Abstract: A first electronic device has a first side provided with first and second contacts. The first contact is connected to a direct current power source and the second contact is grounded. A second electronic device has a decision circuit and a second side removably connected to the first side. The second side includes third and fourth contacts. When the first and second electronic devices are connected in a first configuration, the decision circuit outputs a first signal according to the first configuration, whereas when the electronic devices are connected in a second configuration opposite to the first configuration, the decision circuit outputs a second signal according to the second configuration.

Abstract: A power input circuit. A wireless power receiver receives power from a wireless power transmitter. A charging circuit is coupled to the battery. A first switch is controlled by a first control signal. A second switch is controlled by the first control signal. A third switch is coupled between the battery and the voltage input terminal and controlled by a second control signal. A fourth switch is coupled between the voltage input terminal and the charging circuit and controlled by a third control signal. A fifth switch is coupled between the wireless power receiver and the charging circuit and controlled by a fourth control signal. When the wireless power receiver receives power, the third switch and the fifth switch are closed to transmit the received power to the charging circuit for charging the battery, and the computer device is powered by the battery.
