Embodiment Construction

[0015] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016]

[0017] (basic structure and operation)

[0018] FIG. 1 is a block diagram showing an example of a basic structure of an information processing device according to an embodiment of the present invention. FIG. 2 is a flowchart showing an example of a basic operation in the ON state of the information processing device according to the embodiment of the present invention. The steps of the flowcharts in Figs. 2, 4, and 5 can be replaced by circuit blocks, respectively. Therefore, all steps in the flowchart can be redefined as modules respectively.

[0019] An information processing device 1 according to an embodiment of the present invention serves as a basic structure. As shown in FIG. 1 , an information processing apparatus 1 has: a control unit 11; a nonvolatile memory 12 (such as a flash memory or HDD (Hard Disk Drive)) connected to the con...

Abstract

The invention provides an information processing apparatus and a power supply control method for the information processing apparatus. According to one embodiment, there is provided an information processing apparatus including a power supply unit which outputs a voltage when an external AC current is supplied to the power supply unit, a nonvolatile memory, a volatile memory, and a control unit to which the nonvolatile memory and the volatile memory are connected and which performs control to transfer a program from the nonvolatile memory to the volatile memory when the voltage is supplied from the power supply unit to the control unit.

Description

technical field [0001] One embodiment of the present invention relates to a power supply of an information processing device and a power control method for the information processing device. Background technique [0002] In recent years, various information processing devices have been developed and spread. Many additional functions for information handling devices are desired. In particular, in a power supply unit of an information processing apparatus, means for starting an OS (Operating System) program at high speed is desired. [0003] In Patent Document 1 (Japanese Patent Application Laid-Open Publication No. 2006-79468), at the moment when the standby mode is set, the content is also recorded on the HDD (Hard Disk Drive). In this way, when the AC power is continuously supplied during the standby mode, the program can be started at high speed by using the contents in the memory. In this publication, when the AC power is interrupted, the content in the HDD is copied, ...
