Chosen Solution
I pulled the FDC clip contacts 3 of them right off the board, this is not the logic board I see for sale and that repair shops think I’m talking about. There has to be another way of connecting the fans flexy cable to it’s required +- signal and so forth, could I just jumper it to the other fan? They want 1100$ for this, not a chance its not the board with the processors and so on its on a board you can see when the logic board is taken out. the computer was 3grand Canadian im not gonna believe that price when its not the main logic board, someone spoke of finding potential contacts with there multi meter and hooking the fan up, he stated it was doable because they use PWM. Any help would be amazing
@meticulous @arbaman take a look at the schematic. Looks like it only uses 2 of the 5 pins
@meticulous post another image but zoom out so I can see the orientation of the contacts etc. Getting old and can’t see very well ;-) Update (05/28/2019) @arbaman @danj here is the fan connector etc. What do you think
Technically what you have in mind could be done but it’s going to require precision and fine tools. I don’t have a schematic for that board and although picture is good, magnification is not enough to give a clear answer. Two pads could probably be recreated by lightly scratching the adjacent surface enamel and make a jumper with copper wire. I can’t really tell where the central one of the three lifted pads should go but a microscope should probably give an answer.
It is a bit hard to say for sure, given the picture is not clear enough, but I believe a microsoldering tech can scratch and find a nub of the trace. Then it would be possible to tin that nub, and jumper the fan cable to it directly, altogether skipping the connector. Heat should be used very conservatively to avoid damaging the keyboard. I would do it this way myself and charge less than the cost of replacing he keyboard (your second option) or your whole top case (your third option). To say for sure that this is feasible would require the device to be on my bench. So my advice to you is to find a reputed microsoldering tech near you, and let her/him have a look and quote you a price.
