Okay, so this morning I had taken my MacBook Air out and turned it on. At first, the only thing I was seeing was the keyboard lighting up but nothing else. So I turned it off with a hard reset. Then when I turned it on, I could only hear the charm and the backlight appears, although there is no display. I don't have access to the mouse, the keyboard does not light up, nor does the shift button. So far, I've tried Turn off the Mac Disconnect the Power cable Hold down Shift + Control + Option and Power button at the same time for 12 seconds Release all keys at the same time, then reconnect the Power cable and turn the Mac back on again Next, reboot the Mac again and this time hold down Command+Option+P+R keys concurrently for about 20 seconds, this resets the NVRAM Still no luck. Now my friend told me to reinstall the operating system. As I haven't tired that yet, I don't think it's going to work since I don't have a working screen to show me anything?? Anyways, I don't want to take it to apple care because god knows It's going to be expensive. >.>. If I could get any support, that would be great! OH!!! I should also let you guys now know that this started happening right after I updated to the newest OS X. This is a MacBook Air 2013 MD711LL/A Please please please help!!!
