Wireless noise is detected within a time period specifically held after a data packet is wirelessly communicated, where no data is purposefully wirelessly communicated during this time period. The time period may be an inter-frame space (IFS) period within which no data is to be wirelessly communicated, and that is a period waited for prior to accessing a wireless medium over which data is wirelessly communicated. One or more actions are performed to counteract the noise. The frequency at which a liquid crystal display is being driven may be decreased so that harmonics caused thereby that caused the noise are no longer within the wireless communication frequency range. An opposite-in-phase version of the noise may also or alternatively be combined with a signal when data is subsequently wirelessly received. The signal includes a data component and a noise component, the opposite-in-phase version of the noise canceling out the noise component.

Provided is an information processing apparatus that performs a desired process by a user while preserving a low consumption power state. The information processing apparatus comprises an electric power button for starting operation of an operating system when receiving an input from the user, a controller part for receiving an input to a switch other than the electric power button in an operation termination state in which the operation of the operating system is terminated, an execution part for executing a predetermined processing while preserving the operation termination state when the input to the switch is accepted by the controller part in the operation termination state.
