The program has instructions for performing the following steps: a) when a source of AC power fails, the UPS supplying AC power to the computer; b) the UPS notifying the computer to shut down; and c) just before the computer shuts down, the driver setting the RTC for a wake-up time at a prescribed time in the future.
