I am trying to find this part on the logic board. See pictures below. It might be CR812, not sure. Any help would be appreciated. And where could I find the part?

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 (?)... -
Good day all,
I got a 2007 MacBook from a friend. The fan was not working so it was overheating.
Once the fan was swapped, I installed an OS and it worked fine.
The board had quite a few corroded spots so I removed it, touched those spots with a soldering iron, washed the board in PCB cleaning fluid (I've done that many times), rinsed it with distilled water, dried it etc.
Unfortunately it doesn't work anymore. It does turn on, fan spins, power LED turns on. But no picture.
If I see that right, I have missed VCORE on L7100 (page 59).... -
Hi everyone,
I’m trying to remove a component from a 2021 MacBook logic board, but I’m having trouble.
https://www.electronicsdatasheets.co...s/tlv70733pdqn
I’m using hot air at 480 °C with full airflow and good flux, but the solder paste is not melting.
I know there’s a lot of thermal dissipation from the board, and I suspect the copper planes are absorbing most of the heat.
Do you have any tips for this kind of board? Would a preheater help?
Thanks in advance!

Hi all!
This is my first post and also one of my first "deep dives" into electronic repair. I'm used to doing basic tasks with computers, like SSD/CPU replacement, thermal past re-application, etc. So here's the story...
I have a MacBook Air M1 that I bought to repair (I know, I'm weird; though I'm a CompSci major and want to learn more
, and it will not display anything on the internal display. I have verified that there's no backlight, as I booted the laptop and shined a flashlight on it and there's no display; it does completely boot up, and shows fine on an external...

Hi
While messing around with my MacBook Pro, I stupidly pinged off a very small surface mounted component that I’m now trying to identify.
resistance tests show a rising resistance value, indicating a capacitor.
The laptop boots up and runs, however I'm choosing not to use it until I get it fixed.
i can’t see any markings on the capacitor at 10x magnification using a professional jewler's loop.
It seems like there's some damage to the capacitor - one side doesn't have "shiny bits" - can you tell I don't do this for a living!...
