Macbook Pro working really slow

내 문제

The Macbook Pro was working really slow. My first thought was a failing harddrive, so i took it out, at did a test, no error. Then i thought it might be that ribbon cable. Since i live far away, i wanted to order from ifkxit because of my previous success with them. It took only 6 days to receive the package ( which is pretty impressive by the way), and everything was of course in order :)

나의 수리

I replaced the part, and everything is working properly. The customer has paid, and we both are happy with the fix

If these Macbook Pro's are working really slowly, pay close attention to that ribbon cable. I have expeienced it quite often that the issue is with the cable and not the harddrive it self.
