    Macbook Pro A1990 820-01041 server not connecting

    Hi

    I received this Macbook Pro A1990 about a week ago with a question mark folder blinking on the screen.
    I tried to restore the OS using CMR+R but when selecting install fresh operating system (the option was for High Sierra) I am getting every time "unable to connect to server".
    I also tried to restore from DFU. The message from there was a bit different. Something like "unable to revert partition to a bootable one".
    To be honest I am out of ideas here.
    Do I have an actual hardware issue?
    When I am deleting and formating the internal SSD through Disk Utility it all goes well.
    Did anybody had similar issues and found a solution to it?

          Suggest to use a wired connection with a driverless Ethernet dongle (ie. Asix Ethernet controller). Then test again. The default os driver packages support Asix by default.

              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 — No Display With Battery Connected
              by mavaro
              Hi, I have a problem with MACBOOK A1990 - The laptop starts with no image when the battery is connected, but without the battery it starts with an image - however, when using only the power supply, when logging into the system it turns off and resets again.

              Battery replaced with another unit → same problem.

              ISL9239 replaced → no change.

              SMBUS_BATT_SCL / SDA measure ~20-50kΩ to GND with battery disconnected (normal).

              Any ideas or advice would be a huge help!
              Thanks in advance for your time.​
