Lattepanda Delta 3 "auto power on" / AcPowerLoss - Power On doesn't work

Hello,

I made sure the RTC battery's charge is ok, it was not connected before.

In the documents you stated, that the Auto Power-On should work even if the RTC Battery is depleted..

I reset the BIOS Settings to Default Settings.

I set up the Auto Power On like here: https://docs.lattepanda.com/content/3rd_delta_edition/bios_Auto_power_on/

I made sure, that https://docs.lattepanda.com/content/3rd_delta_edition/bios_Deep_Sleep_EUP_Support/ is disabled

I Use Windows 10 on the Latte Panda.

I think it should take less then 30s from pressing SW1 to showing Latte Panda Logo.

I made sure, that the BIOS ROM: S70JR230-8G-A_20250416093826.bin of Build Date: 2025/4/16 is installed.

I checked the Serialnumber of the specific Latte Panda Delta 3 and its S70JR210.

Please let me know if you have further suggestions.

Best regards, Stefan
