Computing device, computing device system and power control method
First Claim
1. A computing device comprising:
- a coupler configured to couple to a display device having a chargeable first battery and be able to be separated from the display device, wherein charging to the first battery and wired communication with the display device can be performed via the coupler at a time of being coupled to the display device;
a coupling detector configured to detect whether the coupler is coupled to the display device;
a wireless communicator configured to communicate wirelessly with the display device when the coupler is being separated from the display device;
an external power supply connector configured to be supplied with power from an external power supply;
a chargeable second battery;
a connection detector configured to detect whether power is supplied to the external power supply connector; and
a controller configured to control charging and discharging of the first battery and the second battery on the basis of whether the power is supplied to the external power supply connector when the coupler is being coupled to the display device.

12. A power control method comprising:
-
detecting whether a computing device having a chargeable first battery and a display device having a chargeable second battery is separated or coupled each other, wherein the display device and the computing device communicate wirelessly each other when being separated and perform wired communicate each other when being coupled, and charging to the first battery from the computing device and charging to the second battery from the display device can be performed when being coupled;
detecting whether power from an external power supply is supplied to the computing device; and
controlling charging and discharging of the first battery and the second battery on the basis of whether the power is supplied from the external power supply when the display device and the computing device are being coupled each other. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
