[Request] HP 22-c0063w "Unsupported adapter" error bypass

Hi everyone!

I have an HP 22-c0063w All In One computer with a broken screen here. When I power it on, the LED blinks to show an error code (and it would loudly and annoyingly beep had I not removed the speakers) and after repeating the code five times it briefly shows information about the system and the message
“ERROR: Unsupported adapter installed.
PC will automatically power down in a few seconds.”
If I don’t quickly hit F1, the computer then shuts off again.

I bought two genuine HP adapters; both with the right specifications and one that is supposedly the original power adapter for this machine but I am still getting the error. I suspect that it has to do with the broken screen. But if I access the boot menu, I can boot into an operating system and use it just fine so the computer seems to work.

I unsuccessfully messed around with it for the last few days and finally decided to ask for help here. I dumped the UEFI and tried to find something using UEFITool and by looking through modules using IDA to either find a way to ignore POST errors or to disable the message but I can’t seem to find anything helpful (and I have not even been able to find the error message in the dump).

Here is the original image from the manufacturer https://drive.google.com/file/d/1oWFu3EDr5eB7Kp9AK6cg0Cj8Ils6O0pK/view?usp=sharing

Do you have any tips/advice on how I should proceed? I am pretty new to this so please let me know if I missed anything obvious.

Anyone? I’d really like to get this to work to be able to use it as a home server.

I have an HP All in One. It has died twice, giving me the 3 long beeps and 4 short beeps. Once was when I installed a new external hard drive. The other time was installing a Windows upgrade (today). The solution that works for me, as described on other sites, was to unplug everything, including the power cable, for a minute (not 10 seconds), then reattach the power cable only. Started fine then both times. Then I could reattach everything else. Hope this helps.
