    I have a mid-2009 MBP (13" 2.53Ghz core 2 duo, 4gb ram) running 10.6.8. I have been having some trouble lately - it is getting quite a bit hotter than normal (istat tells me it its about 80 degrees near the CPU and a bit less than that in heatsink B). The fans have not been turning on (I'm not sure how hot the computer needs to get for the fans to be on - but istat tells me they're not on, and I definitely can't hear them!).

    Just earlier I got this in Activity Monitor (pic attached). The computer was very slow across all applications - this picture was taken once I'd shut down word, preview etc and just had safari. I'm not sure what that kernal task is that was taking up so much power.

    When I repaired disk permissions it was (when I copied the log across to word), 427 pages long!

    I am also posting to here using firefox, because safari kept on hanging and couldn't type into the forum (although the slowness seems to be affecting most programs eg. word).

    Does anyone have any idea what the problem could be? should I be worried or will the problem rectify itself? Any advice on what I should do? I am still in apple care warranty, and the hard drive was replaced a couple of months ago because it was failing.

    Since you're under AppleCare, bring it in. If that kind of kernel usage survives a reboot, you probably have a bad logic board.

    Your one and only fan will always be spinning.

    You wasted at least several minutes of your life repairing permissions that you will never get back. People have been feeding you superstition. As a tech, I virtually never repair permissions because 99.9% of the problems out there are not caused by permissions issues. It will fix permissions problems. Anything at all relating to speed and responsiveness is not going to be a permissions problem.

    high cpu usage

    Check to see if you have Rapport, from Trusteer installed.
    Its some kind of security software that my bank wanted me to install. It did the same thing to my I-mac. Many people are having problem with this software.
