I recently noticed that my MBP heats up and the fan goes on (just like when viewing flash) even with light surfing on the web, e.g. posting a thread on this forum, the bottom is hot and the fan is on. I have one program open which is the safari and it's really annoying. Furthermore, I noticed that the battery life is not as good as when I first got it. 100% charge will last me 2 hrs. It's less than a year old. Any possible solutions, or should I go see a genius for this?
