Keep Windows awake without changing everything

Screen off, sleep and lock are different things

• Screen off: the display goes dark but programs keep running. Downloads continue.
• Sleep: the computer pauses almost everything to save power. Downloads and renders stop.
• Screen saver and lock: a screen saver starts after a wait time and can require sign-in when you return. Companies often enforce this with a policy.

If your problem is a dark screen while you read, a temporary display method such as the browser keep-awake tool is enough. If a long task stops overnight, you need to prevent sleep.

Windows 11: change the screen and sleep timeouts

1. Open Start > Settings > System > Power & battery.
2. Expand Screen, sleep, & hibernate timeouts.
3. Set Turn my screen off after and Make my device sleep after, separately for plugged in and on battery^[1].

Recent Windows 11 updates shortened some defaults on new installations, for example the screen-off time on modern-standby devices^[2]. If your screen started turning off sooner than before, check these values first.

Prefer changing the plugged in values and leaving battery values short. That keeps the laptop from draining in a bag.

Windows 10

Windows 10 has the same two timers under Settings > System > Power & sleep. Microsoft's current power article covers Windows 11 only, and Windows 10 support ended in October 2025, so menu names on your PC may differ slightly. PowerToys Awake and the browser tool work in the same way on both versions.

Stop the screen saver from starting

Go to Settings > Personalization > Lock screen and open Screen saver under Related settings. There you can change Wait or untick On resume, display logon screen^[3]. On a managed PC these options may be greyed out because a policy sets them.

PowerToys Awake: temporary keep-awake without changing your power plan

PowerToys is a free Microsoft utility collection. Its Awake module keeps the PC awake without modifying your Windows power plan settings: it asks Windows for a power state instead^[4]. Modes:

• Keep using the selected power plan: Awake is inactive.
• Keep awake indefinitely: until you change the mode or close PowerToys.
• Keep awake for a time interval: for example two hours.
• Keep awake until expiration: until a date and time.

By default the displays can still turn off while the computer stays awake. Turn on Keep screen on if you also need the display. Awake does not keep the display on at the lock screen^[4].

PowerToys Awake not working? Check that the mode is not “Keep using the selected power plan”, that Keep screen on is enabled if the problem is the display, and that a company policy is not locking the PC. Installing PowerToys may need permissions you do not have on a work computer; in that case see keeping a computer awake without software.

See what is keeping Windows awake (or not)

In a Command Prompt, powercfg /requests lists the power requests from apps and drivers that currently prevent the display from turning off or the system from sleeping^[5]. It is useful to confirm that a presentation app, a video or PowerToys is really holding a request. Depending on your setup, you may need an administrator prompt.

powercfg /requests

Presentations, downloads and chat status

For presentations and long downloads, follow the checklist in preventing sleep during long tasks. Keep in mind that none of the methods above creates keyboard or mouse input: a power request keeps the display on but does not stop chat apps from showing you as away. That difference is explained in the comparison of alternatives.
