I changed my macbook pro house cover, after changing it, my screen wont turn on, also the apple logo wont light on. I heard the computer turn on but the screen doesnt light on. the keyboard wont light on too. Please help me. What did I do wrong?
Hook it up to an external monitor to try to isolate the problem. A history might help us, why did you replace the case? Which case was replaced? Did it operate before you replaced the case?
