Abstract
An electronic device includes a power supply and a power supply circuit. The power supply circuit is configured to alternately switch a state of the electronic device between a first state to supply power to another device and a second state to receive power from said another device, and stop a switching operation of the state of the electronic device when the electronic device is off, to fix the state of the electronic device to one of the first state and the second state.
Claims10
An electronic device, comprising:
- a power supply;
- and
- a power supply circuit configured to
- perform a switching operation of periodically and alternately switching a state of the electronic device between a first state to supply power to a particular device and a second state to receive power from the particular device;
- and
- in response to a power supply switch being switched off al a time when the power supply circuit is supplying power to the electronic device and the switching operation is being performed, stop performing the switching operation of the state of the electronic device, so as to fix the state of the electronic device to one of the first state and the second state, even when the electronic device is not connected to the particular device.
A method executed by an electronic device, the method comprising:
- performing a switching operation of periodically and alternately switching a state of the electronic device between a first state to supply power to a particular device and a second state to receive power from the particular device;
- and
- in response to a power supply switch being switched off at a time when power is being supplied to the electronic device and the switching operation is being performed, stop performing the switching operation of the state of the electronic device, so as to fix the state of the electronic device to one of the first state and the second state, even when the electronic device is not connected to the particular device.
An electronic device, comprising:
- a power supply;
- and
- a power supply circuit configured to
- perform a switching operation of periodically and alternately switching a state of the electronic device between a first state to supply power to a particular device and a second state to receive power from the particular device during a period in which the electronic device is not connected to the particular device and the power supply circuit is supplying power to the electronic device;
- determine the state of the electronic device as one of the first state and the second state when the electronic device is connected to the particular device, and
- continue the state of the electronic device as the first state after the power supply switch of the electronic device is switched off, when the state of the electronic device is determined as the first state.
