Resposta para "Black screen and fan revs no chime"My early 2011, 15” A1286 has the black screen and no chime. Someone suggested rubbing across the keys while power button is pressed - this occasionally got the fans running fast - no chime or display still. Previously, I removed the logic board and cleaned the heat sink surfaces on the GPU and CPU etc. I heated the GPU in case this made any difference. New Arctic Silver paste, reassembled, no difference. Watching this forum for answers… For what it’s worth: my other workhorse MacBook Pro, late 2011, 15” suddenly got the grey screen halfway thru booting - I found a guy on Youtube who showed how to bypass the faulty GPU, holding CMD/S then power button, then a whole bunch of terminal-type commands. I still use this machine happily, without much loss of resolution.
