My all aluminum MacBook Pro is heating up when I use it. I already replaced the battery, no difference. It gets so hot after an hour or so I have to put it away to cool because it almost burns my legs.

Heat is the enemy of electronics, and it doesn't do me much good either. Is this 2 years old MacPro heading for self destruction? Or, is there anything I can do to keep the operating temperature down?

This is the first all aluminum MacBook, and the design was changed (different battery amongst others) not that long after it was released - hope that helps. Thanks for your help.

    If you are working the machine hard, it will get hot. If you aren't (at least not knowingly), then something you're not aware of may be running on it, generating lots of heat and draining your battery rapidly. If that's the case, this article should help you identify it:


    If you're well aware of what's causing all the heat and you need to keep doing it, get the machine off your lap. Using it there reduces cooling efficiency, and of course using your lap as a heat sink isn't comfortable, either. The MBP is designed to have a thin layer of free-flowing air underneath it at all times — that's why it has those rubber feet on the bottom. Use it on a hard, flat surface at all times. If you must use it on your lap, set it on a board or a laptop cooling pad.

    Changing the battery couldn't have made any change in the machine's temperature, and was unnecessary unless the battery needed to be replaced for other reasons.

    Thanks. There is a proces called "iavd" in the root that is taking 08% of the run time. Could I just quit iavd without doing other damage?

    Oops, that should have been "98%" in user root.

    I disabled it, it was an antivirus program I recently installed that I now have removed. Thanks for the help!

    i had the same problem but I picked up a cooling stand which has 2 fans on the bottom which keep it cool and I havent had a problem since! Check it out

    Yes, iAntivirus is notorious for that. You don't need antivirus software, so don't bother to replace it with anything else.

    I agree that the macbook pro gets too hot. I've got the 15" i7. I've noticed it takes very little graphic usage and the temps get very hot. Charge the battery and watch a netflix movie and it gets really hot. If that's acceptable by design they need to change the specs! I'm surprised to see the comment of don't use it on your lap?? It's a "LAP"top...seems like a design weakness if you can't use a LAPtop on your lap. If I've got to place it on a board, a flat surface, or something with fans isn't that a DESKTOP? I think the design folks need to assume a laptop is used on your lap and get the temps lowered to a more reasonable level. I also bought the twin fan cooling pad and I've learned for any video graphics you must use this or it gets hot enough to hurt your skin. At home, I'll use the cooling stuff but when I travel or on a plan I don't want to carry all of this stuff.

    When you really need to use the machine on your lap (e.g., on a plane), use [gfxcardstatus|http://codykrieger.com/gfxCardStatus> to prevent the NVidia GPU from being used, and it will run 20-40° cooler.
