Why won't it boot?
I'll try to keep this brief, but it's a rather long winded story, and unfortunately I believe all the chapters are of relevance.
So let's get started. It all began when I poured s glass of wine onto the keyboard, which was replaced by a pro. Worked for about 6 months, then it would start to boot, then cut out. Before it died all together, it would take anywhere upwards of 20 presses in the power button to get it to boot completely. Took it to another pro, had a chip replaced on the motherboard.
About a month later, it started showing the same symptoms as before. Now what is weird is that the first press would get so far in the boot process. But the second would cut our straight away. 3rd would get a little further, 4th would die straight away, 6th a little further than the 4th, etc, etc, I'm sure you get the idea. I really got the impression that the computer needed to warm up, as this only seemed to happen when the computer was off overnight or for a long period. It would restart without a hitch if it had been on for a while. Towards the end, it would turn off unexpectantly during use, but this was very rare.
Now I was able to try the battery, hard drive and RAM in another (working) MacBook Pro, and they all tested fine. I tried the motherboard in the working Mac, but not surprisingly, that didn't work. I took it into Apple just before it stopped booting all together, and they said there were no detected hardware errors.
The DVDs drive wouldn't read DVDs or CDs anymore, but would burn ok if I forced it onto it's lowest speed (I don't believe this to be related). Also, the Status Indicator Light cable wasn't working (again, I don't believe this to be related).
I appreciate any light you can shed!
Here's some noticeable damage on the motherboard
Here's another one, although maybe it's just from fixing the chip to the motherboard??
Is this a good question?
