PC Monitor Won’t Sleep Automatically (Windows 10) – FIXED

Windows 10 has a built-in feature where, if your system idle for too long, it will start putting some components to sleep. This sleep process starts with the screen locking on inactivity, then the monitor turns off ie, goes into sleep, and ends with the whole system going into sleep mode.

Automatic sleep monitoring

Users can choose when some parts of their system go to sleep. Both the display and the system can be set to go to sleep after a period of inactivity that a user can select. The setting is implemented according to each power plan and on the basis of power state ie, if the system is running on battery or is plugged in.

Monitoring sleep mode, defined

The sleep function of the monitor is automatic. If a user never changes it, it will use the default setting and go to sleep accordingly. The default settings usually take a short time so your monitor is likely to sleep in 2-5 minutes.

Non-automatic sleep monitoring (solutions)

If Windows 10 does not put the monitor to sleep, there may be several reasons behind it. Try the solutions below to find out what is preventing your monitor from going to sleep.

1. Check power plan options

It is possible that your monitor will not sleep because it is not the time to go to sleep. The timeout may be set too long and you may expect the monitor to go into sleep faster.

  1. Open File Explorer.
  2. Enter the following in the place bar and tap Enter.
Control PanelHardware and SoundPower Options
  1. In the left column, select ‘Choose when to cancel the show’.
  2. Open the drop down under Battery and Plugged in for Turn off the display and select a shorter time.
  3. Click Save changes.

2. View active / running apps

Part apps will prevent Windows 10 from hibernating the display and the system even if the user has idle. Common examples of these types of apps are media players, torrent messengers, and download managers.

Take a look at what apps are running on your system and if any of them may be responsible for preventing sleep deprivation for the show.

Any ongoing an action or script can also prevent the monitor from going to sleep.

3. System sleep blockers

While system sleep and sleep monitoring are two different things, it is possible that an app that prevents your system from falling asleep is also blocking the monitor from going to sleep. To find out which app is blocking sleep, follow this step.

  1. Open Promptly forward with administrative rights.
  2. Run this command: powercfg /requests.
  3. The list of apps that the answers are command preventing the system from sleeping.

4. Force sleep monitoring

You can turn the monitor to sleep by setting the power button to turn off the display.

  1. Open File Explorer.
  2. Enter this in the place bar Control PanelHardware and SoundPower Options and tap on Enter.
  3. In the left-hand column, click Select what closing the cover will do.
  4. Open the dropdowns for When I press the power button and select Turn off the display for both Battery and plug-in options.
  5. Click on the power button to put the monitor to sleep.

5. Remove other tools

Some devices connected to your system e..g. an external hard form can prevent the system from falling asleep. If your hardware has its own power source, it is more likely to prevent sleep on your monitor or system. Disconnect devices and see if the system is going to sleep.

6. Turn off optional USB lock

Please disable optional USB. It is intended to conserve power by turning off unused USB ports but it can interfere with sleep activity.

  1. Open File Explorer.
  2. Enter this in the place bar Control PanelHardware and SoundPower Options and tap on Enter.
  3. Click Change plan settings next to the plan that is currently operational.
  4. Click Change advanced settings.
  5. In the window that opens, expand USB settings.
  6. set out Optional USB suspend to disable.
  7. Restart the system for good measure.


The monitor can be turned off manually but it is clear that the set-up sleep function is better as it works automatically. If your monitor is not sleeping, it is very likely that it is being blocked by an app. Go through your currently running apps, and you’ll be able to find out which one is blocking the system’s sleep.
