I had received the Macbook free from my sister because the screen wasn't working properly. You could only read it at certain angles. My sister had gone to Apple to see if they could fix it, but it was going to cost $300 dollars. So, I got the broken computer. I did some research, found iFixit and was extremely surprised to see that I could possibly fix it for about $20. The info on the site made it easy to diagnose the problem. I ordered the part I needed and waited.
Two days later, my packaged arrived in perfect condition. I immediately set to work and an hour and a half later my Macbook was again fully functional. The Guide on installing the inverter cable was easy to understand and the process went smoothly.
Take apart the Macbook first to see the inside before ordering/installing the part(s). I did this and I am glad I did. Otherwise I would have ordered the wrong part. Plus I got familiar with the inside making the actual install much smoother and easier. Oh, and go to iFixit before you go to Mac, you might just save $280.
