What are these components?

Hi,

I have this MacBook Pro that does not let me install an operating system, I have tried multiple versions of MacOS, Windows and Linux however all of these froze during installation and would not complete.

On the odd occasion I was able to get the progress bar for MacOS to 100% but it would not budge after that.

I have tried all the typical solutions to this problem (resetting SMC/Nvram, disabling the dedicated gpu, e.t.c.) however none of these methods proved effective.

On closer inspection of the logic board, I found that these 2 components (pictures) appear to have their connection to the logic board damaged. I would like to know what those components are and what they are responsible for in the device. Could they be the source of my issue?

Any help is greatly appreciated! : )

Thanks

@computerashes those are both 0.36µH 26A 1.05mOhm Inductors in a MPCG1040 package. They are critical components for your CPU Vcore regulator circuit.

@computerashes did you ever fix those inductors?

@oldturkey03 well a slightly more capable soldering iron arrived yesterday so I am planning on retouching the connections

@computerashes okay sounds like a plan

You likely have a simple problem! Let’s get a bit more info what is the amount of RAM you have installed and what drive are you using kind HDD or SSD AND its Make & Model.

I have 2GB of RAM installed in one slot as the other slot appears to be faulty as well as a 500GB Seagate HDD (I don't know where to find which model it is) The HDD has been pulled from another fully working Mac

@computerashes - 2GB is quite lean. I would put in a 4GB module. For the drive take a picture of the drive labels and post them here.

@danj Here is a picture of the drive label: https://cdn.discordapp.com/attachments/1...

I am hesitant to add a 4GB stick as I am running low on thermal paste to put the device back together and I do believe that it is a board level issue - I have a few MacBook's from the same era who run fine on 2GB of ram.

@computerashes From your pictures I would say that the components, whatever they are, appear to be intact. It looks to me like a couple of the solder joints have come apart; if it was mine I'd try touching them both up with a soldering iron to resecure the connection then see if it makes any difference.

@dadibrokeit That was my initial plan however I thought I'd ask what purpose they serve and if they are at all linked to the Kernel as it does occasionally Kernel panic.
