Turned on my Macbook Air this morning and was greeted with a black screen, I could vaguely make out the login screen but when I entered my password the screen went completely black. I tried restarting and booting into safe mode all to no avail. I guess this also means I can't run Apple Hardware Test to see if that shows anything. I've got it connected to an external display at the minute which is working fine.
Is there anything else I can try to fix the issue from my side before taking it to see a genius.
