Thanks Ray. I did a search before making this thread but missed that somehow. Unfortunately, I don't have a PS/2 keyboard. Hopefully, someone from ASRock sees that and add the feature back.]]> Sun, 04 Aug 2019 22:37:58 +0000 https://forum.asrock.com/forum_posts.asp?TID=12097&PID=66054&title=no-turnonafterpowerconnect-in-v3-50-for-b450#66054 https://forum.asrock.com/forum_posts.asp?TID=12097&PID=66044&title=no-turnonafterpowerconnect-in-v3-50-for-b450#66044 Author: Ray62

You are not the first with that problem:

Hmm, workaround with switch on by a key, if you have a PS/2 keyboard:

Hi. I just got a new B450 Pro4. I came with BIOS v3.20, but I updated to v3.50 to fix the stuck-at-boot-screen problem I had. That went fine, but there seems to be no way to make the board turn on when I reconnect power.

In 3.20, there is an option to turn this on in "South Bridge Configuration", but this seems to be disappeared. Now both South&North bridge configuration gets replaced by a single "chipset configuration" with far fewer options. There is an option to turn back on after power loss, but that is not what I'm looking for.

I don't have a proper case, so I use a switch on my power outlet as one, and set the motherboard to turn itself on after it started receiving power. This works with 3.20 as well as my old ASRock Z87 Extreme6 and many others, but there seems to be no way to set it in 3.50. Was it removed? If so, can I request it to be added back in the future version?]]> Sun, 04 Aug 2019 20:30:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=12097&PID=66041&title=no-turnonafterpowerconnect-in-v3-50-for-b450#66041
