Abstract
A method in a wireless communication device for diagnosing power supply failure in the wireless communication device is provided. The wireless communication device detects () an indication of power supply failure in the wireless communication device. When the indication of the power supply failure further indicates a non-active state of the wireless communication device or when the wireless communication device enters an error handling mode, the wireless communication device collects () diagnostic data from the PMU by means of a diagnostic engine () in the PMU. The wireless communication device then stores () the collected diagnostic data to a memory in the PMU. The data is related to the event resulting in the non-active state and/or to the latest event in a system of the wireless communication device or when the wireless communication device enters an error handling mode. Otherwise the wireless communication device stores () an indication indicating a potential power supply failure to the memory in the PMU. The wireless communication device then diagnoses () the power supply failure in the wireless communication device based on the diagnostic data and any one out of: —the data related to the event resulting in the non-active state and/or to the latest event in a system of the wireless communication device or when the wireless communication device enters an error handling mode, and—the indication indicating the potential power supply failure.
