There is no way that I am opening up a macbook after I buy it - I just upgraded the drive in my G4 mini, and I am sure that I took a few years off the life of the plastic parts by doing it, and I lost a couple of the screws.
I was waiting until Janruary anyway, hopefully all the issues will be worked out by then.
I went to the local Apple store to check out the MBP. It was the first revision. It had the whining sound, and it was REALLY hot. It had Safari and mail running. So no CPU/GPU demanding tasks.
I felt on the top where the CPU, GPU and Northbridge is located. The GPU wich is in the middle i think, was extremeley hot. And the whole case was uncomfortable to touch when typing.
I then went to another store that sells apple computers, and they had what the guy in the store said to be a revision 4 MPB. I listened closley and I heard no whine, and it didnt feel anywhere near as warm as the first revision.
Is this problem fixed with the latest versions or what? Or is it 50/50 that you get a crappy one with whine and heat problems?

I modded in a 5400rpm drive into my iBook g4 933mhz and also wound up with some extra screws, the left speaker died, and the ports of the left have some plastic edge that doesn't quite sit flush. But it's Snaptastic with the faster drive and meh... the 3 year AppleCare ends this November.
There is something wrong with the USB ports (doesn't work properly with my Canon scanner -- it did work last month but now no dice) but the iBook is too valuable in its daily use that there's no point taking it in to AppleCare.
Plus the modem was busted (before I did all the mods) and they refused to fix it, saying it was "burn effect" from lightning although we clearly never used the iBook laptop during a lightning storm/heavy rain... WTF
Taking apart an Apple laptop I would say, definitely requires skillz to get it done right and end up with exactly the right number of screws ie. not one more nor one more less.
hopefully apple is paying attention to what users are finding and yelling at the manufacturers to fix what they're doing and to follow the users lead as to how much thermal paste...cause if they can get such a significant drop in temperature, they'd have a lot more happy customers
Any idea what's causing the whine issue? We seem to have got the heat issue sorted out, now let's work on the whine issue..! Modders start your engines and rip apart those whiny MacbookPros and report back to us
Is the Whine and the Heat related somehow or are they separate issues? What do you all think?
I just got my MBP and I noticed the heat, almost burns my hand when I touch it, BUT I don't know what this whine thing is...mine's pretty quiet. Maybe it's because I haven't used it for much other than internet and excel/pdf/word stuff.
With the Titanium G4 and Alu 15" G4 I've had I don't recall any heat or whine issues. Only with the Titanium G4 you had to put a piece of cloth to prevent the dreaded "keyboard marks" on the screen.
Hope you Macbook Pro people eventually get your heat/whine issues sorted out \

The whine sound is caused by the power supply. The Intel chip is always looking to minimize power consumption when on battery power. Because of this, the power level is constantly changing, which causes extra work for the power supply.
Somehow the changing power levels causes the whining sound. The whining sound goes away when raising the CPU work levels because the power supply requests stay at the same level (high).
This is why opening programs and such cause the whine to go away. This is also why the whine happens more frequently on battery power. While plugged in, the CPU doesn't have to try and be so power efficient so it isn't constantly trying to power down.
I found a website that went into the technical details behind this whining phenomenon but I don't have that link available anymore.

The fans probably spin extra fast because the RPM is measured by average.. thus it immediately thinks the average is way low and tries to offset it. I bet if you got the thing real hot, the whine would be constant.
It has nothing to do with the fans. It's an electronic noise caused by a voltage transformation. Keeping the CPUs just busy enough to stay out of their deepest sleep mode prevents them from running at the noise-causing lowest voltage. Some folks on the Apple discussion boards said that OEM's who "fix" the noise do so by installing a daemon (or whatever the Windows equivalent is) that occupies enough CPU time to prevent this low-voltage deep sleep. There are similar fixes floating around for MBPs.
my mbp failed completely after just 7 days use. i've had it back just two weeks and the left hand usb port has now failed (burnt out) after my ipod nano was plugged into it for just one hour. i almost burnt my hand touching the right speaker.
i did angle pretty had for a replacement but apparently the policy is that a machine has to have 3 major repairs before they'll replace it.
in my mind they should be recalling all mbp's and replacing the lot.
this is my first mac and unless it comes back perfect and stays perfect it will probably be my last.

seriously, if this isnt' an isolated incident apple has a serious problem here.
i need to test my machine for heat issues now
UGH i hate being an early adopter.
anyone know a good test?

Computers should not whine, even if they're too hot; even if that heat is caused by a defect.

Otherwise, I have no idea.
