INFORMATION PROCESSING APPARATUS AND METHOD OF CONTROLLING POWER THEREOF
First Claim
1. An information processing apparatus comprising:
- a backup control unit configured to control processing for backing up data that has been stored in storage means;
a backup power supply charged by a main power supply, said backup power supply supplying power to the storage means, in a state in which the storage means is not supplied with power from the main power supply, in order that backup processing by said backup control unit will be performed;
a timer configured to count power-supply time, which is a length of time a voltage equal to or greater than a prescribed voltage for assuring operation of the storage means is supplied by said backup power supply in order that backup processing will be performed;
a determination unit configured to determine whether the power-supply time counted by said timer is shorter than length of a reference backup time for assuring completion of the backup processing; and
an alert unit configured to notify of result of the backup processing in accordance with result of the determination made by said determination unit.

Abstract
Backup control means controls processing for backing up data in storage means. In a state in which the storage means is not being supplied with power from the main power supply, a backup power supply supplies power to the storage means in order that backup processing by the backup control means will be performed. A timer measures power-supply time, which is the length of time the backup power supply supplies a voltage equal to or greater than a rated voltage to the storage means in order that backup processing will be performed. Determination means determines whether the power-supply time counted by the timer is shorter than length of a reference backup time. Notification of result of backup processing is given by alert means in accordance with the result of the determination made by the determination means.

10. A method of controlling power of an information processing apparatus having a backup control unit configured to control processing for backing up data that has been stored in storage means, and a backup power supply charged by a main power supply, the backup power supply supplying power to the storage means, in a state in which the storage means is not supplied with power from the main power supply, in order that backup processing by the backup control unit will be performed, said method comprising:
-
counting power-supply time, which is a length of time a voltage equal to or greater than a prescribed voltage for assuring operation of the storage means is supplied by the backup power supply in order that backup processing will be performed; determining whether the power-supply time measured at said power-supply time counting step is shorter than length of a reference backup time for assuring completion of the backup processing; and notifying of result of the backup processing in accordance with result of the determination made at said determining step. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
