Chromebook Freezing or Slow



Issue in Zoom or Meet

Teleconferencing systems were never meant for the load schools and remote-workers are putting them through. School Chromebooks are light-weight personal computing devices and they weren't optimized for using these services all day, every day. We've collected a series of tips and workarounds to help improve your experience. Please be aware, these won't make the issues go away completely until the service providers enhance their systems and optimize for delivery to Chromebooks.

  1.       Switch to Speaker View (Zoom) - or Change your Layout (Meet); here are the layout options in Meet:
    •     Auto—Allows Meet to choose the layout for you.
    •     Tiled—Shows up to 16 people when there is no presentation.
      •     Move your mouse to see participant names. 
      •     If someone joins after the meeting starts, their image is at the bottom of the screen. 
      •     Presentations appear in a large tile, with the most active participants to the side.
    •     Spotlight— The presentation, active speaker, or pinned feed fills the window. 
    •     Sidebar— You see the active speaker or presentation with additional participants on the side.
    •     Tip: —  When you choose a new layout, your preference is automatically saved. 
  2.       Request smaller groups with your Teacher. Large groups (10+) can cause lag and delay on Chromebooks
  3.       Limit multi-tasking, or doing a lot of other things in other tabs. Every tab opened takes away resources from your Zoom/Meet. Don't stream video or music or have a bunch of tabs open while on your video call.
  4.       Limit unnecessary household internet usage (like streaming TV/Netflix, Music, etc). Our homes are filled with Internet Of Things devices that eat up our limited wireless bandwidth. Use only what you need, when you need.

  Reboot your Chromebook and Remove your Profile

To reboot your Chromebook, Press and hold Refresh   + tap Power  , then release refresh.

Remove the student profile from the Chromebook. Your student's data should be safe in their Google Drive, but any pictures or videos stored locally might be lost.

  1.       Sign-in screen
  2.       Select the profile you want to remove
  3.       Next to the profile name, select the Down arrow.
  4.       Select Remove this user.
  5.       Confirm Remove this user.

Chromebook Sound Issues

If you are having problems with sound on your Chromebook, try the following suggestions:

Fix #1: Make sure the headphones are securely plugged in

Make sure you firmly insert and push the headphones in. Give it a good push until you hear a click.

Fix #2: Try a different set of headphones or earbuds

By connecting a different set you can determine if the problem lies with a pair of broken headphones rather than a problem with the Chromebook.

Fix #3: The “close lid” solution

  1.      Unplug the headphones.
  2.      Close the lid of the Chromebook and wait ten seconds.
  3.      Plug in the headphones.
  4.      Open the lid. The Chromebook will re-scan for audio devices and should find your headphones.  Or...
    1.      Turn off the Chromebook.
    2.      Plug in the headphones
    3.      Turn on the Chromebook. The Chromebook will re-scan for audio devices on startup and should find headphones.

Fix #4: Check sound settings

In the lower right corner of the screen are a series of icons. Find and Click on your account picture at the very right. A window will appear displaying information about the Chromebook.

  •     Make sure that the audio is at a high volume and not muted. 
  •     Make sure that the destination output is set to either headphones if you want to listen through headphones, or speakers if you want to listen through speakers.


Fix #5: Clear the cache

Clearing the cache on the Chromebook can resolve some audio issues. To clear the cache do this:

  1.       Click on the chrome setting button called the ellipsis in the browser in the top right corner (it looks like three horizontal lines or 3 vertical dots.)
  2.       Click on Tools or More Tools and then Clear browsing Data, 
  3.       Select Advanced
  4.       Specify to clear information 'From the beginning of time'.
  5.       The option 'Empty the Cache' is related to sound troubleshooting.
  6.       Click 'Clear Browsing Data'
  7.       Turn the chrome book off and then on again and try the sound.


If you require additional support and the provided troubleshooting does not resolve your issues, please contact your school for a replacement device.
