Hi, My 2011 13" base model for the past few months has occasionally been acting up. The CPU randomly, even when my laptop is idle, will just start working super hard. I notice because the fans would crank up to 6000rpm, and i check iStat and see that the CPU is running at 100% running nothing but iCoreServices. I can run other programs normally, but the fans will always be running and the CPU never seems to stop running at 100%. I have left it idle for at most 15 mins at one time and it still continued to do the same thing. My only option everytime it happens is to hold down the power button and shut it off manually because it is just stuck on a blue screen when i try to shut down or restart. This has happened about 5 times since I got the laptop in March. Anyone know what's up?
