Abstract

According to an aspect of the present invention, there is provided an information processing apparatus including: a connection port to which an external device is connected; a charge portion that performs a charge operation to the external device connected to the connection port in a first mode or in a second mode according to a charge control signal; an update portion that toggles a charge designating data between a first state corresponds to the first mode and a second state corresponds to the second mode; and a setting portion that sets the charge control signal in accordance with the charge designating data when the charge designating data is updated by the update portion.

Claims

1. An information processing apparatus comprising:

a connection port to which an external device is connected;

a charge portion that performs a charge operation to the external device connected to the connection port in a first mode or in a second mode according to a charge control signal;

an update portion that toggles a charge designating data between a first state corresponds to the first mode and a second state corresponds to the second mode; and

a setting portion that sets the charge control signal in accordance with the charge designating data when the charge designating data is updated by the update portion.

2. The information processing apparatus according to claim 1 further comprising:

a storing portion that stores the charge designating data when the charge designating data is toggled by the update portion; and

wherein the setting portion sets the charge control signal for the first mode or for the second mode in accordance with the charge designating data stored in the storing portion.

3. The information processing apparatus according to claim 1 further comprising:

a power supply portion that performs a power supply to the external device connected to the connection port; and

a start designation portion that performs a start designation for the power supply after the setting portion sets the charge control signal.

4. The information processing apparatus according to claim 3 further comprising:

a shut down control portion that controls the information processing apparatus to shut down after the start designation portion performs the start designating.

5. The information processing apparatus according to claim 1 further comprising:

a boot up control portion that controls the information processing apparatus to boot up; and

a regulation portion that controls the update portion and the setting portion to not be operated when the information processing apparatus is booted up.

6. The information processing apparatus according to claim 5,

wherein the storing portion stores a chargeability data indicating whether the charging operation to the external device is allowed;

and

wherein the regulation portion controls the update portion and the setting portion to not operate when the chargeability data indicates that the charging operation to the external device is not allowed.

7. The information processing apparatus according to claim 1,

wherein the update portion and the setting portion are operated when a POST (Power-on Self Test) is performed.

8. The information processing apparatus according to claim 1,

wherein the update portion and the setting portion operate before an operating system is operated.

9. The information processing apparatus according to claim 1,

wherein the connection port includes a USB port to which a USB device inconformity with a USB standard is connected.

10. The information processing apparatus according to claim 1,

wherein the first mode includes a rapid charge mode;

wherein the second mode includes a normal charge mode; and

wherein the setting portion sets the charge control signal to LOW for the rapid charge mode and sets the charge control signal to HIGH for the normal charge mode.

11. An information processing apparatus comprising:

a connection port to which an external device is connected;

a charge portion that charges the external device in a first mode or in a second mode according to a charge designating data; and

an update portion that toggles the charge designating data between a first state corresponds to the first mode and a second state corresponds to the second mode.
