An information processing apparatus includes a power processor, an interface, a first detector that detects at least one of a voltage value and a current value on an electric power line which connects the power processor and the interface, a second detector that detects at least one of a voltage value and a current value on the electric power line, a switch that switches a supply of electric power supplied from the interface to an outside, and a controller. The controller controls the switch to restrict the electric power supplied from the interface to an outside in a case where at least one of a detection value of the first detector and a detection value of the second detector is equal to or greater than a threshold value.

An electronic device that is able to operate by receiving a power supply from a host device through a Universal Serial Bus (USB). The electronic device acts as a first sink device and is connected to a second sink device that is able to operate by receiving a power supply from the host device through the USB and the connection to the first sink device. Each of the first sink device and the second sink device is provided with a CC terminal that obtains power supplying capability information from the host device, a pull-up or pull-down resistor connected to the CC terminal, and a GND terminal that grounds a circuit of the CC terminal and the pull-up or pull-down resistor. The electronic device changes a state of grounding of the pull-up or pull-down resistor to the GND terminal, in one of the first sink device and the second sink device.

To provide an apparatus for performing operation relating to switching of a power switch while power is supplied from an auxiliary power source, the apparatus acquires switch information indicating whether the power switch is in an on state from a BMU of a battery pack and determines whether to limit processing based on a user instruction based on the acquired switch information.

An image forming apparatus includes a housing, a door, an inlet, a primary power source, a secondary power source, a primary interlock switch, and a secondary interlock switch. The housing has an opening. The door is hinge-coupled to the housing by a hinge, and opens and closes the opening. The inlet is provided near the hinge. The secondary power source is provided farther from the inlet than the primary power source. The primary interlock switch is provided on a primary electric circuit between the inlet and the primary power source, and is turned off when the door is opened. The secondary interlock switch is provided on a secondary electric circuit between the primary power source and the secondary power source, and is turned off when the door is opened. The primary interlock switch is disposed closer to the inlet than the secondary interlock switch.
