Computer Shuts Down Randomly

My computer shuts down when disconnected from power cord. I have to plug it back in to get it to start again. It seems to be more frequent when watching video. I have tried the SMC reset and will post my power stats below. Do I need a new battery or any other suggestions?

Hey!! Wondering if you've learned anything more about this issue? I'm running my macbook with some similar issue.. when running on batt, shuts down at random, can't find any pattern as yet.. I have found that it shuts down in Hardware test mode on batt as well.. I've done a good AHT, SMC, pram reset.. everything else is fine... just this shut-off thing... my batt is in perfectly good condition.. and plenty of charge.. I can't decharge the batt anyway, it won't run long enough unplugged!! I've thought that checking into Snow leopard might help.. but not seen anything about that yet.
Any info would be great
Thanks

Computer shuts down randomly; Battery goes flat from 1:30h to 0 in 1min

I have a strange behaviour on my laptop;
I fully charge the battery and then disconnect from power plug.
Checking the battery both through Battery icon as well as pressing the button on the battery itself shows that it was more than half full.
Within 2 minutes the battery goes from half full to a shut down and can only be revived through connecting the power cord again.
Anyone having seen this and any solutions out here
thx J

Your battery has unfortunately gone bad. After a long while these batteries can be mischarged so that even though there is only a small amount of battery power it reads as full and there is no way to fix this that I know of. Its a fact of life with most laptops out there.
If you have not tried it, to be sure, you can reset your power management and let the battery charge back up and see if it any better.

HP laptop shutting down randomly (8 month old)

HP pavilion g series, purchased new in Canada; one month in, it was constantly freezing; sent back to hp and that was fixed but came back with a new problem, random constant shutdowns; this varies, sometimes only a few times per day but sometimes constantly, every 2 minutes. Not happy with Hp at all and if they don't fix it I will never purchase another hp product again. I have in my house another hp laptop with no problems, two hp netbooks, an hp desktop and printer. This doesn't seem to matter to them that they will be losing a valued customer. Has been returned to hp for repair 6 times, going out again this week. Trying to assess it on my own. Tonight it isn't shutting down while using battery power, just unplugged power cord to see what happens. It is not hot and I do hear fans and make sure that it is elevated to keep it cool. You can't talk to anyway at hp, I want a new laptop. They can keep it, useless to my daughter who is a university student. She can't be doing papers etc with the computer shutting down randomly. She will lose her work. Thanks, so much for any input.

Okay,
Wefinally got around to calling Costco Concierge service (should be a sticker on your laptop if you bought it there), verified that we already did everything (see first post) he was going to suggest, however,
There was just one more thing to check after all:
Reboot and hit [F2] to get into another HP Utility. There is a battery check there, and that one told us
Primary - Replace (40)
So he had us hold while he contacted HP to begin a battery order for us - then he patched us thru to HP to complete the call. Of course, it would be free as still covered by warranty. Was painless, quick and best of all, that phone call was YESTERDAY mid-afternoon and guess what? We received the new battery before lunch today shipped from SC to ON. AWESOME!!!!!
I've had to call HP before about a mini and it was horrible foreign outsourced support - claimed to be in Canada but didn't know how to spell Ottawa or where it was... Going thru Coscto compared to that is night & day.

My iPhone 4 shut down randomly and the lock button is broken, it has happened before but I just called myself and it turned on. It also wont charge or connect to my computer, how do I restart it?

Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

My computer just shuts down randomly

Does anyone know why my computer would just shut down randomly? I have know idea. I ran Disk Utilities, Tech Tool and Norton and found nothing wrong. Do I need to reinstall my system again? Any help would be great.

Have a look at the logs with the Console app, located in /Applications/Utilities. Look specifically at system.log and see if there are any entries in there around the time that the computer shuts down. Look for entries with "shutdown" in them.
Oh, and what Norton product do you have? They're notorious for causing more problems than they solve.

HAMitch,
your EtreCheck report will not reveal why your MacBook Pro shuts down randomly. What this report does reveal is that you have out-of-date versions of Java and Silverlight installed. The latest version of Java (7, Update 55) can be downloaded from here, and the latest version of Silverlight (5.1.30317.0) can be downloaded from here.
Without knowing some example situations in which your MacBook Pro randomly shuts down, it will be difficult to diagnose the problem. Would you provide some examples during which it has shut down? That is, which programs are running when it happens? How long has it been booted up when it happens? &c.
In the interim, after updating Java and Silverlight, you can try running your MacBook Pro’s Apple Hardware Test, to see if it can detect any hardware problems.

My computer keeps on shutting down randomly

My computer keeps on shutting down randomly. What can I do?

Welcome to Apple Discussions
Help us help you. The more complete the description of your problem is (what OS you're using, what Application you're using, recent software installs or updates, a full or screen shot or the text of any error messages) the more assistance we can provide, and, the sooner we can provide it.
Under your profile there's no data about the age of your MBA, the OS it's using. This is helpful for us to know because there's a phenomena with machines recently updated to Mavericks that have unusual sleep/wake behavior. There are other issues particular to certain combinations of machines and software.
Is this happening when the computer is on battery or plugged into the mains (wall outlet)?
How long has it been happening?

Satellite A215 - computer shuts down at random

I own a Satellite A215-S6804, and I've had it for about a year and a half. The past six months or so, I'll be in the middle of doing something and the screen goes completely black. It often happens when I play one of the Windows games (like Spider Solitaire), but it has happened when I play a video from the Internet, also. I know it's not just the light in the monitor, because I can't see anything if I look close enough, and if music is playing at the time, it completely stops. It appears as though the computer shuts down but the screen stays on. I also have had the laptop plugged in with the battery in, but within the last month or so decided to take the battery out while it was plugged in (this made no difference; the problem still persists). What's happening to my laptop?

This has been happening to me recently. Twice this eveing. What is happening? How do we fix it? Or is something dying in it? dinkysews

Replaced Logic Board, RAM, and hard drive connecting wire, but Macbook Pro 15' (Mid 2010) now freezes and shuts down randomly

I have a mid 2010, Macbook Pro '15. Summer of 2012, it kept shutting down and making the three beeping noises, so I took it in for repair. I was told that my Logicboard needed to be replaced, so I replaced it, and took my Macbook abroad with me. Halfway through the summer, the three beeping noises resumed, and since I was abroad, I couldn't use my 90 day warranty and take it back for repair. By the time I returned to the US, my warranty ended, and I was told that the RAM actually needed to be replaced. So I replaced that.
In May of this year, my laptop wouldn't start and instead showed a folder with a question mark. I took it to repair and was told it was the hard drive wire that needed to be replaced, so I replaced that. Less than two weeks after, my Mac began freezing whenever I had a YouTube video or song playing- it made short, staticky sounds and then shut down. Now, it shuts down randomly even when I'm not playing videos or songs, and regardless of if it is running on battery or plugged in. Since I got my hard drive wire replaced, I've also noticed that the laptop takes an incredibly slow time to start up.
The last the Genius Bar technicians looked at my computer when replacing the harddrive wire, they hadn't said anything else was wrong with my laptop.
I've spent almost $1000 total fixing my macbook and am quite sick of going through this over and over again. Can anyone help me know what went wrong this time? (I have no apple care) Thank you in advance.

Computer Shutting Down and Magsafe not working?

Hey guys my computer is a MacBook Pro (13-inch, Mid 2010) and i have had Magsafe issues with it since 6 months after i bought it. I had it sent in to apple and they said that they had replaced the magsafe within the computer (i am assuming that they replaced the magsafe board). Recently my computer has not been recognizing any connection when the magsafe is plugged in. No lights and the battery will not charge. It takes several tries +20 to get it to recognize the magsafe and start charging. The adapter is NOT the problem and neither is the battery. I have also already performed a System Management Controller reset (SMC) as the symptoms seemed to follow this common problem. This has not fixed it. Now my computer is shutting down randomly (it seems to do this when under light to medium cpu load or when moving) however, this is hard to tell as it has only happened three times. The computer only seems to shut down when the magsafe is connected and recognized (either red or green light). When it shuts down i can hear the HDD needle "park" rather abruptly/loud as an audible CLICK can be heard. Upon reboot, the computer will again refuse to recognize that the magsafe is plugged in. Again, no lights on the magsafe connector, and the battery will not charge. This issue could brick my macbook unless i fix it soon. Please any help??? I really hope that nothing is wrong with the logicboard as they can run upwards of $600 to replace. PLEASE HELP MEH!!!
Some additional background: I had sent in my macbook to apple 3 times already through futureshop while under warranty. The problem was that the magsafe only seemed to work while plugged in with the cord running away from the user. They sent it back twice while only swapping chargers... of which i knew there was no issue with. The same magsafe problem was there. The third time is when they finally swapped out the magsafe in the computer. My one year warranty is now over and it has been about 8 months since i got my computer back since being repaired last time. I have no applecare warranty. Is there any way that this could be fixed under warranty??? Is there some kind of apple replacement warranty if something has been sent in so many times with the same problem??? Thanks and sorry for so much writing...

Hi there
I just posted a quite similar issue today.
My solution was to simply run Disc utility and see whether it finds any problems/errors. It did find an error and after booting to Recovery partition and running Disc utility from there, I let it repair the volume.
Until now, no more random crashes on moving.
Hope this helps you too

My MacBook Pro 13'' shuts down randomly while connected to the power cord.

Alright, so my Mac is shutting down while being connected to the power cord. Though, when I unplugged it, it runs just fine.
I've read up on the other random shut downs but they seem to be different in my case. I was only surfing youtuve on Firefox, granted I had a few other tabs open but they weren't doing anything that would run the computer hot, and it shut down out of no where. The battery was full and it was still connected to my power cable. The screen went blank and the computer was completely off. I noticed that the light on the plug in wasn't on and switch the outlet that the computer was plugged into and replugged it into my computer. The light came on and after about three or so times of pressing the power on button it came back to life. Though, it stayed on the start up, white apple page and just spun. After a while it looked as if it was about to go to my password page but it shut down after gently moving the computer. The power cable light went off once again. I unplugged it and replugged it into my computer but the light would not come back on. After just removing the cord and pushing the button a few times my computer came back to life and I logged in as normal except for the fact that after it came back on the date and time was reset and several applications needed permissions. It also randomly logged me out of my Facetime account as well.
All in all I was wondering if anyone else had a similar problem and know what's going on or if this is new. Could it be some kind of spark in the power cable from a broken wire that made my computer shut down or is it something attacking my computer?

Please make a Genius Appointment and take it in for service.

Computer shuts down during render/prerender

This was not my original problem but it has occured before and I know it will occur again.
My computer shuts down for no reason when I try to render or prerender video in Adobe Premiere Pro CS4. From what I can tell it is a general issue with premiere that I am having. I have tried multiple video formats, multiple video lengths, and multiple rendering options and I am still getting random shut downs during rendering.
Here are some specs for my computer which is a laptop:
OS: Windows 7 Ultimate (64 bit OS)
Proccessor: Intel Core 2 Duo @ 3.0 ghz
Ram: 8 gigs of it
Video: Nvidia Geforce 9600M GT
1 Hard Drive w/ 280 gb of space
As a recap.... My exact problem is that during the rendering or pre rendering proccess my computer simply shuts down as in it turns off.
I can also add that the computer does act strangely leading me to believe that theres some hardware or software incompatibility. While it is rendering I can hear the CPU fan pick up which is usually normal for any rendering application but what I noticed was that it doesnt stop speeding up. Its like if it was going into an overload and I can confirm that at its peak, the computer shuts down.
To add troubles... whenever I pre render any video and it succesfully renders.... Premeire will hang up really really bad if I try to play the pre rendered preview. In otherwords when you preview a video that it pre rendered it usually plays smooth and everything is fine. After I pre render something though and play it I can tell its locking up because the timeline bar is really jumpy and the video playback skips also.
This is the problem I would really love fixed. I usually have to button smash my keyboard until I lock premiere up and then once it unfreezes itself i can preview my work smoothly. This is however like a good 5 mins of my time trying to get the preview to play smoothly though so its really hurting how fast I can work.
If anyone can help me out I would greatly appreciate it. I will be trying to run the same stuff on my older laptop and observe the results. I personally think CS4 is incompatible with windows 7.

Video: Nvidia Geforce 9600M GT
If you have a recent nVidia driver installed, you might want to check to see if you have either of these two modules loaded - check in the nVidia console:
PhysX, or 3D Stereovision. If you have them, definitely disable 3D Stereo, and test. If no improvement, disble PhysX and test.
Also, try adjusting your Hardware Acceleration. If Max, set to Min and test. If Min, set to Max and test. If either helps, try incrementing up, or down, until it no longer helps.
Last, check your OpenGL settings. If ON, turn OFF. If OFF, turn ON.
It appears that you have a laptop. Is that correct?
Good luck,

IMac 20" shutting down randomly

Hey folks,
My iMac has been shutting down randomly a couple of times a day. It's been happening ever since I purchased the machine (April, 2008) and more often when its warmer (I live in Los Angeles). I've taken the computer in for a check up and the Genius Bar said that they couldn't replicate the problem. They had the computer over over a week.
Now that it's getting warmer these days, I'm finding my iMac shutting down more often. Does anyone else have this problem? Any luck with the Genius Bar?
I've seen my hard drive reach 65ºC and the rest of the components in the high 50's, low 60's. As a temporary solution, I'm running smc fan control to try to keep things cool.
Thanks!

Hi, a couple of questions -> Applecare? Have you contacted Apple Customer Relations?
I would also document everything you do from when you Start Up, times etc., Apps etc.
If you have a digital camera with movie, load it up with a large memory card & set it on a table near your computer & run it until you capture the shut down..After that Apple will take action...
Recently my 2 laptops MBPro 14mths old/MB 7 months old - Both had issues, after a few tests via AppleHelp still no joy - Apple replaced both with the latest models...
If the Genius can't help - Ask for the Manager...
