Hi guys, so I have this macbook here and it have 3 problems. History not available, no water damage. 1) Touch bar not working, changed with known functional touch bar 2) Critical software update 3) Graphic errors on display and external display, no errors when in safe mode According to the...

Thanks for replay. There is no really history, over night this error appeared. Nothing special, no water, no drop. I changed the board 1:1 in other shell so battery, display touch pad and all other things were different. Today I have disconnected the display and conected to external monitor...

So I have here this macbook pro 15" A1990 which produces this error codes in the diagnose mode. The fans are spinning high and the macbook is very slow. What I read about this error, that changing the touch pad will solve this. So I put this mainboard in an second functional macbook and the...

I‘m searching for an ipad air 2 board file, cannot find it. Only found the normal pdf file

Do you have an idea where can I buy all schematics in a package for all iPhone, iPad and MacBook? Some weeks ago I found a site where this was possible but cannot find it now.

Today reflowed the half board around the CPU area and it seems to work actually!

This is no water damage. From one day to other doesn‘t power on

Should I use flux or without flux?

Hi, I have exact same board and exact same measurments like hgoncalves. With battery and usb-c plug it drains about 0,4A and 15V. Board is getting hot in the cpu area. My question is now (nothing to loose) what does ist mean reflow the entire board? Really the entire board or only the cpu area?

Yes. After cleaning the J6100 I connected the AC Adapter and the light was amber on the Magsafe. After that I put back the other parts checked the voltages and reassembled the macbook. Thank you again!

omg i cannot believe, I cleaned up the connector J6100 and now we have this voltages: PPBUS_G3H = 8,2v PP3V3_S5 = 3,3v PP3V3_SUS = 3,3v PP3V42_G3H = 3,42v SMC_PM_G2_EN = 3,42v SMC_ADAPTER_EN = 3,42v PM_BATLOW_L = 3,3v SMC_RESET_L = 3,38v I reassembled the macbook and voila this thing works...

Removed R7100 now SMC_RESET_L = 0,039v on R7100 Pin 1

U5110 removed still 0,469v on SMC_RESET_L Checked R5100 = 100kohm

SMC_RESET_L = 0,468v on R7100 Pin 1 Is this enough for present or too low?

I got this on C5126 Pin 1 but this is PP3V3_S5_AVREF_SMC PP3V3_S5 = 0,00v on C8130 Pin 1 so this line is not present After plug in charger 3V3_S5 raises slowly from 0,00volts to 14,7miliVolts in about 2 minutes, checked with oscilloscope PP3V42_G3H = 3,42v is present on R7095 Pin 1 PPBUS_G3H...

Just double checked there is no voltage on both pins on L7560

Ok I made a measurment fault. In OpenBoardview I had to tick the option "whole" because if search PP3V3_S5 it shows me all the other lines on the board with all prefixes even if I click on the PP3V3_S5, sorry my fault. So the 3V3_S5 is not present Edit: The short to ground on C8020 Pin 1 is...

The 3V3_SUS is produced from U8020 but on the U8020 PP3V3_S5 is 0,00v. How can it be that the same line on the one side of the board is present and on the other not present?

PPBUS_G3H = 8,2v PP3V3_S5 = 3,3v PP3V3_SUS = 0,00v

Now I understand what you mean 😊 my charger is 45W PP3V42_G3H is present now. Measured on L7095 Pin 2
