I have this card 820-00850 that has the following values 5v 0.060 ppbus 12.26 3v3g3h 2.50

Hi, I have this board on which the USB ports relating to JF601 and JF600 do not work, or rather it works as regards charging, therefore input voltage, but it does not work for the output voltage, this measured with a USB meter in reverse to see if the ports supply voltage, while JG600 works...

p3v3g3h is stable but I saw that p5vg3s is very low but it does not have any low insulation I tried to replace U7600 for a moment the current rose and then returned to the initial situation measuring on r7609 I note that it tries to rise up to the nominal value and then turns off I do not think...

They are both stable obviously PPBUS_G3H and 12.30v

Hi I have this board that has 20v and current that restarts continuously 0.060 0.010 A I performed the swap of the soc T2 and the ssd nand from the donor board, the board enters dfu mode but the process blocks without returning any error I have no voltage on PP2V5_SSD or on L9030 L9021 or L9020...

Is it possible to use the PMU of an A2485?

I replaced the board where the keyboard is connected but nothing even if the voltages are present

a2681 with liquid damage on LT400 and UC850 and JT400, both touchpad and keyboard did not work, I fixed UC850 and everything started working again but suddenly the keyboard stopped working, while the touchpad and feedback work perfectly, I tried replacing UT3A0 and it started working again, then...

The version is the 1gb of ram supports the 500gb thing however goes on more than 20 seconds I did not encounter the same behaviour on another card I wanted to focus on ssd_pmu_reset L

Hi, I have this 820-01700 board, which I replaced with a donor T2. When I power it, the board is in DFU mode. Soc_dfu_statu is 1.8V. I try to restore it with Apple Configurator, but it gives me this error: "Unexpected device state 'DFU' expected 'RestoreOS'" Error 4014. I checked all the AWAKE...

In my case I solved it with a new battery, but the defect, I'm sure concerns the mosfets of the CPU, it seems the same defect of an A1398.

The MacBook is detected in target disk mode, I assume that the ssd must be good otherwise they wouldn't even show it to me, the only thing is that I can't do the installation in recovery because it crashes and restarts, the recovery in dfu mode stops without showing errors, honestly I don't know...

In target mode it is not detected I don't think there is an operating system installed

I tried to restore the dfu, it completes the operation without displaying errors but entering the recovery and trying to install the system it restarts and returns to the question mark

I have this MacBook that has a question mark at startup as if there was no operating system I enter the recovery but if I start the installation freezes and restarts if I try to enter the disk utility it crashes and restarts at the question mark, where should I start?
