Abstract: Aspects of the subject technology relate to a device including a pressure sensor to measure a pressure level in a port cavity. A port allows equalization of air pressure between the port cavity and an outside environment. A vent port within the port cavity allows equalization of air pressure between the port cavity and an internal volume of a housing of the device. A tool is used to activate a heat-generating component of the device while the port is obstructed for a predetermined time duration to enable detecting a sealing efficacy of the housing.
