Information processing apparatus, control method of information processing apparatus, and program

A method of controlling an information processing apparatus, comprising a CPU (fig. 1, 102) configured to operate at least in any of a first operation mode and a second operation mode higher in operation performance than the first operation mode; and a switching unit (fig.1, 104) configured to, when starting an OS or an application S110 whilst in the first operation mode, switch the state of the CPU to the second operation mode S112, and subsequently when a predetermined condition is met, switch the state of the CPU to the first operation mode S114. The operation mode may also be switched when a change in use form has been detected S104, the use form can be distinguished by shape. The predetermined condition can be based on the time elapsed or the use rate of the CPU. The switch to the second operation mode may be to reduce or stop a background application, and may occur when starting the BIOS, or based on the file type being a program execution file. The first operation mode may also limit the temperature increase of the system.
