MBP Heat Cause Discovered & Solution!

[Freyqq]

when you take out the battery, the CPU downclocks to 1 ghz. There's an apple support article about it. Basically..that's the reason. The comp is running at 1 ghz so it runs cooler.....

100 degrees celcius is exceptionally high and on the very limit of their operational threshold according to Intel specifications. The logic Board has automatic shut down fail safes whenever such a point is reached as to not damage the cpu, the board or any components surrounding it.

You paid for a laptop which a specific performance. You make sure that Apple gives you that performance in every single way. Your case in my opinion is simply not acceptable and should be given to Apple to solve immediately. Anything less from Apple would be unsatisfactory.

Good Luck.

Uhh he opened it up. Applied AS5. Pretty sure that is the warranty out the window already.

That one was discussed pretty thoroughly at the time of the original heat problem. Your warranty is intact by law unless the damage is caused by your incompetence.

Thanks for all of the replies. I did apply some AS5 but it didn't do any good. I took the MBP down to the Apple Store this morning and they determined that they're going to replace the logic board & heatsink & fans to try and eliminate the problem. I doubt they'll notice my AS5 job...if they do I'll play stupid.

As a side note, they're replacing it with a 2.6ghz logic board instead of the 2.4 that I paid for. Stupid Genius or does this add some credibility to new MBPs coming out?

Also, just in case I get some haters about me opening up the MBP...I'm A+ & Net+ certified and worked on PCs, Macs, Notebooks, etc at CompUSA for years...now I work for a hospital doing similar things. I probably did a better job than the Apple Techs will when they open it up---

Wow, nice one. I'd say that lends credence to the new models being imminent.

It's good that Apple are now realising that those sort of temps are too high. When I re-pasted mine, they were stonewalling with a sort of "Well, you must realise that these are high-performance machines..." kind of routine. That's why some of us felt the need to take ownership of the problem and sort it out for ourselves.

With some luck, I am going to be getting a loaner from work while I send mine back to Apple. I have one of the original 17" MBPs and I am out right fed up with the heat issues. I am going to keep sending it back until it works correctly.

I agree that it isn't acceptable. What I find even more unacceptable is that all the work on the machine can't be done at the Apple store. Which means I will be without my machine for god knows how long. I haven't sent this machine back yet since it is my primary machine. Its so annoying how Apple deals with fixing laptops.

I hate only having 1 machine ... I am currently stowing money away for a Mac Pro. Hopefully I can get it this summer

I don't expect Apple to have techs in every one of their stores capable of repairing a MBP...they're pretty tight inside, and most people capable of replacing parts in a PC tower probably don't understand the complexities of working on a notebook 100X more cramped...

with that said, I wish their turn around time was a bit faster---7-10 business days is excessive. I agree on the loaner thing. $300 for Applecare, it'd be nice to have 3 or 4 Macbooks floating around to give to customers when needed.

I am happy that they're repairing my MBP in store, and at least they're working with me and letting me keep it until the parts come in. The part I don't understand is why it takes so long to do the repair---two days to stick a logic board and heatsink in? I disassembled and reassembled the MBP in 15 minutes. It shouldn't be that hard.

Well, mostly good news.

They replaced my Battery, Logic Board, Heatsink and both fans. They upgraded my processor to the 2.6ghz model which is still a $250 upgrade at this point which is nice. The rep confirmed that they are unable to order 2.4ghz mobos, so it lends a lot of credence to the imminent MBP upgrade.

The MBP still gets hot---80c under load or so, but that's a *HUGE* improvement over the 105c+ temps I was getting. It idles a little bit higher than it did (38c-42c) , but I imagine is has everything to do with the 2.6 in it as opposed to the 2.4. Everything is running well so for now I'm happy. We'll see how it goes in the future.
