1V25_S2 no value and I have 260 ohms and it is not short-circuited
and I have the same value before changing U7700 and U8100
I tried but nothing works, it does not enter DFU mode
We replaced U8100 and U7700.
PP1V5_UPC0_CORE OK
PP3V3-UPC06_LDO OK
PPVBUS_USBC0 5V
USBC0_CC1 1.6V
RF403 I have 0.5V
It does exactly the same thing.
We connected it to the computer and it is not detected in DFU mode.
Afterwards, the computer stays at 5V and does not switch to 20V.
What is...
A2338 remains at 5V and 0.018A (The motherboard has not been damaged by water; it is in perfect condition.)
I checked UF500 and UF400; both are fine. We checked them on another motherboard, and they output 20V.
I flashed UF260, but nothing changed.
We even replaced U5200, but nothing changed...
I put the NANDs from my A1932 motherboard on my 2159 motherboard.
So the U8600 A1932 NANDs on the U8600 A2159 and the U8700 A1932 on the U8700 A2159.
When I restore it with Apple Configurator and my Mac mini, it works, but then I get a padlock on the Mac mini and no display on the MacBook...
Hello,
We have a MacBook A2159 820-01598.
When we put it into DFU mode and start a restore, the restore crashes.
We have all the voltages on the NANDs and we think that's where the problem lies.
1-Can we take the NANDs from the A1932 and put them on the A2159?
2-We are going to put the...
Hello,
I have a MacBook A2681 820-02536
The customer brought me the computer, which would not turn on. I found a short circuit on the C77F6 capacitor.
I removed it, then replaced the PMU U7700, and the computer started up normally, but the battery is not detected.
When I test the values of the...
I have a MacBook Pro (A2442) which has been exposed to water and is therefore oxidised.
The MacBook lights up with the battery but when I plug in the charger it doesn't charge but takes 19V 0.000A.
So it doesn't charge the battery.
When I work on the motherboard without the battery but I plug...
Hello,
I have a Macbook A1932 that works, but I have no internal and external image and the keyboard does not work and the capital letter light does not come on.
I have the 19v, but when I put it in dfu mode using a software (DFU Blaster Pro)
to restore it with apple configurator it gives me...
Hello, I have a computer that won't start due to oxidation, I changed the trackpad pad and the trackpad it started, but the client doesn't remember its code, we have to reset it.
When I wanted to reset it, I pressed the on/off button to put it in recovery mode. It doesn't come back and it starts...
i replaced the nands that i took from a working a2159 motherboard and soldered them on, i put it in dfu mode and restored and at the end of the restore i have a padlock on the mac for apple configurator that appears but i have no display on the a2179.
I had another A1707 with no problems (we'll call it N ), I did some cross-testing
My motherboard works on the new chassis (I have display )
N's motherboard works in the other chassis, but it took a while to display.
My motherboard has no problem, I just need an original A1707 screen.
For me, the...

exactly 0.10 milliamper
i have say up the voltage on big coils
i have :
5v L7670
3V L7690
12V L7030
0V L7400
0V L8410
0V L8100
0V L7210
0V L7220

Hello,
At first the MacBook stayed on 5v
I saw that the U3100 component with the thermal camera was heating up, so I replaced it,
now it goes up to 20v but I have no display
with the battery: at startup it rises to 0.80mA then stabilizes at 0.50mA
Without the battery: on start-up it rises...
