According to one embodiment, an information processing apparatus including a suspension/resume function includes a bus controller which controls a bus capable of transmitting data at a first transmission speed or a second transmission speed lower than the first transmission speed, a storage module which stores setting information for limiting a data transmission speed of the bus to the second transmission speed, an initializing module which initializes the bus controller so as to limit the data transmission speed of the bus to the second transmission speed if the setting information is stored in the storage module when the apparatus is activated or returned from a suspended state, and a controller which stores the setting information into the storage module and makes the apparatus transit to the suspended state and return from the suspended state, when the transmission speed of the bus is limited to the second transmission speed.
