Multiple liquid damage points. Near R8711 ssd 1v8 power was especially bad. Replaced and tested nearly everything in that section.

Also found damage on cc805 and cc804 pins 1 pads were missing completely. Replaced and reattached with magnet wire. Nervous about that since it's CPU power related. I'm new to these boards so apologies if I missed important values.
