Abstract
Disclosed is a process and apparatus for controlling a power shutdown of an electrical device. The operations for controlling a power shutdown include determining a value MAX indicating a maximum number of safe power-on transitions that could have been experienced by the electrical device prior to a specified date. In addition, a threshold value P indicating a number of permissible power-on transitions prior to the specified date is determined from the value MAX. A value N indicating a number of power-on transitions that have occurred prior to the specified date is then determined. The power shutdown is inhibited if the value N is greater than the threshold value P, and otherwise allowed.
