Embodiments of the disclosed invention include a system and method for recording television content in the event of a power loss. More particularly it relates to high-density electronic devices. An operation powered by the capacitor is initiated, or not, by deriving from the time interval dT andor the voltage change dV, a total required time or a total required voltage for completing the operation, and comparing the total required time or total required voltage to a pre-determined necessary total time or predetermined necessary total voltage, respectively.
