Abstract
An information processing apparatus having a storage unit configured to store data, operated in a normal mode for supplying power to the storage unit or a power saving mode for preventing power supply to the storage unit, includes a determination unit configured to determine whether or not such a condition is established that the information processing apparatus is to be shifted from the normal mode to the power saving mode, and a measurement unit configured to measure an elapse time after a power source of the information processing apparatus is turned on.
Claims6
An information processing apparatus including a storage unit configured to store data, which operates in a normal mode of supplying power to the storage unit or a power saving mode of preventing power supply to the storage unit, the information processing apparatus comprising:
- a determination unit configured to determine whether a condition for shifting the information processing apparatus from the normal mode to the power saving mode is established;
- a measurement unit configured to measure an elapse time after a power source of the information processing apparatus is turned on;
- and
- a control unit configured to, when the determination unit determines that the condition is established, control the information processing apparatus to shift from the normal mode to the power saving mode at a first timing when a storage time obtained by subtracting a reference time from the elapse time by a number of times the information processing apparatus shifts from the normal mode to the power saving mode, is greater than a predetermined time which is less than the reference time, and further control the information processing apparatus to shift from the normal mode to the power saving mode when the storage time is less than the predetermined time, at a second timing which is later than the first timing.
A control method of an information processing apparatus including a storage unit configured to store data, which operates in a normal mode of supplying power to the storage unit or a power saving mode of preventing power supply to the storage unit, the control method comprising:
- determining whether a condition for shifting the information processing apparatus from the normal mode to the power saving mode is established;
- measuring an elapse time after a power source of the information processing apparatus is turned on;
- and
- controlling, when it is determined that the condition is established, the information processing apparatus to shift from the normal mode to the power saving mode at a first timing when a storage time obtained by subtracting a reference time from the elapse time by a number of times the information processing apparatus shifts from the normal mode to the power saving mode, is greater than a predetermined time which is less than the reference time, and further controlling the information processing apparatus to shift from the normal mode to the power saving mode when the storage time is less than the predetermined time, at a second timing which is later than the first timing.
