Macbook Air A1466 2015 no chime, no image (PP0V6_S0_DDRVTT)
Thx) the motherboard is clean! The only thing that I noticed strange is that with a 45W power supply the board starts up, and with 85W it detects but does not start, is this normal? PM_PCH_PWROK — 3,4 PM_PCH_SYS_PWROK— 3,4 CPU_VCCST_PWRGD - 1 PLT_RESET_L — 3,3- Moss
