description A method, apparatus, and combination for reducing acoustical noise at start-up of a device is disclosed. The method includes the steps of determining an internal temperature of the device, and unlatching an actuator of the device based on the determined internal temperature of the device, by steps for unlatching the actuator of the device. The apparatus includes a thermistor providing a resistance value to a controller that selects an unlatch process based on the resistance value of the thermistor, and an unlatch procedure programmed into the controller executing the selected unlatch process. The device combination includes a base deck supporting an actuator confined by a magnetic latch for periods of inactivity, and unlatched from the magnetic latch for periods of activity by steps for unlatching the actuator.
