My mac randomly cut off and it won't turn back on, what do I do?

I just bought my mac the other day and I was about to Facetime someone and it randomly cut off and it will not do anything. It wont even charge. I don't know anything about computers so I have no clue what to do. PLEEEAAASSSEEE HEELLPP!!

If it's new, then it is under warranty. Please make a Genius Appointment and take it in for service. If it is a used computer then you need to provide more information. If your battery will not take a charge, then either the charger is not working or the battery needs to be replaced or both.

My iMac G5 w/iSight (A1145) randomly shut off and now won't turn back on!!

I was using it like anyother day and it just turned off. Now it wont turn back on even with switching outlets!! HELP!!

You probably have a thermal problem. Try resetting the SMU and see if that helps. Since it's an iSight you can't take it apart to check for defective caps, but you can bring it in to have a tech do it for you.
Let us know how you make out,

My iPhone 5 just randomly shut off and it won't turn back on. What do I do?

I pulled my phone out of my pocket to check something and i hit my home button to open my phone and it wouldnt turn on. I tried the lock button and that didnt ework either. I thought my phone may have died so i tried to turn it back on and that didnt work. It had about a 40% battery and this has not occured any in the past. Please help!!!

Connect iPhone to Wall Charger for 10 minutes, it may turn ON itself. If still nothing, keep on charger and Reset, hold both home and power buttons for about 20 seconds until the iPhone begins to respond.

I was using my Ipod Touch, and it just cut off. It won't turn back on now. It won't charge. What can I do? Any suggestions?

Help! I charged my Ipod touch the other night, I was using it yesterday and it cut off. It won't turn back on now at all. I've tried to plug it in to charge, and absolutely nothing happens. Any suggestions?

Hello Christie,
With it still plugged in, try a hard reset to see if that helps. To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear. This may or may not work the first time around, so be sure to try this at least a couple of times.

Check your cable whether it is good. If it is use the wall plug to charge at least half an hour. See how it goes.

Plug it in to power for at least 15 minutes.
The, try resetting your iPhone by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.

I downloaded iOS8 on my iPod 5th generation the other day and its been completely fine and now all of a sudden my iPod has turned off and it won't turn back on, i have tried charging it but nothing is coming up, what should i do?

the other day when iOS8 came out i downloaded it onto my 5th generation iPod, it has been working perfectly fine since, now today when i left it for a couple of hours, it turned itself off and now it won't turn back on. i have tried charging it but nothing is happening. it's not out of charge because the little battery usually comes up when its charging, but the screen is completely black and nothing is happening. i have tried turning it on by both buttons and it won't work. i don't know whats wrong with it. i haven't topped it or anything, so I'm assuming its the new download as it seems to be effecting other peoples devices as well. what should i do?

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 suddenly turned off by itself and it won't turn back on, what to do?

So I was just texting with my iPhone (with 35% battery life) earlier and when I check my phone again 5 mins later, it completely turned off. So, I tried holding the sleep/lock botton on top + the Home button (for more than 10 sec) and it won't turn on.
So I tried plugging my iPhone to the wall-adapter charger and it turned on (with a 100% battery life?), but seems like all my settings have been resetted and I was advised to connect with iTunes. Then I unplugged my iPhone and plug it onto my computer to sync. I waited, the apple logo comes up and then it turns off again, logo comes up and turns off again (constantly doing that and it's not going anywhere).
Did my whole iPhone battery just died or something? I repeated the process and whenever I unplug the phone from the wall-charger, my phone completely turns off. When I plug it with my usb-to-computer, the apple logo comes up and goes. Any one can help?

Connect iPhone to Wall Charger for 10 minutes, it may turn ON itself. If still nothing, keep on charger and Reset, hold both home and power buttons for about 20 seconds until the iPhone begins to respond.

Thank you, thank you, thank you, bongzki_02 for your tip, It worked right away on my New iPod 7th Gen

Computer just turned off and now won't turn back on!!

I have an IQ770 Touchsmart and while I was out of the room, it turned itself off. Now it won't even turn back on!!! I've unplugged and replugged and it won't do anything. What could have caused it? There was no power interruption, it's plugged into a power surge protector, my other desktop is working fine. I've been working on it all day, and now it's dead! What do I do? Can anyone help me?
Thanks!!!

Ok, I've tried to plug it back in, and when the plug reaches a certain point, it pops sorta. Which tells me that it's the psu unit that's gone. This puter is only 2 years old. I've already had to send it in for a complete hard disk die, now this. It's a Touchsmart IQ770. Yes, made the mistake of getting one of the first ones. Not only that, it's Vista all the way. So, this computer is screwed both ways all the way. When it works, it's wonderful, but since it only works half the time, it's definitely not worth the money, time, headaches or worry that it entails to have. It's an expensive piece of @#*(!!!!) I do want to thank the people who tried to help me, sorta. Just put this into the next inquiry of the IQ770, It sucks!!!! Big green donkey dicks!!! Vista made it worse!!!

MY iPhone turned off and now won't turn back on

then would keep turning the light on
the it turned off and wont turn back on
i tried (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears) and non is happening ? any ideas

Standard troubleshooting...
Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
If still a problem restore with your backup.
If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
If still a problem, it's likely a hardware issue.

My ihpone turned off and it won't turn back on

i was using my ihpone and then it turned off and it cant turn back on

How low was the battery at the time it did this?
Try a Reset: Hold down the sleep and home buttons, ignore the red Off slider, wait for the Apple logo, let the buttons go.

HP Envy 32" monitor screen randomly shuts off and now won't come back one

So I've had this monitor for about two weeks. Several times it has randomly just went black. The power indicator LED is still showing it's on. My laptop still recognizes that it's connected only when I physically disconnect it from my laptop or unplug the power cord does it disconnect. Right after it happens I try switching to a different input (i had another laptop hooked up to the HDMI) and also pulling up the menu but nothing happens. I try turning it off with the power button or remote, nothing happens. Only after I unplug the power and plug it back in does the display work. ...Until this last time, it went black and no amount of unplugging and plugging back in would get it to work. It still "connects" to my laptop but there's no image, only blackness. I've mainly been using it with my lenovo thinkpad yoga via the onedock pro displayport, but when I try just HDMI with my other laptop I still get nothing. I've also tried unplugging and holding the power button for >1min like another post suggested. Any ideas? I'd hate to have to send it back.

okay so after a long wait with it being unplugged, I tried it and the display worked. i adjusted a few settings -turned off auto input selection and made DP hot plug always on (not sure what that does, but I thought I'd give it a try). Now instead of it randomly going black it randomly shows a green screen of vertical lines, and I have to unplug and wait forever before it works again. any thoughts?
