I replace the SMC and the fan is spinning I have a green light but there's no imagine and there's no chime. When I press the Shift+Control+Option I get a green light and then an orange one that means the SMC is resting. Is it something to do with CPU Vcore?
PPVCORE_S0_CPU is 0.95V
I measure all SPI Bus Series Termination resistor i checked all the traces with multimeter I don't know what to do I can't find the problem.Is it SPI ROM the problem? Should I rewriting the SPI ROM? Should I check some place else?
the CPU Vcore is doing the same...I tested all the rails for a short to ground nothing... SPI lines are fine
TPSPI_SMC_CS_L looks bad and TPSPI_MLB_CS_L but they are test points
I noticed something else I did put back the original U6100 and I took u1900 from a donor board now the fan is...
Yes was water damage. There was corrosion around U6100 that was the place where the water traveled under the board and stopped at u6101 I did replace u6101.
It is quarter fan spin because it's just for one second.
resistance pins 17/18 it's 3.17 ohms and 27/28 28,18 ohms
2informaticos I don't...
I have this MacBook air 820-00165-02 the PP5V_S5 present
PP5V_S4RS3 getting voltage but is dropping
PP5V_S0 getting voltage but is dropping
PM_SLP_S5_L is getting voltage but its dropping
any ideas where to look
PPDCIN_G3H 16.49V instead of 20V
PPDCIN_G3H_ISOL 17V instead of 20V
PP3V42_G3H 3.41V when I took the measurements at l7095 the fan start to spin. i...
