lenovo x1 yoga fq20 Ripped bios chip pad on board

[wheats123]

While trying to desolder a bios chip from my lenovo x1 yoga fq20, I made a huge plunder and ripped the soldering pads off...Is there a way to replace the pads or did i just destroy my board? I provided a pic of the damage.

Yep it’s still possible to bring back it alive but we need the Bord ID Schematic a close up pic with a loop try and find one of them or the Schematic

what u need is microscope. even cheap to see the traces

u dont need a schematic. just scrape mask of remaining traces and solder pins to it with wire
