HT1338 my macbook air continuously turns itself off and on again for no apparent reason- despite having full battery... What is wrong with it?

As of recently my macbook air continuously turns on and off.
Sometimes it does not turn on at all. When it does turn on, after a few minutes it comes up with the shut down options and unless I press cancel it turns off. Occasionally when turning on it only gets as far as the startup sound then turns off again- occasionally in a continuous loop.
Any ideas?
HELP!

I think you might get a new phone instead of repairing it as it takes time and you said the repairing center is far from your living place

New to Macbook Air. Screen suddenly expands to 4-500% for no apparent reason. Have to use back arrow to return but lose what I've been typing. What am I doing to cause this?

Next time you want to put your iMac screen to sleep, try switching off the Magic Mouse, wait for the notification to come up on the screen telling you the Magic Mouse has been disconnected, wait for it to disappear then press the keyboard shortcut to put the screen to sleep. See if that helps and we'll go from there. If that doesn't help, can you just say wether the screen always turns back on the same time every time?
Hope that helps

I have followed the step-by-step instructions to try and fix my iPod mini, but nothing is working. It continually turns itself off and on, and in and out of disk mode. How do I fix this? please help!

I havent used my iPod Mini in about a year, but last time I was on it worked. I have tried almost everything.

Sounds like your battery is failing. If you have AppleCare, make Genius reservation and take to Apple for resolution. If no coverage, you can still take to Apple Store for free quick battery diagnostic testing.

Nano keeps turning itself off and on again (only to apple)

So I went to charge my nano and when I did so it froze, so I reset it and ever since it wont come on properly, it gets to the apple screen (no backlight) then the backlight comes on, then EVERYTHING goes blank and then it starts again. (this behaviour only when attached via USB) If I turn it on unplugged I get the apple logo (no backlight) and If I press select it lights up for a split second then goes of...
What the ????

try to reset it
I know it might not work the first time
but if u keep trying it might start working
after restoring and reseting my nano like a billion times
mine started to work again
I guess all u can do is go to apple if this does not work
or complain and hope that apple will release a new version of soft
if more ppl post about this problem i sure apple will resolve it like the cracked screen problem

My macbook air froze, after switching off and on again it started making a beeping noise. the screen is black. please help :(

How do I stop the beeping sound on my Mac book air? The screen is black.

What beeping sequence are you getting?
1 beep - No RAM
2 beep - Incompatible RAM
3 beep - Faulty RAM
4 beep - No good boot image in ROM
5 beep - Failed processor
With an Air you will have to take it to an Apple store genius bar to address any of those issues.

My iPhone is continually turning itself on and off, how do I solve?

It's turned itself off and then when I tried to turn it back on it continually turns itself n and off! How do I solve it?

Restore the phone in iTunes, first using a backup, and if needed as a new iPhone without using a backup. If this still happens after restoring as new, there is a hardware problem than needs evaluation by Apple or whoever provides iPhone service in your country.

My I phone5c has turned itself off and won't turn back on,have only had it 3 weeks,any ideas anyone?

My iPhone 5c has turned itself off and won't turn back on, any ideas anyone?

Hey Jswalker1969,
Thanks for the question. If your iPhone is not powering on, see the following troubleshooting steps:
Will not turn on, will not turn on unless connected to power, or unexpected power off
1. 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.
2. Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion.
Learn about LCIs and corrosion.
3. Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
4. 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.
5. 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.
6. 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.
7. If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
My issue is still not resolved. What do I do next?
Contact Apple Support.

My ipad2 keeps turning itself off and On

my ipad2 keeps turning itself off and on. I can be playing a game or looking on the Internet and it will just turn off and restart all by itself. I pulled up and hooked it up to itunes on my computer but I'm not really sure what to do there either. It's so annoying, especially when it's used daily, or all day, by me or my kids and it's constantly shutting off in the middle of things.

DId the rebooting start recently after doing an iOS update or installing a game?
There could be several reasons for your iPad randomly shutting down & restarting.
Sometimes low memory (RAM) can cause the issue.
First, restart the iPad by holding down the home & sleep/wake buttons simultaneously until the Apple logo appears then let go and wait until the iPad boots up normally. This can help clear the cache & free up memory.
If that doesn't work, try a general reset:
Settings->General->Reset->Reset All Settings. You will not lose any data but will have to log back into your Wifi networks.
If the issue occurs while using a particular app, try uninstalling the app to see if it continues.
As a last resort try restoring the iPad back to factory settings. Be sure to backup your iPad first.
Use iTunes to restore your iOS device to factory settings - Apple Support
Unfortunately, it may also be that your battery is starting to fail but try the above to see if the problem persists.

Hello untech,
I see that it has been awhile since you have posted with us on the HP Forums. Please let me take a moment to say "Welcome Back".
I see that you are having an issue with the printer shutting it self off and not powering back on.
By chance do you have the printer power cable connected to a power bar/strip? If so, please try connecting the printers power cable directly to a wall outlet. Here is a document that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector.
The printer in the document is a LaserJet printer but this document is meant for HP products in general and only uses the LaserJet as an example.
I am also going to include a document for when The HP Printer Won't Turn On or Respond When the Power Button is Pressed.
If by chance the issue is not resolved after doing the steps outlined, I would then suggest calling HP's Technical Support to see about further options for you. If you are calling within North America, the number is 1-800-474-6836 and for all other regions, click here: click here.
Please feel free to write me back if you have any other questions.
I hope you have a great Monday.

Thanks for your help. I tried plugging it in but nothing happened, I actually still had battery power left. I was able to solve my problem by holding down the power and home buttons, which reset the phone and got it started again.
Thanks for trying

Try resetting your phone:
Press the sleep/wake button & home button at the same time, keep pressing until you see the Apple logo, then release.

If you have restored to factory settings and started as new, there is nothing more that you can do on your own. Make an appointment at an Apple Store and ask them for help. You might have a hardware problem and the Apple Store techs will be able to determine that.

My iPhone4s turned itself off and will not turn back on unless it is charge data all times. I need help and answers please.

My iPhone4s turned itself off and will not turn back on unless it is charged at all times. I need help and answers please.

And we would need more info. "will not turn back on unless it is charged at all times." is pretty obvious: the phone will obviously not turn on unless it is charged.
Describe your problem clearly.

Why does my 1st gen iPad always turns itself off and goes back to the screen. Whether I'm reading news, iBooks, etc, suddenly it goes off.

If that doesn't help, the battery may be dying and need replacement. See here (tap on Battery Replacement): http://support.apple.com/kb/index?page=servicefaq&geo=United_States&product=ipad
Alternately, might consider start saving for a new iPad. The newest iPad 6 should come out in the next few months. When it does, sellers will want to get rid of old inventory with good deals.
