I have a MacBook Pro that isn’t working properly. The screen when you flip it up shuts off when it gets past a certain degree. We contacted Apple and they said it’s something with the hardware which I know nothing about. They recommended a certified Apple repair shop in Fort Mill that would need to take the computer for 3-4 days to fix. This is my only company computer that I use every minute so hoping to find a better option if possible.

Sorry to say I don’t do hardware repairs. Yes, the problem you are describing is 100% a hardware issue. There is a cable that goes from the display to the main logic board that, as you open and close the display, the cable flexes and over time can bend so many times it goes bad. Think about it as if you were to bend a paper clip back and forth many many times. The paper clip would break. That ribbon cable is most likely the damaged piece. I wish I could help but I no longer do physical repairs due to the time involved, liability, and cost/profit margin.

I realize how tough it is to be without one’s computer. The good news is that the computer itself is probably fine so in the short term you could just connect it to an external monitor and continue working until time permits for you to be without it for several days. No one will be able to turn that repair around in hours or perhaps even over night. It’s pretty involved.
