Why is my MacBook Pro laptop not turning on at all
I have a Macbook Pro 13" Retina Mid 2014. It has been working perfectly but the othe day it refused to turn on, it was like my battery was completely drained. I charged it for a while (orange light came on charger) but still wouldn't turn on. I put it on a different charger and let it charge over night until the green light came on to indicate battery was full. Still no sign of anything happening when I press the power button. No sound comes out at all, and caps lock light doesn't work (to show me not just display not working). I have tried holding the power button for 10 seconds. I also tried holding pwr
+ shift+cmd+option for ten seconds, when the charger light was orange it briefly turned green when I did this last action and then went back to orange, but nothing else happened as a result.
What fault could possible test this and how would I determine which part to replace. I feel confident with the guides on this site to replace the part, but need some guidance in diagnostics. Any help would be greatly appreciated.
