Macbook just randomly turns off

i had at least 50% of battery left and working in photoshop and the computer will just turn off- no power down, no warning, etc... i can have 70%+ and it will do this. it just turns off and i press the power button and it starts up and i plug it in to avoid this. and of course, all my work is gone unless it was saved prior to...
any ideas on this problem?

It sounds like it could be overheating..
Make sure that your fans are working(air is coming from the vent), the vent is not obstructed, the vent is clean.
I use SMC fan control and will occasionally boost the fan speed if I feel like the computer is heating up and the fan isn't responding fast enough.

My iPhone 3gs just randomly turned off and won't turn back on

I was just using my phone, and nothing happened. As of lately picture mail, and videos have been sending as a text message to other iPhone users even while connected to wifi. My phone just randomly turned off and won't turn back on. I just got it in July so its not very old and I have the hard protection case on it. Is there any way that I can reset it or something?

Hold the home and power button down at the same time.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My iPhone 3gs was charged completely and just randomly turned off today. The screen is blank and the phone does not respond to a charger or the computer. Is it broken or fixable?

Why does my macbook keep randomly turning off ?

Hello everyone I am new to the forums. I have a mid-2010 macbook pro that I purchased brand new in January 2011. Last September I noticed that my battery kept dying extremely quick and that it had the condition to replace now. Me trying to take the cheap way out I decided to purchase the battery myself and install it since I am not under the applecare warranty and apple quoted me for about $300 - $500 I believe to do it. The first week or so after I changed the battery my laptop was back to normal. Since then it randomly turns off, still says the battery needs to be replaced now, and also sometimes my battery percentage shows 0% and charging. I really want to know what's wrong with it..Thanks in advance for the help!

Have you reset the SMC?

My macbook keeps randomly turning off.

My macbook keeps randomly shutting off. It is no longer under warranty. I've read all of these discussions from people with similar issues and I've tried some of the things that seemed logical. it's a late 2007 MacBook. I bought it used from a friend and they never had this issue. It was wiped clean and when I got it, after about 5 LONG uses, it randomly shut down once. I installed Snow Leopard, updated to 10.6.8, then the problem started. The fan seems to be running fine. The problem occurs weather it's plugged in or not, so I'm pretty positive it's not the battery. I've done the PRAM reset and the SMC reset.. I also took the computer apart and cleaned it. Performed the SMC reset again and it seems to be working for right now. Hopefully that's all it needed but if the problem continues does anyone have any suggestions on what it may be? Thanks.

Resetting the SMC of an Intel-based portable Mac with a battery you should not remove on your own
Note: This will not delete any data.
The SMC is responsible for controlling various system functions. None of your data will be deleted by resetting the SMC.
Shut down the computer by going to Apple () > Shut Down…
Select Shut Down or allow the computer to shut down automatically.
Plug in the MagSafe power adapter into a power source and then connect it to your Mac if you have not already done so.
On the built-in keyboard, press the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
Release the (left side) Shift (⇧), Control (⌃), and Option (⌥) keys and the Power Button at the same time.
I hope I answered your question.

Iphone 4s won't turn on. broken lock button. It just randomly turned off and won't turn back on. Can't go to apple store because going on vacation. Please help

iPhone 4ws won't turn on. I have a broken lock button. It just randmoly turned off and won't turn on. I can't go to the apple store because I'm going on vacation. Someone please help

Your phone is broken; there's no magic solution for you. You can try plugging it in to wall power and see if this turns the phone on, but if it doesn't, you can either go on vacation without your iPhone, or make the time to visit the Apple store before you leave.

Iphone 4 does not turn on? just randomly turned off and doesnt turn on!HELP

I just got my iphone 3 days ago, and it did same problem it did not turn on when i pressed power button. The phone was on but the screen did not turn on (it still vibrate when i turned the silent button and made charging sound when plugged in charger). Today, Im having the same problem. When i got it, it was on 4.02 now its on 4.1. I also tried holding power and home button for over 1min.... nothing worked. What should i do?
If i replace it will i get refurbished one? I just got it only 3 days old. I surely do not want refurbished.

HI,
No on the refurbished issue. You purchased a new iPhone, if you return it, it should be new.
Since you have only had this iPhone for 3 days... go here for help.

Computer randomely turns off-Not over heating

So, my laptop will just randomely turn off. I took it in thinking it may be a hardware problem. Supposedly everything checked out fine and they said it was my OS. So I oreded the recovery disks and reformated. It ran fine off the disks until it came to the point where it had to finish the recovery via the hard drive. Now that it is running off the hard drive it started randomely turning off again. Since the OS hasn't even been fully restored to the computer I can't even run the computer in safe mode.
Is it my hard drive which was said to be fine? Or could it be something else? Oh, and I don't believe it is overheating because it won't stay on for more than 5 mintues and sometimes not any longer than 1.

First and foremost, make sure you are on 1500VA UPS. Second, that there is nothing on the same circuit that would draw or interfere, best if nothing else is on the same breaker.
Summer storms, we've been racked so hard the house shook and everything I have is on UPS - TV and even most lights. But sometimes it is possible to have a "power event" that you won't yourself see or notice but enough to affect a computer. Not that it was what caused this, but a UPS is good investment to protect your modems, along with computer equipment. And never have to reset the VCR again hopefully.

Randomly turning off

I just got the new macbook pro about a week ago. Today I noticed some problems during use. It seems like the hard drive was randomly turning off or restarting? It would come back on seconds later but it restarted the internet and the screen went black.
Has anyone else had this problem and know whats wrong? How do I fix it?

Welcome to Apple Discussions!
Since I think you are still in the first 14 days of ownership, I would bring this to Apple's attention. You might have a faulty machine, and if so, they would likely give you a replacement. But you need to do this in the first 14 days of ownership.
Good luck!

I upgraded my iPad (first gen) to iOS 5.1 and now it will randomly turn off. How can I fix this?

Thread title pretty much says it all.
Shortly after upgrading to iOS 5.1, my 1st gen iPad started randomly turning off when I wasn't using it.
-This has been occuring for over a month now.
-It has not yet turned off while I'm actually using it, only after I've left it along for awhile
-If I leave it plugged in, it doesn't turn off
-I have trouble turning it back on after this occurs. (I have to press/hold the button several times before it will finally turn on)
-I've noticed that a lot of the time when I turn it back on, it will initially (for a second or two) show a battery % that is lower than what it actually is (ex. it will show 72% when I turn it on but then jump up to 90% after a second or two)
Seems to me like it's something related to iOS 5.1 that my iPad doesn't like, likely a batter issue. Although having trouble turning it back on would lead me to believe it might be something more. It is an iPad 1 so maybe it's just getting up there in mileage.
Any suggestions on what to do? I neglected to take any backups. Unless someone gives me other input, I'm planning on taking a backup of my current iPad and then restoring to factory settings just to see if that will solve this issue. Although that's going to be a pain in the butt to get all my apps and everything back. If I restore to factory settings, is there any way I can "upgrade" the to iOS 5.0 (or anything below the latest)?

No, you haven't lost anything. Simply sign into your iTunes account on the computer.
As for the device not syncing, what specially happens when you try to sync?

30 GB ipod randomly turns off.

I received a 30 GB ipod as a Christmas gift. At first it worked fine but a couple days ago it began to randomly turn off. I can turn it back on again but it continues to turn off on its own. Any suggestions ?

My 30 GB did this after I had added some music that I didn't purchase from the iTunes Store. Is this the case for you? Do you notice the iPod turning off when your listening to music that wasn't purchased from iTunes? If so, I just deleted the songs from the playlist and it never happened again. ~.~
