Where is the power button setting in Windows 11?

The setting that controls the physical power button and the laptop lid lives in Control Panel, not the Settings app. Open Control Panel, go to Hardware and Sound, then Power Options, and click Choose what the power buttons do on the left. From there you can set what pressing the power button, pressing a sleep button, and closing the lid each do — Do nothing, Sleep, Hibernate, Shut down or Turn off the display.

How do I add Hibernate to the Start menu power button in Windows 11?

Hibernate is hidden by default. Open Terminal or Command Prompt as an administrator and run powercfg /hibernate on. Then open Control Panel, go to Hardware and Sound, then Power Options, click Choose what the power buttons do, click Change settings that are currently unavailable, tick the Hibernate box under Shutdown settings, and click Save changes. Hibernate then appears in the Start menu power control and the Win + X menu.

What is fast startup and should I turn it off?

Fast startup is a Windows feature that saves part of the system state to disk on shutdown so the PC boots faster next time. It is a hybrid of a full shutdown and hibernation, and it only appears when hibernation is enabled. It is fine to leave on for most people, but turning it off can help if you dual-boot, use certain disk-encryption tools, or find that a shutdown does not fully clear a problem. You control it under Shutdown settings in Choose what the power buttons do.

Why does the Start menu power button not show Hibernate?

The Start menu power control in Windows 11 shows Sleep, Shut down and Restart by default. Hibernate only appears once you enable hibernation with powercfg /hibernate on and then tick the Hibernate box under Shutdown settings in Choose what the power buttons do. If your device does not support hibernation, or the setting is blocked by policy, the option will not appear at all.

Change What the Power Button Does in Windows 11

"Power button" means two different things in Windows 11, and mixing them up is where most confusion starts. There is the physical button on your PC case or laptop (and, on a laptop, the lid you close), and there is the small power icon on the Start menu that pops up Sleep, Shut down and Restart. They are configured in different places, and this guide covers all of it: setting the physical button and lid action, adding Hibernate to the Start menu, and deciding what to do about fast startup.

If you just want to stop your laptop sleeping when you close the lid, or make a short press of the power button shut the machine down instead of sleeping, skip to setting the physical button and lid. If you want Hibernate back in your menus, jump to adding Hibernate.

Click Start, and the power icon sits in the bottom-right corner of the Start menu (next to your account picture). Selecting it opens a small pop-up. Out of the box in Windows 11 that pop-up offers three actions:

Sleep — saves your open apps to memory and drops the PC into a very low-power state. Press a key or the power button and you are back in a second or two. A desktop still sips a little power at the wall while it sleeps.
Shut down — closes everything and powers the machine off. With fast startup on (see below), this is a hybrid shutdown rather than a full cold one.
Restart — a full reboot that always clears memory, which is why "restart, don't shut down" is the standard advice for applying updates or clearing a glitch.

A fourth action, Hibernate, is hidden by default. Unlike Windows Vista and Windows 7 — where the Start menu had one round button whose single action you configured — Windows 11 does not let you reassign the Start menu power icon to "always shut down". Instead you add or remove the actions the menu offers. Adding Hibernate is the main thing people want here, so that is next.

Add Hibernate to the Start menu (and the Win + X menu)

Hibernate writes the entire contents of memory to disk and then powers the PC off completely, so it draws no power at all, yet your open windows come back when you switch on again. It is the best of both worlds on a laptop. It is switched off by default in Windows 11, so you enable it in two stages.

Step 1 — turn hibernation on

Right-click the Start button and choose Terminal (Admin). (On older builds this may read Windows PowerShell (Admin) or Command Prompt (Admin) — any of them works.) Approve the User Account Control prompt.
Type the following and press Enter:
```
powercfg /hibernate on
```

The older powercfg -h on form does exactly the same thing — Microsoft Learn's powercfg command-line reference lists the switch as /hibernate or /H, taking on or off. This creates the hibernation file (hiberfil.sys) and makes the feature available. Nothing visible happens yet — you still have to switch the menu entry on.

Step 2 — show Hibernate in the menus

Open Control Panel (press Start, type Control Panel, and open it).
Go to Hardware and Sound → Power Options. If Control Panel is set to the small or large icon view, click Power Options directly.
On the left, click Choose what the power buttons do.
Click the blue Change settings that are currently unavailable link near the top. This unlocks the grayed-out checkboxes lower down (you may see another UAC prompt).
Under Shutdown settings, tick Hibernate.
Click Save changes.

Open the Start menu power control now and Hibernate appears alongside Sleep, Shut down and Restart. It also shows up on the Win + X menu under Shut down or sign out — both routes are the ones Microsoft Support's "Shut down, sleep, or hibernate your PC" page gives once the checkbox is ticked.

Don't see the Hibernate checkbox?

If the box is missing even after running powercfg /hibernate on, your device may not support hibernation (some modern laptops that use Modern Standby ship without it), or it may be blocked by a company policy. Run powercfg /availablesleepstates in the same admin Terminal to see which states your hardware actually supports — Microsoft Learn notes that this switch also attempts to report why a sleep state is unavailable.

Set what the physical power button and lid do

This is the setting most people are really after: making a press of the power button, or closing the laptop lid, do something other than the default. It lives in the same Control Panel page you just used.

Open Control Panel → Hardware and Sound → Power Options.
Click Choose what the power buttons do on the left. The full path, if you like to type it, is:
```
Control Panel\Hardware and Sound\Power Options\System Settings
```
Use the drop-downs to set each action:
- When I press the power button — Do nothing, Sleep, Hibernate, Shut down or Turn off the display.
- When I press the sleep button — for keyboards or PCs that have a dedicated sleep key.
- When I close the lid — laptops only; the same choices, commonly set to Do nothing when you use an external monitor with the lid shut.
Click Save changes. The new behaviour takes effect immediately — no restart needed.

On a laptop? You'll see two columns

Portable machines show each action twice — On battery and Plugged in — so you can give the button and lid different behaviour depending on power source. A common setup is Sleep on battery and Do nothing (lid) plus Shut down (button) when plugged into a dock. Set both columns if you want the same result everywhere.

Which action should you choose?

Shut down — powers off completely; nothing stays open. Best if you want "off" to mean off, or share a family desktop.
Hibernate — saves your session to disk and powers down; zero power draw, and your windows return. Ideal for laptops you carry between sessions.
Sleep — near-instant resume, but stays in a low-power state. Fine for stepping away briefly.
Turn off the display — just blanks the screen while the PC keeps running; handy for a media PC.
Do nothing — most useful for the lid, so a docked laptop keeps running with the lid shut.

Fast startup, and why it hides under the same page

On the same Choose what the power buttons do screen, under Shutdown settings, you will find Turn on fast startup (recommended). Fast startup is a hybrid of a full shutdown and hibernation: when you shut down, Windows saves the core system state to disk so the next boot is quicker. Because it relies on hibernation, the checkbox only appears once hibernation is enabled — which is why turning Hibernate on above may make this option show up too.

Open Control Panel → Hardware and Sound → Power Options → Choose what the power buttons do.
Click Change settings that are currently unavailable.
Under Shutdown settings, tick or clear Turn on fast startup (recommended).
Click Save changes.

When to switch fast startup off

Leave it on for most single-OS desktops and laptops. Turn it off if you dual-boot another operating system (fast startup can lock the Windows drive), if certain disk-encryption tools misbehave, or if a "shut down and start again" does not seem to fully clear a hardware or driver problem — in that case a true full shutdown, or a Restart, is what actually resets the machine. The trade-off is a slightly longer boot.

What the Settings app does (and doesn't) cover

You might expect all of this to live in the modern Settings app, but only part of it does. Open Settings → System → Power (labelled Power & battery on laptops) and you will find the Screen and sleep timers documented on Microsoft Support's Windows 11 power settings page — how long before the display turns off and how long before the PC sleeps — plus power mode and, on laptops, battery saver. What you will not find there is the power-button and lid action: those still open the classic Control Panel page. It is the one part of Windows power management Microsoft has never moved across, so any guide that tells you to reassign the power button "in Settings" is pointing you at the wrong place.

If you are still on Windows 10

The good news is that the important part is nearly identical. In Windows 10 the route is the same — Control Panel → Hardware and Sound → Power Options → Choose what the power buttons do — with the same power-button, sleep-button and lid drop-downs and the same fast startup checkbox under Shutdown settings. The one visible difference is the Start menu: in Windows 10 the power icon is on the left edge of the Start menu rather than the bottom-right corner, but it offers the same Sleep, Shut down and Restart actions, with Hibernate added the same way via powercfg /hibernate on and the Shutdown-settings checkbox.

From the archive

This topic goes back a long way on windows-now.com. It was first covered in the windows-now.com era by Kristan Kenney, writing about the round Start menu power button in Windows Vista and how to point it at Shut down, Sleep or Hibernate. The Control Panel page has barely changed since — you can read the original archived post for the Vista-era version of these same Power Options.

Wrapping up

Windows 11 splits "the power button" into the physical button and lid (configured in Control Panel's Power Options) and the Start menu power control (whose Sleep, Shut down and Restart you extend with Hibernate rather than reassign). Once you know that the button and lid live under Choose what the power buttons do — and that fast startup and the Hibernate checkbox are unlocked with Change settings that are currently unavailable — every "off" gesture on your PC can be made to do exactly what you expect.
