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 won’t put a tab to sleep if it’s actively playing sound, recording your screen, or if it’s the tab you’re currently using.
- 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.
