Mac just powered down and now unable to power back up

My Mac just powered off. No warning. Unplugged the Mac and moved to a new outlet and still no response. Is there anything else to check. I even replaced batteries in the keyboard and mouse, but no surprise that didn't help. Any suggestions or do I need to take the machine in?

Hello, I can't turn my iphone 4s on, it just broke down and now there's just the black screen with the apple logo on it. So I connected it to itunes and tried to restore it, but than always the errors 1603 & 1611 appeared! please help me!!

You may have a faulty USB cable. Try another.
Make sure you are following the instructions in this procedure to the letter. Here they are, with emphasis on some easily overlooked requirements:
Disconnect the USB cable from the iPhone, but leave the other end of the cable connected to your computer's USB port.
Turn off the device: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the device to turn off.If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release only the Sleep/Wake button.
Continue pressing and holding the Home button while you reconnect the USB cable to the device. The device should turn on.Note: If you see the "low battery" screen, let the device charge for at least ten minutes to ensure that the battery has some charge, and then start with step 2 again.
Continue holding the Home button until you see the "Connect to iTunes" screen. When this screen appears (iTunes icon and USB connector) release the Home button.
If necessary, open iTunes. You should see the "recovery mode" alert ("iTunes has detected a phone in recovery mode").
Use iTunes to restore the iPhone.
If you do not see the "Connect to iTunes" screen, try these steps again. If you see the "Connect to iTunes" screen but the device does not appear in iTunes, see this article and its related links.
Select the device in iTunes and choose "restore from backup".
If you still can't get it to work, you have done all you can and only Apple will be able to help.

My mac just shut down and it wont turn on! it only make a noice for 3 secods an stops and keeps doing the seme ting by it self.
and im runing lion on it.

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 4 just shut off and now will not turn back on.

My Iphone 4 just shut off and now will not turn back on. I was listening to music, it started to make a static sound then shut off and will not turn back on. What do I do?

Battery dead?
Plug it into the charger that came with the iPhone and plug that into a known good wall outlet. Leave it plugged in for 20 minutes. Then while still plugged in reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

My Mac randomly just turned off and now it wont turn back on, the charger light is faintly flashing green and amber?!?!

My mac randomly turned off last night had some trouble with an uncertified usb cable that I was trying to charge my iphone 5S with but it came up with that message of not being able to charge with this accessory or something so i plugged it into my mac thinking it was my plug to charge my phone then like 5 mins later my mac just randomly turns off and it did have like 90% batt but i still plugged it back in thinking it was just being wierd but then i pressed the power button after it being plugged into my mac and it wouldnt even turn on no fan starts or anything and now the colour of the charger light is very faint and is almost flickering between green and amber, please help me out I dont want to pay loads of money for something that I might be able to fix?!?!?!

I actually just fixed it. Here is what to do;
1. Unplug everything from your computer.
2. Take off the bottom of your MacBook / Pro / Air. (There are usually 3 screws that are longer than the rest near the vent, remember where they go.)
3. Carefully unplug the battery from the logic board.
4. Wait 10 seconds.
5. Plug the battery back into the logic board.
6. Put the bottom cover back on.
7. Reboot the computer holding the "Option" key.
It's not exactly what I did but it should work. If it doesn't work, what I really did was unplug the battery and then plugged my charger into the computer, the fans started spinning and then it shut off again. Then I plugged the battery back in, put the bottom on (with no screws), and tried booting up again. The Apple chime played and then the computer shut off. So I tried booting again holding the "Option" key and it booted up like normal. I then restarted my computer to make sure it is back to normal and it is.
Wow what a relief. I was really scared there for a minute.
*And for everyones information I was using a Belkin USB cable but it had never done that before.

Mac mini slowed down and now will not start up

Help!
I couple days ago i noticed my mac was running a bit slower than usual but I just ignored it since I brought it home for the holidays and thought it might just be the internet connection. Then, yesterday, I turned it on in the morning and it was running so slow that it would take up to 10 minutes just to open any window. TODAY, i turned it on again to try to solve the problem after being unsuccessful yesterday, and now the fan starts blowing really loud as soon as i turn it on as if it were hot (i don't know, im not very smart with computers) and it will not load past the first grey screen or the second blue one.
Any ideas on how to solve this problem? Also, if it matters, i'm not sure what my 'OS' is and since i can't turn my mac on i can't find out what it is at the moment...
Thanks for any suggestions!

Thanks for the info about having wrongly applied the PMU reset to your Intel Mini. That will account for the fan running full blast. Only known (cheap) fix is to apply the correct SMC reset.
http://support.apple.com/kb/HT3964?viewlocale=en_US
(The Mini's reset procedure is at the very end of that link.)
If that fixes the fan, then we have to consider that your original problem had something to do with the hard drive. Either the hard drive was too full, or else it was starting to fail and needed to re-read sectors -- which would account for things getting very slow.
Do you have any recollection of how full the drive was? Any warning messages?
To check for HardDrive failure or file system corruption, typically one would startup the Mini from the install disc that shipped with it and run DiskUtility from the Utilities menu at the top of the screen. But it seems you can't get your hands on that disc -- and you pretty much need the kind of disc that shipped with your model of Mini.

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!!!

HT4061 my phone just went off and now will not turn back on... will not connet to itunes to download or backup

ok phone worked one minute and then just cut off and has not come back on ..... no water damage no extreme temperatures.... will not sync with itunes account ... nothing ... any suggestions

try putting it on recovery mode or dfu mode or http://support.apple.com/kb/HT1808 or try to connect the iphone to your computer while holding the home button, if this doeant work more likely your battery is totally dead try doing a hard reset while the iphone is connected to the usb port by pressing the home button and sleep/wake button at same time and wait for the apple to appear and release the sleep wake button usually this works ... restore the iphone..... if it still continueds to shut down your logic board or the battery is already bad

While using iPhone 5 as tether, downloaded the latest update. phone shutdown in preparation for receiving upgrade connection was lost and now won't power back up. suggestions

While using my iPhone 5 as my personal hotspot. I downloaded the latest update thru connection to my laptop. During the process of installing update to my phone it shutdown. Now the phone will not power back up, instead it will only show the Apple icon then shows the icon of the USB cord needing to be connected to iTunes. Suggestions

That indicates that you phone is in recovery mode and needs to be connected to iTunes on your computer to be restored.

Just powered down and moved my iMac and when powered back up all it says is no bootable disc-please insert disc and hit any key......what do I do?

when starting up my iMac (had just moved it from one room to another, was working fine) it only shows on the screen "no bootable disc...please insert disc and hit any key".....what do I do?

That sounds like a message from a DOS-based computer. A Mac would just show a folder with a question mark, unless they've changed things recently. Do you have a BootCamp partition?
Try holding down the option key immediately after the Chime. You should go into the startup manager and it will show all bootable drives. Pick yours, then go into System Preferences and set your startup disk.
Next would be to try a Safe Boot by holding down the shift key right after the chime until you see the gray screen. It will take a while to boot up as it is running some disk checks.

My iphone just shut down and now i cannot turn it on, any suggestions?

my iPhone will not turn on, is there anything I can do?

Thank you! I tried this after I posted my question and it worked. I also tried this when my phone stopped working; however, my power button is jammed so I think it took a few tries to recognize.
