I'm changing t2 chips so something like u7000 or cd 3215 is too easy! there, no less, to exclude the u7000, I removed it from a fully working machine and checked in diode mode all the indicators around it were normal; the u7000 removed from this board works perfectly on the donor board. I turn...

I turned off f7000 and f7001 and my consumption is stable at 0.000A

I have a consumption of 20 V and 0.000A! Does PCH (U1100) affect this? Or do I need to figure out the power supply circuit first?

I forgot to mention that there were traces of liquid (oil) in the area of the u7650 chip

PM_SLP_S4_L=0v no pulse PM_DSW_PWRGD=3.4V PM_BATLOW_L=3.3V 3 PCH's RTC (DC) signals (page 12).I hope you meant these lines PCH_INTRUDER_L=2.83v PCH_SRTCRST_L=3.08v RTC_RESET_L=3.08v

Unfortunately, with this the BIOS does not turn on either, this is strange, maybe I’m wrong in thinking that the BIOS is to blame!

PPVIN_G3H_P3V3G3H=4.76V

I apologize for my inexperience, but I’ve been with you for three months and don’t have the knowledge that is obvious to you!

SMC_RST_IN=0V SMC_RST_BTN_L=0V SMC_RST_R_L=0V

MacBook won't turn on with this bios

and even after pressing the power button, the system starts to boot after 27 seconds, which is a very long time

yes the macbook works in safe mode

PP3V3_SUS=0V if you short SMC_ONOFF_L to ground, the voltage drops on PM_PWRBTN_L from 3.3V to 0.334V

C6990 =0.515 L6995=0.324

yes of course here are my basic measurements PPBUS_HS_CPU=12,64v PPBUS_HS_GPU=12,64v PPBUS_HS_OTH5V=12,64v PPBUS_HS_OTH3V3=12,64v PPBUS_S4_HS_TPAD=12,64v PP3V3_G3H=3.4v PP3V0_G3H=3.0v PPVCC_S0_CPU=0v PPVCCSA_S0_CPU=0v PPVCCGT_S0_CPU=0v PPVCCIO_S0_CPU=0v PP1V2_S3=0v PP1V2_S3_CPUDDR=0v...

I think the problem is in the BIOS! how do you think ? could you help me with a BIOS with a clean region for this board?

Now let's go back to this board and it won't start from either the internal or external drive

I'm sorry, I wrote this in the wrong topic for Mac A1708

Let's get back to the board problem! P_IN, =apparently you mean PPVIN_G3H=4.76V AUX_DET, =apparently you mean TBA_AUX_DET=1.26V SMC_RST_IN =0V VDDA/P, =apparently you mean TBA_VDDA=5.07V and TBA_VDDP=5.07V EN_VR1, =apparently you mean BANJO_ENVR1=0.031V SMC_RST*, =apparently you mean...

ok I have a diagram and boardview 820-00840 but as I understand it it’s 820-00840-1
