Restore on AC/Power Loss doesnt work on my Asrock Fatal1ty B450 Gaming K4. I have set this setting in BIOS to always on but PC doesn't boot up once it gets back to power. Motherboard lights up but PC doesn't start up. Any ideas? *Have disabled Turn on Fast Startup on Windows 10 OS. |

| Ok...tried rolling back to 3.20 version of BIOS with this option being in South Bridge Menu. And it works. So...Asrock, in latest BIOS versions this function is BROKEN. Fix it please... |

If you want that to be fixed you have to contact Asrock support. And if somebody shall understand here why it is working with the 3.20 version of BIOS, you should name it! You mean this entry?

Nope, the one that is in Advanced > South Bridge Menu. Anyways. I contacted Asrock and they replicated the issue SUPER FAST and confirmed that it is bugged. It will be fixed in the next version of their BIOS 3.8(something). |
