i have a MacBook Pro "Core i5" 2.5 13" Retina 2012 that lags everywhere, in the apple diag it passes everything, and yes i chose the full diag, 3 times. i see no reason for the major lag. tried new harddrive with a fresh el capitian and nothing changed. i come in today to work on it and now it wont turn on, for a few it acted like it wanted to turn on. "fans spin up no dong or screen" then it just stopped even trying to turn on. i get the amber light, but nothing even when i jump the power pins. what should i check first. i dont see how it just "gives up" going from super laggy to stop turning on.
