MBP shutting down w/out any warning, no indication of kernel panic etc..

Hi everyone, this is freaking me out, and it's happened about 3 times in the last couple of weeks, I can't specify anything that's triggering it, but my MacBook Pro (late 2008, 15") has shut down without any warning at all, no alerts on screen, no strange behaviour preceding it.
So far it has only happened when it was not connected to the power, which is making me even more panicky, could it be something to do with the logic board?
(luckily I am pretty good at saving work in progress)

Hi HD2600 Hater,
The error code you get when running AHT with the battery removed is normal. It just means that the test can't access the sensor in the battery itself.
Given the additional info, maybe we shouldn't take too much notice of the single TNOP result for the moment.
A bad battery will certainly cause sudden shutdowns of the type you mention, and not many of the batteries in the pre-unibody models make it through much more than a couple of hundred cycles unfortunately.
Annoying, if this is the case, but way cheaper than a logic board issue!
Cheers
Rod

  • When synchronizing my iphone4 on the computer it errors out when optimizing the photos and shuts down iTunes.  Any idea what to do to get the synch working?

    When synchronizing my iphone4 on the computer it errors out when optimizing the photos and shuts down iTunes.  Any idea what to do to get the synch working?

    OKay, here is the deal. You cannot change the location of encrypted files nor can you share them with other machines. There is no file server for iTunes so even if you export the movie index from iTunes to an external volume, each time you reboot your computer itunes has to reindex the external drive every time you want to access the files. The second you run your mobile computer without the external drive or try to access the HD movies from another device or another user on the same network, the indexing gets out of synch. The entire process is self defeating regardless. The HD movies are encapsulized by apple to stream to your devices via iCloud and NOT via Cloud. Only your TV can play 1080p. That single file you download from iTunes has mutiple versions of the same video in the capsul, one version for each type of apple device. There are no 1080p apple devices except for the Apple TV. When you buy a movie you are buying a license and not the movie. It's going to get worse with all the new copywrite laws. Already you cant share any apple devices with other itunes accounts. Your airport express just stopped streaming music to all users on the local home sharing Cloud. Only the one user for each device and soon only airplay speakers connected directly to the device. No more passthru via your TV and no more file sharing with other accounts on the same wi-fi. All the ISPs are doing the same thing. And soon everybody will be buying their phones and TV's and iPads from the cabble guy.
    Apple has done a poor job of educating the consumer as to the difference between the Cloud and iCloud. They are not the same at all.

  • MBP shuts down when battery at appox. 30%

    Hello,
    I have a 17" MBP 2.33GHz Intel Core 2 Duo.
    Recently (in the last 3-4 days) it has decided to shut down completely when the battery charge falls to around 30%. Prior to these symptoms appearing, it behaved normally with the 'low battery warning' appearing at about 5% and then going to sleep mode as opposed to shutting down.
    I have reset the SMU by removing the adapter, battery and pressing the power button for 5 secs. Unfortunately the symptoms remain. Obviously I cannot re-calibrate the battery as it won't carry on below 30% charge without the MBP shutting down.
    I'll be taking a trip to my local Apple dealer in the next few days but was wondering if anyone else here has any further suggestions I could try.
    Many thanks in advance.

    Umm... of course Apple will do something. I do not understand why you felt you had to add that to your reply. Allow me to explain:
    1. I have AppleCare, therefore if it's a hardware issue then any repair will be carried out without any cost to me.
    2. Apple have introduced a 'battery exchange and extension' program:
    http://www.apple.com/support/macbook_macbookpro/batteryupdate/
    If the battery is at fault, regardless of whether I have AppleCare or not, the battery will be replaced as it falls within the terms of the extension program.
    I have just now reset the PRAM and am running on battery power. I'll know in the next couple of hours whether that has had any effect or not.
    Meantime, if anyone else has any additional suggestions as opposed to 'me too' type replies I would be very grateful.
    Many thanks.

  • MBP shutting down unexpectedly even though battery meter still has charge

    Hi,
    just in this last week, my MBP has been shutting itself down very suddenly when on battery power when there's still charge left.
    At first there was about 25% charge left. Over the next few days, that went up progressively till today it is now shutting itself down with more than 50% charge left.
    Has anyone had issues such as this? and what should i do to rectify it?
    I'm going to try recalibrating the battery.
    I don't usually use the MBP with the power connected
    I try where I can to charge and then disconnect and use till power is low.

    I was having same problem: meter shows plenty of charge left, yet MBP shuts down. When I decided to take a look at my battery (also with recall in mind) was horrified to find it swollen and warped so badly -- pushing out of its casing. Could barely get it out and then back in. That I'm getting any charge at all amazes me considering how badly the battery is misshapen.
    Has anyone else had this problem? I'm beginning to think Apple's not being quite up-front about the seriousness of the problem: Yes, MBP gets hot, yet no more than my old PowerBook and iBooks.
    But, had we been given batteries which are perhaps really unsafe, not to mention causing lost work time and maybe systemic difficulties?

  • MBP shuts down on AC power

    sorry for the long post.
    Got my mbp back from apple with new logic board and battery after repeated kernel panics. 2nd day in after running new battery down to about 20%, plugged into AC and poof, mbp shuts down. Will not boot up while plugged in. Installed secong battery and boots up fine. BUT, after this battery goes down past 30% and upon plugging into AC mbp shuts down again.
    Pulling battery and running on AC alone works fine, but cannot work while charging. Must keep it off and charge until green light on magsafe.

    Took in to apple store. They replaced the logic board [again] and the whole power connector assembly for the ac adapter. Also the left fan and the temperature control gauge(?)
    Well that's it folks! We're back up and running now!
    thanks for the views and replies.

  • 2011 MBP shuts down when connected to external display

    I've been using my 2011 15" MBP for about a week now with no problem until today when I tried to connect it to my old 20" cinema display. I have the mini display port hooked up to the dvi adapter and a usb connection hooked up to external keyboard and mouse. Everything works just fine if I keep the lid up on the MBP, but if I shut the lid, the MBP shuts down. Down, not that the big screen goes black & then comes on again. It turns itself off.
    Any way I can avoid a trip to the Apple store? In the past, the "geniuses" knew less about external displays than I did. Is there an issue because of the dual graphics cards?

    no - I realized later that the machine doesn't shut off it just acts like it. The hard drive stops spinning & the screen remains black no matter what I do. This doesn't happen when I just shut the lid & then go back to working on it.
    Then if I shut it again & try to get the monitor to respond, I get a blue screen of death color with a two inch band of blue noise along the left side. Very weird.

  • MBP shuts down suddenly when running in battery mode

    Hi
    I am from Zaragoza (Spain) and lately (about 2 months ago as I can remember) my mbp shuts down when running in battery mode and without any advice. I see some of you also have this problem.
    I thought it was me not seeing the low battery indicator but last week I realized the battery was above 40%!!
    This problem has been repeating and the battery level was between 40% and 60% when my computer shut down.
    What am I supposed to do? My MBP is still in warranty and I bought it in the online apple store.
    Thanks for the help.

    In the system profiler it says the cycle count to 24. The laptop is from late March 2008.
    The battery info is the following:

    I did the SMC reset, but I cannot complete the Battery Calibration, the laptop shuts down at half charge battery and does not go to sleep mode.
    Thanks for your help.

  • MBP shutting down by itself

    Help!
    I don't know why my MBP shuts down by itself,
    the first time it happened was when i was burning something from idvd
    then it happened again when I was just typing something, then again when I was just surfing. Then when i tried to turn it on, it went off again..then finally it is working now.
    Is it possible this is happening because of the replacement batteries? i bought my MBP last february when it went out, so it is part of the battery recall. right now im using the replacement. what should i do?
    Macbook Pro   Mac OS X (10.4.7)  

    It's not the battery. Many of the Mac Books have a far more serious problem with their internal hardware.
    The first thing i suggest is repair your permissions.
    Secondly, make sure you have updated firmware.
    Thirdly, try reseating your ram.
    Last, alert Applecare. Tell them your problem, and the steps you have taken.
    It is likely that you will need to:
    a.) have your logic board replaced (it will take about a week, including shipping)
    or b.) need a replacement.
    I just went through all of this. If you want me to walk you through anything, just let me know.

  • MBP Shuts down immediately when put to sleep

    Hi all,
    When I either close the lid on my MacBook Pro or put it into sleep mode, or let it go into sleep mode on its own [overnight], it will shut down immediately with no warning. I've searched high and low to solutions to this problem. I've reset the SMC, no luck.
    Help?
    Matt

    Hi Matt
    Does it shut down so you have to boot from nothing, or does it show the last screen from before sleeping, in a greyed-out fashion? Your machine might be going into deep sleep and not just a nap.

  • MBP shutting down despite near-full battery charge?

    This is making my crazy, crazy.
    My battery appears to charge just fine and my adapter works as it should.
    However, if I wake up my laptop and work without the adapter, I'll only get a little under five minutes worth of time before it shuts down suddenly. No warning whatsoever.
    The machine recognizes that there is no adapter plugged in and the battery appears to drain at a normal rate. From 100% to about 95% before it shuts down.
    Can someone please help me figure out what's wrong here? (This is a replacement battery sent by Apple after I sent my recalled one in last year.)

    Some of the replacement batteries have also been defective. There are two battery replacement programs, one for specifically recalled serial numbers (you) and one for all Core Duo batteries with certain symptoms. Your battery is exhibiting the symptom "+Battery exhibits low charge capacity/runtime when using a fully charged battery with a battery cycle count (as shown in System Profiler) of less than 300+," as described on this page, which also states that the battery warranty has been extended to 2 years for all Core Duo machines.
    Be sure to check in Utilities > System Profiler > click Power that your cycle count is <300. If so, contact Apple (or go into an Apple Store) for a replacement. If your cycle count is >300, your battery is just getting old (you still need a new one, but you'll have to pay for it).
    Hope this helps...

  • My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". I replaced the power supply, reset the SMC, and zapped the PRAM, but the problem continues. Can anyone help me?

    My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". So far I reset the SMC, and zapped the PRAM. I even replaced the power supply but the problem continues. My error and system logs seem unhelpful too. Can anyone help me out?

    You can get a shutdown like that if the computer gets too hot. Make sure the air intakes on the bottom and the exhaust vent on the top are clean and are not blocked by something in your workspace like papers or the back of the computer being too close to part of the furniture. You need a good six inches (15cm) of clearance between the exhaust slot and other objects or surfaces.
    Anti-virus/internet security software, especially the "pay for" kinds, can increase operating temps. So can third-party backup software furnished with many "name-brand" external hard drives.
    Fan motors and/or temperature sensors can fail. If you have the original grey disks that shipped with your iMac, find the on that has Apple Hardware Test (AHT) and run it. If you have a failed heat sensor or fan motor, it will detect it with an error code containing "SNS" if it's a bad sensor or "MOT" if its a bad fan motor.
    AHT instructions here:
    http://support.apple.com/kb/HT1509
    Also see if your iMac 27 falls under theis Apple Repair Extension Program:

  • MBP shuts down unexpectedly when on battery

    Today my MBP shuts down unexpectedly when on battery. It started at about 50%. I seems to happen if I don't a thing for a short while when I read something or so. I most of the time when using mu MBP have it on the net cord but today I wanted to work the battery.
    Does anyone know what it could be? I have searched in the forum but the answers hasn't been satisfying. I find it weird that I have to use the keyboard or the track pad to keep going.

    Not sure what the cause is but you can try resetting the SMC.

  • MBP shuts down and requires a reboot (not a wake up)

    I have a MBP that is running 10.5.8. When the power gets low and the MBP shuts down, I have to reboot it (push the power button). This is not the case with our iBook, or MacBook (I should double check it), here we just plug it in, hit the space bar and it starts up where it left off (just like it was asleep).
    Is there some setting or ?
    Thanks

    If there is Warranty or AppleCare make Genius reservation or set up Service and take or send to Apple for resolution. If no coverage, you can use virtual Lock Button. Tap Settings App > General > Assessibility > Assistive Touch > ON > tap new white screen button > Device > Lock Screen. This can even be used to turn OFF iPhone, by holding down on it. To turn iPhone ON, connect to power, charger or USB of computer.
