Lattepanda 3 Delta - Auto Power On

Question

Hi,

We recently bought a LattePanda 3 Delta and are powering it through the JST PH2.0-4Pin connector. We have set ACPowerLoss to "Power On" in the BIOS.

When we power it through the JST connector, it turns on automatically without shorting the SW and AUTO pins.

When the RTC battery has sufficient power, the board can automatically power on when connected to a power source because you set ACPowerLoss to "Power On" in the BIOS.
However, when the RTC battery is low, this setting will not work, and you will need to short the SW and AUTO pins.

Therefore, to ensure the reliability of the automatic power-on feature, both of the above settings are necessary.
