## Abstract

According to one embodiment, an information processing apparatus including a power source configured to supply power to an external device, including: a detector configured to detect a type of the external device; and a power supply configured to temporarily shut off supply of power to the external device from a first power supply mode and to supply power from a second power supply mode, when the detected type of the external device satisfies a first condition.

## Claims

### Claim 1

An information processing apparatus comprising a power source configured to supply power to an external device, comprising:
a detector configured to detect a type of the external device; and
a power supply configured to temporarily shut off supply of power to the external device from a first power supply mode and to supply power from a second power supply mode, when the detected type of the external device satisfies a first condition.

### Claim 2 (depends on 1)

The information processing apparatus of claim 1, wherein
the power supply temporarily shuts off supply of power to the external device after the information processing apparatus makes a transition to a non-operation state.

### Claim 3 (depends on 2)

The information processing apparatus of claim 2, wherein
the first condition is one of following three conditions, the external device is a non-wakeup device, the external device is compatible with the first supply mode, and a load current of the external device is larger than or equal to a prescribed value.

### Claim 4

A power supplying method of an information processing apparatus comprising a power source configured to supply power to an external device, comprising:
detecting a type of the external device; and
supplying power to the external device after temporarily shutting off supply of power from a first power supply mode and to supply power from a second power supply mode, when the detected type of the external device satisfies a first condition.
