2008 Macpro random shutdowns

I have a Mac Pro 2008 and it was the best computer ever.
Lately about 2 months ago it started to randomly shutdown.
The computer would crash with no indication, the screen goes
to black and after about 10 seconds, the fan would run at full speed.
All the while the power never cuts off.
what is going on ?
any experience ?
Help is much appreciated as I can't get any work going on at this time.

Start by cleaning out all the accumulated dust.
Do a smc and pram reset.
Boot from your recovery partition and repair/verify your drives (not repair permissions).
You might want to add a temperature monitor like iStat Pro, iStat Menus, Temperature Monitor, Hardware Monitor, etc. Maybe somthing is overheating.
Consider reseating your video card and dimms.

I have removed avast security and repaired disc permissions .Also carried ot AHT
Im in a panic now as well as my machine !

So, is Avast still showing up in the crash logs?
Have you blown the dust out lately?
Get Temperature Monitor to see if it's heat related...
http://www.macupdate.com/info.php/id/12381/temperature-monitor
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
/private/var/run/StartupItems
/Library/StartupItems
/System/Library/StartupItems
/System/Library/LaunchDaemons
/Library/LaunchDaemons
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
http://support.apple.com/kb/PH7029
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free Disk space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab of Activity Monitor, are there a lot of Pageouts?

To Everyone with Random Shutdowns! (Solved! REALLY!)

Hey all,
I had posted about a week back about my Macbook (Core duo white, late 2006), it was having the same symptoms as some of the others with the known random shutdown syndrome (RSS). Like many others I had thought it was the end of my macbook and the logicboard needed replacing because that is what the 'genius' people do, but I was still wondering what would cause it. It would randomly shut off! (or so I thought) I'd be typing in Safari, watching a youtube video, and even playing games, it would just shut off and I could hear the hard drive spin down. I'd restart and it would do it again sometimes right away, sometimes hours later.
This got me to thinking (like others have said) that it must be an issue with over heating. To test my theory I backed up my HD, and tried to reinstall Snow Leopard after zeroing the HD (as a fresh install). During the install process the Macbook's fan started to get loud and then it happened, it died again! So, this proved to me that it is NOT a software/OS issue at all, which means the said efforts in other posts of changing screen saver and energy saver settings had nothing to do with the cause! Aha moment!
I thought to myself... something is making it shutdown, obviously, and has to do with too much heat as the fan was going crazy even while reinstalling the OS. After reading many posts on different support forums I came accross the possibility that it could be the heatsink and/or sensor that is attached to it. I also found out that this "RSS" only applies to the non-unibody, core duo, and core 2 duo macbooks... you know what that means?
These models are the only ones with the shared memory and GPU on the same heatsink! GAH! A possible solution presents itself? To make a long post even longer... I removed the keyboard, carefully unscrewed the heatsink and fan and what did I see? Cracked and dried out thermal paste on the CPU AND GPU, they are both under the same heatsink after all, this was bad, really bad.
Luckily I had some Arctic Silver thermal paste in a tube from years ago when I upgraded my PowerMac CPU. Using some rubbing alcohol and a soft cloth I removed the crud on the heatsink, processor, and GPU (I might add that there was way too much paste on there in the first place). I waited an extra few minutes to make sure the alcohol evaporated, and then I applied a small (dime sized) amount of thermal past directly onto the two chips, I aligned the heatsink carefully and gave it a very small gentle push down onto the chips, reattached the sensor wire to the mainboard, and screwed the heatsink back in.
After putting the keyboard back on and making sure all screws were in... I immediately turned on the laptop and reinstalled the OS. The OS install took approximately 10 mintues! (crazy!) The last time I did that it took over 30 mins to install! I was stunned!
After the OS installed I let the computer idle and shut down, I let it sit for about an hour to allow the paste to contract as it cooled. After starting up again I immediately downloaded Temperature Monitor and installed it (I did have it running when my mac had RSS by the way), here are the results to prove my theory:
My Macbook with RSS:
CPU1 and CPU2 Idle temp - 114 degrees (F)
Heatsink temp - 128 degrees (F)
Approximate over heating temp - 184 degrees (F) (causing the heatsink sensor to shutdown the laptop)
My Macbook with new high quality thermal paste:
Idle temp of CPU1, CPU2, and GPU - 77 degrees (F)
Heatsink temp - 84 degrees (F)
Running temp with adobe CS4, youtube, and typing this message - 103 degrees (F)
Pretty amazing if you ask me!
Before I applied the thermal paste my Macbook took at least a minute to start up with a fresh OS install, now it only takes about 15 seconds! I have not heard the fan spin up and go crazy since! And I can't even explain to you how much fast it is now!
This does prove that Random shutdown syndrome (RSS) is caused ONLY by your GPU over heating due to old thermal paste between the chips and heatsink! A design flaw by Apple? probably not because thermal paste will crack and dry over time.
This also proves that energy conversion to data in the chips can decrease because of over heating, causing the computer performance to dramatically drop!
So before you take your out-of-warranty macbook to Apple or a repair shop, see what your internal temp readings are and try to replicate the problem with over heating your CPU/GPU! This was a 10 minute fix! I am still amazed at how much faster everything is, and haven't had a random shutdown since! I hope this helps alot of people that think they are out of luck and have to pay to get it fixed!

I too have this problem as well and it has been getting worse lately, I don't know what to do anymore. Here is a little info about my macbookPro. I have the late 2008 unibody model, i bought it in late 2009 Refurbished from Apple. Recently my mac has been turning off out of nowhere. I may be doing something and all of a sudden it just shuts off, it usually happens faster when i start to open up more programs like Photoshop or Final Cut Pro. My mac is out of warranty now and i dont know how much apple is going to charge me to fix it. i mean they want 50 bucks just to talk to them on the phone (ridiculous if you ask me)!.

MacPro randomly wakes

I have a late 2008 model MacPro 2.8 octo-core running the latest version of OSX.
I've unplugged all devices, turned off wifi and bluetooth and in the last 8 days my MacPro randomly turns on by itself during the night and during the day. I come home to blasting fans.
I'm not sure what to do or where to look in a log to find out what is stirring it to wake.

Macbook problems, hard drive crash, random shutdown, freezes

I bought my macbook used a few months ago, and it worked flawlessly until about 3 weeks ago. The system started freezing and not booting (getting folder icon instead of apple at startup). I ran drive setup and tried to repair the drive, but this did not fix the problem. DiskWarrior also could not fix it. I pulled the drive and installed a new hard drive, as I wanted a larger capacity anyways. All my problems appeared fixed for about two weeks, then similar problems began occurring. I backed up all the files I needed to an external firewire drive and attempted to reformat the new internal drive. Drive Setup says it can not reformat the drive - can't mount it and if it does, the drive disappears while in the process of formatting. I pulled the new drive and am having it replaced under warranty. I am using the firewire drive to run my computer, and this seemed to work fine for a day or two until the computer just started shutting down with no warning. Everything goes black, including the little light on the front of the computer. I have to hold down the power button for 10 seconds before it lets me start the computer back up. I had read this may be a memory issue, so I ran memtest and it says the memory is fine (I need to do it in single user mode still, however). I also tried pulling both sticks of ram. They are both 1GB crucial memory. I put each stick in by itself and tried it in both slots and was able to reproduce the shutdown issue with any ram configuration of either stick.
After all this, I realized the firewire drive was only running 10.5, so I updated all the software through software update, and it is now running 10.5.2. It seems to be working better as I have not experienced a random shutdown yet, but I'm anticipating it may start back up soon. Today, however I experienced a different problem - the screen froze on me and the only way to get anything to happen was to force a shutdown with them power button. It's restarted and seems to be working fine again for now.
I've run some logs and here's some things I've found:
When the latest freeze happened, I got this repeated over 100 times:
Apr 29 11:04:31 jon-turners-macbook quicklookd[536]: CGContextClosePath: no current point.
I've also seen this:
Apr 29 11:18:19 jon-turners-macbook kernel[0]: Previous Shutdown Cause: 3
Apr 29 11:18:19 jon-turners-macbook kernel[0]: GFX0: family specific matching fails
Apr 25 19:19:50 localhost kernel[0]: hi mem tramps at 0xffe00000
Should there be anything else I can check? I would run Apple Hardware Utilities, but I don't have the original disks, just the Leopard installer. I have Disk Warrior, but it seems strange this would happen with multiple systems and drives. I'd like to get Techtool Pro, but haven't had the money/time to order it yet.

Thanks for the replies!
Yeah, I think it's the HDD. I was just worried that the RAM was bad and corrupted the HDD or something, but given the symptoms I think you guys are right. Ordered a 7200RPM 320GB HDD off Amazon Prime...will be here tomorrow
I'll post how it goes after I finish installing it. I'm backing up as I type.
I wonder if I can fix the ir port and the sleep indicator light when I install the hard-drive. The sleep indicator light never turns off. It stays on as long as my computer is on, only turns off when I shut it down.

K9N Platinum: CPU upgrade = Random shutdowns..

I just installed a new AMD Athlon 64 X2 3800+ EE in my MSI K9N Platinum motherboard (MS-7250 v1.0, the 070 model according to the box). I had updated the BIOS to version 1.7 before installing the CPU. Anyhow, I got the CPU installed and it seemed to be running fine. Until I started playing my games. Upon playing fifteen (!!!) minutes of Day of Defeat, the system completely turned off. COMPLETELY. No error messages. I check core temp's log to make sure the CPU wasnt overheating; it wasnt. The max temp was 38C on one of the cores. Just to make sure the CPU wasnt the problem, I ran two instances of prime95 for 5 hours and there were no calculation errors whatsoever. I also ran 3-4 loops of SuperPi, using the 32M test. No errors.
I have come to the conclusion that it must be the motherboard, and possibly it does not like the CPU. Or else it is having the same random shutdown problems as many other K9N Platinum/Ultra boards are experiencing. From what i have read, this issue only relates to boards that are 040, 050, or 060 models. I have a 070 model, and I AM GETTING THIS PROBLEM!!
Help!!!

Any ideas?

well, i know that ACPI has to do with power saving features.
http://en.wikipedia.org/wiki/ACPI
and HPET also has something to do with CPUs
http://en.wikipedia.org/wiki/HPET
and MCP55 is the nortbridge.
so i suppose i can conclude that it protects from overvoltage or promotes more power-saving? i dunno i really dont care as long as my PC works now,

White Macbook 2006 random shutdown solved removed cpu heatsink and more

I picked up a cheap macbook from a secondhand retailer for $300 and it regularly shutdown, froze, restarted as well as the grey kernel panic screen completely random no real pattern. I set about trying to solve the problem swapping ram and hard drive with my identical 2006 macbook (which I had similar problems with last year, fixed that one with a new battery connector cable). The ram and hard drive made no difference so I downloaded istat menus to see if any combination of cpu voltage, current and temperature were causing the random shutdowns. It seemed when the temperature reached certain values the computer would shutdown or freeze(around 30 to 50 degrees). I'd read on other forums about faulty cpu temperature diodes so I reapplied heatsink compound to the cpu heatsink and checked all the wiring for shorts but nothing seemed to solve the problem. I was ready to retire the computer and use it for spares for my other macbook when needed but I pulled the keyboard off one more time and tried something completely radical. This fix requires some forward planning and software installation but it has completely solved my Random shutdowns completely.
for instructions see my next post *Fix for random shutdowns white macbook*

Ok this is not for the non technical person but it is quite a simple process with the right instructions.
This first step is very important install the software coolbook($10) and fan control (Free)( not smc fan control). Set up coolbook to operate the cpu at the lowest speed and voltage for both power adapter and battery(1002MHz and .95Volts). Remove the keyboard to access the computer logic board (instructions can be found at iFixit). Remove the four screws and two connectors holding the heatsink to the logicboard and gently lift the heatsink out (very important that you leave the fan screwed in and connected). Close the computer back up if you wish to test just gently connect the keyboard and loosly sit the keyboard back in. Restart and reset the pram immediately. Let the computer boot up and then open system preferences and configure Fan Control to your liking. So far no random shutdowns for over a week (was getting many a day previously.

Macbook won't detect external display anymore - Random shutdown injury??

Hi,
my Macbook has the dreaded random shutdown thing happening, often it can't even get through the startup sequence. If I reset the PMU and PRAM and check the disk every week I can keep it running. Applecare are making not particularly helpful suggestions like "run it in safe mode" - hello people, random means it can take days to happen again... I use this computer for work so I need it at full capacity every day!!!
Anyway, enough angry ranting. The casualty of today's RS and subsequent PRAM PMU resetting is my external display (Viewsonic LCD). The macbook is no longer sending signals to it (display says "no signal"). When I ask the macbook to "detect displays" nothing happens. I have restarted the macbook several times and unplugged and replugged the display connection it doesn't help. Yes, I have the AC power cable plugged in on the Macbook (I know it doesn't like talking to the screen if I don't).
The display and macbook have always worked fine together in the past...
Does anyone have any suggestions on how to test for causes or fix this display related problem?

You don't mention ever having brought the problem to Apple's attention, or what resulted from your request for Apple's help with it. This isn't a universal or widespread problem. It may be a hardware fault in your own equipment that needs to be resolved with a repair, or it may be a software problem (corrupt file, incompatible software conflict, update needed, etc., etc.). You seem to think Apple should have fixed it for you without your lifting a finger, and you're eager to complain about Apple's lack of support. But you've offered nothing to indicate that Apple even knows you need support. You do have to ask for it. Have you done so?
We have no idea what steps you've taken to try to narrow down the possibilities, e.g., making sure the monitor is turned on; trying a different video cable as iVmichael has suggested; testing the monitor with the same cable on a different computer; testing a different monitor with the same cable and then with a diferent cable on your computer; substituting a different cable adapter, if you are using one; applying all applicable system software updates and then Repairing Permissions and Repairing Disk; starting in Safe Mode and seeing whether the monitor is recognized and activated then; seeing whether the monitor is detected in System Profiler; and so on. You may have done some of these things, but you haven't told us about them or about the results.

Can an early 2008 MacPro be reconfigured as an effective video server for 2 27" 2013 iMacs plus a New MACPRO (to be released) and how would be the best way to do it.

We are a small eiting studio with an early 2008 MacPro (maxed out on ram) with a 4 Port SATA card, 2 27" 2013 iMac's, and we will be purchasing a new MACPRO once they're released. We work with Final Cut X primarily and would like to create a server solution to share media assets between the computers as well as insure our media assets are protected. Ultimately we see us moving toward an LTO tape backup solution for projects and we currently use the Acera 8 slot 32tb Raid for media storage. We use .DMG's to organize projects and we've had success networking the MacPro to one of the 27" iMac's and we can effectively mount projects off of the RAID on to both computers as long as the .DMG for that project isn't mounted on both computers. However we can really only run background processing (like rendering or inputing video) we can't really edit as it appears even with a CAT6 capabled connecting the two still isn't enough to be able to edit.
Ideally when the new macpro comes out we would like to explore the ability of turning the 2008 MacPro into our server and buy an attached storage solution but I'm unsure if this will work, what we would need to do to make it work efficiently (read fast), and what my limitations might be. Is it as easy as installing a new PCI 4port 1gigE card in the back and connecting our 2 27" Imacs and the to be purchased new MACPRO to that and insalling OS X Server?
Most of our projects are recurring and ongoing and require us to share our extensive library of live performances as well as insure its availibilty all the time without having to install the RAID set associated with those projects. We have about 80tb's of video we'd like to keep accessible.
Any help is appreciated and I would be glad to fill in any blanks if I left any.
Lastly, I might add that I'm not a fan of onebox solutions from the vendors, I believe that Apple has the products I need to do what I'm talking about and most 3rd party one-box solutions end up out-moded with in years of purchase.
Thanks,

Gigabit Ethernet can be limiting for large file transfers, which usually segues into either 10 GbE NICs and/or (less desirably) link aggregation and/or an Xsan configuration with Fibre Channel SAN storage, if you really needed the I/O speed and scale.
If you're serving large volumes of data and it's the the server-to-host Gigabit Ethernet link that is the limit (as differentiated from the RAID array or related I/O link as the bottleneck), then you're left to either or both 10 GbE NICs and FC HBAs, whether via Thunderbolt HBA adapter or via FC HBA in a PCIe slot. (Thunderbolt is not an option on any current Mac Pro or Mac Pro Server I'm aware of. That'd be PCIe. Conversely, recent iMac systems have Thunderbolt and no PCIe. And there's no Thunderbolt to 10 GbE NIC listed by Apple.)
Discussions of the new Mac Pro are premature, beyond the information Apple has posted. (But I'd probably also wait a month or three after release of any new hardware and software, in any event.)

Random Shutdown Because of Heat Sensors?

I bought my white MacBook in mid-May (week 19 production) and it worked fine with the exception of a whine when I did not have the iSight Cam on, the occasional mooing after using the computer heavily then using the CPU lightly for a while, and the discoloration. If you ask me it wasn't that much of a set back because this computer was fast and reliable... or so I had thought!
All of a sudden about a week ago, after I had the discoloration fixed, thanks to AppleCare (which only took 5 days), my computer shut down randomly in the middle of light usage...
At first I had thought that my external hard drive was the problem and I was very upset that this had happened. I tried to reboot my computer, but all that would happen was the usual DVD drive start up sound and then it would turn off again. I tried about 5 times to restart it with no luck, so I walked away. About 20 minutes later I was able to start it back up...
After not using my external hard drive for a day, it happened again, in the middle of normal internet browsing and listening to music it randomly shutdown. I thought that maybe it was an OS 10.4.7 issue, because I had not had any problems with x.6, so I erased and restarted from scratch, and once again, another MacDeath. Once again, I thought it to be my fault in my installation of 2Gb of RAM. I re-installed the custom 2x256 RAM that came with the computer ( and will remain in my hands forever, because you can't even pay someone to take away a stick of 256Mb RAM these days) well after the old RAM was forcefully shoved back in, it died again! This is when I started to get mad...
I put up with the whinning, I put up with the heat, I put up with the discoloration (for a while), but now this? WHY!
Over the next week it happened almost daily and sometimes when I would turn on my computer after it being off for at least 5 hours, it would load my home screen and after about a minute I would hear the fan come on for a few seconds, and then it would die again. I noticed that most times that my MacBook would shutdown unexpectedly, the fan had just turned on for a few seconds or I was playing a game and the fan was already on...
So today I called AppleCare and I had to wait about 30 minutes before I talked to someone... (When I called last time about discoloration, the wait was about 5 minutes) So either there are more and more angry customers calling, or Apple is firing employees to increase their stock value...?
When I finally got through the man told me that it was most likely not the Logic Board, but instead FAULTY HEAT SENSORS and/or FAULTY HEAT SINK APPLICATION. I won't lie I have seen Core Duo Temp show readings as high as 91 C (about 196 degrees F). I knew that this things got hot, but not so hot as to start a fire if left on too long....
So I am getting a box from DHL tomorrow (woohoo) MacB. and I get to part ways again, but this time, from reading many threads, I assume our time apart will be much longer approaching around 2 WEEKS!!!
All I hope is that AppleCare will fix the heat sensors that are supposed to shutdown the computer when it gets overheated.... I have to go to school in about a month and I will not have time to deal with these kinds of issues! I really like the MacBook and all of it's features, but I did not sign up to get a MacDieOnMeBook!

As of yet i'm not exactly sure about the heatsink problem, although a few in here have reported machines that work well after having this part replaced, while others who only had the MLB replaced reported a recurrence of the problem.
as for the volume indicator, i noticed that mine did that too, but it was in fact muted whether or not the tool bar indicated it. i dismissed this as a small quirk, similar to when my volume indicator didnt change as i pressed the volume buttons on my old laptop. but so long as there was an acknowledging "squirt" noise on the computer indicating change of volume, that shouldnt be a problem.
good luck withyour MB

Random shutdown then fixed?

well like alot of other users i got the random shutdown on my macbook the other night. i've been a long time windows user and finally got around to getting myself one of these nice new macbooks just last friday. (my pervious mac being a powerbook 190cs about 9yrs ago now) anyways all was going well till it randomly shut down on me. so i unplugged it and turned it on again this time it took alot less time to just shut itself down without my input. after this it wouldn't even make mac OS so i held the power button for 15 secs and it booted and didn't shut down for the rest of the night (except for when i reset it).
i had had boot camp installed and while i was in the city today i went into next byte and talked to the guy in there who said that some people had solved it with a software fix. i had a look through these forums and saw that bootcamp didn't seem to play a part in most cases of this happening.
i ended up deleting bootcamp off the hard drive as i was no longer using it after finding replacements for all bar VS 2005 and Access and was using them in parallels. after deleting bootcamp i haven't had a problem however in trying to work out what it was i noticed that instead of displaying the apple logo first up when i booted the machine it held the folder with ? on it for a minute. after getting rid of bootcamp this no longer happened.
i dunno how or why but it no longer seems to be randomly resetting and not turning on. i'm hoping that its fixed becuase i really don't wanna have to send it in to apple for some of the fixes other people have had to do.
anyways i just thought i'd post it incase it helps someone.

Anybody have any ideas?
I shut it down for a couple days. Just tried starting it up last night and it only made it to the login screen before it shut down again. This time it didn't try to turn back on.

Random Shutdown in 2010 for a 2006 Macbook

Hello-
I have a 2006 Macbook 1.83 GHz processor and I never had the whole random shutdown problem previously... it burned through batteries like nothing and I was about to install my third hard drive, but no random shutdown problems. Well, now I have it...
Anyway, it is out of warranty, obviously.
1) Will Apple still replace the heatsink, since it was defective even though I am out of warranty?
2) If not, does anyone know if by replacing the heatsink that should fix the problem?
Thanks

Sure Apple will replace the heat sync. At a price. I may be something else though. It might be full if dust after all these years. You could try putting a vacuum cleaner over the in vent and give it a good sucking. Worked for a friend of mine...

Problems with random shutdown after replacing a swollen battery

Hello all,
Perhaps one of you can help with this issue.
I'm using a Macbook Pro 17" mid-2007 model. A few months ago, the power disconnected from the machine when the battery had already run down and the machine did a hard shutdown. When I booted it back up there were serious problems with the display. Eventually it stopped working altogether. I took it for service and it was determined to by the NVIDIA graphics processor problem, so Apple replaced my motherboard.
When I got the machine back from servicing, there was a rattle in the right fan that gradually got worse. After a while the touchpad button stopped depressing in the center. I also experienced several random shutdowns while operating on battery power. I learned about the swelling battery issue with macbooks and ordered a replacement. By the time the replacement battery arrived my original battery was quite swollen. I'm concerned that the swelling battery may have warped the case a bit, leading to the fan noise.
I have now replaced the battery, but I'm still experiencing random shutdowns after 20+ minutes of use on battery power. I have done the RSS tests that were recommended in other forums and there doesn't seem to be any random shutdown problems when I'm plugged in -- only under battery power. My understanding is that a swelling battery can sometimes cause the battery to disengage from the electrical contacts on the MB, causing a sudden shutdown. I'm wondering why the problem is persisting now with a new battery? After one random shutdown, I tried to power up again using the battery, while pushing the battery into place at various angles, but I couldn't find any angle that would give power to the machine. The fan noise is also still present.
Can anyone offer an explanation or advise on any methods to overcome these random shutdowns? I have checked the console and the machine isn't registering any error when it shuts down, although when it restarts it says "DirectoryService[35] Improper shutdown detected"

Yep, it is video (or: or audio for video) so unless you're sure you need it (because you work or will work with the DVC Pro HD video/audio codec), you can remove the plug from its' folder and put it in your documents folder (don't trash it, I have no idea if it is necessary for non-DVC Pro HD users to have it installed too).
The WWW is littered with posts from people encountering bugs and crashreports with DVCPROHDAudio.plugin as the main suspect. Most of those posts seem to be from video people rather than audio folks.
http://www.google.nl/search?q=DVCPROHDAudio.plugin&ie=utf-8&oe=utf-8&aq=t&rls=or g.mozilla:en-US:official&client=firefox-a
But, if you get crashes and you see this one mentioned in the report, disable it, restart, and see if the problem's gone.

Not so random shutdowns...

Hi,
My Macbook is just over a year old now still under applecare, I had random shutdowns before and did the firmware update which fixed it. Yesterday, I had the +please hold down the power button...+ message and so did thinking little of it, after all it is not uncommon to have to do it once in a while. Since then though it has been intermittently restarting all on its own and occasionally throwing up the +please hold power...+ message. Interesting to note is the optical drive noise when it restarts itself. I know how it should sound, the kind of mechanical movement sound that happens when you restart normally (or launch parallels and windows grabs hold of your drive). However, occasionally on these restarts it pauses during this sound several times making the same noise but stuttering through it... Strange!
It seems that I can often make it restart or throw up the power button message by just lifting up the front of the computer, as you would if you were turning it around or something. This leads me to believe it's a hardware fault... Looking under the battery compartment the two outside screws that are on the battery connection side were loose and nearly falling out so I tightened those back up, still the problem persists.
After the last restart message I copied this error report, I have no idea what to look for, just wondering if anyone can see anything helpful?

I have tried a PMU reset, PRAM reset and whatever it is that happens when you hold the power button when you turn it on to make it beeeeeeep... The issue happens with or without the power cable attached.
Unless anyone can suggest anything here I'll be taking it to the repair centre...
Thanks for reading!

Ok, this is not an answer but it may help you a little: have you checked your logs? It may be an indication of what has happened there. If you don't know the drill: go to console under applications/utilities, select logs, and go there to /library/logs/panic.log. Some information may appear there, for instance if there is some consistent cause like one of your processors, some specific fault.
Not much, I know, but at least you may glean something out of it.
