Default MacBook folk: Help with hot laptop

I had my battery replaced under warranty yesterday because it wouldn't hold a charge, and even if it did, the computer was shutting down at 80% power and wouldn't turn on unless I plugged it in. I thought that'd take care of the REALLY HOT laptop issue, but turns out the back is heating up, between the battery and the LCD hinge. iStat says some things are running at 139 degrees fahrenheit! Short of going back to the Apple store, is there anything I can do to cool this thing down?

I have a MacBook Pro and also use iStat. I got concerned when I saw the temp was up, at times, to over 165 F. My oldest son is a Mac Creative and he checked with one of the tech people at work who told him that temps up to 185 F and higher are not that uncommon. If you are still under warranty you should be able to do an iChat session to get some advice I'm just passing on what I was told.

So long as it's normal and not doing any damage, I'm less concerned about the computer. I'm more concerned about my poor lap, though. I've got two blankets between me and the comp, and i can still feel the warmth. I may call Apple Care and ask if it's worth taking in. I know sometimes a program could be running hot, and once that's shut down (sometimes it's as silly as a printer thing), the temp drops. Thanks!

Here are my current iStat readings. My son says the MacBook is not really marketed as a "laptop" because of the case heat. If I use mine as a true laptop I use a small lap desk to protect my legs from the heat. I REALLY hope the screen shot I took is visible !

Thank you so much. You've made me feel so much better. Mine's running a little warmer than yours is right now, but not by much. So long as I'm not frying my computer, I guess I'll just cope. I usually use a pillow when I'm on a couch, and on the bed, either pillows or blanket. It's still a problem, but a normal one, I guess, which is fine, or as fine as it can be.

The pillow or blanket may be making it worse, you might be adding heat. You can get a lap desk for a few bucks, use a TV tray, or make your own lap desk out of a piece of scrap MDF. The flat, non-insulating surface is much better at dissipating the heat than a pillow or blanket which absorbs the heat and transmits it back to the laptop. In a pinch I have used a large book to support the puter without increasing the ambient heat. I would still do an Apple Care because I know it made me nuts that my fans would spin at 6K revolutions at times. I really thought my puter was going to melt down (or blow up). There is a way to see if your puter has logged an overheating event but I don't remember it right now. I'll ask my son and PM you with how to check.

Good point about lap desk. I actually plan to keep it on the table, once it gets here. I've been without furniture for more than a week with the move, but it'll all get here tomorrow. I'll see if a surface change makes a difference.

I use this lap desk with my 3 year old iBook and love it. It seems to dissipate heat really well and it puts my laptop at a comfortable height. (It's $6 cheaper at Target than on Amazon, but Amazon has a better description so I liked to that one.)

Thanks! I practically live at Target, so I'll check it out when I'm there! Keeping it on the counter helped cool it down, too. I'd been using it on my bed for the past week.
