motherboard B450 Pro4 Restore on AC/Power loss not working, when i select "Always on". If I unplug the power supply, the PC will not turn on. Although this item is set correctly. Firmware: 3.60 (currently the latest version). I did not reflash myself. Already wrote in support. They do not answer. This feature is very important to me. Photos:

I agree, a PC should work even if no power is supplied...  Sorry, i'm joking. You obviously forgot to write that you plug in the PSU after that. First: If you are using Windows 10, you should uncheck the "Turn on fast startup": Step 1. Open the Power Option item in control panel. Step 2. Click the Choose what the power button do link. Step 3. Click Change settings that are currently unavailable. Step 4. Clear the Turn on fast startup (recommend) check box. Step 5. Click Save changes. That was the solution for a user in another forum. Second: I do not use "Restore on AC/Power loss", but in my bios a second item is available, maybe you should check that: Advanced\AMD CBS\FCH Common Options\AC Power loss Options Ac Loss Control And here is a thread for another board with that problem: http://forum.asrock.com/forum_posts.asp?TID=12059&title=fatal1ty-b450-gamingitx-restore-on-ac-power-loss ------------- Asrock Fatal1ty X370 Professional Gaming Offline Under test: MSI X570_MEG_ACE | AMD Ryzen 9 3900X | Scythe Mugen5 | 2x16GB F4-3200C14D-32GTZ@3466 | ASUS GeForce GTX 1080 Ti FE |

BTW: I just have seen in the first screenshot, that you put your RAM stick in the slot A1. You should use A2! This can be important, because of the termination of the RAM bus. It is also mentioned in the manual. ------------- Asrock Fatal1ty X370 Professional Gaming Offline Under test: MSI X570_MEG_ACE | AMD Ryzen 9 3900X | Scythe Mugen5 | 2x16GB F4-3200C14D-32GTZ@3466 | ASUS GeForce GTX 1080 Ti FE |

Thanks for trying to help, Ray62. I tried to do everything you said, but it didnt help me. The support service answered me and gave me this version of the BIOS. Then everything worked!
