On our desktop or laptop computers, we install a variety of applications and add different components. We perform various tasks on our system, such as browsing, playing games, creating documents, etc.

There can be many reasons why a laptop is idle, such as hardware components or corrupted files, or processes running on the device.

While working, we faced some issues like those that PC suddenly shuts down, hangs, and others. Whatever the reason, but you can fix a random sleeping laptop by reading this post.

Explanation Why does my laptop keeps sleeping?

If your computer goes to sleep randomly, you probably have a misconfiguration in Windows that is causing this to happen. This happens quite often and many users are concerned with this simple problem. However, you need to find out which settings can be causing your computer to sleep randomly. Here I will discuss the various settings so that you don’t have to.

Sometimes old graphics can clutter your screen too, giving you the illusion that your Windows laptop is still sleeping. Some users have reported that this is the bug that was bothering them and it is quite easy to fix.

If you recently changed the theme in Windows, your screen saver settings may also change, which reduces the time-out period.

Lastly, there may also be some errors in the battery and related power settings. A bad battery can trigger the sleep setting. On the other hand, incorrectly configured power settings can activate Battery Saver when the device is idle, rendering the device inactive.

Check the sleep mode setting

When your computer does not go to sleep, check all the settings that can prevent the sleep state. Hardware, power options, and settings can affect the operation of the power and sleep buttons. If your PC has Windows, updates installed or installed applications need to be restarted, your PC may not suspend at all.

If you are working on a shared computer or a PC that is not yours, someone else may have changed the power options.

  • Open the Settings app. Click System, and then select Power On / off. On the far right, click Additional power settings. In the window that appears, click Choose to turn off the screen.
  • To the right of Put the computer to sleep, check the settings to make sure they are configured correctly. If your PC falls asleep too quickly or takes too long to fall asleep, this should be your first port of call.
  • Also, look at Advanced Power Settings. Click Change advanced power settings, then expand each section to check if each section can sleep (none of them should say “never”). For example, the “Shut down hard drive later” option should have a shorter time than your sleep setting.
  • By far the most common culprit is “USB Selective Suspend Settings”. If set to “Off”, any connected peripheral devices will continually ping your system to alert them that they are active, keeping you awake.

How to turn off when the laptop is off

After a certain period of inactivity, your computer becomes inactive, which can save battery power. If you decide that you need to save more or less, you can change the idle time of your laptop.

  • To change these settings, in the Control Panel, select Hardware and Sound.
  • You can change this as needed, so don’t feel like your computer should always be set up for these changes.
  • 2 In the Power Options section, click Change when the computer is idle.
  • The Edit Scheme Settings window appears.
  • 3 In the Edit Plan Settings window that appears, find the Put the computer to sleep field and click the field arrow in the Battery column.
  • From the drop-down list, select the second setting When the computer shuts down automatically.
  • A short interval saves battery power but can make your work difficult. So choose the settings according to your preferences.
  • 5 Click the Save Changes button to save the new settings.
  • You can adjust your computer’s brightness, screen off, and sleep settings through PC Settings.

Press Win + I from the desktop or Start screen and click Change PC settings → PC and devices → Power and sleep. Use the Sleep setting to control whether your device automatically adjusts the screen brightness and how long it takes before the screen turns off or the PC goes to sleep.
