Power saving operation for a media drive
View Patent ↗According to one embodiment, an information processing apparatus includes a media drive having a normal operation mode and a power saving operation mode in which less power is consumed than in the normal operation mode, a control module configured to control the media drive, and a determination module configured to shift, when it is determined that the control module does not execute data access to the media drive for a predetermined period, the media drive from the normal operation mode to the power saving operation mode.
1. An information processing apparatus comprising:
a media drive having a normal operation mode and a power saving operation mode in which less power is consumed than in the normal operation mode, the media drive being configured to shift from the normal operation mode to the power saving operation mode if access to the media drive is not executed for a first predetermined period; and
a determination module configured to determine whether data access to the media drive is not executed for a second predetermined period, and to interrupt an inquiry request, which is sent from an operating system to the media drive, in order to shift the media drive from the normal operation mode to the power saving operation mode if it is determined that the data access to the media drive is not executed for the second predetermined period,
wherein the determination module is further configured to return state information to the operating system if the determination module receives the inquiry request from the operating system while the media drive is in the power saving operation mode, the state information indicating a state in which the media drive is before the media drive shifts to the power saving operation mode.
2. The apparatus of claim 1 , wherein one or both of the information processing apparatus and the media drive have a predetermined button, and when the predetermined button is pressed, the media drive returns from the power saving operation mode to the normal operation mode.
3. The apparatus of claim 1 , further comprising a display module configured to execute, when the media drive is in the power saving operation mode, predetermined display.
4. A control method used in an information processing apparatus that includes a media drive having a normal operation mode and a power saving operation mode in which less power is consumed than in the normal operation mode, the media drive being configured to shift from the normal operation mode to the power saving operation mode if access to the media drive is not executed for a first predetermined period, the method comprising:
determining whether data access to the media drive is not executed for a second predetermined period;
interrupting an inquiry request, which is sent from an operating system to the media drive, in order to shift the media drive from the normal operation mode to the power saving operation mode if it is determined that the data access to the media drive is not executed for the second predetermined period; and
returning state information to the operating system if the inquiry request is received from the operating system while the media drive is in the power saving operation mode, the state information indicating a state in which the media drive is before the media drive shifts to the power saving operation mode.
5. The method of claim 4 , wherein one or both of the information processing apparatus and the media drive have a predetermined button, and when the predetermined button is pressed, the media drive returns from the power saving operation mode to the normal operation mode.
6. The method of claim 4 , wherein the information processing apparatus further includes a display module, and when the media drive is in the power saving operation mode, predetermined display is executed on the display module.
7. A computer-readable storage medium having stored thereon a computer program which is executable by a computer that includes a media drive having a normal operation mode and a power saving operation mode in which less power is consumed than in the normal operation mode, the media drive being configured to shift from the normal operation mode to the power saving operation mode if access to the media drive is not executed for a first predetermined period, the computer program controlling the computer to execute functions of:
determining whether data access to the media drive is not executed for a second predetermined period;
interrupting an inquiry request, which is sent from an operating system to the media drive, in order to shift the media drive from the normal operation mode to the power saving operation mode if it is determined that the data access to the media drive is not executed for the second predetermined period; and
returning state information to the operating system if the inquiry request is received from the operating system while the media drive is in the power saving operation mode, the state information indicating a state in which the media drive is before the media drive shifts to the power saving operation mode.
