Abstract: A device starting system and method. A display device and an accessory device are provided in the device starting system. When the display device is in a turn-off state and the accessory device is in a turn-on state, a user may perform an operation on the accessory device, and the accessory device collects to-be-verified fingerprint data in response to the operation of the user.
