If your YouTube radio livestream is encoded on your computer, the computer needs to stay awake to process and send it. System sleep can pause that work and interrupt the stream; the display switching off is a separate setting and does not, by itself, stop the computer running.
For an overnight broadcast, first find out where the encoder is running, then set the computer to remain awake for the planned session while allowing the screen to turn off. If the stream must continue after that computer sleeps or shuts down, encoding needs to run somewhere else.
Why sleep can stop the livestream
A computer-based stream is not simply a video file being handed to YouTube once. An encoder such as OBS reads the media or other sources, prepares the audio and video, and sends a continuing stream of data over the network. The computer doing that work must be operating normally while the broadcast is in progress.
System sleep is a low-power state in which ordinary applications do not keep working as they do when the computer is awake. If the encoder pauses or loses its ability to send data, YouTube may stop receiving the broadcast. The exact result can depend on the computer, its power state and the streaming software, so treat sleep as a likely cause to investigate rather than a diagnosis of every interruption.
This distinction matters if you start a devotional playlist or radio loop in the evening and find it offline in the morning. A dark screen is not proof the computer slept. Windows describes the system as fully running whether its screen is on or off; the display and system power state are separate. See Microsoft's explanation of Windows system power states.
Other issues can interrupt a stream too. A network drop, an encoder error, a YouTube-side playback problem or a source that has stopped may look similar from a viewer's perspective. Check the encoder's connection status and YouTube's live dashboard before changing several settings at once. If the dashboard shows a stream that is receiving data but viewers report playback trouble, monitoring a 24/7 podcast stream for playback errors offers a related way to think about what you can verify.
Check whether the encoder runs on this computer
Start with the device that is actually sending the broadcast, not necessarily the computer beside you. Open the streaming programme or service you used to begin the stream. If OBS, another encoder or a browser-based broadcasting tool is open on the computer, and that tool shows a live connection, this computer is doing the encoding. Its awake state matters.
A YouTube stream can also be sent from a different computer or a hosted arrangement. In that case, your personal laptop's screen and sleep settings may have no effect on the active broadcast. Check which device or service you started, and where its video source and stream key are being used. Do not assume that a video uploaded to a platform continues broadcasting by itself; uploading a file and encoding a live stream are different tasks.
A useful check is to look at the encoder while the stream is running, then check again after the screen goes dark. If the connection remains active and the stream is still visible, the screen-off event has not stopped it. If the computer has entered sleep, check whether the encoder paused, disconnected or needs to reconnect after wake. The OBS forum has a community answer saying a PC must be fully on to stream, but that is community guidance rather than a formal OBS specification; the underlying point is that an encoder running locally needs its computer operating.
If you use OBS to loop recorded material, distinguish power trouble from source setup trouble. A playlist can have its own behaviour when one item ends, regardless of sleep. The guide to setting up an OBS VLC video source for a YouTube Live playlist is relevant when the encoder is awake but the intended media sequence is not continuing.
Separate display timeout from system sleep
Most computers offer separate controls for when the display goes dark and when the whole device sleeps. Turning off the display can reduce light and screen activity while leaving the computer awake. Putting the computer to sleep is different: the normal processing that a local encoder depends on may no longer continue.
This is the distinction to test, not an assumption that the display must remain lit. Set a short or otherwise convenient display timeout if you want a dark room, and set the sleep timeout so the computer stays awake for the broadcast. The appropriate values depend on how long your stream should run and whether the computer is plugged in. The goal is not to keep every screen on; it is to prevent system sleep during the period the local encoder must work.
A laptop can have different timeout choices on battery and on power. Check the condition that applies to the planned broadcast. A setting for “when plugged in” will not necessarily govern a session running on battery. If you change only the display setting, you may not have changed the sleep behaviour at all. Conversely, a computer can remain awake with its display dark, which is the useful arrangement for many overnight streams.
Do not use the screen as your only indicator of system state. When the display is dark, move the mouse or press a key and observe whether the computer wakes immediately or appears to resume from sleep. Look at the encoder and operating system power settings as well. This simple check helps separate an ordinary display timeout from a sleep transition that could explain an interruption.
Keep the computer awake during the broadcast
For a local encoder, set the system sleep period to cover the full planned broadcast, then test it under the same conditions you expect to use overnight. If the computer is a laptop, use a suitable power source where practical. A long stream can consume battery, and the available runtime varies with the device, workload and battery condition; there is no dependable runtime estimate to apply to every laptop.
It is usually better to use the operating system's built-in power controls than to install a separate “keep awake” utility or rely on a persistent command-line request. Windows supports application requests that can keep a system awake, but Microsoft's guidance warns against holding a continuous sleep-prevention request indefinitely, particularly because it can drain battery on Modern Standby devices. See Microsoft's documentation on system sleep criteria. For a planned broadcast, choose a clear power setting and restore a shorter sleep period when you no longer need the computer awake.
There is a trade-off. Keeping a computer awake uses more power than allowing it to sleep, even with its display off. If you are using the same machine for other work, a long sleep timeout may also leave it active when you have finished streaming. Make the broadcast schedule part of your routine: confirm the stream, leave the computer in the intended power state, and return the timeout to your usual setting afterwards if appropriate.
If your stream uses a media file, confirm it is genuinely looping and not relying on you to restart it. Sleep settings solve a power-state problem, not a playlist problem. For a recorded-video workflow, streaming recorded videos on YouTube around the clock with a Raspberry Pi describes a different always-on computer arrangement; it does not remove the need to configure and test the device doing the encoding.
Adjust Windows 11 screen and sleep settings
In Windows 11, open Start > Settings > System > Power & battery > Screen, sleep, & hibernate timeouts. Microsoft's Windows 11 power settings guide documents this path and the separate choices for turning the screen off and putting the device to sleep. Labels can change with Windows updates or device configuration, so use the current settings shown on your computer if the wording differs.
Find the controls labelled Turn my screen off after and Make my device sleep after. Set the screen timeout to suit the room and your preference. Set the sleep timeout long enough that the device will remain awake through the broadcast. Where Windows offers separate choices for plugged-in and battery use, change the one that matches the session. If the broadcast is meant to run overnight, a timeout that expires before morning will not meet that requirement.
You do not need to set the display timeout and sleep timeout to the same period. For example, the display can turn off while the device remains awake until the stream is scheduled to finish. That is the practical way to avoid a lit screen without asking the encoder to work through system sleep. Review the actual selection after changing it rather than relying on memory or on a power profile you used previously.
For a Mac, the controls are different. Apple documents display timing under System Settings > Lock Screen, and a Battery option called Prevent automatic sleeping on power adapter when the display is off for use on a power adapter. Apple's instructions are at If your Mac sleeps or wakes unexpectedly. That option is specifically about power-adapter use; do not assume the same behaviour on battery. Available controls can vary by macOS version and Mac model.
Test the encoder and stream after changes
Do not wait for a full overnight failure to learn whether the new setting works. Run a controlled test while you can check the computer and the YouTube live dashboard. Start the encoder, confirm it is sending, let the display turn off if that is the intended arrangement, then check that the encoder remains connected and the stream is still receiving data. A test should imitate the power condition and timeout settings you plan to use.
After the display has been off for a while, wake it and inspect the encoder's status or logs. Note whether the connection continued, whether the programme reported a reconnect, and whether YouTube recorded an interruption. If the stream stopped, change one relevant factor at a time: verify the system did not sleep, then check the network and encoder. This makes it easier to tell whether the sleep setting was the cause or only coincided with another fault.
Also test after a restart or after changing power profiles if you expect those events to occur. A setting that works while plugged in may not apply on battery, and a different Windows power mode may expose different options. Keep a short record of the setting and result, particularly if another person helps operate the channel. This is more useful than assuming a successful start means the setup will run all night.
If the computer stayed awake and the encoder stayed connected but viewers still could not watch, investigate the stream itself rather than repeatedly changing sleep settings. Check the live dashboard, encoder status and available logs. A stream can fail for reasons unrelated to sleep, and no single display or power setting can rule those out.
Consider power or network loss
Keeping the computer awake addresses one specific failure mode: the local encoder being paused by system sleep. It does not guarantee that a broadcast survives a power cut, a router restart, an internet outage or an encoder crash. If the power supply goes away, a computer without backup power may stop; if the network is down, the encoder cannot send data by that connection.
Think through the weak points in the actual route: the computer, its power source, the router and the internet connection. A laptop battery may provide some time away from mains power, but its duration depends on the machine and workload. A desktop generally depends on its power supply. Do not treat a backup device or a different connection as a guarantee; test any contingency you intend to rely on, and check what happens when connectivity returns.
There are two broad operating arrangements. You can keep the current computer awake with the display off, or run the encoder on a different computer or hosted service. The first preserves a familiar setup but requires local power, network access and an awake device. The second means the stream is not dependent on this computer's sleep state, but requires a separate setup and ongoing service arrangements. Neither removes the need to check the live stream and understand what happens on interruption.
| Arrangement | What it changes | What to consider |
|---|---|---|
| Current computer awake, display off | Keeps the local encoder operating while the screen can go dark | Local power use, network stability and the sleep settings for the applicable power condition |
| Another computer runs the encoder | Moves the encoding work to a different active device | Setup, media availability, power and network at that device |
| Hosted encoding arrangement | Places the active encoding outside the computer you normally use | Service requirements, setup, ongoing terms and how interruptions are reported |
If you want to keep a local OBS workflow but move the workload to another machine, a comparison of Azure VM and VPS options for 24/7 YouTube streaming in India may help frame the questions. That is a separate hosting decision, not a necessary fix when your only problem is an incorrectly short sleep timeout. Consider local power and broadband conditions as well as the hosting arrangement, and verify the current details before choosing.
For a channel that needs the broadcast to continue after your own computer is shut down, StreamNeo can remove the need to leave that local computer running: you upload a video and provide the YouTube stream key, then the broadcast runs without that computer. It is YouTube-only and is a separate hosted arrangement, not a setting that makes a sleeping local encoder continue working. Decide first whether changing the sleep timeout is enough for your needs.

FAQ
Does turning off my screen stop a YouTube livestream?
No. A screen turning off is different from system sleep; the computer can remain fully running with its display dark. Confirm the separate sleep setting and check the encoder rather than using the dark screen as proof the computer stopped.
Can a local OBS stream continue while the computer is asleep?
If OBS is the encoder running on that computer, it needs the computer awake to keep processing and sending the stream. Sleep suspends normal application operation, so the stream may stop. The OBS forum answer on this subject is community guidance, not a formal OBS specification.
What should I change in Windows 11?
Open Settings > System > Power & battery > Screen, sleep, & hibernate timeouts. Choose the screen-off timing you want and a sleep timeout that covers the broadcast, checking the plugged-in or battery setting that applies. Test the result before relying on it overnight.
What if the stream still stops after I change sleep settings?
Check whether the computer actually slept, whether the encoder remained connected, and whether YouTube's live dashboard shows incoming data. If the device stayed awake, investigate network and encoder status rather than assuming the display setting caused the interruption.
