An apparatus measures a dynamic power consumption in each of component devices at a time intervals and subtracts the sum of the dynamic power consumptions from a predetermined maximum value to obtain a dynamic margin. When a request for connecting an emergency device to a power supply is issued, the apparatus compares the rated power consumption in the emergency device with the dynamic margin. If the rated power consumption in the emergency device exceeds the dynamic margin, the apparatus selects, as a disconnectable device, a component device having an individual margin calculated by subtracting the dynamic power consumption from the rated power consumption is greater than an excess of power amount over the dynamic margin of the rated power consumption in the emergency device and the lowest priority. The apparatus issues an instruction to power the emergency device if the rated power consumption in the emergency device is less than or equal to the dynamic margin, issues an instruction to power off the disconnectable device if the rated power consumption in the emergency device exceeds the dynamic margin, and issues an instruction to power on the emergency device after the power-off of the disconnectable device is confirmed.

The method, terminal and computer program product of the present invention are capable of adjusting the power consumption of short-range communication transceivers, such as RFID, IR transceivers or the like. Energy management of the transceiver is achieved by limiting activation of the transceiver to periods of user-interface illumination. The transceiver, therefore, uses less power because it is only activated by an intentional gesture by the user, i.e., a gesture that will initiate the illumination of a user-interface. In addition, the user of terminal is aware, via observation of the illumination, that the terminal is in an active transceiver reading state and, thus, the invention provides for a safe environment in which inadvertent reading of tags or data communication is lessened.
