We are missing power on 3V8_AON and diode mode to ground is 346ohm.

P3V8AON_EN_R is now restored and it is showing 4.49V. Is it correct voltage? Can you tell us what to check next?

R5710 is disconnected from the board, is it possible to make a direct connection? Would we be able to replace it with a similar element or would it have to be the exact match?

We are missing P3V8AON_EN_R and PPBUS_AON IS 12.33V.

Hey guys, We have a A2485 Mac book that uses 5.17v and 0a, we measured some voltages on the board and got this result. U5500 -> U5501 .2 UF400 -> RX421 9 UG400 -> RG012 3.3-3.6 LF000 -> 8.8 LF100 -> 8.8 CF800 -> 0 CR805 -> 0 CR853 -> 0 What could be the problem and what should we do next?

Here are some of the voltages we checked on the board. P3V3G3H_VSW/L7660 -> 3.36V PPV5_GS3/L7600 -> 5.13V PP1V8_SSD1/L9030 -> 1.79V PP0V9_SSD1/L9020 -> .9V PP2V5_SW2_TPS62180_SS/L9081 ->.022V P0V9SLPDDR_SW1/L7817 -> .899V P1V1SLPS2R_SW0/L7814 -> 1.1V PVDDIOMEMGPU_PHASE/LA870 -> 0V...

We checked the ports and all of them have the same behavior, we switched the board to another donor A2141 MacBook and the ports are using 20.6v and .14a across all ports and is not charging the battery.

Hey guys, We have a MacBook Pro model A2141 that had coffee spilled on it and did not boot up, it uses 20v and 0.12a. We inspected the board and found some corrosion and cleaned the board. Would you guys have an idea of what the problem is and how to approach it? I have attached a few photos...

The laptop says now it has "Failed to create activation request." What could be the issue and how to approach it or get around it?

You guys think it is a software issue or the display physically damaged? We don't have the schematics for this MacBook, could you point out where the display connection/connector is located? I have attached a photo for you guys to take a look. Also if you guys know where to buy these...

The laptop now comes to Activate Mac screen. Why is that?

When USB Flash drive is light is connected, it shows blinking light and usb ports works.

We were able to enter DFU mode and will try to revive the the MacBook, if that does not work what would be the next step?

I disconnected the battery, 20V and 0.47amps, there is a chime and black screen. Please advise what might be the issue. Thanks

Hey guys, We have a A2780 MacBook pro, when we connected a charger to it and it uses 20.4V and 4.28-4.44A but does not power on or react in any way not even a chime. Any advice on what could be the problem and how we should approach this issue? Regards, Zeydulla.

Hi guys, I have Apple MacBook Air A2337. The MacBook turns on normal. You can hear the chime. Then it shows exclamation mark on the screen and writes down below support.apple.com/mac/restore. Does it mean that SSD is dead? I attached photo. Please advise, Thank you

What is the most easy way to detect it? I have a working board, thermal camera, I can do voltage injection. Please advise best option? Should I do diode to ground on all test points and compare where we have voltage drop?

Why PP3V3_AON this line is comes and goes back?
