How to Disable Sleep Mode on Windows 11

This practical guide walks through how to disable sleep mode on Windows 11, explains the main requirements, and highlights common issues that may appear along the way.

Disable Sleep mode in Settings.

First, launch the Windows Settings app by pressing Windows + i on your keyboard. Or you can right-click the Start button on the taskbar and select 'Settings' from the menu that appears.

In the Settings interface, click 'System' in the list on the left, then click 'Power & Battery'.

In the Power & Battery settings screen, steam to expand the 'Screen and Sleep' section. If your PC is battery-powered, such as a laptop or tablet, you'll see a total of 4 setup options. In case you use desktop, there will be only 2 options.

To keep your laptop or tablet awake even when not interacting and using power from the battery, switch the 'On battery power, put my device to sleep after' option to 'Never' '.

(Warning: If you set the 'On battery power, put my device to sleep after' option to 'Never', your PC will continue to work until it runs out of power, even without interaction, which can may cause significant battery drain).

To keep your PC awake when plugged in directly, look for the dropdown labeled 'On battery power, when plugged in, put my device to sleep' and set the option to 'Never' .

You can also prevent your PC from turning off the screen in all situations by setting the 'Turn off my screen after' option (or options for laptops) on the page to 'Never' .

Once that's set up, close the Settings app and your PC is now set up to work continuously without 'sleeping'. You can of course still put the device to sleep manually by pressing the power icon in the Start menu (select 'Sleep') or by using the dedicated Sleep key on the device if available.
