PC auto-starts when power is applied

tell me if you know

Is there a setting in the BIOS for recovery when AC power is lost (PC auto-starts when power is applied)?

2

Chipset → PCH-IO Configuration → State After G3: S5 State

I don’t have this device but that’s where it is on CoreBook X, and in AMI BIOS in general. Assuming you don’t want it to start automatically, choose S5 there.

Thank you

I’ll try it after work.

And? What’s the result?

Chipset → PCH-IO Configuration - checked - there is no such or similar item.

As I said, I don’t have this exact device but that’s the name for the setting responsible for this, and it should be there somewhere, possibly in another submenu.

If you can’t find it and don’t want to go through all the menus looking for it, alternatively you can dump your BIOS and extract the IFR data using a tool such as this:

Then you’ll have a text file listing all the settings, which can be searched for the keyword.

Of course maybe someone who has this device can chip in and provide a better answer but that’s the best I can do.

If your PC turns on automatically when power is applied, it’s likely due to a BIOS/UEFI setting like “Restore on AC Power Loss” or “Power On After Power Failure.” You can disable this in the BIOS menu.
