Although it is sad that the coverage has ended, there is a way to keep the computer going. it isnt permanent, but It can theoretically be repeated, so you could get another year or two out of you MBP. Just try this:
1. Plug in your macbook pro (make sure that its off)
2. Turn on the computer, and hwen it chimes, close the lid and turn it updside down.
3. Wrap the macbook in a heavy quilt.
4. Let the computer sit for about an hour.
5. Take it out of the quilt, unplug it and let it cool for 20 minutes.
6. Turn on the computer.
I can say that this works as I had the same problem, and after this method, the computer is up and running, I'm typing this on it now!
Now stop complaining! its 5 years old, try this or just suck it up and get a new one!!!
