In an attempt to solve some of the issues I have with FW13 AMD, I decided to update the BIOS. Found the files, prepared the fat32 USB disk, copy files and boot. Until this point all went as described in the documentation. However at the point when I suppose to be asked to swap USBC power to another port, this never happened and computer start to restarting without any prompt or my input. Then after the reset it was showing blank screen for several minutes when I’ve decide to hard power down. The result was, it spin a fan for a few seconds and turn off. This repeated every time, after I pressed the power button.
To resolve this issue I tried to disconnect the main battery, which seems to work. However, I still encounter the runtime issues I’ve described in another topic. So, after another failed attempt to install a fresh new distro I took a look into a BIOS setup page a set the GPU memory to “Gaming” mode ( I have 64G or ram). After saving and reset I am experiencing the same issue and computer turn off few seconds after I turn it on. So again I’m going to disconnec the battery a start over.
It is very frustrating issue and help is much appreciated!

If you have a laptop with a battery, I don’t think that’s expected; that’s for when you’re running the motherboard standalone (or in mini-desktop-shell) without a battery.
If the screen is blank after you turn it on, after some maintenance like this, you should expect a couple of minutes for “memory training”. Let it keep trying for at least 5 minutes (some desktop amd ryzen systems with lots of memory have taken even longer, 10+ minutes!)
I remember I’ve wait for quite a long time before forcing power off. However, why does it keep turning off after I set video memory in the BIOS and save&restart? In such case, I need to reconnect the battery to make it work. This is very suspicious behavior.
Yes, I’ve waited 5+ minutes for sure.
However, I have a new finding. I’m using Kingston 2x32GB modules KF556S40IBK2, since the beginning, and they worked fine - for sure I’ve need to wait quite a significant time after first power off due to timing calibration (as many of you stated) - but they worked! But with this issues after (and during) the BIOS update I decided to swap them with another pair of 2x16BG modules (don’t remember the brand, but they were taken out of a brand new Lenovo and I have them as a spare part). After switching dram modules I am again capable of installing new system and boot with no issues.
I wouldn’t say it is a solution for me, as those 2x32G Kingston DDRAM worked for me at least for a year, or before I’ve update the BIOS. So the question remains the same.
Yes, I did run memtest on those 64G DDRAM, it runs for about 2 hrs and didnt show any errors (I know I should have to run it for a bit longer to be sure, but they worked for 1y).
