If OBS stops sending your YouTube live stream when your computer sleeps, keep the computer awake for the broadcast by changing its sleep timeout. You can usually let the display turn off separately; screen-off and computer sleep are different power settings.
On Windows 11, the timeout is under Settings > System > Power & battery > Screen, sleep, & hibernate timeouts. Set the sleep timeout for the power condition you will use, especially if the computer will be plugged in. This is a system-state explanation applied to OBS and YouTube, not a tested diagnosis for every setup.
Why sleep interrupts an OBS stream
OBS is an application running on your computer. While the computer is awake, it can process the scene, encode the video and send the stream over your network. When the computer enters sleep, it is no longer in its normal working state. It is therefore reasonable to infer that OBS cannot continue its ordinary work of sending the broadcast during that time.
Microsoft describes system power states in its Windows documentation. That documentation explains the operating-system states; it is not an OBS or YouTube test, and it does not establish exactly what every device, driver or stream will do on entering and leaving sleep. The practical first check is still straightforward: did the computer itself sleep when the broadcast stopped?
This distinction matters because the symptoms can look similar. If the screen goes black, you may assume the whole machine has slept, even when it is still running OBS. Conversely, a computer can be set to sleep after a period of inactivity even if you expected a live application to keep it awake. Do not use the monitor going dark as proof that the computer remained active.
The setting to examine is the computer’s sleep timeout, not simply the display timeout. A longer sleep timeout or no automatic sleep during the session lets you decide when the computer can rest. The trade-off is power use: a computer kept awake consumes power, and a laptop left on battery may run down sooner than expected. Choose a setting that fits the duration and power source of your broadcast.
A similar interruption can affect other continuous playback setups. If you are deciding whether a locally run playlist is appropriate for an always-on channel, this guide to running a YouTube station around the clock gives useful context about the demands of continuous operation.
Check whether the computer or only the display sleeps
First establish what actually happened at the time of the drop. If the display went dark but the computer’s fans, keyboard lights, audio or other activity continued, the display may simply have switched off. Those clues are not conclusive on every machine, so check the configured timeouts and, where possible, the system’s wake or power history as well.
A display timeout controls when the screen turns off after inactivity. A sleep timeout controls when the computer enters a lower-power state. Windows provides separate controls for these behaviours. That separation is useful for a stream: you can allow the monitor to turn off while preventing the computer from sleeping. The screen does not need to remain lit merely because OBS needs the computer to remain awake.
The simplest test is to note the clock time, leave OBS running, and observe whether the computer becomes inactive at the configured sleep timeout. If the stream stops at that point, adjust the computer sleep setting and test again. If the display turns off but the stream continues, that is evidence that screen-off alone did not interrupt this test; it does not guarantee identical behaviour on every future run.
If the machine is managed by an employer, school or other administrator, its power settings may be restricted. A laptop maker may also provide additional power controls. If the Windows setting is missing, greyed out or changes back, check with the administrator or the manufacturer’s documentation rather than assuming OBS is responsible.
Change the Windows 11 sleep timeout
On a typical Windows 11 installation, open Settings > System > Power & battery > Screen, sleep, & hibernate timeouts. Microsoft documents the power and battery controls on its Windows 11 power settings page. The labels or available choices can vary with the device, Windows version and management policy.
Find the sleep controls, rather than changing only the screen timeout. Windows may show separate sleep choices for when the device is plugged in and when it is on battery. Choose a longer period or a setting that prevents automatic sleep for the power condition you will actually use during the broadcast. Do not assume a plugged-in selection applies when the laptop later runs on battery.
You can leave the display timeout shorter if you want the monitor to go dark during a long broadcast. For example, a laptop could be set to turn off its display after a period of inactivity while remaining awake on its power adapter for the stream. This reduces the time the screen stays illuminated without deliberately putting the computer itself to sleep.
Check the setting again after changing it. If you are using a manufacturer power utility, a dock or a managed device, another control may affect the behaviour. Windows versions and customised settings can differ; if the documented path does not match your computer, search the Settings app for “sleep” or consult the device maker’s support information. Avoid making broad changes to unrelated power or security settings just to keep OBS running.
Set the timeout for the power condition in use
The right timeout depends on how the computer will be powered during the stream. A desktop will generally be operating on mains power; a laptop may switch between its adapter and battery if a plug is disturbed or the broadcast moves location. Windows’ separate controls mean the timeout selected for one condition might not be the one currently in effect.
| Broadcast situation | Setting to check | Practical choice |
|---|---|---|
| Desktop or laptop staying plugged in | Sleep timeout while plugged in | Extend it beyond the planned session or prevent automatic sleep for that session |
| Laptop broadcasting on battery | Sleep timeout while on battery | Choose a period that covers the session, while accounting for battery use |
| Screen may go dark | Display timeout | Set independently; the display can turn off while the computer remains awake |
| Managed or customised computer | Available sleep controls | Confirm with the administrator or manufacturer if the control is unavailable or overridden |
This is a decision guide, not a promise that every device exposes the same options. Some systems apply additional rules for battery health, thermal behaviour, lid closure or organisational policy. In particular, closing a laptop lid can trigger a separate action from the ordinary inactivity timeout. Check the lid behaviour before relying on a closed laptop for a live session.
For a broadcast that matters, set the timeout before going live and keep the intended power connection in place. A long timeout is not the same as a guarantee against power loss, a crash or a network interruption. It addresses one avoidable risk: the computer entering sleep because it was idle.
Keep the computer awake during the session
For a planned live session, decide how long the computer needs to remain awake and select a sleep timeout accordingly. If you disable automatic sleep temporarily, make a note to restore your normal setting afterwards. Leaving a machine awake indefinitely can use more electricity and is not always appropriate, particularly on a laptop running on battery.
Keep ventilation clear and place the device somewhere stable. A power connector that is easy to knock loose can turn a planned plugged-in session into a battery session, which may use a different timeout. If the laptop is closed, verify the lid action; do not infer that the display-off setting covers lid closure.
On a Mac laptop, Apple documents a power-adapter setting called Prevent automatic sleeping on power adapter when the display is off. It is relevant when the Mac is plugged in and you want it to keep working after the display turns off. Apple also notes that preventing sleep can increase power consumption. Check the current Apple Battery settings guidance and its sleep and wake guidance for the version of macOS you use; settings and names can change.
If the repeated task of leaving a computer awake and checking it overnight is the part that is difficult to sustain, StreamNeo can remove that particular computer-at-home dependency: you upload a video, provide your YouTube stream key and the broadcast runs while your own computer is switched off. It is YouTube-only, so it does not replace an OBS setup that needs live scene changes, capture sources or other computer-controlled interactions.
Verify the stream remains connected
After changing the power setting, run a test that resembles the real broadcast. Keep the computer on the power source you plan to use, start OBS and check that the stream is live in YouTube. Let the screen turn off if that is how you intend to operate, then confirm that the computer remains awake and the broadcast is still progressing. A brief test cannot establish that a long session will never fail, but it can catch a timeout mismatch before an overnight run.
Check OBS and YouTube separately. A preview that continues to move in OBS does not by itself confirm that YouTube is receiving the stream. Conversely, a temporary delay in the YouTube viewing page is not proof that OBS has stopped transmitting. Look for the status indicators in both applications and check whether the live page continues to update.
OBS has an automatic reconnect control under its Advanced settings. Its connection troubleshooting documentation describes reconnect behaviour and network troubleshooting. Reconnect is a recovery aid for a transient connection loss; it should not be treated as a way to keep OBS transmitting while the computer is asleep. Configure it if useful, then test what happens after a brief ordinary network interruption, not by relying on sleep as a recovery test.
If the computer stayed awake when the stream dropped, investigate the connection rather than repeatedly changing sleep settings. OBS identifies unstable Wi-Fi, network software, drivers and hardware among possible causes. As a diagnostic, compare Wi-Fi with a wired Ethernet connection if one is available. A wired test can help isolate Wi-Fi instability; Ethernet is not a fix for a computer that is sleeping.
Also check whether a VPN, firewall, antivirus product or network-prioritisation utility is interfering. Change one factor at a time and follow the relevant vendor’s guidance rather than disabling security protections broadly. If the fault remains, OBS recommends working through its connection guidance and considering the network path, including the router, network adapter or ISP. This is separate troubleshooting from the Windows sleep-timeout fix.
For connection-specific background, the guide to a YouTube stream that keeps disconnecting on JioFiber discusses a different network context. The useful distinction is whether the computer slept at the moment of failure or remained awake with a genuine network drop. If your concern is instead a scene or playlist behaving unexpectedly, the OBS source visibility checklist covers another class of OBS problem.

FAQ
Does the monitor have to stay on while OBS streams?
No. The display can often turn off while the computer remains awake, because display timeout and computer sleep are separate controls. Verify the behaviour on your own system rather than assuming the screen going dark means the stream stopped or continued.
What should I change in Windows 11?
Open Settings > System > Power & battery > Screen, sleep, & hibernate timeouts and adjust the sleep timeout for the power condition in use. You can set the display timeout separately if you want the monitor to turn off during the stream.
Is sleep definitely the cause of every OBS disconnection?
No. The explanation that OBS cannot continue its ordinary work while the computer is asleep is an inference from operating-system power-state documentation, not a tested diagnosis for every OBS and YouTube combination. If the computer stayed awake, investigate network stability and OBS connection settings instead.
Will OBS automatic reconnect solve sleep interruptions?
It can help OBS recover from some transient connection losses, but it is recovery behaviour, not a way to transmit while the computer sleeps. Keep the computer awake for the session and test reconnect behaviour separately.
