Auto Power on is not stable

#1
Hi,

I have set my Minix Neo Z83-4 to power on automatically when the 12V input is active.

In the Bios I set the automatic power on to [Always On], press F4 to save and exit, then Choose [YES].

It will now start automatically if I turn the power off and back on again. It will do this for one or two cycles, and then fail. It now needs a manual push of the power button to start it. Going back to the BIOS, the auto power has been reset to OFF.

Is there any way to make this a permanent change? I am using the computer to run an astronomical observatory and need to be able to switch the computer on and off remotely.

Maybe you have changed many options on the bios and it is not working as it should be.

Try this:
1.Go to bios and set bios with default settings
2.Save and exit
3.go to bios again and set auto power again to always
4.save and exit

Have reset bios to default saved and exited. then re-entered bios and set AC Power On to [Always On] before saving and exiting again.

If I go back to the bios at this point the change has been saved.

However, the first time I interrupt the power supply it boots OK, the second time nothing happens until I push the power switch.

I have repeated this cycle three times.

The bios details are as follows:

Bios vendor - American Megatrends
Core version - 5.0111
Project version - CHT0A 1.6 x64

Any other suggestions?

Updated the BIOS but problem remains. Can you direct me to instructions for replacing the CMOS battery, I can't find it mentioned anywhere.
