How to disable sleep mode in Windows 11 and 10 (and when you should not)

Sleep mode is the low power state Windows enters after a set idle time. You can disable it safely: set Make my device sleep after to Never for both plugged in and on battery, and the PC stays awake until you choose otherwise. The only price is the power the PC uses while idle.

What sleep mode is, and what people confuse it with

Sleep is one of four things that can happen to an idle PC, and each has its own setting. Sleep keeps your open apps in memory and keeps that memory powered, so the PC wakes in a few seconds where you left it. While it sleeps, it does no work: downloads, uploads and scheduled jobs stop.

The reader in the question above sees exactly this: the PC sleeps when left alone for a while. That is the Make my device sleep after timer. Turning the screen off is a different timer, and hibernation is a third one.

What you gain and what it costs

Disabling sleep does not make Windows faster. It only decides whether the PC keeps working when nobody touches it. Microsoft lowered the default sleep timers in Windows 11 to cut idle power use, which tells you where the cost is.

Who should disable sleep and who should keep it

For a desktop that runs jobs overnight, Never is a reasonable choice. For a laptop that lives on battery, a longer timer is usually better than no timer, because a forgotten laptop with sleep off empties its battery.

How to disable sleep mode in Windows

Methods go from the simplest setting to the most thorough. Method 1 is enough for most readers. Method 2 covers the hibernate timer and Windows 7, Method 3 does it with one command, Method 4 handles laptop lids and power buttons, and Method 5 is for a PC that sleeps anyway. Windows 10 steps are given too, although Windows 10 left support on 14 October 2025.

Method 1. Set Make my device sleep after to Never in Settings

2 minutesNo riskEveryone on Windows 11 or Windows 10. This is the setting Microsoft documents for the sleep timer.

Windows starts sleep only from this idle timer. With the timer at Never, idle time no longer sends the PC to sleep, while Sleep in the Start menu still works when you want it.

Windows 11:

1. Press Win + I to open Settings.
2. Select System, then Power & battery. On a PC without a battery the page is called Power.
3. Expand Screen, sleep & hibernate timeouts.
4. Set Make my device sleep after to Never for Plugged in.
5. On a laptop, set it to Never for On battery too, or to a long time if you want some battery protection.

Windows 10: open Settings > System > Power & sleep. Under Sleep, set When plugged in, PC goes to sleep after to Never, and do the same for the battery line on a laptop.

Method 2. Change the power plan in Control Panel (also Windows 7)

4 minutesNo riskYou are on Windows 7, Settings shows no sleep line, or the PC hibernates after you turned sleep off.

Control Panel edits the active power plan directly and shows settings that Settings hides, such as Hibernate after. A PC with sleep at Never can still hibernate on its own timer, so this method turns off both.

1. Select the taskbar search box, type control panel and open it.
2. Select Hardware and Sound (or System and Security), then Power Options.
3. Next to the selected plan, select Change plan settings.
4. Set Put the computer to sleep to Never and select Save changes.
5. Select Change advanced power settings, expand Sleep, then Hibernate after, and set it to Never (or 0).
6. Select OK.

Method 3. Turn off the sleep timer with powercfg in Command Prompt or PowerShell

2 minutesNo riskYou prefer a command, you set up several PCs, or Settings is locked or missing.

Microsoft documents powercfg /change as the way to modify a timer in the current power scheme, with the value in minutes. It sets the same timers as Methods 1 and 2, so the result shows up there too.

1. Type cmd or powershell in the taskbar search box.
2. Select Run as administrator and confirm with Yes. Step by step: How to run a program as administrator or in compatibility mode.
3. Run the commands below. The first line is for plugged in, the second for battery.
4. Open Settings as in Method 1 and check that the sleep line now reads Never.

powercfg /change standby-timeout-ac 0
powercfg /change standby-timeout-dc 0
powercfg /change hibernate-timeout-ac 0
powercfg /change hibernate-timeout-dc 0

Microsoft's page gives the value in minutes and does not spell out what 0 means. In Settings a 0 shows as Never, which is why step 4 checks it there.

Method 4. Stop the laptop from sleeping when you close the lid or press the power button

3 minutesLow riskA laptop sleeps the moment you close the lid, or a desktop sleeps when someone presses the power button.

Lid and button actions do not use the idle timer, so Never in Methods 1 to 3 does not touch them. Microsoft keeps these choices in Control Panel under Choose what closing the lid does.

1. Open Control Panel and go to Power Options.
2. Select Choose what closing the lid does (on a desktop, Choose what the power buttons do).
3. For When I close the lid, choose Do nothing under Plugged in.
4. Change When I press the power button if you want that to stop sending the PC to sleep too.
5. Select Save changes.

Method 5. If the PC still sleeps: find the setting or app that sends it to sleep

10 minutesNo riskEvery sleep setting reads Never and the PC still goes to sleep or hibernates.

Each power plan keeps its own timers, so a plan switch brings the old timer back. Microsoft's powercfg tool reports which plan is active and what really happened during each sleep, which replaces guessing.

1. Check that only the screen did not go off. If the fans run and a key brings the picture back at once, the PC did not sleep.
2. Open an administrator Command Prompt and run powercfg /getactivescheme to see the active plan.
3. Run powercfg /list. If the active plan is not the one you changed, repeat Method 1 or Method 3 now.
4. Run powercfg /systemsleepdiagnostics. It saves an HTML report of the last three days in the current folder.
5. Open the report and look at when the PC went to sleep while you were away.
6. If the PC wakes up on its own instead, run powercfg /lastwake and powercfg /waketimers to see what woke it.

powercfg /getactivescheme
powercfg /list
powercfg /systemsleepdiagnostics
powercfg /lastwake

How to turn sleep mode back on

Every change in this guide is a normal setting, so undoing it is the same steps with a number instead of Never. Pick the timer you want rather than copying the old default: 30 minutes plugged in is common for a desktop.

Myths about sleep mode

Most copies of this guide on the web repeat the same tips. Here is what Microsoft's own pages support.

• "powercfg -h off disables sleep." It disables hibernation. Microsoft's powercfg page lists /hibernate off as the switch that turns off the hibernate feature, and sleep keeps its timer.
• "Turning off sleep makes the PC faster." Sleep only acts when the PC is idle. Nothing in Microsoft's documentation links it to speed while you work.
• "You need the registry to disable sleep." The timer has a supported switch in Settings and in powercfg. Registry values passed around online change other things, such as modern standby, and we could not confirm them in Microsoft's documentation.
• "Sleep set to Never keeps the screen on." The screen has its own timer. Set Turn my screen off after if you want the display on too.
• "Sleep damages the PC, so turn it off." Sleep is a standard power state. Microsoft recommends shorter sleep timers, not longer ones, to save energy.

Frequently asked questions

How do I disable sleep mode in Windows 7?

Use Control Panel, because Windows 7 has no Settings app for this. Open Control Panel > Hardware and Sound > Power Options, select Change plan settings next to your plan, set Put the computer to sleep to Never for each column and select Save changes. Then open Change advanced power settings and set Sleep > Hibernate after to Never. The powercfg /change standby-timeout-ac 0 command also works there. Windows 7 no longer receives security updates, so plan a move to a supported version.

Can I disable sleep mode in Windows 11 with the registry?

You can, but you do not need to, and we do not recommend it. The sleep timer has supported switches in Settings and in the powercfg command, which Microsoft documents. The registry values that circulate online, such as CsEnabled under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power or an Attributes value under PowerSettings, do other things, such as turning off modern standby or showing hidden power options. We could not confirm their effects in Microsoft's documentation. Use Method 1 or Method 3.

Is it bad to turn off sleep mode on my computer?

No. It is a normal setting and nothing breaks. The cost is power: the PC draws idle power for as long as it is on, and a laptop on battery runs down. Microsoft lowered the default sleep timers in Windows 11 to reduce idle energy use, so on a laptop a longer timer on battery is often the better choice. On a desktop that runs downloads or backups overnight, Never is fine, especially if the screen still turns off by itself.

Why does my PC still go to sleep after I set it to Never?

There are four usual reasons. Only one column was changed, for example plugged in but not battery. The screen turned off but the PC did not sleep. The laptop sleeps from the lid or the power button, which have their own setting. Or another power plan became active, with its own timers. Method 5 shows how to check: powercfg /getactivescheme names the active plan, and powercfg /systemsleepdiagnostics reports when the PC really slept. On a work PC, a policy may also reset the timer.

What is the difference between sleep and hibernate?

Sleep keeps your open work in memory and keeps that memory powered, so the PC wakes in a few seconds. Hibernate writes the contents of memory to the disk and powers off, so it uses no power but takes longer to resume. They have separate timers. Setting sleep to Never does not stop hibernation, which has its own Hibernate after timer in Control Panel and its own hibernate-timeout value in powercfg. powercfg /hibernate off removes hibernation entirely and leaves sleep as it was.

How do I stop the screen from turning off as well?

Change the screen timer, which is separate from sleep. In Windows 11 open Settings > System > Power & battery > Screen, sleep & hibernate timeouts and set Turn my screen off after to Never. In Windows 10 the line is under Settings > System > Power & sleep. The command is powercfg /change monitor-timeout-ac 0. Think before you do it: a screen that stays on all night uses power and shows whatever is open to anyone passing by. A screen timer with sleep off is usually enough.

What are the default sleep times in Windows 11?

Microsoft changed them to save energy. On PCs with S3 sleep the defaults are now 15 minutes plugged in and 10 minutes on battery, down from 30 and 15. On modern standby PCs, which are many newer laptops, they are 5 minutes plugged in and 3 minutes on battery, down from 10 and 4. Microsoft lists the screen timers too: 5 minutes plugged in and 3 on battery. Your PC maker may ship other values, and changing the setting yourself overrides them.

Can I keep my PC awake only during a download, without changing settings?

Windows has no built-in switch for a one-time stay-awake, but many apps ask Windows to stay awake while they work, through a power request. Microsoft documents powercfg /requests, which lists the apps and drivers that are currently keeping the PC awake. If your download app is not listed, it does not ask, and the PC will sleep on its timer. In that case set sleep to Never for the download and put the timer back afterwards with the steps in the undo table.

Does disabling sleep mode use a lot of electricity?

It depends on the PC, and Microsoft gives no figure for it. A PC that stays awake draws its idle power all the time, instead of the very low power of sleep. A desktop with a strong graphics card draws more at idle than a small laptop. If power matters, keep sleep on and set a longer timer, or let the screen turn off. Microsoft's own advice for saving power is shorter screen and sleep timers and the Best power efficiency power mode: Change the power mode.
