A circuit in an electronic device, such a computer, printer, copier and the like, evaluates a duration of a power cycle of the electronic device. The circuit, upon detection of a sufficiently brief power cycle, selects a shortened boot-up sequence to expedite recovery of the electronic device into an operational state. The circuit includes a short-power cycle detector which retains a power cycle status for use in evaluation of the power cycle duration and a charging circuit for updating the power cycle status. Timing elements for providing isolation of the charging circuit during evaluation and the updating of the power cycle status during an operational state are also presented.
