Early-2011 13" Apple MacBook Pro Dead Logic Board Repair
In this video, I go over the process of repairing an Early-2011 13" Apple MacBook Pro that partially turns on, but the fan will not spin and the system won't boot. The issue ended up simply being a bad current sensing resistor on the PPBUS_S5_HS_COMPUTING_ISNS / PPBUS_G3H rails. Replacing this resistor completely fixed the board.
