Patent ID: 8176346

Claim:
An information processing apparatus comprising: a storage unit configured to store data; a supply unit configured to supply electric power to the storage unit; a determination unit configured to determine whether to cause the information processing apparatus to operate in a power saving mode; a measuring unit configured to measure an elapsed time until the determination unit determines to cause the information processing apparatus to operate in a power saving mode; and a control unit configured to control the supply unit to decrease electric power supplied from the supply unit to the storage unit at a timing determined based on the elapsed time and a predetermined reference time, in case that the determination unit determines to cause the information processing apparatus to operate in a power saving mode; and a recording unit configured to record a number of increment times when the power supply from the supply unit to the storage unit is increased, wherein the control unit is configured to control the supply unit to decrease electric power supplied from the supply unit to the storage unit at a first timing if the elapsed time is equal to or longer than a time obtained by multiplying the reference time by the number of increment times, and is configured to control the supply unit to decrease electric power supplied from the supply unit to the storage unit at a second timing that is later than the first timing if the elapsed time is shorter than the time obtained by multiplying the reference time by the number of increment times.
