The X728 is an advanced uninterruptible power supply expansion board for all current models of the Raspberry Pi using a 40 pin header.

It provides 5.1V ~~6000mA~~ Power Backup for even the most demanding Raspberry Pi set ups, intelligent and safe power management, safe shutdown，AC power loss/ power adapter failure detection , auto power-on, full poweroff from software, battery capacity reading, and a real- time clock(RTC), buzzer alarm.

It provides 5.1V 5000mA Power Backup for even the most demanding Raspberry Pi set ups, intelligent and safe power management, safe shutdown，AC power loss/ power adapter failure detection , auto power-on, full poweroff from software, battery capacity reading, and a real- time clock(RTC), buzzer alarm.

The X728 reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications. The X728 can also be used with the [[X825]]/[[X828]]/[[X829]] (2.5" HDD/SSD Shield) and [[X857]]/[[X862]]/[[X872]] (MSATA/M.2 SSD shield) for safe data backup.

</div>

Q12: Simulate power outage and reconnection scenario. Why does the Raspberry Pi fail to auto boot after unplugging and reconnecting the power supply?

</div>

A: In the process of X728 auto power-on test, the Raspberry Pi fails to auto boot after power reconnection due to '''<span class="tb_red">incomplete power discharge</span>'''. This issue usually occurs when cutting power by unplugging the power adapter, while it will not happen if you disconnect the USB port directly.

:'''1. Cause'''

:Residual charge remains in the power adapter after disconnection, keeping voltage present at the X728 input terminal. Reconnecting power immediately fails to fully cut off the circuit, hence the auto power-on function cannot be triggered.

:'''2. Discharge Completion Check (refer to the picture)'''

:Measure the voltage on the X728 DC jack input pads. The auto power-on function will be invalid if the reading is non-zero. Full discharge is achieved when voltage falls to zero, which usually takes more than 30 seconds. Discharge time varies depending on different power adapters.
