Data processing apparatus and its power failure processing method, and a power failure processing program

摘要

PPROBLEM TO BE SOLVED: To reliably shut down a system even when a main power source fails. PSOLUTION: When a failure of the main power source is detected, it is determined whether there is any unsaved data. If an automatic shut-down function is enabled and no unsaved data is determined when a failure of the main power source is detected, a first message indicating that the automatic shut-down function is enabled and there is no unsaved data, is displayed on a display. If the automatic shut-down function is enabled and there is unsaved data when a failure of the main power source is detected, a second message indicating that the automatic shut-down function is enabled and there is unsaved data, is displayed on the display.
