Computer Shuts off Without Warning and with Full Battery

I have been having a problem with my Macbook Pro, where it will shut down completely even though the battery is full.
It is a fairly new battery, because I had it replaced back last fall. When it shuts down, my first instinct is to try and turn it back on. When I do this, it starts up normally, goes to the white screen, but then shuts down again...
However, when I wait about a half hour and try turning it on again, it will boot up normally. It also works fine when plugged in.

Add me to the list of people with a MBP (with a new battery) that randomly shuts off under a full charge. Sometimes it is under resource intensive games, other times it is when I am checking email with nothing else open. If I hit the power button after a random shutdown, the machine will not start. I either have to wait for a while, (10-30 mins) or plug in the magsafe adapter.
IF I unplug the magsafe adapter while booting, I will get a random shutdown in the middle of booting. I cannot explain the behavior - I've tried recalibrating my battery, SMC reset, etc.
I put the battery into my other MBP (a 1.83 ghz Core Duo) and it reported a 90% charge and ran for hours without a random shutdown, so I am quite sure that the battery is not at fault.

  • Computer turns off without warning on battery power

    Starting a few weeks ago I've found that my Macbook Pro has been turning off without warning while on battery power. The first time this happened it was after about an hour of use and now it happens within a half hour or less. If I try turning it back on it shuts off before OS X is fully loaded. According to CoconutBattery my battery's health is at 97%, so the battery isn't losing overall charge capability. When I'm on battery power it says I have 2-3 hours of battery life left. Sometimes I notice this will drop between 1-2 hours after 20-30 min of use (if it'll stay on that long) but it never drops and gives me a warning of low battery. It just shuts off without warning. If I press the button on the battery after this happens I do get 4 out of 5 lights. This never used to be a problem. My computer is 14 months old. I've replaced the battery once about 8 months ago (under warranty) because my original battery was losing capacity very quickly. Because 14 months have passed I can't simply get a new battery under warranty. According to Cocoanut Battery and the Finder my battery should last near it's full capacity. I can't figure out why it's randomly shutting off. I have had all the latest updates including the recent battery patch. Any help would be greatly appreciated. I will award "solved" for a solution and "helpful" for posts that contribute to the solution. thanks!

    Actually (and fortunately), that's incorrect. Apple extended the warranty for all Core Duo notebook batteries to *2 years* from date of purchase. Details are here:
    http://www.apple.com/support/macbook_macbookpro/batteryupdate/
    Your full charge capacity is fine (as you noted). But one of the symptoms listed on the linked page is +"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."+ The word runtime in there applies, so I would call Apple or make a Genius Bar appointment and head into a store. (I did the latter, they replaced mine - free of charge - 15 months after purchase, no AppleCare, and no hassles).
    Hope this helps...

  • MBP shuts off without warning on battery...

    In the last 3 days my 17" MacBook Pro shuts off with 17 mins left of battery. It doesn't give the running of reserve power warning it just shuts off. I bought this MBP in August 2007. I have reset the PRAM and did SMC reset. Is my battery going bad?

    I recently began experiencing the same symptoms described in that thread where my battery would get to about 80% and then the unit would shut off without warning. I purchased my MBP in 07 and the battery Model No. is A1175. It shows only 87 cycles. There is a replacement program for that model battery, but my serial number wasn't included. I still have about a year on my Apple Care so I called and, while they were quite helpful, asked that I stop by an Apple store to have someone look at it to rule out any problems with the computer's energy systems.
    So I stopped in last night, and the tech confirmed it was the battery. His initial comment was something to the effect that battery warranties are only one year, but after clicking away at whatever he was looking at on the other side of the counter, he confirmed that Apple would be sending replacement free of charge. So it appears to me that this is becoming more of a widespread problem and for those running into this, I would encourage you to complain firmly to Apple Care and your local store and hopefully you'll get a free replacement as well.
    Good luck

  • HP 250 Laptop - When running on battery turns off without warning and won't restart

    One month after warranty expires this laptop presents with this problem. It shuts down without warning when running on battery, although the battery has plenty of charge. Following shutdown it won't restart on battery. Plugging in power and restarting it displays a message that the battery is cactus before continuing to boot. When trying to run F2 on startup battery check it simply doesn't progress past the initial screen (1%) and [esc] key does nothing. Need to power off. However, REMOVE the battery, boot the computer, shutdown, REINSTALL the battery, turn on and everything is OK - most recent example showing battery with 95% remaining. Continues to work for a few days until it decides to fail again. Suspect the battery is not at fault here, and in any case can't get a replacement (thanks HP for providing equipment with rare and unusual parts) - one supplier has only two on order which will be delivered some time in September!! Usual third party providers don't provide a replacement for this battery. Have seen a lot of references to this sort of mystery "battery failure - shutdown with warning" but no concrete solution. Have tried different power setting including never hibernate, but these seem unrelated. Open to useful suggestions at this point.

  • TouchSmart 610-1115uk Randomly Shuts Off Without Warning

    i have had this TouchSmart for about 2 years now and it is in immaculate condition. physically apart from dust, which i clean out regularly, you'd be mistaken for thinking it was new. in terms of operation i have always been careful to look after it too, running regular scans of the HDD and hardware, updating drivers and being careful when it comes to what i download.
    i have recently upgraded to Windows 8 Pro x64 (within the last 2 months) but didn't do a clean install, i simply upgraded from Windows 7 Pro x64, and to be honest after a few tweaks the computer was working better than ever, it was faster both running programs and in terms of startup time, and graphics looked better than ever.
    then about 2 weeks ago it just shut off without warning, not shut down like if you'd asked it to, but just went blank like loss of power, i powered it up and it didn't do it again for quite a while and so i assumed it was a one off. but it soon started doing it regular. i've gone through every thing i can possibly think of trying to diagnose what the problem is, i've checked all wires and connectors, cleaned out all dust and checked for overheating, updated drivers, removed the extra RAM i'd installed not long after purchase, wiped the system and reinstalled Windows 8 from scratch, deactivated Threading on the CPU, and have reduced power to the CPU down to 50%.
    this last action did reduce the frequency of the shut off issue significantly but it just seems completely random, i can be running any number of programs and it can work fine for hours, and then i can be doing nothing on it and it will just die.
     i have run no end of diagnostics on it and they all say everything is fine, no viruses, no errors and no build up of heat (i've monitored the temperature rise when running and it never gets over 40 now with the CPU power turned down).
    please can someone tell me if i'm missing anything, and if i can solve this without HP as my warranty ran out a few months ago, thank you.
    updated: the shut off problem seems to occur more often when the computer isn't really having to process very much like when it is left idle or when i'm just using the internet, whereas if i play a game or use a resource hungry application it rarely happens.

    I'm going to reply here just in case someone else happens upon this post and wants a definite answer like I did...
    My Problem
    My computer randomly shut down as if the power had gone out. I didn't shut it down on purpose, hit a button, put it to sleep nor was it running updates and needed to restart... it simply, shut off.  It shut off much like the power goes out in a home, however all of my lamps and other electronics in my room were on. It was only my computer that shut down.
    I followed a lot of advice in the forums and it did turn back on a few times but only for a few minutes before turning off and never coming back on. 
    I feared it would be the motherboard but a friend informed me it could be the Power Supply (the brick) and I saw THIS post and thought... it has to be that... or at least I HOPED it was that... or I was switching to Mac.
    Never heard a response back to my reply to this post, and I didn't see a follow up to the guy above seeing if it worked for him.
    The Solution
    I decided to go ahead and purchase the power supply part for my computer which is the HP TouchSmart 610-1130f All-in-One series. It needed to be a 150W (hard to find but is sold in the HP Parts store).
    This is the part info: 609919-001   In stock   Powersupply - Madeline-R 150W 19V EPS2.0 Shasta 
    Upon receiving the part and plugging it into my computer, it worked. That was 9 hours ago (currently using fixed computer) and it is running just fine. I'm STILL holding my breath and hoping it doesn't go out again. If it does I will come back to the forum and let everyone know.
    Hopefully I won't be back again in 2 years to purchase a new part. Lucky it wasn't something worse like the motherboard... having a computer that only lasts 2 years? 
    Anyways. Thought you should know random person reading this. Best of luck.

  • My Macbook Air (circa ~2008, used) keeps shutting off without warning.

    Hi, guys. I'm back again with the same issue. My aluminum Macbook Air (circa late 2008, used) keeps shutting off without warning. It comes back on as if nothing has happened, and I can even unplug as soon as I press the power button (twice, once to do...something, and the second to turn it back on). I have a brand new battery, so I know it's not that, nor is it an overheating issue. This is becoming very frustrating for me.
    Before you recommend: I cannot possibly get to a Genius Bar appointment, because, unfortunately, Apple has no stores in West Virginia.
    Thank you all for your help!

    And have you already tried to reinstall the OS and you put in a new battery?
    cant be monitor or fan, only possibility is onboard Ram / logic board or the SSD is going bad.
    If the logic board / memory is bad,...the cost of which  would make repair a bit counterintuitive to replace given the age of the unit.
    Does it does this plugged in or only on battery?  Does it hold a full charge.

  • I have an hp a6130n desktop that will shut off without warning. power button turns orange

    I have an hp a6130n desktop that shuts off without warning. The fan goes ballistic and the power button turns orange and the only way I can get it back on is to shut off the power strip it is plugged into. Any ideas?

    Your system was released back in May of 2007 so I suspect you've had it for a while.  I know that the CPUs have self preservation modes that  will react if the processor gets overtaxed.  Try cleaning out the system with some of that air in a can stuff.  Blow out the heatsink and processor fins and make sure there's not a lot of dust around the vents and inside.  Make sure it's got plnty of air flow into the box. When the fan goes crazy it's the system trying to react what it feels is an excessively warm temp inside.  It can also happen when you've got a lot of different programs running that strains the system.  The information on the webpage for your system (See here) reflects a base memory of 3GBs  If you want, another GB of memory might help the system if it's a 32Bit OS or as much as 8 if it's a 64 bit system. I hope this helps address your issue. Regards

  • G5 iMac shutting off without warning

    Well, it seems as if I'm not the only one having this issue. My G5 20" iMac also shuts off without warning. This just started yesterday and it can be on for a few seconds and kill or be on for a few hours and kill.
    I already tried resetting the PRAM and SMU, but that did not take care of it. I saw the other posts about this topic and looked to see if my iMac is eligible for one of the repair extensions.
    My EMC number is 2008, not 2056 so it's not eligible for the second one. The serial number starts with W8439 and looks like it falls into the first one.
    Is this the case or am I gonna have to shell out some $$$ for the repair?

    There are in fact two programs for separate iMac G5 releases:
    http://www.apple.com/support/imac/powersupply/repairextension/

    So be sure to check your serial number and EMC number against both!

  • Lumia shuts off without warning

    I got my Lumia 800 a little over a week ago and im reasonably happy with the phone a little disappointed with the level of apps or lack of should I say but my issue is a bit more annoying twice now the phone has shut of without warning and when I go to turn it on it wont unless I hold the power button for some time in which it vibrates and comes to life but when it does the batt has plenty of life in it so I was hoping someone had a clue in what was going on cos I can't have it keep happening and would rather not have to stick it on eBay and go buy another iPhone.

    I am having the same problem on a 12 inch PowerBook. I left it in sleep mode for a couple of days and when I went to use it, I noticed that it was very warm and that it had shut down. When I hit the power button, it gave the usual chime but would not start. I tried various things and finally removed the 1 gig RAM chip to see if that was the problem and it started fine so at first I thought it was the RAM. But I put the RAM back in and it started fine so now I think it was overheating. I've noticed before when it was asleep that it was not cooling off so it seems to be drawing power while asleep. Any suggestions on how to trouble shoot this?

  • HP Laptop DV5000 shuts off without warning

    My DV5000 is shutting off without warning at different stages of starting up. It has shut down before the splash screen, after the login screen, after getting to the desktop, in regular startup and safe mode. Tried taking out the battery and unpluging the power adapter, held down the power button for 30 seconds. Tried starting up with no battery using only the power adapter and got to the desktop before it shut down. Charging indicator is flashing to indicate that it is charging when plugged in. Was working fine last night, then we had a power outage (car vs fire hydrant city had to shut off power because water was hitting power lines). Nothing else in house seems to be affected by the outage. Not sure if just a coincidence or because of the power outage that the problem started. Used canned air to blow out vent and fan areas still not staying on. Any thoughts????

    Hi,
    I bought my laptop to two years ago this past October. I have tried to boot up without the cell battery attached also. To no avail.
    I finally got it to boot up with the recovery disk. First recovery disk worked fine, second recovery disk, error message. Bad Disk
    Lost all financial records, photos, itunes purchased music!
    I am ready to throw HP's supposedly heads-above-all-other-laptops-quality product out the window!
    My little world just ended as I knew it.

  • MBP shut off without warning on 30% battery

    This is the second occurrence. Two weeks ago it shut off without warning at 10%.
    My Macbook Pro is 17 months old and the battery has gone through at least 150 load cycles. The battery's current max capacity is 3205 mAh (out of 5500 mAh, so 58%).
    Do I just need to recalibrate the battery, or is it time to buy a new one?

    Reset the SMC (System Management Controller) and re-calibrate the Battery, you should do this every couple of months. Your battery condition meets the terms for a free replacement ...

  • My Imac will suddenly turn off without warning and then take several hours before it will switch back on again

    My Imac will suddenly turn off without warning and then take several hours before it will switch back on again. Can anyone advise?

    I like that third tag...
    There's really no telling what the problem might be - you may want to try running the Apple Hardware Test (if you can) to see if you've a hardware issue. If you can't even get to the AHT, you've no option but to take the machine into your local Apple Store or an AASP and have them run diagnostics on the machine.
