i7 processor, maybe a mistake?

never exceeded 65c on my 15" 2,4 i5.

Right now I've opened Skype, Safari (with 7 open tabs), Chrome (running a movie trailer from apple.com), mail, 3 finder windows, iPhoto and iTunes; the 330m is engaged and CPU temp is 62c.

Machine is on my lap, not unconfortable just a bit warm, and room temp is 20c.

Mine gets hot when the 330M needlessly kicks in. Many programs and situations trigger the discrete graphics. One stupid example, the chrome "incognito" window turns it on... why? Apple needs to look into offering a manual solution. Otherwise this is the coolest laptop I've ever owned.

Try gfxsolutions. It's at this link: http://codykrieger.com/gfxCardStatus/

The graphics switching is still labeled "experimental," but I tried switching back to Intel graphics with an incognito window like you said, and I had no issues whatsoever. It's a great little monitor anyhow, because it lets you know which card is running in real time.

I admit to have spoken glibly when saying "good for" the battery. You're quite correct, it shouldn't be done too often with Lithium-based batteries.

It is indeed a good thing, however, to run the battery down occasionally (maybe every other month or so) rather than (for example) leaving it plugged in all the time.

Best yet, per Apple, is light cycling with the aforementioned occasional deep discharge. See http://support.apple.com/kb/HT1490 and http://discussions.apple.com/thread.jspa?threadID=1764220

The occasional deep discharge fine tunes the calibration and accommodates aging of the battery. In my own experience (and, admittedly, this is anecdotal) the battery-meter accuracy is improved significantly by at least a second calibration discharge within the first month of usage. But this might be overkill. I'd imagine the calibration would be further finessed if the discharging is done during normal usage rather than putting the machine on a desk and letting it run until it dies.

In any case, my February-issue MBP's battery meter is scary accurate now. And my occasional deep discharge--either purposeful or on a long flight--should keep it that way.

I did a calibration on my new machine last weekend. It doesn't read nearly as accurately as it did before. It used to say 100% when totally charged...now it says 98% and always like 15 minutes left until fully charged but it says "charged" by the battery icon. I am going to calibrate it again to see if it will fix it. But the first calibration didn't help at all really. I'm not worried or anything. I still get good battery life and such just not the most accurate read out.
