Remove the CMOS battery before power on and hold ESC during startup. Be aware Sure Start can revert this change.

Hi, Try this BIOS file and give feedback

HP Pro Mini 400 G9 BIOS and System Firmware (U23) Version: 02.21.00 Rev.A

Hi. I flashed your 02.21.00 dump on my HP Pro Mini 400 G9.
Nothing changed. I flashed the EC from message 61. Same thing.
With the i5-12500T processor that was in the PC, the board reports no memory, but at 30 watts it freezes and then goes silent (it doesn't even get to USB initialization). Now I'm assuming my processor (i5-12500T) is partially dead and that's the culprit.

I tested it with an i3-12300T. I have two of them. With both, it returns error 3.6 due to the firmware being tied to the corporate ME. That's what I think, but maybe I'm wrong. Please advise.

I also tried putting an i5 14500 processor in there - error 3.4.

Perhaps you have a BIOS with a clean Consumer ME for regular processors, or could you tell me what's best to do here since I don't have a known-good i5-12500T to test and I have nothing to test it with.

Hi again, The HP Pro Mini 400 G9 is a business/enterprise product line, not a consumer model

3.4 The system board displays a power failure (crowbar).*
3.6 The processor does not support an enabled feature.

I suggest moving to the parent Troubleshooting Section You might get the hardware-related help you need there
