Hello, No sign of life. I see big coil diode mode value is low... Could it be anohter chip than CPU shorted ? PPVBAT_G3H_CONN - Diode .817 PP5V_G3S - Diode .377 PVCCSA_S0_CPU Diode .012 PP3V3_S5 Diode .330 Big Coil L7410 .003 L7420 .003 L7211 .001 L7221 .001 L7231 .001 L7330 .001 LA340 .001...

Hi, Macbook air suden death. It was stuck at 5v -0,4 amp. I found L7800 completely burned. I removed it, now it's 5V -0,004 amp. Now I have diode mode .464 PIN1 and .224 PIN2 where L7800 was. Can I replace it and try to power or should I check something else ? Thanks Claude

Hi, Macbook get 5V and stay at 0.16 - 0.40 amp. I found a short on CF131 PIN1 near UF500. It's PP0V9_ATCRTMR1_VCCA. It's connected to CF143, CF130 and RF101 and RF100. I want to make sure my diag is correct. I have .019 on diode mode, so it really looks like a short. Compare to simialr cap...
