Symptom
Your laptop becomes slow while Companion runs. Apps take longer to open. The screen becomes sluggish. A fan gets loud.Why this happens
Companion shares resources in your laptop with every other open app. A slowdown starts when the laptop runs out of resources.Fix
1
Close the apps and tabs you are not using
Do this before you click Start session.
- Close every app you are not using.
- Close every browser tab you are not using.
- Close extra browser windows.
- Close large files, such as a big spreadsheet or a slide deck.
- Keep open only the apps that your work needs.
This is about the apps you have open in your laptop. It is not about disk space or about files on your computer.

Use Microsoft Teams in a web browser
If your company uses Microsoft Teams: the desktop app sometimes interferes with Companion. It also uses more resources than Teams in a web browser.You have two options:
- Best option: use Teams in a web browser at teams.microsoft.com. Close the Teams desktop app.
- Second option: click Pause in Companion before you open the Teams desktop app. Click Resume when you finish the call.
If that did not help, find the app that slows your computer
Some apps use more resources than others. This slows your computer down. Find that app. Close it if you can.Talk to your IT team first.Ask your IT team which apps may slow down your computer. They can help you with the diagnosis. They also know which apps your company needs you to keep open.

- Close the apps and tabs you are not using first. Then start Companion.
- Share one screen, not two. Two screens use more resources.
- Run Companion in its own browser window.
When to contact support
Contact your own IT team first. They can tell you which apps slow down your computer. They can also close or remove an app that your company does not need. Contact Within support after that, when both of these are true:- Your laptop is still slow after you close the apps you are not using.
- Your IT team says that Companion or Chrome is the cause.
