Hey, all.

That's the figure I just obtained using a digital thermometer on the bottom of my brand new 1 Ghz PB 15. It was smokin' hot last night, and it's smokin' hot tonight. In fact, my upper thighs have red spots on them (through jeans, no less!) Fortunately, the place where I bought it here in NYC has a liberal return policy. Will someone please tell me their new PB 15 is cool on top AND on the bottom? There's absolutely no way I can work with this thing on my lap.

The sad kicker: The screen is absolutely perfect. Zero white spots. Same with the latch: works like a charm.

FWIW, Temperature Monitor in OS X has CPU running at 44-48 degrees Celsius, getting up to 53 last night.

Anyone else having these problems? Are other running cool?

I have a new Albook 1.25GHz and I have not had any heat problems. I have put it though a lot of hard use so it's not like I never push it. Take yours back and exchange it.

I don't speak from experience, just curious... isn't that barely above body temperature? Is 99.7 degrees actually painful?

My old PBG3 gets very hot--on soft surfaces. Never measured it though.

Yup mine is like that. Under normal usage such as the web and everything it never gets that hot.

But the other day, I was watching some movie clips, running photoshop, and with ripping CDs in the background w/ iTunes and it was really hot on the bottom end. Energy settings was automatic.

I'm not sure if you're running off battery or if you have it plugged in but here's what I've noticed. If you have the power management set to reduced processor power, it doesn't get too hot on the bottom. If it's set to "Highest" then you'll get a noticeable increase in heat and decrease in battery life. I switched mine to Highest the other day while I was batch resizing some images and forgot to switch it back. Battery life was horrible and it got toasty!

I usually get 3:30 on reduced with half display brightness.

If you've got it plugged in I'd recommend you use it on a table. If it's getting this hot on the Reduced setting it'd say take it back.

Sounds like others of you are having the same problems.

I tried the reduced processing option and it still crept up to 46.8 degrees C.

I haven't heard a single fan come on since I've had it -- I wonder if that's the problem? Is the fan audible when it kicks in?

p.s. Just did another check -- 101.7 degrees F on the bottom. This can't be considered acceptable.

Check with the place where you bought it..

[Greasyboy]

Maybe I'm weird...but 100 degrees doesn't seem that hot. 120 degrees, well that's a problem. But 100? Isn't that barely above warm?

I always work with my PB on my lap. I tried everything to keep my legs from getting hot. I ended up buying a cooling pad from Hardcorecooling.com. Although the quality leaves a lot to be desired, it does the job great. http://www.hardcorecooling.us/product.asp?3=529

Thanks for the input, everyone.

And I assure you, 101.7 is hottttttt.I think it may be one of those things where your body heat, plus the heat of the unit, is the actual heat -- you know, it's nice to be outside when it's 70 degrees, but when it's 100 degrees, it sucks, even though your body temp. is 98.6.

The cooling pad looks nice, but as long as some folks out there are reporting functionally cool 15-inchers, I'll just take advantage of the return policy.

Again -- has anyone audibly noticed fans kicking in? I'm stil wondering if they just aren't working properly on mine.

They do get hot under heavy use....

I mean that literally. The more intense the usage of the CPU/drive, the hotter the machine.

Those using Word, coding, text-ing and web-ing will probably not have the machine get hugely hot.

Those going out and playing games, rendering vid/3d, etc will get warmer machines.

That simple.

Users have been all over the map as far as heat issues since the Wallstreet PB's... too hot, scorching, just fine, ice cool, etc. It is a nuance of mobile computing. People just need to chill out (he he) and just realize this. These things consume X kwh, generate heat, it needs to dissipate and the materials used only absorb so much. The laws of thermal dynamics apply to Apple as much as everyone else.

It is no different in the Windows world either, I'll tell you.

So is it hot, yeah...maybe.

Is it busted or unusual...no.

FWIW,

Heh, that's pretty cool compared to a Dell Inspiron 8600 I used recently... 130+ on the underside, 100+ on the topside near the hinge. Even the palm rests were 90-95.

There's a reason they call them desktop replacements... I sure wouldn't want to have that thing on my lap.
