@hpsaturn This should be the sound made by the SEN55 fan.Even if the device enters deep sleep, SEN55 is still active.The purpose of this is that the SEN55 can measure the ambient temperature more accurately.Ambient temperature measurements that are too high make some customers think the equipment is damaged.
