Abstract
The present invention relates to a portable information apparatus which can realize electrical power for a longer period of time. Under the condition that the suspending mode is set, when an exclusive key is manipulated, a switch monitoring circuit detects this condition and issues an interruption to the CPU. In this timing, the CPU supplies the necessary electrical power to the CD-ROM controller, CD-ROM drive and audio circuit which are required for reproduction of CD. Thereby, a CD can be reproduced under the suspending mode.
Claims6
An information processing apparatus, comprising:
- a media drive configured to reproduce data from a storage medium;
- a first operation key configured, when activated, to change a state of said information processing apparatus from a first operating state to a second operating state, said information processing apparatus configured to execute a predetermined application program when the information processing apparatus is in the first operating state, and said information processing apparatus is configured to stop executing when said information processing apparatus is in the second operating state, the second operating state being (1) a suspension mode and (2) a low power consumption mode where supply of power to the information processing apparatus is lower than power supply to the information processing apparatus during the first operating state;
- a second operation key configured, when activated, to change a state of said information processing apparatus from the second operating state to a third operating state, said media drive supplied electrical power during said third operating state, and said information processing apparatus prohibited from executing the predetermined application during the third operating state;
- and
- a third operation key configured, when activated during said second operating state, to change the state of said information processing apparatus from the second operating state to the first operating state.

A method for operating an information processing apparatus, comprising:
- activating a first operation key to change a state of said information processing apparatus from a first operating state to a second operating state, said information processing apparatus configured to execute a predetermined application program when the information processing apparatus is in the first operating state, and said information processing apparatus is configured to stop executing when said information processing apparatus is in the second operating state, the second operating state being (1) a suspension mode and (2) a low power consumption mode where supply of power to the information processing apparatus is lower than power supply to the information processing apparatus during the first operating state;
- activating a second operation key to change a state of said information processing apparatus from the second operating state to a third operating state, supplying a media drive of the information processing apparatus electrical power during said third operating state, and prohibiting said information processing apparatus from executing the predetermined application during the third operating state;
- and
- activating a third operation key during said second operating state to change the state of said information processing apparatus from the second operating state to the first operating state.
1 more element
An information processing apparatus, comprising:
- means for reproducing data from a storage medium;
- means, when activated, for changing a state of said information processing apparatus from a first operating state to a second operating state, said information processing apparatus configured to execute a predetermined application program when the information processing apparatus is in the first operating state, and said information processing apparatus is configured to stop executing when said information processing apparatus is in the second operating state, the second operating state being (1) a suspension mode and (2) a low power consumption mode where supply of power to the information processing apparatus is lower than power supply to the information processing apparatus during the first operating state;
- means, when activated, for changing a state of said information processing apparatus from the second operating state to a third operating state, said means for reproducing data supplied electrical power during said third operating state, and said information processing apparatus in a waiting condition prohibited from executing the predetermined application during the third operating state;
- and
- means, when activated during said second operating state, for changing the state of said information processing apparatus from the second operating state to the first operating state.
