ABSTRACT:
A peripheral device input-initiated resume system for a combined hibernation system and back-up power supply for a computer comprises a keyboard controller for inputting an appropriate signal to the operating condition based on the key selected by a user, a power management system for outputting a wake-up signal if the signal is inputted from the keyboard or other input devices, a data back-up power unit for supplying DC voltage in case the power is cut-off suddenly or a user does not use the computer for a predetermined time, a power supplying unit in which a switching-mode power supply SMPS converts the external source AC power at line voltage into DC power at a desired voltage and supplies that power to each device on the main board of the computer, thereby retrieving the previous work again by cutting off power of all devices, once the power is off or when a user does not use the computer for a predetermined time, and supplying the additional power only to the MICOM(Micro Computer) or keyboard controller in the state that a hibernation mode is performed. Then the system repeats supplying power if a signal is input again by a user, and consequently helps a user to use the computer more easily with this hibernation state by retrieving the work to the previous state.
