Hi guys, I have a 2009 13'' MBP and lately I've been having overheating problems when I start to charge the computer. I first thought that it was because it was in use for 5 hours continuously. But now at the first hour it overheats. I don't have any flash webpage open, or any background app that could lead to a CPU overwork. Would appreciate any tips or ideas of what can be happening, thank U!
