Hi everyone,
i have purchased a number of these motherboards: J3355B-ITX

And this problem occurs on all motherboards that i have purchased.

The problem is this: when there are power surges on the customer's house (electricity goes out and then comes back), the computer does not restart by itself (despite the dedicated property in the bios active [Restore on AC/power lost]), or in any case it does not start correctly.
Instead of booting properly, the message "CMOS Date/Time Not Set" appears (image 1).

If I abruptly turn off the power (by unplugging the power cord), and then plug the cord back in, the computer always starts up fine.
The problem only occurs with power surges.

Other useful information:
- bios is update (P1.90)
- the cmos battery is charged (3.23 volts)
- once the CMOS error occurs, there is no way to restart the computer (without pressing F1). If I turn the computer off and on again, the CMOS error still pops up. If instead I disconnect the CMOS battery and reconnect it (the same CMOS battery), the computer restarts correctly

I have looked in the BIOS settings, but have not found any way to disable this BIOS error, and thus allow the customer's computer to reboot properly without having to press the F1 button.

Thank you
