Hey, I'm new on these boards and will soon be the proud owner of a Macbook Pro. I just had a quick question about how hot the new systems get. I can see myself using my computer all over the house...will I need a desk to put it on or will it be ok to put it on my lap/other fabric? I really don't want to cause it to overheat and cause strain on a brand new system. Any info/experience is appreciated.

Most computer manufacturers have stopped referring to their portables as "laptops", instead using the term "notebook". This is because they are not designed to be used on your lap. You should consider buying a lap desk if you intend to use it on your lap on a regular basis.

With that said, the most current version of the MacBook Pro doesn't run terribly warm and I don't find it to be uncomfortable on my lap.

Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

i would say it probably depends on what you are doing. if you are just browsing the internet, using aim, word processing, or basic things. you should be plenty fine with it on your lap. but once you get using more cpu hungry apps, such as photoshop, or movie editors, you should put it on a lap desk or something.

I use mine in the bed all the time. It's great for those late night Mac-Forums sessions! It does not get hot at all really just doing basic internet stuff. I wouldn't try photoshop or any thing like that though, as ki99 has already pointed out.

That's reassuring I use my mac a lot for simply staying connected with people via facebook/chat, which I do a lot of at night. So being able to chill in the bed instead of in the living room is part of the excitement.

Just keep in mind that ALL modern notebooks get warm on the bottom - it's completely normal. If it gets uncomfortably so, it might not be a bad idea to move it to a flat surface.

I've taken a temp reading using the istat pro widget. The base of my MacBook Pro is holding steady at 81 degrees Fahrenheit or 27 degrees Celsius. It has been running for about 2 hours with Firefox and mail running. If some other users post their temps here you should get an average of what to expect while web surfing and emailing.

Edit: This temp was taken while the MBP was sitting on table top. I will post more temps later tonight after I use it in bed for a while.

You're really running cool. Mine is on a ventilation stand on a desk and my "Enclosure Bottom" is running at 97 degrees F at normal usage. Usually the hottest part of my computer is the graphics card, which during normal internet usage, runs at about 140-150 degrees F at the GPU diode.

Mine runs at about the same temperature as Barbanette. It's been on my lap for about 2 hours now. Running a mix of Mail, FF3, Preview, Cyberduck and Adium. Right now, the reading is 83 degrees Farenheit at the bottom of the case.

Even my original Yonah/Core Duo MacBook Pro ran pretty cool. I think it has a lot to do with how they apply the thermal compound at the factory. It's been found to be overzealous on certain machines.

Bingo! I actually pulled my original Core Duo MacBook apart removed all the thermal paste and applied a responsible amount of Arctic Silver ceramic thermal paste to it because of heating problems. I would have done the same with my new MacBook Pro but thankfully it wasn't necessary.

EDIT: I have been using my MacBook Pro in the bed with the bottom of the case on the comforter above my lap for about an hour and a half now. The temps are a little warmer but still not bad at all. 88 degrees Fahrenheit 31 degrees Celsius according to istat widget. But the outside of the case does not even feel this warm.

and if im playng something like crysis in the room that temperature in it is about 30C and the heat will rice until 85-90C the computer will turn off?
