GUI for PC auto-shutdown

This paper presents the development of graphical user interface (GUI) for auto-shutdown of personal computer using Microsoft Visual Basic 6.0. The software monitors the status of power supply of the personal computer through peripherals device such as uninterrupted power supply (UPS). When the power goes out, the UPS supplies the power to the PC for a limited period of time. Before the UPS reaches its limit it sends a signal to the PC through RS-232 serial port and the software detects the signal and executes for saving all the programs opened by user and give the PC auto-shutdown. An application programming interface (API) function is used in the Visual Basic program. The software developed in this project is capable of saving all the programs opened by the users and shutdown the PC safely when the power goes out. It saves from corruption of all software and hardware in the PC.
