Information processing apparatus and method of controlling information processing apparatus
View Patent ↗According to one embodiment, an information processing apparatus, includes a power management controller configured to perform power management of the apparatus, a power supply circuit configured to supply an operational power to components of the apparatus using power supplied from a rechargeable battery, and a power supply controller configured to control the circuit in response to a request from the power management controller. The power supply controller is coupled to two or more switches, and is configured to cause the power management controller to execute an initialization process in response to a first operation of the two or more switches.
1. An information processing apparatus, comprising:
a CPU:
a rechargeable battery;
a plurality of switches, each switch of the plurality of switches configured to cause the apparatus to execute a respective process;
a power management controller configured to perform power management of the apparatus in response to an operation of a power supply switch of the plurality of switches;
a power supply circuit configured to supply operational power to components of the apparatus using power from the rechargeable battery; and
a power supply controller configured to control the power supply circuit in response to a request from the power management controller, the power supply controller coupled to two or more switches of the plurality of switches and configured to cause the power management controller to execute an initialization process by controlling a reset signal to the power management controller in response to a first operation of the two or more switches.
2. The apparatus of claim 1 , wherein the power supply controller is configured to stop supply of the operational power from the power supply circuit to components other than the power management controller and the power supply controller.
3. The apparatus of claim 2 , wherein the power supply controller is configured to temporarily halt an internal clock to stop supply of the operational power from the power supply circuit to the components other than the power management controller and the power supply controller.
4. The apparatus of claim 1 , wherein the two or more switches comprise a first switch and a second switch, and the first operation comprises operating the first switch and the second switch simultaneously for a first period of time.
5. The apparatus of claim 4 , wherein the plurality of switches further comprise a third switch between the first switch and the second switch.
6. The apparatus of claim 1 , wherein the two or more switches comprise the power supply switch.
7. The apparatus of claim 1 , further comprising a keyboard and a keyboard controller configured to control the keyboard, the keyboard controller and power management controller mounted on a microcomputer, wherein
the power supply controller is configured to cause the keyboard controller to execute an initialization process by controlling the reset signal in response to the first operation on the two or more switches.
8. The apparatus of claim 1 , wherein the power supply circuit supplies the operational power to the power supply controller when the power supply circuit stops supplying the operational power to the CPU.
