A managed Chromebook is set up and maintained by a school or company. If you believe you've received a managed device in error and you are the owner, try one of these options.
Option 1: Contact the device manager
First, find the name of the school or company that manages your Chromebook. You'll see this name on the "Enterprise enrollment" window that shows when you first set up your Chromebook.
Then contact the organization and ask the administrator to deprovision your Chromebook.
Note: If you don't see the "Enterprise enrollment" window, and don't see a name of a school or company, your device is not managed. Try turning your device off, then on again. If your issue isn't fixed, try wiping your device.
Option 2: Return your Chromebook
Try returning your Chromebook to the place you purchased it, then exchange it for a different Chromebook that's not managed by a school or company.
More information about enrollment
Some schools and companies use forced re-enrollment, which keeps their Chromebooks under the administrator's control if the devices are reset. This means the devices can be easily reset and shared between students or employees.
