Q: MacBook Pro 2011 17" hard freeze

Yes, optical means the cd-rom controller. Are you experiencing any freezing problems?

Hi, I have a diferent problem.. (sorry for my bad english..)  My macbook pro early 2011 i7 17" sometimes restarts on its own suddenly (one time in a month maybe). I already reset the SMC and PRAM and NVRAM but the problem continuous. I´m checking the temperature and fans with isat pro and some times is hi when export a movie or render something (nearly 90ºC) but the fans are working well.. any suggestions? Thanks

@ JavaX

Yes, read my post a few posts above.

the freeze may not related to your second and third points, for the second point, I have try the Apple stock HDD, a seagate Hybird drive and SSDs, all suffered from the problem.

For the third point, the MBP may freeze even the temperature under 60 degree C. It

According to Apple 60c is to HOT.

Well, I am not sure what to say, but my issue has disappeared somehow... I am a little paranoid that it might return... It has been three days of heavy abuse. I have been trying real hard to duplicate the issue again... I have the older chipset, and it was exhibiting the behavior.... I had a genius appointment to swap out the computer, but cancelled it because it seems to be running flawlessly now.  I sure hope the issue doesn't come back as soon as the 14 day return policy is up... Errrrg... has this issue been known to hide for a while and then come back?  Thanks...

jpcwa, seems that you are not owning 2011 MBP

According to Apple, everything under 100 degree C is normal! (It's true for 2nd generation i7, and every i7 in the PC world!)

Below is the explaination why 100 degree C is normal

According to Intel, i7 will have a cut off temperature at 100 degree C.

When the CPU need more processing power, it will run at a higher frequency (known as Turbo Boost). Then the CPU temperature will increase until 100 degree C, then the CPU start to slow down (running at a frequency that won't further increase the temperature.)

Most likely, the CPU will run at about 120-130% of it's frequency and the temperature should be arround 98 degree C until the process finished. Once the CPU back to idle, the temperature back to about 40 degree C

According to the Everything Mac Manual p. 73.

Notice: Failure to follow these handling instructions could result in damage to your MacBook pro or other property.

Operating Environment Operating your MacBook Pro outside these ranges may affect performance:

• Operating temperature: 50 to 95c (10c to 35c)
• Storage temperature:  -4c to 113f (-20c to 45c)
• Relative humidity: 5% to 90% (noncondensing)
• Operating altitude: 0  to 10,000 feet (0 to 3048 meters)

Hey! we are talking about CPU temperature!

NOT Operating temperature!!!

You would like to use your laptop in room temperature of 60 degree C?

@jpcwa

You said that the freezes may be caused by eletrical issues. I remembered that my desktop PC started freezing years ago, the same way the new MBPs are freezing. I tried to find out what was causing the freeze and I discovered after a lot of headache that the problem was caused by my Power suply unit, it wasn't delivering enough voltage to the hardware. I changed the PSU and problem solved. In the MBPs case, i think the new hardware may require a redesigned logic board which could deliver the correct voltage to its components.

*rolls eyes* cpu temps are a part of overall operating tempratures.

Not enough power, that would defenitly fall into the category of electrical problems. And btw, heat problems can be caused by electrical problems like that. NOT enough power and the fans will run slower as there a lack of power to run them at higher speeds which require more amperage.

jpcwa, you just keep giving us joy

Operating temperature means the temperature requirement of your room/place that you can operate your computer without problem

... well... never mind...    A funny guy that keep misunderstood others...

anyway, after an hour long phone conversation, Apple agree to replace my logic board with a latest reversion.

see if the latest built fix the problem.

Operating temperatures have nothing to do with the room or room temps.

"An operating temperature is the temperature at which an electrical or mechanical device operates. "

Hi everyone,

I wrote up on page 99 (https://discussions.apple.com/thread/2768351?start=1470&tstart=0) that my brand new top end 2011 MBP 15" is freezing and white screening me.

I'm currently stuck on a boat in the Pacific, not back in NZ till September with a Mac with a white screen. It shows the grey apple on start up, then the whirly wheel, then just a white screen, then the fan starts winding up. This is happening every time I start it up.

Unfortunately I am new to Macs, having wanted to have one for years, and now it's broken, and I have no idea what to do. I have very limited web access and no manuals with me!! All I can do to turn it off is hold down the power button till it powers down. I know this sounds pretty dumb, but can anyone give me any ideas of how I can maybe get a visible screen again - or do I just put it in a box for 2 months?

Please help!

James
