Schematic diagram for the Apple logic board 820-00164, compressed into a 1.25 MB RAR; the Lx tag in the name is not explained. Apple MacBook boards are identified by the 820-xxxxx number on the PCB, so match it before working from these pages. The schematic shows power sequencing, rail names, SMC and charging circuitry and signal paths, letting a technician predict expected voltages and find the failing stage. Use it together with the boardview for the same board number to place parts physically.
