Fix Windows 10 Not Waking From Sleep Mode

If your Windows 10 PC goes to sleep but won’t wake up when you move the mouse or press a key, this guide walks you through the most common fixes. You’ll adjust power settings, update drivers, and check hardware settings to restore reliable wake behavior.

What You’ll Need

Administrator access to your Windows 10 PC
Your keyboard and mouse connected (wired or wireless)
Optional: a USB flash drive if you need to update a driver manually

Step-by-Step

Force a full restart. If the PC is stuck in a black screen, press and hold the physical power button for 10 seconds until it shuts off, then press it again to boot. This clears temporary glitches that often cause wake failures.
Check if it’s actually asleep or off. Look at the power LED on your tower or laptop. If it’s blinking, the PC is in sleep mode. If it’s off, it may have hibernated or shut down. Press the power button once to wake it.
Update your graphics and chipset drivers. Press Win + X and select Device Manager. Expand Display adapters, right-click your GPU, and choose Update driver â†’ Search automatically. Repeat for System devices (chipset) and Network adapters.
Enable wake timers. Go to Control Panel â†’ Power Options â†’ Change plan settings (next to your active plan) â†’ Change advanced power settings. Expand Sleep â†’ Allow wake timers and set both On battery and Plugged in to Enable. Click Apply and OK.
Allow your keyboard and mouse to wake the PC. Open Device Manager, expand Keyboards and Mice and other pointing devices. Right-click each device, choose Properties â†’ Power Management tab, and check Allow this device to wake the computer. Click OK.
Run the power troubleshooter. Go to Settings â†’ Update & Security â†’ Troubleshoot â†’ Additional troubleshooters â†’ Power â†’ Run the troubleshooter. Follow the prompts; it will often find and fix wake issues automatically.
Check the wake source. Open Command Prompt as administrator (type cmd in Start, right-click, Run as administrator) and run powercfg /lastwake. This shows what last woke the PC. If it says something like “Power Button”, that’s normal. If it lists a device, you may need to update or disable that device’s wake capability.
Disable Fast Startup. In Control Panel â†’ Power Options â†’ Choose what the power buttons do â†’ Change settings that are currently unavailable. Uncheck Turn on fast startup (recommended) and save changes. This is a common fix for wake failures after updates.
Update your BIOS/UEFI. Check your motherboard or laptop manufacturer’s support page for a BIOS update. Outdated BIOS firmware can cause sleep/wake problems. Follow their instructions exactly; a failed BIOS update can damage your system.
Check for Windows updates. Go to Settings â†’ Update & Security â†’ Windows Update â†’ Check for updates. Install any pending updates and restart.

Common Mistakes

Forgetting to check the device’s Power Management tab. Even if the setting looks enabled, some devices reset it after a driver update.
Disabling wake timers entirely. Some guides say to turn them off, but that can prevent scheduled tasks from waking the PC, which is fine, but it won’t fix a wake failure if the issue is driver-related.
Skipping the BIOS update. Many users try every Windows setting before checking for a BIOS fix, which is often the actual culprit.
Assuming the PC is asleep when it’s actually in hibernation. Hibernation saves to disk and requires a different wake process; press the power button, not a key.

Tips

Test after each step. Don’t apply all changes at once; test sleep/wake after each fix to isolate what worked.
Use the keyboard shortcut to sleep. Press Win + X â†’ U â†’ S to put the PC to sleep quickly for testing.
Keep your drivers updated regularly. Set Windows Update to automatically install driver updates, or check your manufacturer’s site monthly.
If using a wireless mouse, replace the batteries. A low battery can cause the receiver to not wake the PC.
Consider changing to “Hibernate” instead of “Sleep” for desktop PCs. Hibernation is more stable on some hardware and uses no power.

Troubleshooting

If you’ve gone through all the steps and the PC still won’t wake, try these advanced checks:

Check the event log. Open Event Viewer (type eventvwr in Start). Go to Windows Logs â†’ System and look for errors around the time you tried to wake. The source may indicate a driver or hardware issue.
Test with a different keyboard/mouse. If you have a spare wired USB keyboard, plug it in and see if it wakes the PC. If it does, your original device or its driver is the problem.
Disable USB selective suspend. In Power Options â†’ Advanced settings â†’ USB settings â†’ USB selective suspend setting, set it to Disabled for both battery and plugged in. This prevents the USB ports from cutting power to devices.
Run powercfg /energy in an admin Command Prompt. This generates a report in your user folder (e.g., C:\Users\YourName\energy-report.html) that lists power-related errors and warnings. Open it in a browser and look for “Wake Source” or “USB” entries.
If you have a desktop, try a different power outlet or surge protector. A failing PSU can cause wake failures.
As a last resort, reset your power plan. In Power Options, select Change plan settings â†’ Restore default settings for this plan. This resets all power settings without removing your files.

Frequently Asked Questions

Why does my PC go to sleep but the fans keep spinning?

This is normal for many systems; the PC is in a low-power state but the power supply may keep fans running. If it doesn’t wake, the issue is likely a driver or BIOS problem.

Will updating my graphics driver fix the wake issue?

Yes, in many cases. GPU drivers are a common cause of wake failures, especially after a Windows update. Always update your GPU driver first.

Can I disable sleep mode entirely to avoid the issue?

Yes, you can set your power plan to “Never” sleep, but that uses more electricity and may not be ideal for laptops. It’s a temporary workaround, not a fix.

Why does my mouse move but the screen stays black?

This often means the PC is awake but the display is not. Try pressing Win + P and then Enter to cycle display modes, or check your monitor’s input source.

Is it safe to press and hold the power button to force shutdown?

Yes, it’s safe as a last resort. It’s like pulling the plug, but modern Windows handles it without data loss in most cases. However, unsaved work may be lost.

Does Fast Startup cause wake problems?

Yes, Fast Startup can interfere with the wake process. Disabling it is one of the first things to try, and it’s harmless to disable.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
