Chosen Solution
I followed the step-by-step guide on iFixit and also looked up a couple of YouTube videos. The charger stays green but the computer won’t turn on when pressing the power button. Pressing the power button and shift + control + option keys also isn’t helping me. What else could I do to get my machine to turn on? This isn’t my first time attempting to fix my Macbook. A few months back I changed the HDD to an SSD and didn’t come across any problems. Thanks in advance!
OK, so you have a dead system! Which is a very different issue that changing out the SATA cable won’t have any effect. Disconnect the HDD SATA cable from the logic board connection to verify you haven’t damaged something. I’m suspecting you have a logic board failure.
Hi @danj, I know it’s been a while but I was hoping you could still help me/share some advice! If my computer is recognizing the SSD with the original Apple SATA cable that came with my computer, is the SATA cable the problem here or should I do something else to improve speed and performance? The computer operates fine but will start slowing down after some time if I want to do multiple things at once – like watch a movie Netflix on AND web browsing. Thanks again!
I have a very same issue: The old HDD cable failed on my MacBook early 2011, so I purchased a new one. Connected it and MacBook would not turn on. Removed it - it works fine and turns on. Add it again - no life at all. So I opened another Macbook early 2011 which is fully working, disconnected the original HDD cable and connected this one (exactly the same models) - it would not start up at all - no life, nothing happens. Remove the new cable - starts as usual, no issues. So I have asked the seller to replace and I will update you when that happens. I suspect the cable is faulty.
