Abstract: A system for detecting proper positioning of an accessory, including an electronic device and an to be attached accessory. The electronic device includes a first attachment component, a magnetometer, and a processor. The to be attached accessory includes a second attachment component. The second attachment component is configured to be attached to the first attachment component, so that the to be attached accessory is fixed through attachment to the electronic device in a first orientation or a second orientation. The magnetometer is further configured to be triggered by a combined magnetic field of the first attachment component and the second attachment component to output the magnetic field intensity information when the accessory is fixed through attachment to the electronic device in the first orientation or the second orientation. The processor indicates whether the accessory is fixed in position based on the magnetic field intensity information.

Abstract: This application provides an electronic device and a stylus in-position determining method. The electronic device includes: an inverter circuit. When a Q value of the transmit coil is detected, the controller controls the resonant capacitor adjustment circuit to operate; the Q value detection circuit is configured to obtain a voltage signal representing a Q value; and the controller obtains the Q value based on the voltage signal, and when the Q value is greater than a preset threshold, determines that a stylus is attached to the electronic device. The resonant capacitor adjustment circuit participates in operation during Q value detection.

Abstract: A terminal device includes: a tablet and a keyboard. The tablet includes: a first controller, a first charging port, and a battery. The keyboard includes: a second controller and a second charging port; and the keyboard includes no battery. The first controller communicates with the second controller through data lines in 3pin. When the first charging port is connected to a first external power supply, and the second charging port is connected to a second external power supply, when a charging power of the first charging port is greater than a charging power of the second charging port, the first charging port is selected to charge the tablet and power is supplied to the keyboard through a power line in the 3pin; otherwise, the second charging port is selected to supply power to the keyboard and the tablet is charged through a power line in the 3pin.
