My MacBook Pro turns off without warning
My MBP (13 inch, purchased mid 2010) turns off without warning. It is a 2.4 GHz Intel Core 2 Duo processor with 4 GB Memory running OS X Version 10.9.4. It happens after periods of both short and long use and has been occurring for the last few months. I keep it updated regularly. I have yet to receive a report when I turn it back on that explains the shut down. So far I have reset the SMC and PRAM as others have mentioned that it helps. No luck though. My battery lasts all day, and I don't use my computer heavily. It doesn't feel hot when it turns off either. There is simply an audible "click" and a black screen. Can anyone help explain this? It is getting very frustrating having to constantly worry that it could crash at any second.

Macbook air turned off without warning?
Hi! Last night my macbook air turned off without warning and wouldn't turn back on until I tried again this morning. A few weeks ago I had my battery and logic board replaced and since then it the screen has gone blue for a few seconds and then back to normal a few times, (in case this is related at all). Is there something I should do to make sure this doesn't happen again.
As you say it is just been repaired I would take it back to the place that repaired it and ask them to look at it.

hi. my MacBook pro went off without me turnng it off. i tried turning it on again, but it wouldnt come on. i also tried doing the SMC thing, no avail. please any other thing to do ? (This notebook is still very new for anything to be wrong with it).
There is no way I would do the smc thing with a laptop that won't come on.If it's new and you're anywhere near an Apple Store, take it in. If it's less than 14 days old you can exchange it. If it's more they'll repair it for you.

MacBook turn off without warning
My 4-year-old MacBook start turning off without low power warning while on battery.
I checked the battery level, it's usually around 20~30% once I plug it back on and restart.
Any one have any idea? I got a new battery last summer, and I really don't want to pay for another one.
The following is the information of the battery and my MacBook.
Model Name: MacBook
Model Identifier: MacBook2,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
Version 10.4.11
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 3989
Remaining Capacity (mAh): 1409
Amperage (mA): 1584
Voltage (mV): 12028
Cycle Count: 152Your battery info doesn't look bad. Have you ever calibrated your battery? This is necessary not so much for the health of the battery, but rather to make sure the battery and your MacBook are in sync. Calibrating your battery is what allows your MacBook to estimate how much of a charge is remaining. Over time, without calibrating, they can become out of sync. When this happens, your computer may think you have a 20% charge, when the battery only has a 1 or 2 percent charge. Since your computer "thinks" it has plenty of charge remaining, it doesn't alert you or go into sleep... but then the battery just runs out. Here are the instructions for calibrating your battery:
http://support.apple.com/kb/ht1490
You might want to reset your SMC first as this is a fairly quick process and see if that resolves your problem first (although you should still calibrate your battery if you haven't done so):

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... -
I wanted to calibrate the battery my new macbook pro turns off
You should perform this procedure when you first use your computer? is this true? new macbook pro on may 11 2010 what happed was today on may 22 2010 i wanted to calibrate the battery my new macbook pro turns off when it runs out of battery. 3 times Typically, when macs run out of battery, they go into sleep mode.

Resetting the PRAM (http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html) fixed the problem in my case. then i did the calibrate the battery again this time it went to sleep not shut down i did this 3 more times why?
the 3 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010the 9 more 4 in 10.6.4 forced shut downs without entering SafeSleep. with logs indicating improper shutdown, will that cause severe corruption to the os and do i have to reinstall the os now?2.66 ghz 2010 but if it happens again you should try
i hate to do this reinstalling the OS, if this do not work also, then you should call apple, or take your MBP to an apple store. on june 24 2010 i am going to talk to spence about this. so what do i do now? this happed on june 16 2010 4 more times
without entering SafeSleep. only one time it worked on 10.6.4

MacBook Pro turned off on its own and now won't turn back on.
MacBook Pro turned off on its own and now won't turn back on. Battery had 41% just before this happened and green indicator on power cord is showing, so it seems like it's charging. What should I do?
The led on the power adapter should be amber if it is charging. Green just indicates that it is supplying power to the MBP.
Try a SMC reset:

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.
Sorry,

This is a current sensor on the power bus. This seems consistent with your symptoms.
A faulty sensor on the logic board means the board has to be replaced, take in for repair:

macbook pro turns off when i unpliug
You either need to plug in your charger and if that isn't working if your machine is less than a year old take it in to your nearst Apple Store and let them deal with it. Or if you are out of warrantee you will need to get a new battery for your Mac

Problem: Qosmio 505-Q850 turned off without warning and won't start up
The unit switched off without warning leaving only the LEDs for external power and the battery lit.
When the power button is pressed, it lights up for a moment before dying again. A few seconds later it lights up again before quitting again. While it's lit up the power LED is also lit and a slight vibration is felt from the unit.
Other than the slowly blinking lights and the slight sound/vibration, there's no life from the unit. Any ideas?Sounds like it aint charging properly... could be a break in the charger wire right before the connector or the internal power connector is bad. the is supposed to run on the charger power alone without the battery intalled. if it does not its definitly the charger or the internal connector. If it does come on with the charger alone let it run for a while an then feel the the power connector and wire to see if its hot. If it is, this can be an indicator of an break in the wire or or a bad internal connector.

HT1237 macbook pro turns off with no warning...
my macbook pro (late 2011) is powering down without warning. I'll be writing an email and w/o warning, it's off. I'm unable to turn it back on with the power button unless i hold it down for a slow count to 10. Fyi - machine is 100% charged when this happens. Two days ago, I did SMC and PRC resets with Apple Care. I needed to do both of these again yesterday on my own. Can anyone tell me what's going on - do I need a new battery? Thanks

1st Gen. Macbook Pro Turns Off Suddenly, Even When Plugged In
Help Me!
My 1.83 Ghz Intel Core Duo shuts down without warning after I start it up. Sometimes it's 1 minute into the startup, sometimes its 10. But after installing snow leopard 10.6, it does this everytime without fail. My screen doesn't work, so I have it plugged it into an external monitor. When it's turned on and working, it functions perfectly. But all of a sudden, it will turn off. I copied the power information from the system profiler, which is pasted below. Any help on possible fixes would be great. Maybe some sort of MPU reset or something. Also, I tested the battery I'm currently using in another Macbook Pro of the same exact model, and it works fine.
