Very upset at macbook random shutdown

does anyone have a solution to the random shutdowns that i have been having on my macbook? i will be working on it and it will just shut off. i am always scared that it will go dead and i will lose what i am working on. i am pretty mad because i have really liked apple products and always felt that they were better than pc's. but to pay $1500 on the computer, printer and apple care, im a little ticked to only have it about 3 months. help me please, i really appreciate all the people who reply to these messages.

They are a world-class company with
world-class support and have earned that over many
years. They will take care of you.
I really don't know whether to laugh or cry when reading your posting. Your reply hardly reflects reality in this particular case. My MacBook broke down in the last week of August and it has not been repaired and returned yet. They aren't even able to say when it will be repaired. People with RSD are being turned away at present, as the repair centers actually don't have the spare parts from Apple. This is not world-class in any way - it's a case of bad management, bad planning and bad logistics. I don't blame the poor person at the AppleCare doing the repair. However, persons higher up in the organisation have failed miserably and let down customers, company and colleagues!

Macbook Random shutdown osx 10.4.7

So i've been hesitating to update since the last problem with the security update that came out in the beginning of August crashed my macbook. and the recent one with the Fan i have not updated also, but it started yesterday where i'm experiencing random shutdown of my macbook, like if i woke it up from sleep it keeps happening where it just completely shuts down no explanation. i've tried resetting power management, i believe it was option, apple, p and r. still does it.
any suggestion on what i can do? i'm beginning to really fear that i'm getting problems on my mac like a PC does.
@my

Command-Option-P-R simply resets the PRAM. The power management reset is here:
http://docs.info.apple.com/article.html?artnum=303319
And if you find that does not help, you don't have a plastic blocking the rear vent as this article describes:
http://docs.info.apple.com/article.html?artnum=303848
And you are taking care to manage its heat effectively:
http://docs.info.apple.com/article.html?artnum=30612
and have verified the firmware update is applied:
http://docs.info.apple.com/article.html?artnum=303880
and have no third party peripherals connected when this happens and have run the hardware test:
http://docs.info.apple.com/article.html?artnum=303605
Then I'd call AppleCare and let them know the results of the hardware test.

MacBook random shutdown w/10.6.7 update

I installed the 10.6.7 combo update this morning, and now I have a problem with random shutdowns. The problem persists even after a PRAM reset. When I run Apple Hardware Test, the short test reports no problem. The extended test...shuts down before completion (before the PRAM reset, it ran for about 18 minutes; afterward, it ran for about 90 minutes).
When I ran AHT, I did so with the system "stripped" (nothing but the MacBook), so it's not a peripheral problem.
As long as I'm active (that is, using the mouse or keyboard), it won't shut down. I did have this problem with 10.6.6, but that was related to EyeTV recording and was not a system-wide issue.

I spent a couple days off and on at the apple store. Had a brand new early 2011 macbook pro 8G I7 2.3... all the best.
It was randomly shutting down, sometimes 2-3 times a day.
After replacing everything, literally, including the entire machine, it was still doing the same thing.
Finally, a genius at the gilbet, az, apparently the genius boss, started looking at it.
The first thing he tried was turning off sharing.
It worked instantly.
So, here's one of the major causes of the random shutdown - Sharing
If you share any directory that contains operating system information - the main disk, your user account, etc. OSX will die, usually with a Kernal panic (or several of them).
It turns out that you should only share folders that have data, never anything that has OS or App information.
I shared everything because it was easiest for me on my MS network to get to and from the machine. It was always problematic to decide what to share, or to create multiple shares on the mac and then get to them from the PC side of my network. Now that is what I must do.
As soon as sharing was turned off on my main drive and on the user accounts, the random shutdowns ceased. I haven't had any since.
Now all I have left is an issue with the mouse not responding after I close the lid and reopen it. Everything appears to work, but the mouse just won't move.

MacBook-Random Shutdowns After Update

(Note: I posted that I had solved this problem by deleting an older version of Microsoft Office, but a day later the problem resurfaced)
1st Indication of a Problem--
While using "Software Update" to upgrade from 10.4.8 to 10.4.9, the computer screen went black about 1/2 way through the "system optimization" part of the installation. I thought it had just gone to sleep since the white sleep indicator light was glowing on and off. However, I could not wake it from sleep and the only solution I found was to hold the power button down to fully stop the computer. Then, I powered on again to have the computer try to start up, and then go black during the gray screen. I repeated the process and each time it would get a little further into the startup process, but it would never finish loading.
Troubleshooting Steps Taken-
After reading about the proper troubleshooting methods, I booted from the install disks and ran "disk utility" and repaired the disk permissions as recommended, and ran the "verify disk" part of disk utility. The permissions were corrected and the disk verification process indicated the disk was ok.
I restarted the computer and everything appeared to be fine until I opened MS Word. The screen went black again.
Concerned that maybe the update never fully loaded, I downloaded the combo intel updater and tried to reinstall it. The computer screen went black at the exact same point during the "system optimization" stage.
At this point, I decided to try to boot from the installation disk again and run disk utility. However, the computer now would not boot from CD, while holding down C. However, it would perform the Hardware Test by holding down D. So, I ran the hardware test and it indicated no problems.
After restarting computer, the same black screen crash occurred while trying to use various applications. Not all would cause the crash, some crashed it, some didn't. The error was not consistent. The same program that appeared to cause the crash one time would run fine the next. Other times I would let it sit without opening a program and it would crash after a random period of time. It is important to note the fans aren't even running when this occurs, nor does the processor seem to be running fast.
Since I could not boot from the installation CD, I decided to run disk utility while logged in normally. Again, no problems found with the disk and this time no permissions were corrected.
So, I continued the troubleshooting process:
*I verified the S.M.A.R.T. status = verified.
*I checked the build number of the OS to ensure the update was complete (build = 8P2137)
*Checked the RAM in the hardware profile, both slots indicated OK
*Turned off all non-system fonts
*re-installed Java just in case
*Downloaded Cocktail and ran:
1)all cron tasks
2)cleared the caches
3)rebuilt launch services database
4)updated locate and whatis databases
*ran FSCK
*reset the PRAM
*Reset the system Management Controller (SMC)
*tried to login in verbose mode- crashed
*tried to login to safe mode- crashed
None of this worked, so when I could get the computer to stay up and running for a few minutes, I decide to delete unnecessary programs including MS Office.
Immediately after deleting Office, I stopped having problems. I could now boot from the install cd, boot into safe mode, run without crashes so to speak. That was yesterday... Everything seemed fine so I re-ran some of the cleanup processes above to be sure that things were clean.
Today, I used the computer for over two hours without problems. Then instant crash out of nowhere. Same problems above reappeared. It took several cycles to get the computer to load. I opened iTunes to see if that might be the cause since I upgraded that yesterday after the problem ceased. Sure enough the computer crashed. So, I deleted all of itunes except my music library. Still random crashes occur.
I resorted to opening my RAM slots and resitting the RAM to be sure it was secure and it was fine, no change... still crashes.
Two Important Notes:
1)I have never experienced the black screen of death before.
2)I updated the firmware shortly after I got the MacBook because I heard of the potential problems. So, the SMC is up-to-date.
At this point, I am going to schedule an appointment with the Genius Bar for Tuesday. However, I am sure they will merely jump to an "archive and install" which I can do myself if I have to or they will try to check the RAM which I already did.
Is there anything else I can possibly do to fix this myself before handing over my baby to them?

I mention this because you have done such a thorough job of troubleshooting and documenting your problem. According to the link below, the system optimization step in Apple's software installation has a bug that can delete arbitrary file(s) from your system.

Macbook random shutdown

I have an apple macbook running mac os x version 10.6.8 and I have had this for about a yr to two at the most. It has just recently started to shut it self down, and has done so twice in the last hr alone. I have made sure to check for all software and firmware updates, and every time I try to update, a message appears saying that this computer does not need this update. I was wondering if there were any ideas or fixes I could do to solve the problem myself, or should I just try contacting apple care?

I had the same situation and this is how it got fixed.
One morning i had macbook pro late 2011 shut down on its own.
It then repeated 3 times, within first 10 minutes of being up. i booked a Genius oppointment, and visited apple store. Genius Joshua found nothing wrong, but reset the power settings, and asked me to work on my computer a little. I did, and it worked great.
When i got home, i shut down with no responce from charging cable (no green or orange led). i took it back genius took it in. When i got it back the maglite chip was replaced and i was asked to bring in my power cable so they could test it too for damage.
my bill was zero apple's internal bill was 49.23 USD/
That's how my macbook went through forced shutdown. Thanks my macbook, genius, apple warranty, apple walk in techsupport policy.
i hope its helpful.

2.5 y/o macbook develops random shutdown?

Hi,
my 2.0 ghz core2duo white macbook has done the random shutdown thing 2 nights in a row, and its never happened before. no warning, no prior indication, it just instantly shuts down. I haven't heard of this developing on an older macbook. Both times the computer was under light load, on battery power and had maybe 20% charge left.
I did see one thread where on old battery may be an alternative cause, so I downloaded the suggested coconutbattery, which tells me my battery has a capacity of 4036 mAH now, as opposed to 5020 when new. I don't know if this is significant but it doesn't seem that 80% of the original battery capacity is too bad.
Does anyone have experience of this happening, or any helpful info for me?? This is a pain as I was hoping to use my macbook for some live music soon... not too confident of that now.
thanks, Simon Gregory

I'm not sure resetting the SMC is good advice, according this article:
http://support.apple.com/kb/HT1894
It says only to do it very very specific issues, and random shutdown is not one of them. The article specifically warns against doing it as a troubleshooting measure...

Random Shutdown: Locked Clockspeed, Processor Voltage Correlation?

I use Hardware Monitor to keep track of more sensor readouts than just temps. I recommend everyone install it. Using it, I've discovered some weird behavior in the processor clockspeed and voltage that correlates in a predictable with my typical macbook random shutdown problem. I wonder if others witness the same correlation.
Normally, according to my sensor readings, the clockspeed and cpu voltage fluctuate frequently and continually, presumably according to the demands on the processor. Clockspeed typically runs between 1333Mhz and 2000Mhz, voltage between 1.00 and 1.30V.
When running like this, it is subject to random shutdowns at any time, but most especially — indeed with absolute reliability, so to speak — within ten minutes of waking from sleep — regardless of whether i'm using mail, surfing, playing music, or running intense calculations and (so far as i can tell), regardless of how many or few processes are running simultaneously, and regardless of temperature readings. Indeed, now with the new firmware update my temps are quite low. In fact, since the computer most reliably shuts down soon after waking up, it's temp at shutdown often registers no more than the mid-50s (it'll shut down at 47).
After the macbook shuts down, it refuses to restart reliably with a simple press of the power button. Like many others, I have to hold down the power button for about ten seconds, until I hear the pained protracted beep, before the computer will enter into the normal booting process.
After it boots up like this from a shutdown — and this is what I haven't seen enough commentary on — the processor speed remains locked at 1000Mhz and the voltage at .99V until the computer goes to sleep again.
While the computer is locked into this slow-clockspeed-low-voltage mode, it is absolutely reliable. It never shuts down randomly. It runs much slower. Which is really noticeable and frustrating when using any graphics-intense or movie app.
So my questions are:
Does anyone else experience this sort of locking processor behavior?
Why would the processor lock like this?
Is it possible that the sensors are wrong? That in fact the processor is fluctuating normally but now the computer doesn't "know" it?
How would the processor's ability to vary its clockspeed and the voltage it draws affect its propensity to shutdown randomly?
I would be grateful for the observations of others regarding clockspeed and voltage at shutdown and after rebooting.
Thanks.
macbook 2.0 Ghz, 1.25GB, 80GB, week 20 Mac OS X (10.4.7)

hi
I have exactly same problems and symptoms.
It was a refurbished week 20 unit from apple uk it arrived in excellent condition and worked perfectly for two weeks without the fan comeing on at all it was perfectly quiet but hot.
As this was my first mac I was unaware that this was abnormal I had heard that they ran hot but being new to mac I was on a learning curve. Then two days after the remorse return period it began to shut down the first time was after a period of sleep just after I opened the lid. It then was and still is impossible to start it from warm or cold in the normal way, but only by holding the power down until beep. Then it will work for days at 27 deg c without a problem all be it at the 1 gig reduced speed which as you say is frustrating to say the least. Applecare UK don't acknowledge the problem at all they just want to treat it as a normal warrenty repair at my inconvenience. I am at present awaiting a more generous response from apple. I'm demanding a replacement unit but they just want we to fill out their standard web questionaire. (with non relavant tick boxs) If only one could speak to a real knowledgeable individual at apple I'm sure I'd get some satisfaction. But in this age of executive big bonuses what can one expect.
I hope Apple get real with this soon because the disscussion forums are getting overloaded with this issue its getting harder to login have you noticed.
yours unhappy customer.

Random Shutdowns (Driving me crazy)

After owning my MacBook for about a month, just 2 days ago, my MacBook randomly shutdown right after I booted it up. Then when I went to power up again, it immediately shutdown after the ding start-up noise.
The shutdowns have gotten more frequent and sometimes I have to try about 3 power ups in order for it to stay on.
Just a note (but I don't think it's related) I installed Windows XP through Bootcamp yesterday, however the shutdowns had already been occuring a day or two BEFORE I installed it.
I am using upgraded RAM (2x512mb), however it's the RAM that Apple provided me with, and therefore I don't have the stock 512mb original RAM. It was already upgraded the day I got it.
Other than those two significant changes to my MacBook, nothing else is different.
Again, note that these shutdowns have occured after owning my MacBook for about a month. (I bought it at the end of July).

contact apple care. this is a relatively common problem. Either go to an apple store or send in your macbook and they'll fix it. It took them about two days to fix mine and I've had it back about a month now with no problems.

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.

Random Shutdown plagues Macbook Pro C2D as well?

Hello everyone,
I know the Macbooks suffer from random shutdowns, but I thought this issue was fixed in the recent models. Apparently, it's still a problem since my brand new macbook pro core 2 duo exhibits random shutdowns when it gets too hot. Yes, I have all my stuff up to date. No, the new firmware does not apply to the Core 2 Duo MBPs.
My question is, is this still a known problem? I haven't really hard of Macbook Pros suffering from this, is this also common with Macbook Pros?
My Macbook does not get extremely hot to the touch, contrary to some of the "Hot" threads on this board. But, I guess it's enough to short the circuit that causes immediate shutdowns. It's easy enough to avoid, but I'd like to push my Macbook to it's fullest without worry of shutdown.

Well, this is what I've found out ...don't know if that will mean anything to you, but does not seem very good to me. Note that this was prior to the date I received my MBP.

First Crash --> computer suddenly OFF !
i've had 5 or six crashes since I received my MBP on Nov. 15th. Apple told me it must be a hardware problem. I have other stuff to read from the console if you're interested caus' quite frankly this does not make a lot of sense to me.

Random Shutdown MacBook - accept replacement or moneyback?

After 4 months of attempted and failed repairs on my young brother's MacBook, Apple has finally accepted defeat and agreed to replace his MacBook or give him his money back.
They assure us that the current crop of MacBook's (post-October) do not suffer from the random shutdown problem - but I cannot trust their word given how many times they have falsely assured us the problem had been fixed over the last few months.
My question to the Apple community is simple - do the recent crop of MacBooks still suffer from the Random Shutdown problem? Should my brother just get his money back and shop elsewhere?

This isn't much of a reply to the topic. I am new to Macs. My wife and I shelled out what is a good deal of money to us on two of the new mac books. We brought them with us to Thailand. Her computer has the random shut down thing. She loses work all the time. Safe to say she is not happy with my decision to make the switch to Apple. Sometimes she will be typing an e-mail or a word document and a half hour of work will just vanish. She has had to re-set her desktop settings two or three times as they keep resetting back to the origional factory settings.
My computer has a few problems of it's own. The hole in the case for the tracpad and button wasn't cut right so The whole cover needs t be replaced. This was diagnosed by a Genious at one of the Apple stores. I also seem to get electric shocks sometimes from the right side of the computer were my wrist rests when I type. My computer also freezes all the time. Just fozen like a PC with no way out (force quit won't work). The computer also opts to erase my computer and desk top settings from time to time.
The problem is we are stuck. We can't sent them out to America for repair or the government of Thailand will make us pay 1000 dollars each for import tax. You can carry them on your person, but they get heavily taxed when shipped.
I want to be happy with my investment but these computers were very expensive and they really shouldn't be breaking down all the time and freezing. In fact I suggested we get them because we didn't want computers that broke down and froze all the time. My wife is pretty unhappy with my decision here.

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.

Very upset at macbook random shutdown
