Anyone else with the new i7 MBP experiencing a hard freeze? No Grey Screen of Death, just freezing screen and input. Only remedy is to hold the power button to cycle the power.

It has frozen twice in the last week. Both times the machine was on battery power and certainly not under load - just light browsing, no gaming.

Just curious if this is going to be a longer term problem...

I am shocked at how watered down and slightly random this discussion has become. i'm offering some common sense:

# please do not post if your machine is not a 2010 model and/or does not use the nvidia 320/330 chips
# if a freeze/crash occurs in windows and not on osx, please wait for a software update. windows drivers are no priority at apple.
# if you run virtualisation software and experience freezes, stop it and check again. see point above.

i am pretty certain this is not a temperature related issue as I ran "yes > /dev/null" (100% cpu) in 4 separate terminals on a brand new i5/15" antiglare high-res at the apple store. the machine could have burned the table (400% cpu). it certainly burned my fingers when i touched underneath. no freeze, no crash. but i did see a flash of garbled graphics in a Flash applet I had left behind other windows...

if you report a freeze, please report your setting of automatic graphics switching. also if you run gfxcardstatus or any similar utilities. most certainly report if you have migrated an old system on top of your new mac.

last but not least. if you wish to remind everyone how much money you've paid, go to and share this valuable information there.

how can this topic be "answered"??? People are still having problems like crazy and there seems to be no clear way of making this "freeze" go away, officially. It seems that a fanboy just got upset with so many people trashing apple on this for not responding and could not handle his precious Apple being trashed. the only way this can be marked as answered is if people can fix this problem with the "solution" 99.9% of the time.

Seriously, people have spent over $1k on their machine and this thread in no way helps them fix the freeze problem.

Sigh. Got a new trolling motor did we?

None of the following is official in any capacity. I don't work for Apple, any related supplier, own stock or anything else. I'm a customer who just happens to know more than a little about the technologies and troubleshooting, thanks to a 20+ year career in the industry. That said, I'll try and be brief and use short words:

*This thread about the 2010 i5 and i7 MBP 15" and 17", and total system "freezing". Anything else is a distraction, start your own thread.*

"Freeze" is a generic term for when a system stops responding to input (keyboard, mouse, network) and sometimes the screen output stops or gets trashed.

Just as there are many causes and types of causes of something like an animal sneeze or a car backfire, so it is with system freezes.

After examining what happened with my own machine, and reading the reports of others here and elsewhere I'm "convinced beyond a reasonable doubt" that the "circumstantial evidence" supports my expert guess at what's happened. (Sorry, big words, but they've been on TV, so hopefully not beyond anyone's vocabulary.)

A relatively small number of systems have a defect that causes an unpredictable freeze. The type of freeze depends on what the system was doing at the time the defect showed itself.

The freeze doesn't show itself in any predictable way (several people here have tried, me included) and any number of parts could be the guilty party with the same effect. This is also why tests done at the factory may not have caught the problem components either. It's shown up with or without "gfxstatus" and other bits of software running, locked to Intel or Nvidia, and under 10.6.3 and 10.6.4, and with various patches applied or uninstalled. THAT all points to a hardware problem.

To compare: Big, expensive, server systems (like the ones that run banks, hospitals, or anything else where there's serious money, lives, or both at risk) have the extra capability to be able to tell that something's wrong if something like 1+1 suddenly =3, and the extra parts to correct errors. Another example: The shuttle has 5 computers that all check each other during liftoff. Consumer laptops, even high end one like the MBP don't do this as it would easily double the price and the type of weirdness required to cause this sort of problem in a "normal" system doesn't happen very often. Cases that go from "occasionally in a month" to "several times a day" and identical hardware and firmware versions between affected and unaffected systems suggest the underlying cause is a latent manufacturing defect somewhere that may be made worse by usually allowable changes in how one component is manufactured to the next (tolerances).

New graphics chips, new graphics switching mechanism, new other chips, etc. It would actually be more surprising to me if something like this didn't happen. It's the joys of buying the latest and greatest. It can be a LOT worse. Go Google "laptop fire" if you want to see.

If you're buying a MBP, buy with confidence as you chances of getting a unit with a problem appear to be very, very low, as the "bad batch" seems to have worked its way mostly out of the supply. If, like me, you were very unlucky, well, it siphons, but that's life. The number of affected systems don't need a recall, that's what a warranty is FOR.

If you think you have the issue, take the unit to an Apple store (make an appointment first, doh!) and explain that you're having an intermittent freezing problem that you can't make happen when you want to. Tell them that you've read of a small number of other people who have had similar problems, and that the fix seems to be a main logic board replacement. Point them to this thread even.

If you don't live within a convenient distance of an Apple store I presume you planned for that when you bought your system, right? That doesn't mean it doesn't siphon but it's also life.

All I ask is if you do get your unit's board replaced or even just tested, report it back here to confirm or disprove the educated guess above.

I think I failed on the brief part, but it IS a complicated problem. The above is AN answer, so it's ANSWERED. Oh, and some of us spent quite a lot more than US$1000 on our MBP's. No likes a whiner.

    I have had my Macbook pro for less than a week and had the same issue occur today. I ran the hardware test (short and long test) and no problems where reported with the hardware. Not sure what else to do.

    5 hard freezes and 1 Grey Screen of Death. There are 6 kernel panic log in the system console. This is a 15" Hi-rez Anti-glare model. It locked up once after I initially set it up out of the box and decided to erase and install clean.

    I have an appointment at the Genius bar tomorrow afternoon. I'll let you know what comes of it.

    In contrast, my MBP from last year has never locked up and is running the near exact application set.

    it freezes daily, comes back after 10-15 minutes.. disappointing..
  • Alessandro Vernet Level 1 Level 1
    @aozoren, are you saying that when you get a freeze, the OS comes back to life as if nothing had happened if you wait for 10-15 minutes?

  • Duk242 Level 2 Level 2
    I'm having the same issue too.

    It has happened 3 times in the last 3 weeks that I've had it.
    Temperature at the times was normal, last crash tonight the CPU was at 54degreesC (the coolest it ever goes while in use).
    I've got my normal set of applications open: iStat Menus, Adium, Firefox, X-Chat, Quicksilver, iTunes, NetNewsWire, None of these have caused issues in the past.

    Extra Devices attached: Mini DisplayPort to DVI Adapter to my 22" screen
    Keyboard and mouse are running via Synergy from another machine.
    Also running optical audio out.

    Here's a couple things I've noted when it crashes:
    * All applications will freeze and the mouse can still move for about 5-10 seconds. Then the mouse will freeze too (it freezes as a pointer arrow, nothing beach balls).
    * Most network connections are dropped. I lose my Synergy connection (mouse and keyboard) and iTunes (playing off a network drive) will stop too (it goes silent, not playing the same frame again and again).
    * The most peculiar thing though, one time I was chatting to someone with Skype, and the video froze, the mouse froze yet I could still talk to the other person. This indicates that everything else is still running, the network is still able to keep up a stream and even the audio is still going alright.

    Hopefully some of this information helps, I'll post if I work out something else.

    I am having this issue with my new 13" SSD. I just repaired permissions... will see if that works. Generally this happens if I leave my computer on overnight, and in the morning it will freeze. Hopefully repairing permissions does the trick.

    I have been having the same problem. The screen becomes unresponsive and I have to do a physical power off. The machine is not under heavy load at the time. One thing which has been present each time is flash applications in Chrome. But then, parallels has also always been loaded.

    What is bizarre is that iTunes will keep playing audio even after the machine flat lines??

    I had it happening every day or so, it is extremely annoying. I have moved over to Windows 7 on Bootcamp to see if I see still have any problems. I have had one blue screen so far, but I need more time to see if it is a recurring problem. At least this will give an indication as to whether it is a hardware of software problem.

    Will keep everyone posted, these mysterious problems are never the best to troubleshoot.
  • Janus Andersen Level 1 Level 1
    I have had the exact same problem with my MBP.

    First the system becomes totally unresponsive but mouse cursor will still move. Then the cursor freezes.

    Sometimes I regain control after 10-15 min ... sometimes not.

    I have had it happing under Win7 once as well.

    It usually happens when the computer is physically cold.

    I have no entries in the Console.

    has anyone tried the Automatic Exchange graphics modes to disabled.? for me it started mainly with graphic problems. eg. start of imovie, itunes, iphoto, photo booth.
  • Innovimax Level 1 Level 1
    I got the very same thing...2 years ago : it ends up by changing my motherboard (very recently) ; it was due to the graphical system becoming too hot and then freezing
  • socode Level 1 Level 1
    I've got this too on a new 17'' i7. Three times in 3 days - hardware test etc. is not showing any issue but the kernel log shows an NVDA graphics channel exception.

    Not under load or hot at the time.

    I Have had my i7 MacBook pro for one week and can't use it. I find it happens offten to the point where I can't trust it. Short PowerPoint presantions freezes up 300 people in attendence washington DC DOL sad . I had told a tec after a couple of days and he tried to tell me it was my mac office it happens just using mac iPhoto slideshow ? Pretty upset.

  • Artitron Level 1 Level 1
    @aozoren, Interesting that it comes back after 10-15 minutes... I will try to let it sit that long the next time. I have been packing around my Flip waiting to reproduce the issue and catch it on video.

    Along with others, I am not running a lot of apps: maybe even just Mail and Firefox when it happens.

    Additionally, the logs in Console do not seem to have anything useful within them that even notes the problem. There are no Kernel Panics logged with only one CrashReporter logged for the adb (Android Debug Bridge) which happened after the last freeze by a day. This machine is very new, so not much has really happened on it.
