Hi! this is a Macbook pro A1278 MB: 820-3115-B. It came to me from another store with an attend to repair. Now im trying myself to repair this one.
It doesn't turn on and there is no green/orange light either.
Im using mac power cable by-3200.
those are the actual voltajes values and missing lines:
im stuck here with this one here. dont know where to look now. im thinking about SMC (i already change it, dont know if it is ok)
thanks for the help!
PPBUS_G3H = 12.26V
PPBUS_S5_HS_OTHER_ISNS = 12.26V
PP3V42_G3H = 3.47V
PPVRTC_G3H = 3.47v
SMC_BC_ACOK = 3.33V
PP1V2_S5_SMC_VDDC = 1.2V
SMC_ONOFF_L = 3.47V
SMC_RESET_L = 3.44V
SMC_BATLOW_L = 0V
SMC_ADAPTER_EN = 0V
PP3V3_S5 = 0V
PM_SYSRST_L = 0v
PM_RSMRST_L = 0V
PM_PCH_PWROK = 0V
M_RSMRST_L = 0V
PM_PWRBTN_L = 0V
SMC_PM_G2_EN = 0V
PD: i don't have oscilloscope to check the CLK32k.
