An uninterruptible power supply unit can communicate with a computer being in a suspend or sleep state. The uninterruptible power supply unit includes a first unit which transmits a first signal for informing the computer that the power supply from the commercial power is stopped via a first communication interface; and a second unit which transmits a second signal for activating the computer from the suspend or sleep state via second communication interface, the second unit being in an active state when the computer is in the suspend or sleep state.
