Are you using the sd_power_system_off() function?<br /> Note that the device is not OFF when you put it in system off mode, it is put in a low power/deep sleep state, where it can only be waked up by reset, GPIO, NFC field or LPCOMP module.</p> <p><a href="https://devzone.nordicsemi.com/question/120672/long-press-to-wake-up/">This case</a> might provide some useful information.<br /> As Hung and Endnode said, there is no clock running in SYSTEM OFF, so you will not be able to detect &quot;long press&quot;.</p> <p>Best regards,<br /> Joakim</p><div style="clear:both;"></div>
