    MBP15.2012 820-3330 not finishing os boot

    I have this nice 2012 MacBook Pro from a friend here since a while and I never fixed it. Deactivated dGPU is not an option for him as he relies on an external display.

    It either hangs on late boot status bar or reboots (panics) from there. No artifacts, no lines....

    If I run it on integrated graphics no problem.

    I did not hear from failing 2012 nvidias nor do I know read about any common failure on theese machines.

    I think I ran asd efi without results.

    Would you replace the gpu or is there any other thing I should check ?

          Nintendo Switch Oled HEG-001: Second-Stage Boot Failure
          by privato89
          Hello everyone,

          I'm facing an issue with a HEG-001 motherboard that is unable to complete the Second-Stage Boot. I'd like to start directly with my conclusion, which is the decision to replace the MAX77621AEWI chip, and understand if it could be a correct evaluation.

          Before I dive into the process that led me to this decision, I want to mention that I have a fully equipped lab where I can perform any kind of tests.

          Let's begin:

          Following some guides online, I tried to understand how the Boot phase of the Nintendo Switch works, and what are the...

          Xiaomi router freezes at boot after re-capping
          by hinisa
          I'm using Xiaomi Router 4A gigabit edition as wireless repeater. It worked fine for 2 years or so, but last week, wireless started to disappear.

          When I unplug/replug the power, it was working fine for a day/half a day or so until it freezes again.

          After testing with different power supply adapters and concluding it wasn't the issue I finally opened the case and this was the situation:



          Anyway I proceed to clean up the mess and replace all caps but unfortunately it made the situation worse. Now router can't even boot, either it freezes during...

          MacBook Pro 2012 A1398 : Battery BMS circuit repair OR can it boot WITHOUT a battery ?
          by Ancient1
          Hi
          I received such Laptop as junk. Opening it I saw a lot of whitish water residue , but no corrosion really ( few coils have small brown rust marks, no green copper ).
          I cleaned all thoroughly and interestingly , its the Battery BMS board that has the real corrosion spots.. under the protective clear Goo !!

          I want to try and power up the laptop

          Battery is swollen. But I don't want to buy a new battery right now , of course .

          I started work on the BMS by zooming in on green spots . 2 VIAs are filled with rusted copper goo - who knows...

          Samsung un82ru88000f - Boot loop sort of but can correct with taping of LVDS ribbon
          by NolesFan
          Hello all... TV started boot looping. Opened the back panel and tried to isolate the problem. Just PSB no boot loop. PSB and MB no boot loop. Plug in the LVDS from panel to MB and boot looping starts up. It doesnt matter of order that I plug the LVDS ribbons back in, only 1 and no boot loop but as soon as 2nd one plugs in boot looping. I then noticed a flicker on the screen when I was closing the clip on the harness to the LVDS. Shut the lights off so I can see better, and I noticed as i slowly close it, I will get a picture, but as soon as it clips in, I lose picture and booting happens. So I...
