Solutions as to why my MacBook Pro won't power on?
Earlier today I was using my MacBook Pro and was getting irritated at how hot it was getting underneath even at idle. It was running fine and has been ever since I purchased it.
After reading up on reasons as to why the computer would be excessively heating, I figured an inside cleaning would do the computer some good. Following iFixit's guide for takedown, I was able to clean the dust out of my MacBook Pro. I only went as far as removing the logic board so I could wipe the dust out of the bottom of the case. The fans were pretty dusty as well, I took care of it.
As a note, I didn't use a wet cloth, I just took a paper towel and folded it into a small square being careful I didn't touch anything but the case. The dust in the fans I blew out with a can of air; only after disconnecting.
Upon putting the components back together, reversing each step in the guide; the MacBook Pro will not power back on. I've checked each cable to make sure it was properly connected about 5 times over...nothing.
I've tried to reset SMC.
I've held down CMD+CTRL+Power.
I've checked each cable.
The only cable I can really think of that would be a problem is the flex ribbon cable for the keyboard. It doesn't seem to "lock" into place, but rather sit there. It's being held in by the bracket.
Anyways, I'm freaking out here hoping it's not the logic board, but I fear the worst. The charger light comes on, the battery charging indicator works; even with the button press. However, it's just unresponsive when I press the power button.
