MacBook shuts down when not connected to power supply

Hey everyone, I'm making this topic for an issue that has gotten me edgy lately.
My MacBook (not new) has a habit on shutting down on me instantly for some reason when the MacBook is not plugged into charge. Here is the strange thing though, if I unplug the charger plug and set it still on my desk, I have more of a chance of the laptop not failing on me, but when I carry the MacBook around, it has a 90% (guestimate) chance of shutting down on me.
Even after having the laptop plugged in for 12 hours, the laptop just goes into suspend mode.
I have to wait a couple of seconds before I can turn it back on (by pressing the power button, not any key).
Also, when I shut down more programs at certain times when not plugged in, and having the screen brightness low, the Mac does not shut down so fast.
Any advice?!
Thanks

Could be you battery. Mine shuts down when showing 40% charge left and I have to plug it into the power supply to fix it. I found out it was the battery by downloading coconut battery. It's an application that allows you to check the status of your battery (Link at bottom). I suggest you get that and when your macbook shuts down again, plug it into the mains, start it up and run coconut battery. If it shows your nearly out of battery power then that's your problem.
I was showing 40% left when it shut down. Did the above and I had no power left. It happens when the battery is old about 250-400 loadcycles
Hope this helps.

IPhone is 17 month old and shutting down when not connected to the mac any this I can do about it?

should I bring it to apple ?

Basic troubleshooting from the User's Guide is reset, restart, restore (first from backup then as new). Try each of these steps in order until the issue is resolved.
Replacing or even suggesting replacing hardware without doing basic troubleshooting first is not very smart.
If basic troubleshooting does not resolve, take it to Apple for evaluation. There is no obligation to pay for anything, the evaluation is free.

Macbook pro shuts down when not on AC power cord

Whenever i remove my AC power cord to use my laptop as a LAPTOP it turns itself off?
I don't even know where to begin any help is much appricieated

Same thing happened to me about 2 days ago...while working under battery power for just 10 minutes, my macbook pro suddenly shuts down (not sleeping, but off). i was able to restart with the power adapter plugged in. The battery was still at 85% capactiy and acutally started to recharge. however, as soon as i pulled the plug, it shut down again.
my battery is 15 months old with 315 cycles, and 4664 mAh capacity. i was about to visit an apple store for a repair and/or new battery, but received a software battery update just this morning, installed it...problem solved. the timing is a bit odd. wonder how many others have experienced this of late.

Macbook shutting down when not touching any keys

Help! I am having an issue on an old MacBook (white, not aluminum). The computer shuts down if I don't keep touching the mouse/trackpad or press keys. If updater is running, movies are playing, anything at all, it doesn't matter, the computer shuts down unless keys are being pressed or the trackpad is being twiddled.
Sometimes I get the dialog window asking "Do I really want to shutdown?" with the options to shutdown, restart, etc. Even if this pops up, the computer may still shut itself down.
This happens within the minute of not touching the inputs, usually within ten seconds.
Things I have done that didn't help:
Resetting the SMC
Zeroed drive and reinstalled OS
Updated OS
Booted from other OS versions
Booted from externals and DVDs
Zapped PRAM
Ran Fsck -f
Ran virus scans
Ran Disk utilities and repaired permissions
Ran Hardware test, no problems found
None of the above found anything (some permissions fixed, but didn't help)
PLEASE HELP!!!

Macbook shuts down if not unplugged from power but battery charges!

as written in the subject.. i can't get why it's going on. i have a macbook intel c2d and i put a new battery in it. coconut recognize it and from the general infos about this mac i see that the battery is charging and it's in good condition. if i unplug it from the power adapter it lasts bout 1 - 2 seconds and then it dies. i tried to reset the pram and so on. i can't calibrate the battery because i can't use it, i am using the macbook plugged to the power source and the battery seems to be charging fine.
should i think to replace the battery connector to the logic board? obviously my macbook is not under warranty anymore so i would do myself it.
thanks a lot

Have you had all the firmware installed such as:
http://www.apple.com/support/macbook_macbookpro/batteryupdate/
Also, did you buy the computer between Feb 06 and April 07? Also, check to see how many battery cycles you have on the battery in System Profiler and how long have you had the computer?
It couldn't hurt to try a SMC reset by turning off the machine, unplugging the magsafe, taking out the battery, and holding down the power button for 5 seconds.
Next, reset the PRAM by putting everything back in, pressing the power button to turn it on, and holding down command-option-p-r until it chimes twice.

My Ipod nano 6Th sometimes shuts down when I connect the phones, sometimes it not shuts down, but the volume and standby buttons do not work.

My Ipod nano 6Th sometimes shuts down when I connect the phones, sometimes it not shuts down, but the volume and standby buttons do not work. If I not connect the phones everything works fine. But with the phones connected it goes crazy. I alredy reset, restore and nothing. If I reset and let the phones connect the up and down volumes buttons start to work. But the power/stand by button don´t. I need to disconect the phones to the power/stand by button starts to works. Anyone already have simmilar problem?

A windows error message appears saying iTunes has encountered a problem and needs to shut down.
let's get a crash log from itunes, and send it to the Apple engineers for a look.
Typically, you'll need to configure Dr. Watson on your PC in order to generate crash logs. Windows start menu -> Run. Type in "cmd". Hit return. At the prompt in the command line window that comes up, type in
drwtsn32 -i
And hit return.
This will create crash logs in Documents And Settings\All Users\Application Data\Microsoft\Dr Watson\. There'll usually be a file in here called "drwtsn32.log"
prior to collecting the itunes crash log, delete any existing crash logs in there. (we want to make sure we send the correct crash log.)
Generate the crash, collect the crash log, and and send it as an attachment to this email address.
in the email to Roy, be sure to include the following information:
- A link to the thread on Apple Discussions where the issue is being discussed
- The username you are using in the thread
- The version of iTunes you are using or trying to use
- the version of Windows you are using (mention service packs)
- A concise description of the issue you are seeing
- The exact text of the error message you are seeing

My MacBook Pro shuts down when i connect a USB cable.

My MacBook Pro shuts down when i connect a USB cable, only when its a 30 pin apple cable. Well one USB shuts it down and the other one doesn't work at all.
it only happens when i use an apple cable. It has no problem with my external drive nor with other things.
Ps. i did use different apple cables and they all shut it down.

What are you connecting? iPad, iPhone, what?
When you say a 30-pin Apple cable do you mean a Lightening to USB cable?
Little more info needed...

My older iMac running Mavericks 10.9.4 shuts down when it connects to the internet. Resetting the SMC doesn't help. What can I do?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Imac shuts down when not in use

I purchased my 21.5" imac July 9, 2011 with Snow Leopard. No problems for 1 month. Then about August 12th or so, my imac started to mysteriously "shut down" when not in use. I'll be working on it, then get up to go pour myself a cup of coffee or something...then I come back to my computer that has now shut off. It is NOT asleep...it is OFF. So I turn it back on and it is fine. This has happened a few times now within a week. Anyone else have this problem?
By the way, I am now running Lyon, as of August 18th. When the imac shut down, I was usually viewing photos or on the web.
thanks!

First thing I would try is to reset the SMC, it can help with power related problems. Shut down the Mac and unplug everything including the power. Press and hold down the power button for 10 seconds. Plug in the computer but be careful not to press the power button as you are plugging it in. Wait a few seconds and turn it on. Hopefully it won't happen again. There is always Apple Support. Don't let the problem persist until your free phone tech support has expired (3 months). I would also recommend using the iMac with an UPS, and at the very least, a high quality surge protector.
If you have MS Word or a similar word processor you could try enabling the autosave feature and set it to 1 minute intervals. Keep a document open and if you come back to the computer and it has shut down, you can look at the last time the document was updated and know what time the comptuer turned itself off. It could be useful in diagnosing the problem.

ITunes shuts down when I connect my iPod 30gb

I desperately need help. Recently my computer crashes and I reformated it. So I had to reinstall iTunes. Ever since then iTunes shuts down when I connect my iPod 30gb. A windows error message appears saying iTunes has encountered a problem and needs to shut down. I am unable to update my iPod which drives me crazy. Somebody please help!
I browsed through some threads which have similar problems as I do, but I am unable to reply in any. It says: This topic has been archived - replies are not allowed.
There's this thread here about the problem I am facing but I doesn't seem to understand the solution to it.

Can somebody please help me?

A windows error message appears saying iTunes has encountered a problem and needs to shut down.
let's get a crash log from itunes, and send it to the Apple engineers for a look.
Typically, you'll need to configure Dr. Watson on your PC in order to generate crash logs. Windows start menu -> Run. Type in "cmd". Hit return. At the prompt in the command line window that comes up, type in
drwtsn32 -i
And hit return.
This will create crash logs in Documents And Settings\All Users\Application Data\Microsoft\Dr Watson\. There'll usually be a file in here called "drwtsn32.log"
prior to collecting the itunes crash log, delete any existing crash logs in there. (we want to make sure we send the correct crash log.)
Generate the crash, collect the crash log, and and send it as an attachment to this email address.
in the email to Roy, be sure to include the following information:
- A link to the thread on Apple Discussions where the issue is being discussed
- The username you are using in the thread
- The version of iTunes you are using or trying to use
- the version of Windows you are using (mention service packs)
- A concise description of the issue you are seeing
- The exact text of the error message you are seeing

Shuts down when not plugged in

My new (got it in July) MacBook shuts down when it's not plugged in. I usually turn it on and it will last around 2-3 minutes before shutting off completely, then if I try to turn it on it will make the turning on sound and immediately shut down. If I plug it in it will stay on. I looked at downloading OS X 10.4.8 in order to download the suggested firmwire to help with this issue, but will that cause me to lose all of my photos and everything else stored on my computer? Could there be any other solution to my malfunction?
Thanks for your help!!

Hi -
When it's plugged in ...does your battery show a charge? Also, if you press the little button on your battery (on the bottom of the macbook) a series of green led's should tell you if you have a charge. just asking this because your macbook may not stay on if your battery is not charging/dead.
Yes, you should also update you system and firmware as well.

Have you reset the SMC and PRAM?

Why does my macbook shut down when the lid is closed?

Hi,
I have a Macbook Pro (mid-2012) running 10.9.1
Last week out of the blue, the Macbook started shutting down whenever I close the lid.
When I open the lid, the logon screen appears (as if it's been asleep as normal) but almost immediately reboots itself.
Has anyone else got the same issue? Any idea how to resolve?
Thanks

If after you open the lid you do get the login screen, almost immediately, but then it restarts your system is not shutting down when you close the lid. It is going into a sleep state but then crashes when trying to come out of that sleep state. There are quite a few posts on this problem and it seems to be caused by the system going into the Deep Sleep state also known as the hibernate mode. That is where the contents of the RAM is written to the hard drive and the system suspends supplying power to the RAM chips so the system uses even less power then in regular sleep mode.
That is only supposed to happen after the system has been in the regular sleep mode for an extended period of time.
To check the state of the huiberbnate mode open terminal and type in, or copy and paste, this command.
pmset -g | grep hibernatemode
To check the state of all power management settings use the command.
pmset -g

Macbook shuts down when plugged

I have my macbook for 2 years, and last month it started to behave in a weird way.
First when I let the battery drain out it shuts down when the battery reaches around 2-3%, it doesn't go into deep sleep. I've checked the battery capacity and it's around 2852mAh, and the check battery sign just started to pop. I'll probably have to buy a new battery. (That doesn't bother me much, because I use it mainly plugged on power.)
But last week it has gotten worse, now my macbook started to shut down when it's plugged. It takes a minute so I can reboot it (not even the battery indicator works for a while), and the charger stops working right after it's off. I'm using a new 85w charger (the old one got ripped off), because they don't sell the 65w here in Brazil. Needless to say I've tried do reset the SMC, PRAM, NVRAM.
Ps: On january I upgraded my RAM with some used module I got from buddy of mine.
Pps: You should know that there's no apple store in Brazil. Don't tell me to ask the genius :P

I took my macbook to a apple technical support provider, and they're replacing my charger. I wonder if the faulty charger could have damaged my battery, the check battery sign first appeared after the shutdowns caused by the charger.
