display anomalies

for every members of this club , at least 1100 users sign the petition, and no reaction from Apple.

here, with 25 to 27° celsius inside, it become difficult to be on a 2000 $'s MBP:

- Fans are running all day at 5000 rpm, I run my MBP always without the battery, that mean it run at 1 Ghz, and not 1.83. This save 10 c°

- I have a notebook cooler under the MBP, running to the max all day long.This save 3 to 5 C°, but it's important because it save it more for the GPU unit than for the CPU.

- No internal superdrive, as it is dead, so I totally remove it, it gave me some °, especially when I try to put the battery on . Unfortunately, it seem to be only for some minutes, I believe that it is only because residual heat is not stored in the mettalic mass of the superdrive 😟

- I"m still on 10.4.11, which is the less consumming ressources Os for now. I have done some boot devices until 10.6.7, and still have them for software reason, and every update is less optimised and more ressource consuming

- 10.6.3 seem to be the best, BUT after 10.4.11, AND it still give me 5 to 8 ° celsius more, when iddle 😟

Since a year, my MBP now crashes when GPU is 44°, which is not a so bad evolution, when looking at other posts here. It show artifacts at 43 °

To be honest, I don't WANT to use my MBP with bootcamp and Window XP, so I will wait until I can't do anything else , the same for Linux, even if it may be a better solution. 😉

The only thing that I have not done until now is changing the thermal grease . I will do it in 15 days, with Noctua which seem a little better than artic silver.

But I strongly believe that we can make our MBP live a lot more by just cooling them to the max : I mean : I want my MBP running at full capacity, and the gpu not going further than 30 or 35 ° celsius.

So may be, it's time to look for alternative way to cool them down. I have tried a ice container, just in front of the air entrance, I gain some °, but i'm afraid of humidity dangers.

I would like to see a "refrigeration coolbook", some device which could gave me 0° under my MBP and under the air entrance...

On the net, I saw years ago a device build by a geek to just cool his beer, with Pc Parts, unfortunately, I can't find anuymore the video : I would like to have the same to cool my MBP.

I really think that it is our only hope to use our computer in the next 2 years or more : cool it to the unimaginable way.

I don't know for you, but for me, my MBP is no more a portable, as it crash always, when using the battery, because it run at the full speed, and even fans set to 5500 rpm, it crash with any graphical software in 5 minutes, when it startup from cold state, or in 1 min, when it reboot.

So, people in the same case can do anything, including holes in the bottom case, under the GPU.

It worth the 2000 $ price, to get our computer run some years more, as Apple is deaf to our complaints.

Last: on winter, I live with 10 to 11°c in my room : that's the only season where I can have my battery on, do some 3D graphics, play some games. So I strongly believe that cooling a lot is the only solution for us.

(as always, sorry for my bad english)

Hi PatBe,

I wonder if under-volting might be worth looking into for you?

Long story short - MBP 1,1 with the accursed Radeon chip which has the same video problems most everyone else here has reported. I made an appointment today at the Genius Bar of the nesrest Apple store (sixty miles away). Perhaps the only way that my experience could have been worse is if the Genius had spat in my face:

--When I explained the problem, the Genius proceeded to pull out a portable HD to run some diagnostics, only it was labelled for the NVIDIA chipset. It took me *three* tries to explain to him that my chipset was ATI, not NVIDIA.

--Apple is not admitting we have a problem. I even went so far as to point my Genius to this thread and two others here on Apple's forum, plus the countless others on other tech forums. No dice. They'll admit the problem they had with NVIDIA (probably because NVIDIA themselves admitted they had a bad batch), but not with ATI, even though the problems are reported to be indentical.

--I was told my only option, short of buying a whole new computer (and by golly would they be willing to help me ith that) was to send it in for repair, through them. I asked how they would repair it; I was told they would most likely replace the motherboard. I asked them why I would want spend a not insignificant amount of money to replace a part that is dying with one that is guaranteed to die at a random point in the future. A blank look was what I received in response. And forget about a warranty on the repair work (although to be fair, there might be one and the Genius just neglected to tell me).

--Since I didn't feel like this guy was being overly helpful, I asked to speak with a manager. I was told in no uncertain terms that *no, I could not*. At no point during any of this was I rude, or angry, or even raised my voice. I've worked in retail before, and I know quite well that being mad or impolite is the last way to get customer issues resolved.

If this is how Apple treats its most loyal customers (in nearly 30 years, I've never owned a computer that wasn't a Mac), then it's time I start offering my custom to someone else.

Hi Tjk.

thanks for yout hints, I tried them today . Unfortunately, coolbook don't work, it seem on my rev 1.1 macbook pro core duo, 1.83 ghz.

and the same for xnu-speedstep .😢

I have tried them on any OS, from 10.4.5 to 10.6.7 with no success.😢

Too bad, because it was a good solution, on paper, and according to others forums, a nice one to get more speed with less heat.

If anyone here with a rev 1.1 core duo have been able to make coolbook run efficiently, please, say it

for xnu-speedstep, driver don't want to load, in terminal. It seem that it is because my computer don't allow managing speed and volts.

Grrrrr....

But i'm sure your hint could help others, with core 2 duo, for ex.

For Inkraven: I still have 8 Macintosh at home. the only intel one is the only one with such problems, and for sure, I will never again buy a rev 1.1. If I had to change my computer, even if I gave 20 years of my life to support Apple, even when it was in the dark side (1996, saved by Bill Gates ) I would really reconsider to have a computer and OS from Apple. May Be the OS is enough... What made me mad is to see people using non apple computer with os X, and having not this dead end problem !

I'm really sad to see that this very well knowed failure, which impact 2 or 3 thousands of customers, is not taken in view by Apple, who have 73 billions of $ cash. it's not a cosmetic failure, it's a death one. Apple have made a lot to replace cover or case for painting troubles.... it cost a lot, too...

Here, it's the motherboard which is dying !!! I don't care about all the painting gone on my keyboard! I care about being able to use an expensive computer with Apple trademark of quality !

And I can't do it now.

Come on , moderator, please, bring this dicussion up in your hierarchy !,please ! 😐 (I mean, talk about it)

hi fellowa this is zaeem::

i have same problem with my macbook pro 2,2 ati raedon x1600 graphic card......the problem arise when i upgraded to sneak peak(mac os x lion)....i am trying a lot to repair my mac through software changes....but i now going to beleive its an hardware problem.so i have to open my mac....any one help me out to open macbook pro 2006...or any picture of inner circuitry.....

thanxxxxxxx

hi everyone: first, I have managed to run coolbook, so foreget my previous answer. The answer was in some minuts shut down, as any reboot don't change anything. After a night , coolbook was effective !

Now, I can have more speed for the quite same heat, but, of course it is still crashing, as I was running with the lowest set since 2 years.

But It crashes a lot less with more speed !. It worth the 10 euro price. to be honest: it crashes the same, but I run my computer faster...

Thanks again, TJk, for pointing it !

#Zaeem: Ifixit is / will be your source, and in second, Google. But iFixit are really THE macintosh repair N° 1 in the world, to give you blueprint, plans, and anything that Apple don't want to give you. Sorry, modo, but it's nthe truth....

thanx buddy......

i am unable to start the apple hardware test ,i've done anything ,holding d at start up with inserted installation disk,also with holding c........

apple logo appear and after some time with spinning wheel it stuck with white screen....

please help me out....what to do???

You're welcome. Why not slow it down and see if that reduces heat/crashes?

Guys, i strongly recommend to clean out the fans and the exhaust grills. I just opened mine up on Friday after about 1 year of cleaning the, at the time i though it was clean. Well to my suprise the grills on the exhaust ports were clogged with so much dust there was no way for air to escape. Now i know these laptops can clog up fast. But I also reaplied the thermal paste that I had put on a year ago (did remove the old one, just put more on since the old paste was still good), I didnt hold back, i made sure the cpu, gpu and chipset received a thorough amount of paste. Now it runs so cool with the fans fully up. I literally feel no heat on my laptop except if im playing games. This has reduced my temps so much, i went from an average of 60 C to 32 C on my cpu.

heres the teardown guide from ifixit

Virgilaug1,

I'm glad that worked for you, but to others who may apply thermal paste, please read directions. CPU and heat sink want to be metal to metal as much as possible. The intent of using thermal paste is to fill microscopic "holes" between the two metal surfaces, so there are not air gaps and as much contact as possible. Metal to metal is much preferred over metal to thermal paste to metal. Too much thermal paste can actually act as an insulator between processor and heat sink. Usually, an amount somewhere between the size of a half a pea and a piece of rice is sufficient. When you see paste oozing out the sides of the processor and heat sink contact surfaces, it's too much; luckily, sometimes it works ok because enough has squeezed out, but that may require a lot of pressure, and you don't want to go gorilla on it.

I agree with Tjk, the way you apply thermal paste, virgillaug1, seem dangerous for me (But I'have never done it for now.)

The more thermal paste you have, the less it works, reading from forums.

@tjk : I can't use coolbook to reduce heat, as I was using the lowest heat, when taking off the battery (1002 mhz, 0.9500v)

the good thing is to be able to run it faster, for only a little more heat, and a lot of less heat than in the Apple default choice.

But to cool it better, coolbook is useless in my case as I'm running for 2 years at the lowest mhz and tension possible. What is very nice is that I can set up the fastest ghz, with less current, so less heat. I will wait this winter, but it is already a nice trick: xbench gave me better speed results, for the same ° or so, if I clock the Mbp to 1670 mhz with 0.9875 v.It runs for now. My problem is to get ALWAYS the GPU always under 43 ° For that, except new thermal grease, my option will be very alternative, and it's difficult to choose, because my MBP is my whole life, and I can't afford a new one...

I think there is a good chance I might have found a solution. I read A LOT about this issue, I tried many, many things. In the end, I thought, preforming a clean install of 10.6 and booting in safe mode after the install finished to make sure the GPU was never exposed to the driver was a solution. And it was in the sense that after doing so, I never had issues again. Other have done the same with great sucess it seems. But I was not content with not being able to take screen shots, a broken Preview app and lack of any video card acceleration, so I figured what the heck - lets update to 10.6.8 which should have the updated graphics drivers.

So here is what I did (copied from my post on a Facebook page with more details).

1: Remove power and battery, remove upper cover and disconnect the PRAM battery for 30 minutes. I did this because if it is indeed just a software issue, why would I have bad graphics before the Apple logo even appears. An SMC reset would not clear the issue. But pulling the PRAM battery sure did during other attempts to narrow the issue. Its as if the PRAM got corruped making the issue worse.

2: Hook PRAM battery back up, reinstall cover, battery and power.

3: Boot from Snow Leopard CD. Do NOT boot from the drive, if you do, start over.

6: Format the drive and install a clean copy of Snow Leopard.

7: CRITICAL - When the installation completes and it want to reboot from the drive, you MUST boot with extensions off by holding shift key. You should see a progress bar when doing this during boot, when you do you can let go of the shift key. The idea is that the system will never, ever be exposed to the ATI drivers. This was more or less a test to rule out drivers or hardware - I do think its a combo of both though.

8: If you did step 7 right, it will also not show an intro video common with a new install/new machine. Continue with setup instructions.
9: At this time the machine has NEVER been exposed to an ATI driver. I had actually installed iLife and Photoshop and did a few updates excluding system updates. I used the system for many hours taxing it and letting the heat levels climb.
10: Repair permissions.
11: Install 10.6.8 update.
12: Hopefully you can not enjoy your Mac!

I will add that after the clean install I installed SMC Fan Control and kept the fans running above 3k RPM. I tried to keep the GPU below 105 degrees F, since the screen artifacts always appeared about that time. The laptop, even with a different board, was pretty much unusable within minutes of any normal activity.

Since I did the above I have gotten the GPU well over 140 degrees and played several HD videos, played HomeWorld 2 for testing of the 3D and did other numerous things to tax the system. Being wary, I had been running the rans at full speed. But now I keep them at 3k at all times. I am hesitant to lower the fan speeds, but I have yet to see a single issue. Many reboots, everything updated. I checked and the driver version for the X1000 series is indeed newer with the 10.6.8 update.

In short, before this I had reset the SMC/PRAM many times. Ran the fans at full speed non-stop. Repaired permissions. Removed preferences and caches. Etc. I even removed the extension post-corruption but still had issues. I read at lot and tried it all. I FULLY expected that after installing 10.6.8 and NOT booting into safe mode (meaning the machine has now used an ATI extension) I would have the same issues come back. Sorta was not hoping to have to do this all over and reinstall software.

Anyway, this clean slate (clean right down the the PRAM) certainly worked for the MacBook 1,1 I am using now. Its been running over night just fine. Rebooted after some updates this morning. Still good.

Someone PLEASE try the steps here. I would love to see if this works for anyone else.

By the way, I will install SPORE tonight. Should be a pretty good test of the system and get the VRAM maxed out.

m,

Nice work. 😉 I'm sure it will help a lot of people. One comment to add though, for others' benefit; only the early MBPs have a PRAM batt, the rest have capacitors built in to the logic board. If you're unsure if yours has one, check at someplace like ifixit to see if they list one for sale or show a repair guide for getting to it.

Spore with settings set to high on most and no issues. If this holds up for a week then I think I can start trusting it and using it for real work.
