Lenovo Thinkpad T14 Gen 1 NM-C801

Hi

I got my fist laptop that probably has a MOBO problem finally, charger light works, it "powers on" off the battery, power button lights up, but I get no display even on HDMI, I found a bad connector, but the schematics don't explain it's function. It should be a lid board connector, but I'm not sure if that could be a reason for it to not power on. Could it be it? Or should I check power rails even though the laptop looks like it tries to power on? Where would you recommend me to start checking?

I attached the connector picture to make sure I got it right.

Thank you for any advice.
