Often we receive Macbooks failing due to overheating; this was one of those cases. However, what we were about to witness was one of those rare cases where almost every component on this Macbook failed.
Even after so many failed components and quite a bill, the customer still wanted to have it repaired, as he knew that almost 10 years in operation on probably one of the harshest Australian places., this Macbook did not skip a beat.
Check out this insightful article of how harsh it can get out there – http://2livethedream.com/index.php/archives/3057?lang=en. Now imagine these laptop stuffed with dust and fluff, trying to cool themselves down from > 90*C.
It looked a lot like a graphic card failure, as these Macbooks come with a dedicated graphics card. It is very easy to overheat the graphic card. Which in most cases allows the system to turn on and in some cases chime. However, the screen may either show some kind of distortion or no picture at all. We have covered it in our Macbook Graphics Repairs section multiple times, as well as in our iMac Graphics Repair section. It is the same issue happening across all computers and brands.
We could not run many tests as the system was unresponsive, also unlike most of the repair shops around we do not diagnose all components first, then do repairs. We do it backwards, by providing the customer with an option after each step to either continue to repair or cancel the repair. This way, we let the customer decide when to pull out and burry the laptop and when it is still cost-effective to repair it. Check out our simple customer service infographic here.
Macbook Pro Retina turns on with black screen Repair Process
By now most likely you wonder how we repair this without actually testing every bit of hardware, we use the elimination process as most of the time we need all components to interact with each other so we can test them.
That said, first, we started with the GPU issue. We know itis a graphics problem, also it was clear it was overheating heavily, based on the dust inside. Which by the way was already cleaned when the customer took it apart before he rushed to us.
After lifting the heatsink, we could see how the thermal compound has seized and was not transmitting heat correctly to the radiators. Hence causing heat congestion on top of the chips. Check our great article of heat dispense on Macbook Retina if not serviced regularly.
After gentle cleaning and preparation, we placed the board into our reflow machine and let it do its magic.
We have mastered this, as it was and kept to be a common issue of failing graphic chips over the past 10 years.
After the reflow macbook turned on and start being responsive, now we could run some tests to ensure repair stability and catch if there were any other failed parts within.
We spun up our testing system and test suite and started testing and poking around. This was when we discovered that the SSD has failed, causing loss of customers data. As well as battery not reporting good health. Those required us to communicate it back to the customer and amend the initial quote we gave.
Most likely, you wonder – “Why you have not tested the battery and SSD initially?”
Well, this being Macbook Pro Retina Mid 2012, SSD connector and SSD onboard is a type of SSD which was produced only for 2012 Macbook Retina and some 2012 Macbook Air. Hence we do not have a testing system nor a compatible SSD adapter to test it correctly. As mentioned above, we do repairs differently here.

We have sophisticated equipment in our workshop with high accuracy microscope, ultrasonic cleaning bath, reflow machine and tools for micro soldering to achieve high-quality logic board repairs. With hundreds of components in stock, we can quickly locate and replace faulty chips, resistors, and capacitors in Macbooks.
Battery and SSD replacement pretty much is a norm here, so we quickly replaced them.
While we were assembling the Macbook, we have noticed that the Macbook hinges became loose. We could not leave them like this, and it would have damaged the screen. Knowing this model, screen replacement by its own would have cost more than all repairs done so far combined.
We took apart the hinge assembly and tightened the loose screws, while we were there we also applied some oil on the hinges to go for another couple of years with no trouble.
You can see how after oiling and tightening up the hinges, the screen assembly is much stable.
After successfully repairing its logic board, this Macbook is turning on now and working as expected. It is unbelievable how overseen overheating can bring this great machine to its knees. We salute the owner for deciding to have it repaired and not falling on the trap of buying these new low-quality Macbooks, which often come with a lifespan of no more than 2 years.
