Change Screen and Sleep Timeouts in Windows 11

Your screen turns off, or the laptop drops to sleep, much sooner than you want — or you simply want to choose your own timeouts.

Why: Windows 11 has separate screen-off and sleep timers for battery and plugged-in, and an aggressive default (or Energy saver) can make them very short. You can set each one yourself.

Fix 1: Set the timeouts in Settings

1. Open Settings > System > Power & battery > Screen, sleep, & hibernate timeouts.
2. Under Turn my screen off after, pick how long Windows waits before the display turns off — set this separately for On battery power and When plugged in.
3. Under Make my device sleep after, pick how long before the device sleeps — again for battery and plugged in.

Choose Never for either if you don’t want that action while plugged in. (Power-efficient settings here help battery life by powering down when you’re away, so very long timeouts on battery will use more charge.)

Fix 2: If your timers keep resetting to a few minutes — turn off Energy saver

A common cause of “it sleeps after only a few minutes no matter what I set” is Energy saver overriding your timers:

1. Open Settings > System > Power & battery.
2. In the Energy saver section, switch it Off.
3. Open the Energy saver settings link and set Turn on energy saver automatically to Never (or only at a low battery percentage).

With Energy saver no longer forcing things, the timeouts from Fix 1 take effect.

Fix 3: Set the timeouts instantly from the command line

To set them without clicking, use powercfg /change (values are in minutes; 0 means never). In Command Prompt or PowerShell:

powercfg /change monitor-timeout-ac 15
powercfg /change monitor-timeout-dc 5
powercfg /change standby-timeout-ac 30
powercfg /change standby-timeout-dc 10

Here -ac is plugged in and -dc is on battery; monitor-timeout is the screen and standby-timeout is sleep. The example sets screen-off to 15/5 minutes and sleep to 30/10 minutes.

FAQ

What’s the difference between screen-off and sleep? Screen-off just turns the display dark — the PC keeps running. Sleep puts the whole PC into a low-power state. You can set them to different times.

My sleep option is missing or greyed out. This often means Energy saver or a group policy is controlling it — try Fix 2, or use the command line in Fix 3 which sets the values directly.
