If YouTube stops playing when your computer is idle, first work out whether you are watching a playlist in a browser or sending a live broadcast from an encoder on that computer. The first problem may be a computer sleep setting or YouTube’s player sleep timer; the second usually means the encoder computer has gone to sleep and stopped sending its feed.
Turning the display off is a separate action from putting the computer to sleep, but a dark screen alone does not prove that playback or broadcasting will continue. Change the setting that matches the interruption, then test it during a session rather than assuming the fix worked.
First identify what has stopped
“Stream” can mean two different things here. If you opened YouTube to watch a playlist or a live channel, your computer is receiving playback. If you started a broadcast in software such as OBS and sent it to YouTube, your computer is producing the broadcast. The settings to check overlap, but the symptoms and next steps do not.
For playback, note what happens when the interruption occurs. Does the video pause in the browser, does the whole computer become unresponsive until you wake it, or does only the display go black? If the computer wakes to a lock screen and the YouTube player is paused, system sleep is a likely part of the problem. If the computer is still responsive and YouTube has paused after a predictable interval, check the player’s own timer.
For broadcasting, look at the encoder on the computer that is sending the feed. If the encoder disconnects or stops when that computer sleeps, viewers may see the stream end or lose the live feed. YouTube’s documentation describes connecting an encoder to a live stream; keeping the host computer awake is a practical requirement for software running there to continue sending data. It is different from a viewer’s browser stopping playback.
If you are not sure which case applies, ask whether the channel owner started the broadcast on this computer or merely opened the channel to watch it. A viewer cannot fix a creator-side encoder interruption by changing their own sleep timer. Likewise, a creator troubleshooting an outgoing stream should not assume a viewer’s YouTube sleep timer explains the broadcast ending.
Check the computer’s sleep and power settings
When the entire computer sleeps, local browser activity and software running on it are suspended or disrupted. For a session that needs to continue, set the computer to stay awake for the relevant period. On a laptop, check the values for the power condition you will actually use: battery and plugged in can have different timeouts.
On Windows 11, open Settings > System > Power & battery > Screen, sleep, & hibernate timeouts. Find Make my device sleep after and set a longer interval or Never for the power condition used during the session. Microsoft’s Windows 11 power settings identify this screen as the place to adjust those controls. The menu and available choices can vary with the device and its management policies.
Set the screen timeout separately if you want the display to go dark while leaving the computer awake. For example, a laptop plugged in overnight might have a short screen timeout and no automatic sleep during the planned session. That arrangement saves the display from staying lit, but it is not a guarantee that a browser, YouTube player or encoder will behave correctly; verify the result in your own setup.
On macOS, inspect System Settings > Battery and the options for the current power state. Apple documents a setting called Prevent automatic sleeping on power adapter when the display is off on supported configurations. Desktop Mac sleep and wake controls are in Energy settings. Names and availability differ by Mac and macOS version, so use the closest current option shown on your device rather than looking for a checkbox every Mac must have.
Apple notes that preventing or delaying sleep can increase power use. For an overnight playback test or an extended broadcast, use mains power where practical, and restore your normal sleep behaviour when the session no longer needs the computer awake. On a battery-powered device, a long session with sleep disabled can leave you with a flat battery even if the stream itself is otherwise working.
Battery Saver or other power-saving modes can also affect activity while a laptop is on battery. Do not rely on a setting that allows or changes network behaviour during sleep to keep a sleeping computer streaming: the safer troubleshooting step is to prevent system sleep for the session. If this is a managed work or school computer and the option is unavailable, ask the administrator rather than trying to bypass a policy.
Screen off is not the same as computer asleep
A display timeout only turns off the screen. System sleep puts the computer into a lower-power state and can suspend the browser or encoder work that the session depends on. These are separate controls, which is why changing “turn off screen after” may not fix a computer that still goes to sleep.
To distinguish them, start playback or a test broadcast, let the display turn off, then check whether the computer remains active. A keyboard press or trackpad movement may wake the display without waking the computer from a deeper sleep state; the exact signs depend on the device. For a broadcast, check the encoder’s status and YouTube’s stream health from another device if possible, rather than judging only by the dark monitor.
Do not assume that switching off an external monitor, closing a laptop lid or locking the screen is equivalent to a display timeout. Lid-close behaviour may be configured to sleep the computer, and an external display can go dark while the host remains awake. Test the exact action you plan to use. A setup that works with the lid open and the display timeout enabled may not work when the lid is shut.
For a home devotional playlist, for example, you might want the laptop panel dark but the browser still playing through speakers. Configure display and sleep behaviour independently, then confirm sound continues after the panel goes dark. For a local news encoder, the relevant check is whether the outgoing stream remains healthy after the monitor switches off; an on-screen preview disappearing is not the same as the broadcast ending.
Check YouTube and browser timers
If the computer remains awake but browser playback pauses, check YouTube’s Sleep Timer. YouTube’s desktop sleep timer help explains how to open the video’s player settings, choose Sleep Timer, and set how long playback should run before it pauses. Adjust or disable it if it is enabled and you want the playlist to continue.
That timer belongs to YouTube playback. It is not the Windows or macOS sleep timeout and does not keep a computer awake. It also does not control an encoder’s outgoing live feed: a creator should investigate the encoder and host computer instead. This distinction matters when a viewer says, “Are you still watching?” or reports a pause after a while. Treat that wording as a clue to inspect the player, not proof that every YouTube playlist has the same automatic stopping behaviour.
If no player timer is enabled, check whether the browser itself is still running and whether the tab has been closed or reloaded. A browser or device may have its own power-management behaviour, but the official guidance cited here does not establish one universal browser cause for a playlist stopping. Test with the same browser, power state and playlist, and change one relevant setting at a time so you can identify which change matters.
A playlist owner who changes the sequence may also need to distinguish an order problem from a playback interruption. The guide to keeping a YouTube Live playlist in alphabetical order is relevant if videos play in an unexpected sequence, while this page is about the computer or player pausing altogether. For a class stream where the playlist itself is changed during a session, see whether you can change a playlist during a 24/7 YouTube class stream; an order or content change is not a substitute for checking sleep settings.
If you are encoding a live broadcast
If software on this computer is sending the broadcast, keep the computer awake throughout the session and maintain its network connection. YouTube’s encoder setup guidance explains how an encoder uses a stream URL and key to connect to a live stream. The encoder depends on the host computer continuing to run; if the host sleeps, the local work sending the feed can stop. This is a practical inference from the documented workflow, not a universal rule about every possible production arrangement.
Before changing settings, check the encoder’s own state. Is it still running? Does it show that it is streaming? Does YouTube Studio show an incoming signal and healthy stream? If the computer is awake but the encoder has stopped, investigate the encoder separately rather than repeatedly changing the operating-system timeout. A restart policy may be useful for a software crash, but it cannot make a sleeping computer keep producing a feed. The article on restarting OBS automatically after a crash covers a different failure mode.
Also distinguish a host sleep problem from a network interruption. YouTube advises creators to monitor stream health and to look at the encoder and outbound connection when viewers report a shared problem. If the computer stayed awake and the encoder still shows an issue, check the connection and YouTube’s current guidance before concluding sleep was responsible. Do not infer a cause just because an interruption happened overnight.
A standalone hardware encoder is a different production arrangement: the computer may not be the device producing the feed. That is only relevant if you already have such a setup or have a clear production reason to separate encoding from the computer. It is not a necessary purchase for ordinary browser playback, and it is not the first fix for a software encoder that stops because its host sleeps.
If keeping a computer awake is the ongoing operational burden, another way to handle a prerecorded channel is to use a workflow that does not depend on your personal computer remaining on for the broadcast. StreamNeo is relevant to that specific pain: you upload a video and provide your YouTube stream key, rather than leaving your own computer to run the continuing broadcast. It is YouTube-only, so it does not address every production setup or a viewer whose browser playback is pausing.
Test the change during a session
Make one change at a time. First, set the system sleep timeout for the power condition in use. If you want the display dark, set its timeout separately. Then run a test long enough to pass the point at which the interruption usually happened, observing the computer and the YouTube player or encoder. A short test that ends before the usual failure point cannot establish that the problem is resolved.
For browser playback, verify that the playlist advances, not just that one video continues. If the display turns off, confirm the computer remains awake and playback continues. If it pauses while the computer is awake, inspect the YouTube Sleep Timer and then investigate browser or network causes separately. Restore normal sleep settings after the test if you do not want the computer awake for longer than necessary.
For a creator broadcast, monitor both the local encoder and the stream status in YouTube Studio. The screen going black is not by itself evidence of a dropped broadcast, and a preview that looks frozen can be a different issue from the encoder losing its connection. If people watching from separate connections report the same interruption, compare their timing with encoder logs or status and follow YouTube’s current stream-health advice.
Keep a simple note of what you changed, the power state, whether the screen was off, and what stopped. This makes repeated overnight tests more useful than changing several power, browser and encoder settings at once. If the computer remained awake, the player timer was off and playback still paused, treat that as a separate browser, network or service issue; the sources above do not identify a single cause for every such case.
Choose the fix by the interruption
| What you observe | Setting or component to check | What it changes | Trade-off or limit |
|---|---|---|---|
| Computer enters sleep during browser playback | Windows or macOS sleep timeout for the active power state | Keeps the computer from sleeping for the selected session | More power use; battery and plugged-in behaviour can differ |
| Screen goes dark but computer remains awake | Display timeout, separately from sleep | Turns off the display without necessarily sleeping the computer | Does not guarantee a player or encoder will continue correctly |
| YouTube pauses after a timer while computer is awake | YouTube player Sleep Timer | Changes when that video pauses | Does not change system sleep or an outgoing encoder feed |
| Encoder stops when its host sleeps | Host computer sleep setting and encoder status | Keeps software on that computer able to send its feed | Does not explain a separate network or encoder failure |
| Computer and player remain active but playback still stops | Browser, network and service-specific troubleshooting | Investigates other possible causes | No single cause is established by the settings guidance here |
The practical order is to identify playback versus production, check whether the host slept, separate screen-off from sleep, and then inspect the player timer if you are watching. For an encoder, monitor the creator-side software and stream health. Avoid changing unrelated settings until you have evidence that the previous check did not address the interruption.
When your goal is an always-on prerecorded channel rather than simply watching YouTube, compare the computer-based and managed operating approaches on their actual constraints.

FAQ
Does turning off the screen keep YouTube playing?
Not necessarily. Screen-off and computer sleep are separate controls, and a display timeout does not guarantee that the player or encoder will continue. Test the precise screen, lid and power arrangement you plan to use.
Why does YouTube pause if my computer is still awake?
Check whether YouTube’s Sleep Timer is enabled in the player settings. If it is not, look at browser, network or other service-specific causes separately; system sleep is not the only possible reason for playback to stop.
Does the YouTube sleep timer stop a live broadcast I am sending?
The player timer is a playback control for the video you are watching, not the control for an encoder’s outgoing feed. If you are producing a broadcast, check the encoder, host computer and stream health instead.
Should I keep a laptop awake on battery overnight?
Only if you have accounted for the battery use and the session genuinely needs to continue. Plugging in for a long test is usually more practical, and you can restore your usual sleep settings afterwards.
