakes (fans, lights), but the screen stays black - see step 3.

2. Let the Keyboard and Mouse Wake the PC

Right-click Start and open Device Manager.
Expand Keyboards, right-click your keyboard and choose Properties.
Open the Power Management tab and tick Allow this device to wake the computer. Select OK.
Do the same under Mice and other pointing devices.

If there's no Power Management tab, or the box is greyed out, you can check which devices are allowed from the command line. Open Terminal (Admin) or Command Prompt as administrator and run:

powercfg -devicequery wake_armed

It lists the devices that can currently wake the PC. To allow one, use its name exactly as Device Manager shows it, for example:

powercfg -deviceenablewake "HID Keyboard Device"

Wireless keyboards and mice: some USB receivers and Bluetooth devices can't wake a PC from sleep at all. Plug in a wired keyboard to test. If that works, use the power button, or check the maker's software for a wake option.

3. Screen Stays Black After Waking

If you hear the PC and the lights are on but the screen is black:

Press Windows key + Ctrl + Shift + B. This restarts the graphics driver; the screen blinks and you hear a beep if it worked.
On a desktop, check that the monitor is on and on the right input (HDMI/DisplayPort). Some monitors go into deep power saving and don't notice the PC waking; turning the monitor off and on helps.
If this happens every time, update the display driver (step 5).

4. Stop USB Power Saving

Windows can cut power to USB ports during sleep to save energy, which stops a USB keyboard or receiver from waking the PC.

USB selective suspend: open Control Panel > Power Options, select Change plan settings next to your plan, then Change advanced power settings. Expand USB settings > USB selective suspend setting and set it to Disabled (on a laptop, for both On battery and Plugged in). If the option isn't listed, your PC doesn't offer it.
USB settings in Settings: on some PCs, Settings > Bluetooth & devices > USB has an option to stop USB devices when the screen is off to save battery. Turn it off to test.

This uses slightly more power on battery. Turn it back on if it makes no difference.

5. Update Drivers and Windows

Sleep and wake depend on the chipset, graphics and network drivers working together.

Go to Settings > Windows Update, install all updates, and check Advanced options > Optional updates for driver updates.
Get the latest chipset and graphics drivers from your PC maker's support page (laptops) or the motherboard/graphics card maker (desktops).

Don't use "driver updater" tools. See how to update drivers in Windows 11 the safe way.

If the PC shows a blue screen when waking, a driver is the likely cause - see DRIVER_POWER_STATE_FAILURE BSOD.

6. Check Which Sleep Mode Your PC Uses

Open Terminal and run:

powercfg /a

It lists the sleep states the PC supports. Newer laptops often use Standby (S0 Low Power Idle), also called Modern Standby, which works more like a phone. Older PCs use Standby (S3). The output also shows states that are not available and why - for example that the firmware or a driver doesn't support them.

If sleep keeps failing, try Hibernate instead: it saves your work to the drive and turns the PC fully off, so there's nothing to "wake". If Hibernate isn't in the Start menu power options, it can be added in Control Panel > Power Options > Choose what the power buttons do.

7. Check the BIOS/UEFI Settings (Desktops Especially)

On some desktops, the firmware controls whether USB devices get power during sleep. Look for options such as ErP, Deep Sleep or USB wake support in the BIOS/UEFI power menu. Names vary by maker - check your motherboard or PC manual before changing anything, and change only one setting at a time.

To reach the firmware: Settings > System > Recovery > Advanced startup > Restart now, then Troubleshoot > Advanced options > UEFI Firmware Settings. Details in how to enter BIOS or UEFI settings.

Still Not Fixed?

If the PC shuts down when you put it to sleep, see Windows shuts down instead of sleeping.
If it never goes to sleep in the first place, see Windows 11 won't go to sleep.
Open Event Viewer > Windows Logs > System after a failed wake and look for errors at that time. The source name often points to the driver involved.

Frequently Asked Questions (FAQ)

Why won't my keyboard or mouse wake my PC?

Each device has a setting that lets it wake the computer. In Device Manager, open the keyboard or mouse Properties, go to the Power Management tab and tick Allow this device to wake the computer. Wireless receivers and some USB power-saving settings can also stop them from waking it.

My PC wakes up but the screen stays black. What should I do?

Press Windows key + Ctrl + Shift + B, which restarts the graphics driver. If the screen comes back, update the display driver. If it keeps happening, check the monitor's input and cable.

How do I force a stuck PC to turn back on after sleep?

Hold the power button for about 10 seconds until the PC turns off, wait a few seconds, then press it again. Any unsaved work will be lost, so use this only when nothing else responds.

Should I just turn off sleep?

It works around the problem but wastes power. Try the fixes first; if you need a workaround meanwhile, use Hibernate or shut down instead of Sleep.
