With the Sunmall cables I bought, I have fixed 3 MacBook Pros. I don't know that part number, but I did get three of them fixed. Perhaps it was just a coincidence, but I just replaced the flat cable and the Macs are working now.
The answer is not clear to me. Upon arrival, it had two of them It takes 3 days for our NJ address to receive the package.
Why the warranty is not mentioned makes no sense to me. This replacement part works perfectly and has been doing so for several months now.

My first reaction, as someone who didn't know much about it, was fright! I decided to order this to see if it was the remedy to my problem after searching the Web and watching some youtube videos. THERE WAS NO DOUBT ABOUT IT. Installing the software was pretty simple. On YouTube, you can find many videos that will guide you through the installation process. for the quality, I can only say it looks and feels exactly the same as the OEM one I swapped out of my Mac.
My computer made a full recovery when this product was installed using an online video tutorial. Although the installation was more complicated than a typical RAM upgrade, it worked after that. The only way to know whether it will last over time is to use it every day.
I tried booting the old A1278 MacBook Mid-2010 When I clicked on the blinking folder with question mark, I received a message in 2012. It turns out that these HDD cables are notoriously touchy and can fail without warning. The problem was solved by replacing the unit. You will need to record the model number on the back of your existing cable (it's on the backside of the ribbon cable) because there are two versions, so you won't get the incorrect.
This cable does need to be bent, but other than that it works flawlessly and if you added the SSD cover, as I did, then it adds additional stress to it, making the original one fail. However, this works great and I will purchase again if I.
Having replaced my MacBook's cable twice (mid 2012), this is the second time I've done so. The laptop can still be used if the issue is easily fixed. This is a problem with this line of laptops.
Integrated perfectly, works great, and spared me the expense of a new laptop or an expensive repair. Buying this was a good decision.
The new cable works perfectly with no problems after opening up the laptop, removing the old one, and replacing it with this one. Fix it yourself for a low cost! The computer now functions as if it were brand.
It happened one day that my Macbook wasn't able to detect the hard drive. We found the solution to it in this way. Don't waste your money on a new laptop without doing your research.
