The system for simplified operating system shutdown enables the execution of the required operating system shutdown sequence without requiring the use of a monitor, keyboard, and mouse. This is accomplished by equipping the printed circuit board with a simple switch and an indicator device to provide the user interface to execute the operating system shutdown process. The user operates the switch, which activates the system for simplified operating system shutdown to initiate the required operating system shutdown process. The system for simplified operating system shutdown activates the indicator device in a first mode to notify the user that the shutdown process is now executing. The system for simplified operating system shutdown generates a message, which message is transmitted to the processor. This message comprises a system call for a shutdown and restart. No indication is provided by the operating system to indicate the successful completion of the shut down process, but in the restart process, the operating system generates predetermined POST codes, which are detected by the system for simplified operating system shutdown and used to hold the processor in a reset state. The system for simplified operating system shutdown then activates the indicator device to a second mode to indicate to the user that the operating system is shutdown and the circuit board can be removed from the circuit pack carrier.
