    Help with Macbook Pro 15 Retina mid 2012 stuck in loading screen with Apple log

    Good day everyone,
    Thanks for all the help and support from this community. I really appreciate them.
    I have a MacBook pro Retina 15inch mid 2012 that turns on and get stuck in the loading screen then reboot. There is no sign of liquid damage. The history of this MacBook pro is I got it dirt cheap at a garage sale. so I have no idea about the story behind it.
    I was able to extract the Bios dump and it attached to this post to see if someone knowledgeable could help me if the bios is somehow corrupted.

    SN = C02J5DCRDKQ1.

    Thanks again.

                              Thanks peste. Now it chimes and boot but it still get stuck at the loading screen and then reboots. maybe I have a different problem other than the Bios.

                              I really appreciate your help. I will report back if anything changes.

                                  All thanks go to Peste for helping with the Bios bin file. The MacBook is running now after I change the hard drive. Thanks again Peste!!

                                      Will I have a bricked logic board after reflow of the GPU v-core U8900 chip on my Mid-2012 15" Retina Macbook pro?
                                      by korben_dallas
                                      Hi everyone! I'm trying to fix my black screen / failed U8900 GPU v-core on my Mid-2012 Macbook Pro 15" Retinaby doing a rework/reflow of the chip (once I determine that's the real issue; but it likely is).

                                      I've been disabling the GPU in NVRAM for a few years... but it's just time for a better solution.

                                      I'm new to soldering but the only feasible way to fix this issue is to do something myself.

                                      MY QUESTION:
                                      I've been seeing some people (on this forum mostly) run into issues with the logic board needing a serial number or it being deactivated (?)...

                                      Hi,

                                      I have a MacBook Pro 13 inch A2238 M2 and it was stuck 5V with 0 amps. I measured some important lines and I found a short on PP3V8_AON_MPMU_ISNS_VIN, I tried injecting 1v and I saw heat coming from the mPMU so I removed the pmu thinking that was the problem. I don't know why I didn't check the other side of the border but there it was, a shorted cap. I replaced the cap and the short was gone, so I reballed the PMU and put it on again but voltage was still stuck at 5V and the current was fluctuating between 0 and 0.45 amps. I checked under the thermal camera and I saw the mPM...

                                      Hello, I am looking for any and all files related to the mainboard for 820-2565-A (13" Macbook Pro A1278 mid 2012) schematics/board view.

                                      I looked through forum search results and google and was unable to find a board view file, I found a pdf of all the schematics but I don't know where the parts physically are on the board as this is my first macbook board level repair attempt.

                                      The macbook charger has a green light, the battery has been replaced and OS reports Normal status but Not charging. After cleaning a corroded capacitor it crumbled off the board. There...

                                      Macbook Pro A1706 820-00923-05 Stuck At 5V 0.03A
                                      by Steven Pieter
                                      hello everyone, let me ask, I have a macbook which is stuck at 5v and 0.03 A when tested with a usb tester. Previously I wanted to replace the screen on the device, but by accident I forgot to unplug the battery. This caused the MacBook to get stuck at 5v, previously I had replaced the CD3215 (U3100) IC because it was warm. After I replaced it the problem was still not resolved. Please guide. Thank you

                                      Macbook Pro A1990 - 820-01041 Stuck at 5V / 0.02A

                                      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...
