Well, my Macbook Pro is heating, quite bad I must add. I recently got that annoying gray stain behind my screen, took it to the Genius Bar and they fixed it, I just thought that it's worth mentioning that. At the moment, I am running Firefox and that's it, I have nothing else open, 2 tabs, digg.com and macrumors.com. The Laptop is sitting on a glass table with nothing behind it, so there is room for some air ventilation. I'm also using a Speck SeeThru clear hardcase. The problem I am having is that the MBP is heating up real bad, to the extent that I'm feeling it (and im sitting on a chair with some distance from it). I really don't understand whats wrong with my mac, it takes ages to start and load everything and the heat is bad. What's worse is when I asked at the Genius Bar what the issue was, the reply I got was in regards to me having Photoshop and so many "3rd party" software, and when I asked about the heating, the only reply I got was that softwares like photoshop and illustrator are memory intensive... even when I tried explaining that it over-heats even when I'm not using it. Any help or suggestions would be quite welcome, I understand it heating when I'm using a program like that, but over-heating when I'm only using Firefox? or just watching a Movie? Mac: Intel Core 2 Duo 2.4Ghz 2GB Ram GeForce 8600M GT (256MB). And the room is well ventilated, and can anyone also tell me what is needed to be done if I wanna upgrade my Mac (say add more ram and so on?) Thank you, and sorry for the lengthy post.
