I’m trying to figure out the repair my macbookpro 15’ mid 2009 3,06GHz needs:
-blacks on the display turn green, pressing the case sometimes helps
- fans turn on maximum after just a few minutes in operation.
otherwise the computer works fine. Still on OS10.7.5
much appreciated if anyone can help me diagnose
a newbie
