This is more for those that use their MBPs in closed lid mode with an external monitor consistently. I have a home-studio setup where I connect a larger monitor to my MBP while it sits with its lid closed and do audio work (CPU intensive), and I'm sure it gets pretty hot. I don't know what is causing it, but the computer has been unusually unresponsive and slow lately. I thought it may have been due to Leopard updates and Logic updates. I opened the lid the other day to turn the computer on and I noticed something unusual at the base of the screen. There is black ash on my computer!! I mean, it looks like my computer caught on fire! Have any of you ever experienced this? The computer works OK (not great like it used to). Everything seems to be working, but Logic is incredibly slow and unresponsive. And it just generally seems like the computer is working harder than it used to for the things I have been doing for the last 6 months. Any of you have experience with this? This is my THIRD MBP from apple. All have needed to be replaced by the previous. Each has not lasted longer than 6 months.
