How to Fix Windows 11 Screen Timeout Not Working: Effective Troubleshooting Steps

Windows 11 screen timeout controls how long your display stays on before turning off automatically. Sometimes, this feature may stop working as expected, causing your screen to stay on indefinitely or turn off too soon. Fixing this issue helps save battery life and protects your screen from burn-in.

In this guide, we will walk you through simple and effective steps to troubleshoot the screen timeout problem on Windows 11. These instructions are designed to be easy to follow, even if you are not very tech-savvy.

By the end, you should have a clear idea of what may be causing the timeout issue and how to fix it. Let’s start with a few quick checks before diving into the troubleshooting steps.

Follow along carefully, and don’t hesitate to try multiple solutions if the first one doesn’t work for you.

Quick Note: Prerequisites and Basic Checks

Check your power source: Screen timeout settings can differ between battery and plugged-in modes. Ensure you know which mode you’re troubleshooting for.
Update Windows 11: Sometimes bugs are fixed in updates. Make sure your system is up to date by going to Settings > Windows Update.
Restart your PC: Many problems can be resolved with a simple restart. Try this before moving to more complex steps.
Close active apps: Some apps or processes may prevent the screen from turning off. Close unnecessary programs before testing timeout again.

Step 1: Verify and Adjust Screen Timeout Settings

This is the most straightforward place to start. Sometimes, timeout settings are accidentally set to “Never” or a very long duration.

Click on the Start button and select Settings (gear icon).
Go to System > Power & battery.
Under the Screen and sleep section, check the timeout durations for both “On battery power” and “When plugged in.”
Set appropriate timeouts, such as 5 minutes for battery and 10 minutes when plugged in.
Test if the screen now turns off after the set time.

Why this matters: Incorrect timeout values are the most common cause of the issue. Ensuring they are set correctly is the first troubleshooting step.

Step 2: Disable “Keep my screen on” Features

Windows 11 includes some features that prevent the screen from turning off, such as certain power and display settings.

In Settings, go to System > Power & battery.
Click on Screen and sleep to expand options.
Look for any options related to keeping the screen on or preventing sleep, such as “When plugged in, keep my screen on” or similar.
Make sure these options are turned off.
Additionally, check the Focus assist settings as sometimes notifications can keep the screen awake.

Why this matters: These settings override screen timeout and can cause the display to stay on indefinitely.

Step 3: Check for Active Apps or Background Processes

Some applications prevent screen timeout, especially media players or remote desktop tools.

Open Task Manager by pressing Ctrl + Shift + Esc.
Look under the Processes tab for apps such as video players, communication tools (Zoom, Teams), or system utilities that may block timeout.
Try closing these apps one at a time and see if the timeout works.

Why this matters: Certain apps keep the screen awake intentionally, so identifying and closing them helps restore normal behavior.

Step 4: Run the Power Troubleshooter

Windows has a built-in troubleshooter that automatically detects and fixes power-related issues.

Open Settings and go to System > Troubleshoot > Other troubleshooters.
Find Power in the list and click Run.
Follow the on-screen instructions to let Windows diagnose and fix any problems.

Why this matters: The troubleshooter can catch hidden or technical issues that manual steps may miss.

Step 5: Adjust Screen Timeout via Registry (Advanced)

If the problem persists, sometimes registry settings can interfere with timeout behavior. Editing the registry should be done carefully.

Press Windows + R, type regedit, and press Enter to open the Registry Editor.
Navigate to the following key:
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPowerPowerSettings7516b95f-f776-4464-8c53-06167f40cc993c0bc021-c8a8-4e07-a973-6b14cbcb2b7e
Double-click the Attributes value and change it from 1 to 0 to make the setting visible in Power Options.
Close Registry Editor and open Control Panel > Power Options > Change plan settings for your active plan.
Click Change advanced power settings.
Look for the newly visible timeout options and adjust them accordingly.
Restart your PC and check if the timeout now works.

Why this matters: Some timeout settings are hidden by default and can only be changed through the registry or advanced power settings.

Step 6: Update or Reinstall Display Drivers

Outdated or corrupted display drivers can interfere with screen timeout.

Right-click the Start button and select Device Manager.
Expand Display adapters.
Right-click your display adapter and select Update driver.
Choose Search automatically for drivers and follow prompts.
If updating doesn’t help, you can try uninstalling the driver and restarting your PC. Windows will reinstall the default driver automatically.

Why this matters: Proper display drivers ensure your screen communicates correctly with Windows power settings.
