Hello everyone! I have a macbook pro late 2010, 13". I have it hooked up to a monitor and i use apple keyboard and trackpad. it almost never moves, or even gets unplugged. I opened my computer today to blow the fan out as it collects dust and i do not wanted to over heat.I do this once a year. When i took the cover off i noticed were the power cored plugs into, the plastic looks burnt. The computer is running well, but do these plugs usually go bad after a while. I have some pictures tell me what you think. Thanks!
