I have a late 2008 MacBook Pro. I was having problems with the speakers sounding distorted and I read online about a fix you can do with rubber cement. I followed a guide on iFixit's website and put the glue on the speakers as I saw others do online. I waited a few hours and put the computer back together. At first it seemed like it worked, the speakers sounded great and I had no issues. Later in the day I moved my laptop and set it down and the wifi suddenly stopped working. It said something like "WiFi: No Hardware Installed". I did turned the computer off and opened it up to make sure nothing was loose or looked unusual. I then did some googling and tried a few fixes (resetting the NVRAM & SMC). I tried to turn the computer on again and it made no difference. I turned it off and turned it on again a few days later when I had time and now the computer won't even turn on. When I hit the power button it sounds like it's turning on and it does the "chime" noise but the screen remains black. I've tried a few things for this as well (PRAM & SMC reset) and nothing makes a difference. I think I obviously messed something up when I tried to fix the speaker but I don't know what or if it's fixable. Any help would be greatly appreciated.
