Claim:
An information processing equipment that carries out a communication path establishment processing at the time when a power source is turned on, the information processing equipment comprising: a connector that is connected with a communication line based on the needs; a transmission/reception mechanism that transmits/receives data through said communication line connected to said connector; a connection status deciding unit that decides whether said communication line has been connected to said connector or not; and a control unit that controls said transmission/reception mechanism to carry out an initialization processing for establishing a communication path connected to said communication line, wherein said control unit controls not to carry out the initialization processing when it has been confirmed that said communication line has not been connected to said connector as a result of the decision made by said connection status deciding unit, and wherein said transmission/reception mechanism has a plurality of operation modes having different levels of power consumption, and when the initialization processing is not carried out based on the confirmation that said communication line has not been connected to said connector as a result of the decision made by said connection status deciding unit, said control unit shifts said transmission/reception mechanism to an operation mode in which power consumption is lower.
