FAQ: Warranty Registration
Warranty Registration client captures first boot time. This information is shared with Warranty Server. First boot time is typically used when the device is not registered.
The best way to stop the reminder notifications is to register the device warranty. If that is not possible or you don’t wish to register the warranty, select the notification and there will be an option to “NEVER” receive the reminder notifications again. This “NEVER” setting will NOT survive a factory reset, so on device reset, you will have to open the notification and select NEVER again.
While it is not mandatory to register for warranty, it does save time in the event a device service request is required.
