Laptop won't turn on after installing the new hinges

So I just installed the new tighter hinges on my 12th gen Intel framework 13. The process went smoothly, but now my laptop won’t turn on!!

No weird lights, no nothing. When plugging the cable, I get the regular charging orange light.

EDIT: at some point I see alternating blinking green and red lights. Not all the time…

If the cover is off, I do see the blinking red lights.

I reset the screen cable and made sure the cables are routed correctly. I unplugged and replugged the battery. I removed the RTC battery…

I’m lost and desperate here!

Any clues?

Try checking the what step the computer is failing at.

Here are the indicators for the boot light codes that you saw. This is for the 11th gen Framework, but I’m pretty sure it works for the 12th gen one as well as they have not posted blink codes for the rest of them.

There are no lights at all when I turn it on. Power button is off and side leds are off.

If I keep it plugged, I randomly see the green lights blinking.

Also, the button is working, because with the cover off, when I press the power button, I get the red blinking lights.

The green lights should be the light code you are looking for.
