Abstract: A power supply includes an adapter and a delay module. The adapter is operable to receive an input voltage and convert the input voltage into a first operation voltage to power a load controlled by a control unit. The adapter includes a filter capacitor configured to smooth the first operation voltage. The delay module detects the input voltage, and supplies a second operation voltage to the control unit when receiving the input voltage. The delay module continues supplying the second operation voltage to the control unit for a predetermined time period after the input voltage is no longer supplied to the adapter. As a result, the load operates for at most the predetermined time period and the filter capacitor discharges via the load after the input voltage is removed.
