    My brand new MacBook Pro, which is only a week old or so, runs hot when idle, and by hot I mean 75-80 C.

    What I am doing? Browsing the web. I got my screen dimmed, got nothing special open. No bluetooth on or whatsoever. Just browsing the web (Safari, sometimes Firefox) and using Adium. That's all.

    When? Doesn't matter when. When wireless in better batter life, when hooked up with adapter with better performance.

    What is wrong?

    There are a lot of factors that can determine it.

    I've found that while running FireFox, it tends to run about 70C. 'firefox-bin' is generally taking up a whopping 20% of my cpu, so I generally stick to Safari.

    Also, for me living with no air-conditioning, it also runs a little warmer than normal.

    Screenshot

    At this moment, All I got running is Safari. Got my laptop in better battery life and on battery, and here's a screenshot of my temps:

    I had the same problem... check the temps with AC plugged and with no battery embedded on. If you find regular temps maybe it's a logic board issue like for me. Did you make the 1.5.1 EFI upgrade? i'm starting to think there's a connection between my problem and this update.

    Another parte of the issue was a huge loss in battery performance too.

    (Please forgive my english, is rusty!)

    I really don't understand my prob. First week no problems. Fine in college...lasts 4-5 hours.

    Next week (this week) problem started. I didn't have to update my mac, so 1.5.1 EFI must've been on my mac already.

    Your logic board appeared to be broken...?

    (Your English is fine :))

    It is very likely that your computer is perfectly fine hardware wise, you're just having a software problem somewhere. Open up "Activity Monitor" in your utilities folder, click on the CPU tab and make sure you have "all processes" selected. Then look at what's increasing CPU usage. You should take a screenshot of it and post it here, but you can just force quit the process that's eating too much cpu.
