You can work on your PC in various ways. Some people use it from another place when needed via a remote connection. But when that computer goes into sleep mode, you won’t be able to connect to it, when your network has no means to awake the machine. Due to this and many other reasons, users would like to know how to disable sleep mode in Windows. In this guide, we will explain multiple options to disable this mode in Windows 10, 8, and Windows 7.

Prevent automatic sleep mode activation on your PC

Let’s begin with the easiest method to do it – disable sleep function by changing Settings in Windows. In order to get to the menu we are looking for, you need to click on the Start button and find an icon with a small gear (or you can just press Win+I). This will bring you to the Windows Settings menu. Once there click on the System menu and find a subsection called «Power & sleep.» Set Sleep parameter to «Never.»

Due to different designs in Windows 10 and earlier versions of Windows this particular method works only in Windows 10. This is why we are going to show you another way to disable sleep activation through the Control Panel, which remains unchanged in all latest version of Windows. So you can use it no matter what operating system you have: Windows 10/8/7 or even XP!

Turn off sleep mode in the control panel

Before the release of Windows 10, Control Panel has always been the main customization hub with all settings needed for system tuning. Now we will explain how to prevent sleep mode activation on your desktop or laptop with Windows 10/8/7/XP. Press Win+R and type control in the small window that will appear. Click Ok or hit Enter.

This will bring you to the Control Panel where you need to find a menu called «Power Options.» In case you can see it, switch the «View by» option to «Large Icons» and you will get this picture:

Control Panel where you need to find a menu called «Power Options.»

Alternative solution: press Win+R and type powercfg.cpl in the small window that will appear. This shortcut action will get you to the Power Options menu skipping the previous step.

On the left sidebar, you will see a line «Change when the computer sleeps» - click it. Alternatively, you can click on «Change plan settings» for the selected preferred plan.

Change when the computer sleeps

In the next menu, you just need to select «Never» for the setting «Put computer to sleep.» In addition to that, if you are annoyed by the fact that your display also goes into sleep mode, in this menu you can prevent «monitor sleeping» by selecting «Turn off display» - «Never.»

Select «Never» for the setting «Put computer to sleep.»

After doing so, your computer will never automatically switch to the sleep mode unless you have additional alternative settings and conditions activated (we will talk about this later in this article).

Disable sleep mode by customizing a power plan

Sometimes conflicts may occur due to different settings and parameters that contradict each other in your current power plan. For instance, when in the power plan you set sleep mode activation to «Never» and then turned off sleep mode completely, both parameters may have equal priority. It all depends on the chipset driver that controls the operation of power plans. Sometimes your PC can still «fall asleep» even with both parameters set to «Never» - this happens when you have wrong powercfg settings, but we will talk about it later.

Now we need to customize a power plan we will be using and change some settings in it. Go to the Power Options menu, click «Change plan settings» - «Change advanced power settings.»

Disable sleep mode by customizing a power plan

Look for the «Sleep» submenu. Settings such as «Sleep after» and «Hibernate after» activate Sleep and Hibernate modes accordingly after a period of inactivity. «Allow wake timers» is there to awake your computer after certain actions. In this subsection, you need to change the setting for «Sleep after» and «Hibernate after» to «Never.» This is how you disable sleep mode in Windows 10/8/7.

Change the setting for «Sleep after» and «Hibernate after» to «Never.»

Disable Sleep mode using powercfg

For more delicate customization of power plans, you can use the powercfg command. It allows you to run a full power system diagnostics and detect the most power-hungry applications as well as set specific triggers for your computer to wake up from sleep/hibernate and so on. All commands must be entered in the Command Prompt run as administrator (press Win+X and select this option). If you need help, just type «powercfg /?».

Here are the main commands you will be using:

  • Powercfg /energy – analyzes the system’s energy consumption and detects errors and warnings. After finishing, you will see this screen (and it will also create a report in the System32 folder):
Disable Sleep mode using powercfg
  • Powercfg /waketimers – shows active awake timer we have mentioned earlier.

You can also set time to put your PC to sleep:

  • powercfg -x -standby-timeout-ac 0 (0 – would be «Never,» 15 would be equal to 15 minutes).
  • standby – sleep mode when no actions are performed on the computer for a period.
  • monitor – turn off your monitor.
  • hibernate – activation of the hibernate mode.

We would like to point out that it is important to know your chipset drivers such Intel Management Engine and others as they can also solve your problems with automatic sleep mode activation and other energy options issues. We recommend using power plans recommended by the manufacturer of your device. According to our statistics, it can really solve most problems in this regard. This concludes our guide about disabling sleep mode in Windows 10/8/7. We hope after reading this, you will have one problem less!
