You can enable or disable Microsoft Edge’s “Automatically put tabs to sleep” feature to optimize your PC’s performance and reduce resource usage.
This setting automatically frees up system resources like RAM and CPU power from inactive browser tabs after a set period, with the default being 30 minutes.
When you turn this feature on, Edge efficiently manages background tabs, preventing them from slowing down your computer, especially when you’re juggling multiple open windows.
You can easily control this setting within Edge’s browser configuration menus.
Turn on “Automatically put tabs to sleep” in Edge by going to Settings, then System and performance. Ensure the toggle for “Automatically put tabs to sleep” is switched to the On position. You can also adjust the inactivity time before tabs go to sleep in this section.
Why Doesn’t a Tab Go to Sleep?
Microsoft Edge is smart about which tabs it puts to sleep. It won’t put a tab to sleep if it thinks you might still need it. Here are some common reasons why a tab might stay awake:
- The tab is the one you are currently looking at (the active tab).
- The tab is playing sound.
- The tab is actively recording your screen or webcam.
- You are using developer tools on that page (like checking code).
- You’re using another tab in the same tab group.
- It’s a website from your company that you are browsing.
- The tab is using special web features like WebUSB.

Summary
Sleeping Tabs in Microsoft Edge help your computer run faster. When tabs are not used for a set amount of time, Edge puts them to sleep. This saves computer memory and power. The tabs don’t close; they just pause. To wake a tab back up, just click on it. This feature is usually on by default, but you can check and adjust it in the Edge settings under “System and performance.”
