What do I do if my cursor disappears or my touchpad stops working on my Chromebook? 

1. If your cursor disappears or freezes on your screen, the best solution is to reboot your Chromebook.
2. You can use the touchscreen or you can press SHIFT +CTRL +q +q again to sign out of your account.
3. Once signed out of your account, go to the bottom left corner of the Chromebook and select SHUT DOWN. 
4. Restart your device and see if it is working.
5. Other items to check are extensions that are loaded (try disabling one at a time to troubleshoot) and the amount of space available on the Chromebook.  
6. If the problem continues, please contact mbssupport@mtnbrook.k12.al.us
