Do you have a message on boot that says there is not enough AC power or just black screen?

Can you access BIOS with the 4810?
Totally black screen. No bios, no message nothing...

Sounds like a faulty CPU.

Take it out, check if any pins are bent.
Yeah, I did that a few times and all looks good... I don't know what else to check to be honest... I've contacted the seller. Let's see what they say.

Happy new year @Sniki , I trust all is well at your end? I now own a Thinkpad T470s and I'm wondering if we can work on a guide for it. I am currently running on 10.15.3 with some issues still left work on.

Is it possible to get VGA working on this machine?

@Sniki Hi, do you have any idea to unlock the cfg lock with thinkpad bios? I cannot use setup_var tools to solve the issue

I just got a 4k LG monitor and I'm having trouble getting the full 3840 X 2160 resolution. I'm using a thunderbolt-displayport cable to connect it. In the display options the scale only goes up to 2560 x 1440 for some reason (screenshot attached). I've tried using the displayport connection from the docking station but still have the same problem. I know my setup is capable of the full resolution since it works perfectly when I boot into linux. Is this some sort of limitation with the whatevergreen kext or something? If I can't get full resolution I might as well return the monitor and get something else.

Debug reporting files attached. I'm running Mojave 10.14.6 BTW.
