    Here are the voltages of the LDO's. LDO0_IN = 0.465 unstable LDO1_IN = 1,288 unstable LDO2_IN 0.010 LDO_CORE=0.249 unstable LDO0 = 0,00 LDO1=0.00 LDO2 = 0.043 LDO3 =0.010 LDO_RTC=0.00

    The LDO's are the AWAKE and the SLPS2R lines right?

    I jumped R7900 but still the same readind on my USB meter , its still stuck on 5.22 v 0.002 amp and 0.00 watts, Let me know what other suggestion that you might have.

    Great. I will run a Jumper then. Will keep you in the loop.

    Ok, I don't have a donor Board here of the same macbook , where can i get a 0 ohm resistor to replace that one ?

    I am sorry i am a bit confused, so R7900 Should read 0 ohm in order to be good ? My new question is I don't have an exact donor board here , Do you have any suggestions where else can i find another resistor with the same capacity ? (R7900)

    So you conclude that R7900 is burnt as values are not the same on both sides.

    Yes even 0V8 =0.000 for R7900 One side PP3V3_G3H_PMU_VINRTC_R = 0.493 and the other side PP3V3_G3H_RTC = 0.340 in diode mode to ground.

    Yes, I put the Blue stuff on a side , I checked the voltages of The small coils around U7800, The AWAKE Voltages PPVDDCPU_AWAKE = 0.589 PPVDDCPUSRAM_AWAKE =0.00 All the SLPS2R voltages = 0.000 Does that mean U7800 is dead?

    the 0.47 ampers , that's what i got on the small blue device, I do ave the USB-C meter and on that one i got 5.08 Volts 0.008 Ampers and 0.000 watts

    I have not done any DFU mode test yet , I did test the Board alone by removing it completely out . When I connect it to my DC POWER SUPPLY , its consuming 0.47 milliamps. Let me know if there s any other test to run please.

    Hello, Looking for some help here , This macbook came in dead , customer stated that it was charging and left connected overnight then the next day the computer was not coming on , I opened it and found U4910 and U4920 were both fried to ashes, When i ran a quick Diode mode only in that area I...
