Black screen - HD works fine
Working fine then closed it came home from work and no screen. Nothing, black, no logos, nothing. Been researching but cannot find conclusive answer.
-Black screen but HD still works fine
-Pram and smc reboots do not work
-external hdmi monitor shows full OS X without issue (backed up to time machine) but does not show the laptop display in display preferences
-brightness keys do not respond
-nothing plugged in, besides hdmi for monitor
Have appt with "geniuses" tomorrow but would rather get info from this forum before.
