Information processing apparatus with power saving mode and method for controlling information processing apparatus

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 control unit configured to, in case that the determination unit determines to cause the information processing apparatus to operate in the power saving mode, control the supply unit to decrease electric power supplied from the supply unit to the storage unit at a first timing if a condition that an elapsed time is equal to or longer than a time obtained by using multiplying of a reference time by the number of increment times is satisfied, and 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 a condition that the elapsed time is shorter than the time obtained by using multiplying of the reference time by the number of increment times is satisfied,
• wherein the elapsed time is time until the determination unit determines to cause the information processing apparatus to operate in a power saving mode, and the number of increment times is the number of times when the power supply from the supply unit to the storage unit is increased.
