Abstract: An information processing apparatus has a first processor, a memory, and a second processor. The memory and second processor are supplied with power from a power supply by a first supplying operation. The first processor is supplied with power from the power supply by a second supplying operation that starts when a startup instruction is inputted during the first supplying operation, executes a series of processes that precedes booting of an operating system, and that outputs a code indicating an execution step in the series of processes to the memory. The second processor outputs the code stored in the memory from an output port at least while the first supplying operation is being performed before inputting of a startup instruction. The debug board has a display unit and a third processor. The third processor receives the code from the output port and displays code-based information on the display unit.

Abstract: An information processing apparatus includes a control unit and a peripheral device, which includes a relay device, a computational processing device group, and a power supply unit. The peripheral device is connected to a host apparatus. The relay device relays communication via an expansion bus. The computational processing device group includes a plurality of computational processing devices individually connected to the expansion bus. The power supply unit is a power supply for the operation power. The control unit executes control over supplying of the operation power to the host apparatus and the peripheral device, monitors an operation state of a power switch, and is operable when a long press of a predetermined time or longer of the power switch has been detected, to shut off the operation power being supplied to the host apparatus and the peripheral device in a predetermined order.

Abstract: An information processing apparatus includes: a first control device that controls, in accordance with an operation mode, power reception/delivery from/to an external device connected to the information processing apparatus; a battery that is recharged by an external power supply or the external device; a second control device that acquires a power supply state of the information processing apparatus; and a third control device that determines whether power is being delivered from the external power supply to the information processing apparatus; and sets the operation mode of the first control device to a first mode based on the power supply state and on a result of the determination. The first mode is an operation mode in which the power reception alone is enabled between the power reception from the external device and the power delivery to the external device.

Abstract: An information processing system includes a first information processing device, a second information processing device, and a relay device connected to the first/second information processing devices over different buses. The first information processing device updates firmware of the power control microcomputer and transmit, to the power control microcomputer, a reactivation instruction signal after the firmware is updated. The power control microcomputer: executes reactivation of the power control microcomputer when the reactivation instruction signal is received from the first information processing device; determines whether or not the executed reactivation is reactivation that is executed immediately after the firmware update; and supplies the operation voltage to the first information processing device when the power control microcomputer determines that the executed reactivation is reactivation immediately after the firmware update.

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.
