My MacBook Pro will not turn on again. I just received it back from repair last Monday for this same problem.
It was working just fine. The battery was getting low, so I went to the other room to get the charger, but when I got back the computer was turned off. I plugged it in, but it still will not turn on. I have also tried reseting the PMU. This does not help, and did not help the last time.
I am so upset that it is broken again. I will have to wait another eight days to get my computer back again. This is not the first time I had problems. When I received my first MacBook Pro, only two moths ago, the back lighting did not work. This computer has been a lemon.
