MacBook Pro Random Shutdown. What's wrong? What can I do?

I just got a Macbook Pro 15" i5 about a month ago, but something weird has been going on. A couple of days after use I was using my computer and closed it for a few hours. When I came back to it, and opened the lid, it was no longer on. I thought I may have shut it down and forgot, but then it happened a couple of times again. It hasn't happened in the past week, so I thought it may be okay now. But I've recently (last couple of days) been watching things on my laptop and it seems that when the laptop is jogged, the video seems to pause. I thought it might be something I'm doing, but I never had this problem with my old mac. I think I should go to the store to get it fixed, but I was wondering what the issue is and whether I can do anything to correct it. It seems to me that it's a hardware issue and the laptop is somewhat unstable, but I was wondering if anyone had any insight. Thanks for your help. =D

Yeah, I was already planning too. But I was wondering if anyone can provide any insight before I do. Or if anyone else has experienced this issue. Plus, I was wondering...if I just go down there will they be able to do anything, or will they make me book an appointment with the Genius Bar?
(Also, what is AASP?)

Macbook pro random shutdown "are you sure you want to shut down?"

Firstly, I'm asking this on behalf of my boyfriend who would ask himself if his computer were working!
His MacBook Pro 2.2GHZ new since July07 has just now, when started up, started displaying the shutdown message "are you sure you want to shut down?" and then shutting down anyway. Without being asked or prompted.
This has happened everytime it has been switched on after a couple of minutes it will just do it over again. It is fully charged.
Absolutely no idea what to do other than to take it down to the Mac Store and get it looked at.
If anyone has any help or advice it would be greatly appreciated,
thanks in advance. Charlie

Ok thought i had this fixed myself, i put it down to over heating as it was just acting normally for the last couple of hours but having just turned it off and started shutting everything down for the night it turned itself on!
I think i solved this by shutting the laptop but this has never happened before. I really hope someone can help, I've googled the problem to no avail and this is pretty much my last hope.
Thanks again
Charlie

MacBook Pro Random Shutdown

I bought a new MacBook Pro about a month ago and everything was working fine until last Friday when my MBP suddenly shut down. I thought it was because I was away from the computer for a while and it was on battery save mode, but when I tried to boot it up again, it shut down after about 10 minutes. I turned it on again and it lasted for another 15 minutes before it shut down again. I'm not really sure what I should do at this point - is this a common issue?

Were you on battery power? AC? What's your remaining battery capacity?

New Macbook Pro - Random Shutdowns

I got a 15" MacBook Pro 2 months ago and today I started having lots of problems. The macbook will start and then after a few minutes, it will randomly shut down. After each shutdown I cannot start the computer again. Pressing the power button does nothing. After about 5 minutes of shutting down the computer will start again on its own and then shutdown again in a few minutes. And the cycle continues like that. This happens while the macbook is plugged in as well.
I do not think it is a battery problem because I removed the battery and turned it on while it is plugged in and still it is the same problem. I don't think it is a software issue because the same problem happens when I boot in both Mac OSX and Windows XP. Anyone have this problem?

Hi dennyhle,
Boot up from the osX dvd holding down the 'c' key, wait for the language screen to come up, pick a language and then from a menu choose Disk Utility and check the permissions and the drive for errors.
If the problem remains after that boot up from the osX dvd again but this time hold the 'd' key to start the hardware test, run an extensive one.
Hope this helps.

Mid-2010 MacBook Pro random shutdown

Hi all, hoping you can help me with my very annoying shutdown issue. Sometimes it will happen within minutes of boot and sometimes the MBP will run for several hours without issue before it happens.
I've been able to replicate the shutdown across OSes (Snow Leopard, Lion, Mountain Lion). Initially I thought it might be bad memory but through swapping memory and running the AHT on a loop for several hours I've determined memory isn't the issue. I've reset the NVRAM, PRAM and SMC several times with no luck. Hard drive and battery is working properly and the AHT is finding no errors with the logic board. Pretty sure I've tried everything I can before bringing it in for service. And of course I'm just past the 3 year warranty date. Help!

You have the MacBookPro6,2, the Edsel of Macs. It may be covered by this program:
MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video
Make a "Genius" appointment at an Apple Store to have the machine tested. The routine hardware diagnostics used by service providers may not detect the fault. There is a specific test for this issue.
Print the first page of the panic report, and the support page linked above, and bring them with you.
Note that the replacement program only applies within three years of purchase. If you wait beyond that date, Apple may refuse the service. In that case, you'll be quoted a price of about $300 (in the U.S.) for a depot repair.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
*An SSD doesn't need to be zeroed.
You may be able to stop the panics by disabling automatic graphics switching in the Energy Saver preference pane, but that's not a solution.
Most likely, the logic board will be replaced. Sometimes the replacement part is also defective, so be prepared for that possibility.

1 yr old Macbook pro random shutdowns on or off power

I have a MacBook pro thats about 1 year old, Mac OS X 10.6.8, completely updated, 2.66 GHz Intel Core i7.
It is randomly shutting down for no apparent reason... it happens about once a day, sometimes on the power sometimes when it's not, the battery time doesn't act strange at all, the temperature seems to be fine when it happens as well, between 60-70c like always. The screen goes blank, doesn't respond to anything i do, all lights are off, and then I hold down the power button and it makes a pop noise. I then turn it on again and its fine, and gives me an error report. It doesn't seem to be associated with any application... happens when I have just chrome open, just firefox, entourage, or word, any combination of those...Any ideas? It is definitely worrying me, especially since my warranty is pretty much just at the end of it's rope.

Sounds like a power supply problem (not portable power supply), but I wouldn't want to bet on the specific issue. I realize that your MBP is not in warranty, but you might do well to visit your local Genius Bar to get their input.
This is an interesting problem; post here with the results.

MacBook Pro Random Shutdowns

Hi all,
My MacBook Pro has just recently begun randomly shutting itself down. I'm not sure why, but I have gathered that it's a known issues. Here are the specs on my laptop:
-2.4Ghz intel core 2 duo
-4GB of RAM
-500GB HD
-Nvidia 8600M GT graphics
I forgot exactly which model this is, but I've had it for a good two years now. The warranty ran out last January, and I had the logic board, disc drive, and screen all replaced by Apple right before it did. I am already on my second battery, and this one has lasted just over a year. These things suck. Here is the battery info:
Battery Information:
Model Information:
Manufacturer:    SMP
Device name:    ASMB012
Pack Lot Code:    0002
PCB Lot Code:    0000
Firmware Version:    0110
Hardware Revision:    0500
Cell Revision:    0200
Charge Information:
Charge remaining (mAh):    1323
Fully charged:    No
Charging:    No
Full charge capacity (mAh):    2435
Health Information:
Cycle count:    538
Condition:    Replace Now
Battery Installed:    Yes
Amperage (mA):    -1995
Voltage (mV):    11193
It switches back and forth from "replace soon" to "replace now". I realize the cycle count is very high and it is past it's lifetime apparently.
So, my two questions are: why is my computer randomly shutting down? I think it could be the battery or the logic board. And is there a recommended this-party battery that is better than the Apple ones? Not only are those $130, but they do not last long at all. Between the two, I'm hoping it's the battery.
Thanks in advance!

Unfortunately, many MacBook Pros of the Core 2 Duo generation instead of going to sleep properly when the battery voltage drops below a particular threshold just shut themselves off instead. It's always been unclear whether this is due to the battery misreporting its voltage or some other cause.
As you've likely surmised, the only fix is to replace the battery, at which time your machine should properly go to sleep when the battery charge gets too low.
Note that you do have to care for your battery as well; it will help it last longer but nothing will fix the fact that batteries will only last a certain number of cycles.

MacBook Pro Random Shutdown with Error Code: 4SNS/1/40000000: TAOP

Hi All,
Hope you can help, I have a 1st gen, MBP which i've recently upgraded the HD to a 500gb. Has been working perfectly until today when it had a few instances of random shut downs and not being able to power up...
Got this error code while checking the Hardware test, but not sure what it actually means : 4SNS/1/40000000: TAOP
Anyone got any ideas?? The HD is fully compatible and has worked flawlessly since installation, but now wondering if it has something to do with that??!
Hope someone can shed some light,
Thanks!
Darren

I too have a MBP 15". After 3+ years of good operation, it's developed a sudden shutoff. It happens when the machine is hot. I can get it happen often if playing a web video in Safari.
I've also run AHT and got error 4SNS/1/40000000: TCOP
Troubleshooting:
I used the widget iStat and the utility smcFanControl to monitor the CPU temperature and fan speeds. I found a direct correlation between CPU temperature spikes, fan speed, and shutdowns. My machine shutdown/failed immediately if the CPU spiked for 2 seconds above 120 Celcius - that's a hot spike. I think it's a safety shutdown.
By using the smcFanControl, I could nearly eliminate the shutdown by forcing the CPU fans to run full speed (6,000 RPM). This way, I could keep the temperature between 68-100 Celsius. However, I could still create conditions using multiple web video playback in Safari & Firefox that could spike the temp above 120 C. I found that running fans at full speed were not enough. Something additional must be wrong regarding heat transfer or sensing. So, I'm guessing the thermal grease on the CPU heatsink is old/dry/cracked. Or, there is dust/link blocking the airflow. Or, there is a design flaw with the heatsink so that it is insufficient to cool or monitor the CPU temperature properly. Not sure yet.
I see on other forums that there is a new heatsink design and part number. The design has better thermocouple placement. And, if replaced, it will have new thermal grease.
My question is: How can I purchase a new replacement heatsink for my MBP? Anybody know part numbers or vendors?

When I plug the Lacie external disk to my Macbook pro, my computer turns off. Whats wrong?

Something certainly is wrong. Do not plug the external HHD in the MBP. Male an appointment at an Apple store genius bar and bring the Lacie with you.
