Abstract

An information processing apparatus, having a hibernation state, includes a hibernation controller that stores information required to resume the information processing apparatus from the hibernation state to an arbitrary operational state when the information processing apparatus is shifted from the arbitrary operational state to the hibernation state and that turns off the information processing apparatus; a determiner determining whether the information processing apparatus is started up from the hibernation state when the information processing apparatus is turned on after the information processing apparatus is turned off by the hibernation controller; and a resume controller returning the information processing apparatus from the hibernation state to the arbitrary operational state based on the required information when the determiner determines that the information processing apparatus is resumed from the hibernation state.

Claims

1. An information processing apparatus having a hibernation state, the information processing apparatus comprising:

means for storing data required to resume a state of information processing apparatus from the hibernation state to an arbitrary operational state when the state of the information processing apparatus is shifted from the arbitrary operational state to the hibernation state;

means for turning off the information processing apparatus after the state of the information apparatus is shifted to the hibernation state;

means for determining whether the state of information processing apparatus is resumed from the hibernation state when the information processing apparatus is turned on after the information processing apparatus is turned off; and

means for resuming the state of the information processing apparatus from the hibernation state to the arbitrary operational state based on the required data when the means for determining determines that the state of the information processing apparatus is resumed from the hibernation state.

2. The information processing apparatus according to claim 1,

wherein the state of the information processing apparatus is booted based on a normal boot-up sequence when the means for determining determines that the state of the information processing apparatus is not resumed from the hibernation state.

3. The information processing apparatus according to claim 1,

wherein the means for storing and the means for turning off are included in an operating system of the information processing apparatus.

4. The information processing apparatus according to claim 1, wherein the means for determining is included in a BIOS.

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

a first device which has first operating system;

a second device which has second operating system;

means for selecting one of the first device and the second device; and

wherein one of the first operating system and the second operating system in the selected device is started up when the state of the information processing apparatus resumes from the hibernation state to the arbitrary operational state.

6. A method of starting up an information processing apparatus having a hibernation state, the method comprising:

storing information required to resume the information processing apparatus from the hibernation state to an arbitrary operational state when the information processing apparatus is shifted from the arbitrary operational state to the hibernation state;

turning off the information processing apparatus;

determining whether the information processing apparatus is resumed from the hibernation state when the information processing apparatus is turned on after the information processing apparatus is turned off; and

resuming the information processing apparatus from the hibernation state to the arbitrary operational state based on the required information when it is determined in the determining step that the information processing apparatus is resumed from the hibernation state.

7. The method of starting up the information processing apparatus according to claim 6,

wherein the information processing apparatus is booted up based on a normal boot-up sequence of the information processing apparatus when it is determined in the determining step that the information processing apparatus is not resumed from the hibernation state.

8. The method of starting up the information processing apparatus according to claim 6,

wherein the information processing apparatus further includes a plurality of devices capable of providing a plurality of operating systems,

wherein a device, among the plurality of devices, whose operating system is used to start up the information processing apparatus is stored in a startup device storage before the information processing apparatus is turned off, and

wherein the operating system in the device stored in the startup device storage is started up to resume the information processing apparatus to the arbitrary operational state when it is determined in the determining step that the information processing apparatus is resumed from the hibernation state.

9. A startup program of an information processing apparatus having a hibernation state, the startup program causing a computer to execute the steps of:

storing information required to resume the information processing apparatus from the hibernation state to an arbitrary operational state when the information processing apparatus is shifted from the arbitrary operational state to the hibernation state;

turning off the information processing apparatus;

determining whether the information processing apparatus is resumed from the hibernation state when the information processing apparatus is turned on after the information processing apparatus is turned off; and

resuming the information processing apparatus from the hibernation state to the arbitrary operational state based on the required information when it is determined in the determining step that the information processing apparatus is resumed from the hibernation state.

10. The startup program of the information processing apparatus according to claim 9,

wherein the startup program causes the computer to execute a step of booting up the information processing apparatus based on a normal boot-up sequence of the information processing apparatus when it is determined in the determining step that the information processing apparatus is not resumed from the hibernation state.

11. The startup program of the information processing apparatus according to claim 9,

wherein the information processing apparatus further includes a plurality of devices capable of providing a plurality of operating systems, and

wherein the startup program causes the computer to execute a step of storing a device, among the plurality of devices, whose operating system is used to start up the information processing apparatus in a startup device storage before the information processing apparatus is turned off;

and a step of starting up the operating system in the device stored in the startup device storage to resume the information processing apparatus to the arbitrary operational state when it is determined in the determining step that the information processing apparatus is resumed from the hibernation state.
