ELECTRONIC SYSTEM, TERMINAL DEVICE, AND FUNCTION EXPANSION DEVICE
First Claim
1. An electronic system comprising:
- a first electronic device; and
a second electronic device that is connected to the first electronic device and that receives an electric power supply from the same power supply as that of the first electronic device, whereinthe first electronic device includesa load that consumes electric power,a state notification unit that notifies, when an amount of electric power consumption of the first electronic device is small, the second electronic device of a small electric power consumption state, anda power-on management unit that notifies, in response to an instruction to turn on a power supply, the second electronic device that the power supply is turned on and that starts the electric power supply to the load, andthe second electronic device includesan electric power control unit that decreases, when a notification of the small electric power consumption state is received from the state notification unit, electric power consumption of the second electronic device when a notification that the power supply is turned on is received from the power-on management unit and that increases, when a notification of the small electric power consumption state is received from the state notification unit, the electric power consumption of the second electronic device when the notification that the power supply is turned on is not received from the power-on management unit.

Abstract
A terminal device includes a state acquisition unit that notifies, when an amount of electric power consumption of the terminal device is small, a docking station of a small electric power consumption state and a power-on management unit that notifies, in response to an instruction to turn on a power supply, the docking station that the power supply is turned on and that starts an electric power supply to a CPU. The docking station includes a charge setting unit that decreases, when a notification of the small electric power consumption state is received from the state acquisition unit, electric power consumption of the docking station when a notification that the power supply is turned on is received from the power-on management unit and increases the electric power consumption of the docking station when the notification that the power supply is turned on is not received from the power-on management unit.
