MBP Screen Turns Off Randomly - Battery Charge/Plugged In...

Two to three times per day for the last several weeks, my 201 Macbook Pro screen will just turn off. If I am using Spotify, the audio will stutter and I'll be forced to hold down the power button and turn it off and on.
Per instructions on this site, I ran the hardware test which said one RAM slot was faulty, bought a new stick, installed it, ran the test again, no more error messages but the problem persists.
Otherwise the computer runs beautifully, no issues whatsoever. I'm running OSX 10.6.8 with 8 GB of RAM.
When it comes back on I get the following panic report:

Hello,
I've got the same problem, it seems to came from faulty memory slots, not really from faulty memory sticks.
In my case, I'm using a MacBook PRO 15" Intel I7 2,66 ghz from mid 2010 with two sticks of 4go DDR3.
At first I had error messages like yours with reboots and so on ... After some weeks it gets worst : The MacBook wouldn't reboot, it plays 3 beeps with black screen instead of starting normally.
I thought that it came from the memory sticks and replace the two sticks without any result.
Lets call the two memory slot A and B (A the higher and B the lower).
I tried to start the computer with memory stick in A : OK, some error messages and reboot by day, but starting ok.
I tried to start the computer with memory stick in B : Impossible, 3 beeps and the computer wont start.
I Have repeated this test with 4 different memory sticks, the result is always the same, B is no longer working ...
I'm very disappointed, a computer like this that brakes in two years ... I'll go to my Apple Store next week, if you're intrested I'll give you the diagnostic ... and the price of the repair ...

Laptop turns off randomly when not plugged into charger

I have a 2013 Macbook Air and a few weeks ago, it started turning off randomly after a few minutes of use. It only works without turning off when it's plugged into the power.
I tried resetting the SMC various times, and the battery software update was not applicable to my device.
I'm not sure if it's a dead battery or not, because the device still charges.
I work for a magazine, and kinda need my laptop so any help would be greatly appreciated.
Thank you

Hey bbkae
Continue you troubleshooting with the article below to check the health of your battery. I would try to run hardware diagnostics on it to see if it passes the test.

Black screen/turns off random bootcamp windows 7

I have a imac 27" mid 2010 and i am using windows 7 x64 ultimate on bootcamp (3.3 and later 4.0) from snow leopard to lion, i have
recently upgraded my mac with mountain lion.
But after i did upgrade to mountain lion a day later my screen in bootcamp goes black/turns off. I can sometimes hear the sounds when it happens.
The black screen/turn off, is also randomly so its not happening when i do something or opening something. So after a few black-outs i started to get fustrated and i surfed the web for solutions (Option + Alt + P + R), disconnect power cord wait 10 seconds and reconnect, install/uninstall new drivers, reinstalling windows. reinstalling mountain lion and windows but the problem is stil there.
But when using mountain lion i dont have any problems everything works fine.
I think that mountain lion has changed something to the firmware or bios of the system, or changed something to bootcamp?
I really dont know, the only thing i know is i cant use windows as i normally did, and my boss isnt happy when i dont finish my work.
I really need some answers and solutions.
Thanks

Same problem occuring for me, although Windows 7 boots fine in safe mode but when booting in regular mode after the lauch screen it goes black and turns off. Funny thing is that mountain lion didn't seem to be the problem for me instead I believe windows updated it's software for me and then it started happening. Im going to try and reformat partition reinstall windows 7.
oh BTW I'm on Macbook Pro x Retina Display.

IMac screen turns off randomly?

Hello
I'm new to this, so sorry if I haven't posted this in the right place or anything
Basically, my iMac screen just turns off randomly, like once a week. It only happens when I come off sleep/screensaver like 2 minutes after, then I have to press the iMac button
Anyone else have this problem, or know how I can fix it?
Thanks!

Hello Heather & welcome to he forums!
You did pretty good for the first time... & this is a pretty friendly place.
Open console in Applications>Utilities, check the system log for the date/time of the last problem & the restart right after that for clues.

How do I prevent my iPhone 4 from turning off randomly while charging and connected to MacBook Air?

My iPhone 4 randomly powers down while charging via USB to my MacBook Air. This has happened twice while I was sleeping and always makes for a great morning. Here's what happens:
I keep my iPhone 4 ON and connect it to my MacBook Air - battery charge level is typically around 20%
I keep my MacBook Air connected to AC power
I go to sleep
I wake up without my alarm and find my iPhone is now OFF
I turn it on and find the charge level to be at 100%
It seems to only happen when connected to the MacBook Air. Has anyone else seen this or have a potential remedy to this issue?

Try the power related troubleshooting suggestions in this Apple article -> iPhone: Hardware troubleshooting
If that doesn't work, have a Genius take a look at it.

Screen turning off randomly, cannot turn back on. potential disaster for live music i'm doing!

screen goes black, laptop seems to have not turned off but nothing can turn the screen on. seems fine after a reboot but problem recurs at some random future inconvenient point in time. problem is annoyingly inconsistent - it will occur at random (no discoverable software or hardware conjunctions), sometimes around once weekly, sometimes less frequently. have already had it in a mac repair, said they fixed it, something to do with graphics card firmware. not so. same issue. currently in touch with support but in frustratingly slow red tape processes. VERY curious to find if ANYONE has experienced this issue. it seems very unlikely that i am the only macbook pro user on earth that this happens to......i perform live music with this laptop as part of my set-up - and am actively refusing shows at present until this is resolved!!!

thank you very much for your reply.
can you please just clarify exactly what you mean by "replaced my HDD to SSD" - you mean changing your hard drive to the solid state kind? how long ago did you make the change and thus how long now without the issue? was it also happening to you irregularly (it might be a month or two that it won't happen for, and then more frequently...) - many thanks for any info......

Early 2008 MBP screen turns off/on (not NVidia issue)

My MBP is an early 2008 A1260 15" and the screen suddenly turns off and on. Originally I thought it was the NVidia issue but that doesn't seem to be the case because I can hook up an external monitor and get video. I took it apart to check any loose video cables on both the logic board or behind the screen itself and everything seemed intact. I even pushed everything firmly in to make sure the connections were making good contact. The backlight also lights up but without any image so the inverter is not to blame either. Then as I figure it's simply the LCD that has gone bad and i'm using my comp through the external monitor the screen suddenly turns back on and works. Later shuts off and back on. This makes me think it's a faulty cable however everything is connected properly and there were no signs of damage to the video cable.
Any suggestions as to what to check or this could be? I don't want to pay nearly $150 to replace the LCD screen if that's not it. :/

Allow me to elaborate the situation...
Taking in to Apple = $350
Purchasing a new display and replacing it myself = $150
New video cable = $30
Taking it to Apple = No.
I can fix computers on my own but I am a bit stuck on this slightly odd situation so I would greatly appreciate any replies to not include the response, "Take it in to Apple."
I appreciate the suggestion but that's not going to happen after I already took it in thinking it was the NVidia issue and there found it was a display problem.
You're right that it seems it's a component that's failing but that's why I am asking, which other components should I check? Any other similar issues? Etc.
Thank you

MBP screen turns off after opening

It happens every now and then that the display light of my MBP late 2011 turns off right after opening it and I only can get it back by hitting F1 and F2. Any ideas??
Thx

Ipod Touch White Screen - Turned Off - Wouldn't charge or turn on

While I was happily playing one of the games on my Ipod Touch 2nd Gen, a white screen came out, with the games sound still present, but soon after the ipod touch just blanked out and turned itself off. I thought this was due to the battery running out of charge, so I tried charging it but it doesn't work. Even itunes isn't recognizing my ipod touch when I connect it to the macbook.
I tried the reset process but it doesn't work, and the hard reset as well as suggested by those people who experienced the same white screen problem, but still nothing happened.
Since the last week, the battery started not to hold charge even when I had just left the ipod sitting on my table for a day or two without any music or applications on.
This is the 2nd time this had happened, the first time my warranty was still valid, but 7 months after having it fixed (no longer under warranty now), it happened again, but this time it is worse as it wouldn't respond as well (the first time it just didn't hold charge).
Anyone know any other solutions apart from bringing it to the Apple Store? I wouldn't want to buy another ipod just yet since this is a 32GB one..hmm
Thanks for your help in advance

Screen turns off randomly

Hi there,
Thanks in advance for the input.
This is my MBP specifications:
15 Inch mid 2010
Processor 2.66 GHz Intel Core i7
Memory 4 GB 1067 MHz DDR3
Graphics NVIDIA GeForce GT 330M 512 MB
Software Mac OS X Lion 10.7.2 (11C74) (Installed it yesterday, problem keept happening with Snow Leopard)
500 GB SATA HDD
4 GB RAM
It's been happening for quite a while, at first it was just while I was browsing the internet. Then it just happened randomly. The sreen is completely OFF, and if I'm playing music or anything with sound it starts looping, the only way to stop it id by pushing the ON/OFF button until it shuts off, and turn it ON again. When I turn it on it prompts me to file a report and it says the computer had to be shut down because of a problem. I send the report every time, but have no idea if it is a problem with software or hardware. I don't think it is overheating, it just does it randomly, and a few times right away again after restarting.
Please help? I'm afraid this would happen in the middle of my work.
Does anyone else have this problem? How do I know what the real problem is, and how do I solve it?
Thanks a bunch in advance.

Welp, that didn't work out either... I put it on deep sleep a couple times, yet the screen goes out while I'm working actively on the computer, no matter what. Just last night, I put it on deep sleep, and it did it again, I woke up in the morning with the ligths of the keyboard on and there was no way of waking it up I even waited the 15-30 secs. for it to do, and didn't come back to life. Shut it down with the power button, turned it on again, prompted me to file the report, once again I did, and the creen went off two other times already since then. One of them while I was switching between chat conversations on skype (not on video calls or anything). This is getting scary.
I found a couple threads here that were close to my problem, although my MBP has a different video card, I'll give this a try, just in case. I already contacted a technician that'll take a look at it, since I'm not in the US and access to an apple store here is nearly impossible, that and the 1 year warranty is gone already.
This seems to help in other cases:

This seemed to be the issue for other MBP's manufactured in 2007-8

Wish me luck and other options please?!

Why is screen turning off randomly?

For some reson or another, My Macbook Pro will be running fine, and depending on my actions (mostly using FCPX or Preview) the screen will shut off and go completely black, not dim cuz I tryied the brightness keys they do nothing. and the keyboard back light stays on so I know that the computer is still on. I don't understand what to do or how to do it. I have already been to an Apple store or a HD replacement I don't want to have to go back but if I do I do. I'm looking for some quick help because this is my school computer and I need to have it running with out bugs and such. Please help thanks in advance.

Thta does not sound like there is any software tweak that will make your screen work properly.
Homework is to reset the PRAM and do an SMC reset.
Then back to the store.

MBP turning off randomly while on battery

So my MBP keeps turning off randomly while I'm using battery, first few times it happened I thought it had just got to hot and turned off because of that. But after it happend a few times i noticed that its not even hot to the touch. Its happening what ever i am doing even when I have very low cpu usage like listening to i tunes, or just watching a movie.
Any ideas what it could be?
Thanks for any help you guys can give.

I have the same problem. It is most likely the battery has become faulty or possibly damaged. Best to replace the battery or if you can call one of the genius' at the mac store.

Has anyone else experience their iPhone 5 turning off at a high percentage and turns off randomly turning back on with the red battery needing it to be plugged in?

Have had my iPhone 5 for almost a year now, love it, but lately it has been turning off randomly with percentage rates of 50% or above and when I go back to turn it back on it has the dead battery sign on the screen. I am trying to figure out if its hardware issuse or if its the battery itself. Just need suggestions on what to do? Took it in and they want me to restore it but I want to try something else before I wipe it clean.

1) Try This...
Close All Open Apps... Sign Out of your Account... Perform a Reset... Try again...
Reset ( No Data will be Lost )
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons...
2) Also consider Deleting any Apps you have Purchased / Downloaded but you now never use...
3) Make sure you have the Latest Version of iTunes (v11) Installed on your computer
iTunes free download from www.itunes.com/download
Then...
Connect to iTunes on the computer you usually Sync with and Restore

Iphone 4 turns off randomly and unable to turn it on without charger

iphone 4 turns off randomly and unable to turn it on without connecting to charger or PC

Hey Tiffy6996!
I have an article here for you that describes this issue and can help you troubleshoot the issue a little further:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/ts2802
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks for coming to the Apple Support Communities!
Cheers,
Braden

Iphone 4 turns off randomly and won't turn back on unless it's plugged in

Iphone 4 turns off randomly and won't turn back on unless it's plugged in.
Has anyone had this problem?
If I leave the phone (thus not doing anything to it) for an extended period of time say 2 hrs. It will have turned off and you can't turn it back on unless you plug it in, but it's got heaps of "Battery" left.
Ever so often it will turn off randomly as well, and can't turn it on again.

If your iPhone is powering off, this is not normal.
Try restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup. If no change after doing so, your iPhone has a hardware problem. The iPhone includes a one year warranty.
