    820-2530 - Green Light, No Fan Spin

    As would be expected, I don't have that cap, so I'll put together an order and probably get some of the 100K 1/16W resistors. I have 402 package 1/10W, but I'm not sure if they're metal film or ceramic. While I'm putting together the order are there other likely parts that I might need to...

    820-2530 - Green Light, No Fan Spin

    PM_BATLOW_L is 3.316V. SMC_ADAPTER_EN is 3.401V. SM_INTRUDER_L is 3.401V. U7840: Pin 1 RSMRST_PWRGD is 0.151V. Pin 2 is GND. Pin 3 P1V05_S5_PGOOD is 3.392V. Pin 4 CT is 0.429V to 0.430V. Pin 5 PP3V3_S5 is 3.320V. Pin 6 is 3.419V. I'm confused as to where to go next. It seems like I'm missing...

    820-2530 - Green Light, No Fan Spin

    PM_PWRBTN_L measured from the test point near C4902 is 0.016V. Is that the only place to measure it? PM_RSMRST_L measured on R2151 is 0.001V. RSMRST_PWRGD at R7840 is 0.220V. Triggered SMC_ONOFF_L across R5016, the power-on pads, and the voltage of PM_PWRBTN_L remained at 0.016V, with no...

    Hello, U7200: Pin 3 (5VS3_3V3S5_VREF), as measured using both/either of C7271 or the test point near there, is 2.000V. Pin 8 (5V3V3S5_REG3), as measured using C7270 and the nearby test point, is 3.321V. Pin 13 (5V3V3_REG_EN), as measured using R7273 or the nearby test point,is 3.388V. Pin 16...

    820-2530 - Green Light, No Fan Spin

    Hello, Thank you for the reply and it's good to be here (and not just lurking). Specific voltage of PPBUS_G3H as measured at pin 2 of F7000 is 12.59V and 12.60V at pin 1 of C7272 (near U7200) on the board. I measured resistance to ground using pin 2 of U5000 at received 2.566K; notably not...

    820-2530 - Green Light, No Fan Spin

    Hello, I'm troubleshooting an 820-2530 that consistently shows green light on charger but does not spin the fan. I'm not quite sure what to test next and I'm hoping for some help. I have 16.98v on pin 2 of U7000 and PPBUS_G3H appears to be present, though that may be obvious because of the...
