This post documents a reproducible behavior on the X728 V2.5 and the test methodology that isolates it to the X728 MCU. My hope is that other V2.5 users can confirm or refute, and that anyone with insight into the MCU's power-on logic can comment. | This post documents a reproducible behavior on the X728 V2.5 and the test methodology that isolates it to the X728 MCU.

The practical implication for anyone considering V2.5 for an unattended remote deployment: AON works in the specific scenario of "AC outage during operation, AC restored later" only if the battery has fully discharged in the interim (or is not installed). AON does not work after a clean software shutdown with batteries present — where, unfortunately, this is the configuration most users will actually deploy. | The practical implication for anyone considering V2.5 for an unattended remote deployment: AON works in the specific scenario of "AC outage during operation, AC restored later" only if the battery has fully discharged in the interim (or is not installed).
