Trying to fix my MacBook Pro's keyboard and trackpad issues with not responding (more likely not being correctly powered, since the Caps and Num buttons don't light up).
I'm 95% sure the problem is in the power of the peripherals, supplied by the orange (left) ribbon, but my multimeter measures 5V in the ribbon tips and 4.99V in the board connectors (in this view are the rightmost (gnd) and 4th from the right (vcc) pins).
I feel absolutely clueless about this, I cannot get why sometimes it does work with pressure applied, and other times it doesn't. Sigh.
