摘要:
An energy consumption component for a network system which communicates with another component includes a communication unit to receive information related to power supply from the another component, a power management unit to receive the information related to power supply and to determine whether the energy consumption component is operable in a normal capacity or in limited capacity, and a user interface including a display unit to display at least one usable function. The display unit indicates that the at least one usable function is usable based on the information related to power supply.
