Your post is not clear. If you have no plan, were you using it as an iPod Touch? Did you try to restore and activate it again?

I have tried resetting PRAM [option]+[command]+[P]+[R],

I have changed the RAM
Nothing seems to make a difference.
Should I resort to the 7mins oven treatment ?
Not sure what to do

Thanks for your replay Ogel
1) Safe boot doesn't work
2) Reset the NVRAM / PRAM doesn't work
3) Start up your Mac while holding the C key doesn't work
The DVD I manage to enter is immediately ejected
On each boot the grey screen lasts barely two seconds before the MBP switches itself off

My ipad will not charge up. it just shows the red battery signal and then switches off

my ipad will not charge up. it just shows the red battery signal and then switches off. The same charger succesfully charges other idas so i know it is no the charger that is faulty.Any suggestions

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

In rare instances when using the Camera Connection Kit, you may notice that iPad does not charge after using the Camera Connection Kit. Disconnecting and reconnecting the iPad from the charger will resolve this issue.

NO power on my MacbookPro: it all started with Battery of my MacBook Pro saying it was not charging (even if the pro was plugged) and it then switched off and now wont turn back on. There is no light on the magsafe and no startup noises at all.

If you have Apple Care or your computer is still under warranty, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Hi Paula2808,
I’m sorry you are having trouble starting up your iMac, that must be quite frustrating. There are some troubleshooting steps I would suggest in order to get you up and running again.
First I suggest using the steps in this article for the Apple logo appearing -

If things still are not working correctly, you may want to continue with the steps in this article -

I have an iMac that won't boot up. I've read all posts on this subject to no avail. When power is switched on, it chimes, Apple logo appears, spinning wheel, then loading bar starts to fill. It gets to about 25% then switches off! Help please!

iMac that won't boot up! When power is switched on it chimes, Apple logo appears, then loading bar, then spinning wheel. Bar seems to load up and gets to around 25%, then reverts to the start again, gets to about 20% on the bar and then switches itself off leaving a black screen. Tried all the remedies on internet with no avail so would welcome some advice other than binning what is a relatively new computer. Earliest appointment Apple could offer was Thursday 17th, really useful for a business user _ not impressed,

You've probably tried this, but will it Safe Boot? Restart holding down the Shift key until you see the grey progress bar. You'll need to input your admin password during bootup. If it will boot you can then try to eject the disk using the various suggestions here that you haven't tried already:

Ipod touch keeps getting apple symbol then switches off.

I wonder if any one can help me I have a 32gb ipod touch, I have had it about 1 1/2 years so it is out of garantee now. IT was working fine until a few days ago when it started to behave strangley. I was checking my emails when the screen went. it then went to the apple logo screen and switched off. If I plugged in to computer the computer would recognise it and it would start working again. It was happening about once a day. Today it has got a lot worse. It keeps going to the apple logo screen frequently, some times it is switching off other times the screen goes gray and then white and stays stuck on a white screen and flickers. IF I do the reset by holding both buttons and conect to computer the computer recognises it and it starts working again and I can use the ipod touch but only for about 10 minutes then it does this again. I have tried updating the software version on my ipod touch today and it updated successfully but has made no difference to the problem. What is causing this problem and what can I do to fix it.

it is showing that the battery is fully charged. But may be its the battery going.It works fine when plugged in and it works for a bit when not plugged in then it does this strange behaviour. Of going to the apple icon screen and switching off. Now it just switches on/off on/off continually. When I plug it back in to computer it seems to sort its self out and starts working again. and will work for a bit unplugged before. starting the same strange behavior again. Does any have any other advice or sugestions as to what might be be the problem and how to fix it
thanks

Changed RAM in Macbook Pro now the Apple logo appears then switches off

Hi all,
I hope someone can offer me some assistance with this.
I'm using a Macbook Pro (unsure of the year) It's a 13" running an i5 and 4GB of ram. I believe it is running Mountain Lion.
I took the back off and added one strip of 4gb to go along side the strip of 2 and rebooted the system. Now, when the Macbook turns on, it chimes, and the Apple logo appears and it turns off.
I've tried resetting the NVRAM and removing the new chip and just using either the 2 or 2x2 that came with the MBP but to no avail. I've followed the instructions here, but nothing works.
It seems very strange that just adding some extra Ram would cause the system to fall over. I've worked quite a bit on computers over the years and i'm 100% positive i didn't put the ram chip in as such that it would damage the unit.
Do i have any other options here? If possible i don't really want to reinstall the OS and lose my programs. I'm not worried about the data as there isn't much on there but I have Office for Mac 2011(i think) installed and i no longer have the disc. Is there a way to do an OS repair which just overwrites the system files and not data?
As said above, i've tried also booting into the recovery partition but the same thing happens, it starts to load then shuts off..
Very confused!
I hope someone can help
Thanks,
Sam.

I tried to repair the disk permissions but it kept throwing up "live file system repair not supported" errors, plus when i tried to install Mavericks it said my disk was locked.
I did a quick Google and I think I need to boot from a USB stick running Mavericks and try and repair from there..
I'll report back on my findings. Thanks for your help so far.
