My logic board is different [ I've also experienced dead keyboard ]. https://mega.co.nz/#!dFcQCKoa!cWsDGQ90Qw... On my board, these pins was covered with protective insulant, so I have to scratch it. But it didn't start. I have to reset also SMC ( system managment console ) Resetting the System Management Controller (SMC) If bottom case is removed,you can alternately reset SMC by disconnecting both power adapter and main battery, and holding down power button for 5 seconds.
