No trackpad and no keyboard
This one had endured a tropical rainforest, which fried the display, but was still working on external monitor. I think, if I remember correctly, even keyboard and trackpad worked then on external monitor. So I installed a new LCD, and it boots up fine, except now the keys and trackpad do not respond. All else is fine. Maybe just the cables? Also need to mention that C2837 was corroded and came off. It is part of DP_TBTSNK_ML, Thunderbolt circuit, if I understand correctly. Would that influence the trackpad and keys?
