Powerbook 3400c powerboard

My Powerbook 3400 i just bought does not want to stay on. I found out it is the powerboard under the trackpad that is bad and causing it to shutdown during startup. Is this capacitor related or something else? Thanks

Possibly - only two electrolytic caps on it, so probably worth seeing if a cause. Also one more on the logic board.

Good point i checked the solder and its fine it makes a small squealing noise during startup on the powerboard
