    MacBook A1990 820-01827

    Please help me identify the microcircuit. There is no schematic for this board and I cannot understand what it is.

        i9 32GB Ram 1TB

        Hi, I found short on one of 6 black nand (total 1TB).
        i removed all 6 nand ( voltages all ok) and now i want to program with JC P15 but for A1990 2019 there is only 512GB configuration.
        I try A2141 1TB configurazion with TSB4228 but the position on pcb is different ( U9300 and U9400 is no stuff on A1990 but present on A2141 and U8800 and U8900 is no stuff on A2141 but present on A1990 )
        macbook with A2141 configuration run on recovery but don't complete it.​

        MacBook Pro 2018 - A1990 Dead - not charging - only 5V
        by robka
        Hi,

        my MacBook Pro 15" 2018 Touch Bar (A1990) doesn't charge anymore. Board# 820-01041-A

        I'm not experienced in diagnostics, but I want to try to solve the problem with your help, because every local shop charges around 600€ (650 usd). Which is the value of the whole Macbook.

        The Macbook was charging when suddenly the "charging sound" appeared every other second for around 4-5 times.
        After that the Macbook was dead. It isn't charging anymore.

        The USB-C Port where the charger was plugged is burned. Also The Cable and the...

        Macbook Pro A1990 - 820-01041 Stuck at 5V / 0.02A
        by DATATECH85
        Hello,
        I am currently working on a Macbook Pro A1990 (motherboard 820-01041) which is not charging.
        The Macbook consumes 5V and 0.019A at USB-C. There seems to be a partial short-circuit on the PPBUS_G3H rail as I have 0V on this rail.

        I've physically separated (by removing F7000 and F7001) PPBUS_G3H and the ISL9240 charging chip to see which side the short is coming from. Removing these fuses gives me 12.6V at the output of the ISL chip (PPVBAT_G3H_CHGR_REG).
        However, I can't work out exactly why I don't have the PPBUS_G3H rail.

        Here are the values...

        A1990 MacBook no power help
        by Cameron Kajohn
        I have a a1990 2018 15 inch MacBook Pro that will not power on.
        I have replaced the pch bga chip because it was heating up under my thermal camera.
        I have replaced the battery, and replaced the small ic between the gpu and cpu as it had a direct short to ground.

        the MacBook now pulls 20v 2.4amps the trackpad clicks but it does not ever attempt to power on not even fan spin. After PCH replacement I was able to get it in dfu mode 1 time and restore bridge OS, but now the MacBook will no longer go into DFU mode.

        I have also noticed L7030 gets extremely hot yet...

        MacBook A1990 vertical stripes on external screen
        by ahoonid
        Hey everyone,

        I bought a MacBook A1990 with no screen. I bought it knowing the motherboard was defective but wasn't sure what the problem was until I received it. It actually turns on but as you see from the attachment, it has vertical stripes, on an external screen!!

        The board is neat. Not opened before for sure. Just a little dust, nothing more.

        Recovery using wifi can be opened, as can also be seen in the photo but it doesn't go all the way through after connecting it to a wifi. It downloads the initial Recovery files but never completes the rest of the...
