How to Fix Modern Standby Not Working Issues on Windows 11: Complete Troubleshooting Guide

Modern Standby is a feature in Windows 11 that allows your device to stay connected to the internet while in a low-power state. This helps you receive notifications and updates quickly without fully waking your computer. However, sometimes Modern Standby might stop working properly, causing issues like your device not waking up or staying connected during sleep.

If you’re experiencing problems with Modern Standby on your Windows 11 PC, this guide will help you troubleshoot and fix the issue step-by-step. The instructions are simple and designed for users of all levels.

We will start with the easiest checks and move toward more advanced solutions. By following this guide, you can restore Modern Standby functionality and improve your device’s power management.

Let’s begin by understanding some quick notes and prerequisites before diving into the troubleshooting steps.

Quick Note: Prerequisites and Initial Checks

Before you start troubleshooting, make sure to check the following:

  • Confirm your device supports Modern Standby: Not all PCs support this feature. You can check by running the command powercfg /a in Command Prompt. If you see “Standby (S0 Low Power Idle)” listed, your device supports Modern Standby.
  • Keep your Windows 11 updated: Updates often fix bugs and improve system features. Go to Settings > Windows Update and install any pending updates.
  • Check your device drivers: Outdated or incompatible drivers may cause power management problems. Focus on network, chipset, and display drivers.
  • Ensure your device has adequate battery charge: Some power features may not work if the battery is too low or if the device is plugged in incorrectly.

Step 1: Restart Your PC

Restarting your computer is the simplest way to fix many temporary glitches. It refreshes system processes and may resolve minor conflicts affecting Modern Standby.

To restart:

  1. Click the Start button.
  2. Select Power and then Restart.
  3. Wait for your PC to reboot fully.

After restarting, check if Modern Standby behavior has improved.

Step 2: Run the Power Troubleshooter

Windows 11 has built-in troubleshooters that can detect and fix common power-related issues automatically.

To run the Power Troubleshooter:

  1. Open Settings by pressing Win + I.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Power and click Run.
  4. Follow the on-screen instructions to complete the process.

This tool will attempt to identify problems related to sleep and power management and apply fixes.

Step 3: Check and Update Device Drivers

Modern Standby relies on hardware components working correctly. Outdated or incompatible drivers can cause failures.

To update drivers:

  1. Press Win + X and select Device Manager.
  2. Expand categories like Network adapters, System devices, and Display adapters.
  3. Right-click each device and choose Update driver.
  4. Select Search automatically for drivers and follow prompts.

If Windows doesn’t find any new drivers, visit your PC manufacturer’s website to download and install the latest versions manually.

Step 4: Disable and Re-enable Modern Standby

Sometimes toggling Modern Standby off and on can fix issues caused by corrupted settings.

To do this, you will need to modify the registry. Be careful and follow these steps exactly.

  1. Press Win + R, type regedit, and press Enter.
  2. Navigate to the following path:
    HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPower
  3. Look for a DWORD value named CsEnabled.
  4. Double-click it and change the value from 1 to 0 to disable Modern Standby.
  5. Restart your PC.
  6. After reboot, repeat the steps and change CsEnabled back to 1 to re-enable Modern Standby.
  7. Restart again and check if the issue is resolved.

Why is this important? The CsEnabled registry key controls whether Modern Standby is active. Resetting it can clear corrupt configurations.

Step 5: Adjust Power Plan Settings

Incorrect power plan settings can interfere with Modern Standby. Resetting them to default can help.

To reset power plans:

  1. Open Command Prompt as Administrator. You can do this by typing cmd in Start, right-clicking, and selecting Run as administrator.
  2. Type the following command and press Enter:
    powercfg -restoredefaultschemes
  3. This resets all power plans to their default settings.
  4. Restart your PC and test Modern Standby again.

Step 6: Update BIOS/UEFI Firmware

Your system firmware (BIOS or UEFI) controls hardware-level power features. An outdated or buggy firmware can cause Modern Standby issues.

To update BIOS/UEFI:

  • Visit your PC or motherboard manufacturer’s official website.
  • Locate the support or downloads section and find the latest BIOS/UEFI firmware for your model.
  • Follow the manufacturer’s instructions carefully to download and install the update.

Note: Updating firmware is an advanced step. Make sure your device is plugged into power, and do not interrupt the update process.

Step 7: Disable Fast Startup Temporarily

Fast Startup can sometimes conflict with Modern Standby, causing sleep or wake problems.

To disable Fast Startup:

  1. Open Control Panel and go to Power Options.
  2. Click Choose what the power buttons do on the left side.
  3. Click Change settings that are currently unavailable.
  4. Uncheck the box for Turn on fast startup (recommended).
  5. Click Save changes and restart your PC.

Test if Modern Standby works better without Fast Startup enabled.

Advanced Option: Use Windows Power Troubleshooting Logs

If the above steps do not fix the issue, you can dig deeper by checking the Windows Event Viewer for power-related errors.

To view logs:

  1. Press Win + X and select Event Viewer.
  2. Expand Windows Logs > System.
  3. Look for errors or warnings related to Power-Troubleshooter or Kernel-Power.
  4. Note down any error codes or messages and search for specific fixes online or on Microsoft’s support site.
