Mac air overheating and won't re start ?

Mac book air is overheating and won't re start. Have left it for 2 hours but still warm and still dead. Is the battery going to blow?

I have not heard of this. Are you running extensive applications on it such as video or music editing software? Did you leave it on charge for those two hours, or did you remove the MagSafe adapater?
What I would do would be to remove the MagSafe adapter, let it cool. If you can get it going again, then I would leave things, and see if it happens again. If it does, I would reinstall Lion, and if you continue to have problems after that, I would take it to an Apple store to have a Genius look at it.

IPad Air crashed and won't turn on. tried to hold buttons in but nothing is working

MY iPad Air had crashed after an update. Now it will not restart it make any sounds or show any picture. I have tried numerous methods, but nothing seems to be working. It will not recognize on a PC or iTunes. Please help

Have you tried a reset ? Press and hold both the sleep and home buttons for about 10 seconds, after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot. Happened to me once, about 6 months ago, and a reset got it working again.

My mac cuts out and won't turn on

My macbook stopped working, cant switch it back on. I have plugged it in the green light flashes then stops, still cant switch it on.
help...

Hey,
First thing to try would be to reset the SMC on your machine (http://support.apple.com/kb/ht3964).
Does the sleep indicator on the front of the machine come on at all?

Imac dead and won't turn on after lightning storm

Lightning fried my mac; its dead and won't turn on, in spite of having a surge protector; my question is what part is likely damaged; and what does a repair cost without Apple Care.?
Thanks

Hi rasperryaddiction!
I was wondering if you've tried resetting the SMC (support.apple.com/kb/HT3964). It's very simple to try before considering having the computer repaired. If it really doesn't turn on after resetting the SMC, then contact any Apple Authorized Service Provider or and Apple store near you. Tell them what happened to check if they can give you a quote or something buy, they might ask you to bring it in to confirm the issue. It really does depend on which part was affected.

My MacBook Air shuts down when its more than half way charged and won't turn on unless I plug it in to the adapter? Why is this happening and how can I fix it?

If you really do have a Mid 2013 Mac Air model then it is still in warranty, as the standard Apple warranty is one year from date of purchase. So take it into an Apple store and have it diagnosed and fixed under the warranty. There is some type of hardware problem that only Apple can fix.

I just. Bought an iPad air 2 about two weeks ago. Was working great then it froze on me shut off and won't turn on now?

A reset may help. Tap and hold the Home button and the On/Off buttons for approximately 15-20 seconds, until the Apple logo reappears. When the logo appears, release both buttons.
No content is affected by this procedure.

Macbook air randomly shuts off and won't turn back on

I have a 2011 Macbook Air that was given to me by my sister. She told me about a year ago she spilled water on the keyboard and it stopped working for a while. She took it to apple and they told her it was going to cost 700 dollars to replace so she decided not to. After a while the laptop randomly turned back on and started working fine. I ended up getting it as a free gift and it was working perfectly fine for about a month and a half until recently it randomly shut off on me. After it shuts off, it wouldn't turn back on through pressing the power button I left it alone and after a day it randomly turned back on and worked like normal. After about 15 minutes of use it randomly shuts down and won't turn back on. I tried resetting SMC to no avail. It randomly turns on for about 15 minutes before it feels like it gets slightly hot and shuts off. Any help will be great!

Try running an Apple Hardware Test:

If you find you can't, make an appointment at an Apple store genius bar. The evaluation will be free and then you should know what the problems are with your MBA.
Ciao.

Hi everyone, so I was on my MacBook Pro 10 mins ago and it all of a sudden shut down and won't turn back on? I haven't had it backed up for a while now but does anyone know what could have possibly happened and if it will affect my hard drive?

My MacBook Pro 13inch won't turn on? It randomly shut down itself and won't turn on!!? Will it affect my back up? Hard drive disk? Because it has all my work and personal things I really need on there! Please if anyone can help me!!

Mac mini 2,1 won't turn on

Hi Guys,
i have a really big problem with my mac mini.
It won't turn on.
I don't think it can be the power brick as I can get the mini to start up by holding down the power button whilst plugging it in.
This is the incorrect SMC reset procedure and I get fans runnning top speed and no LED light.
When i startet with this method, everything works.
Ah ups i forgot:
I have all resets done!
NVRAM
SMC (and by reset switch)
New Battery
Bought a new power adapter
etc

Hi,
Witch power adapter you bought ?
I have the same problem i bought a 85w pwer adapter and my Mac mini don't work anymore and i replace it buy a 110w and it works fine .
Probably you are in the same case.

HT3728 Time Capsule turned "off" and won't turn back "on"

My Time Capsule shut down last night--completely turned off--and won't turn back on. It felt warm, so I unplugged it overnight. I tried plugging it back in this morning and it still doesn't have power. I've also tried plugging it in somewhere else, and the hard reset as described on the Apple Support Website. But still no power. The green/amber light doesn't come on at all. Suggestions?

the power supply is cooked in its own internal oven bag..
It sounds like it is beyond warranty but if you have applecare on a Mac that will also cover the TC if it was purchased within 2years of the computer..
Otherwise a self - repair is possible or help from a repairer if you happen to live in an area.. to Apple it is a sealed unit and they will not help you.

IPhone 4S Shut itself off and won't turn on

my iphone 4s has turned off and won't turn on.
it doesn't respond to the power button and won't respond to being plugged in.
the last time I used it was about an hour before I noticed it.
the last thing I did was put one photo on to my photostream.
it had been sitting in an air conditioning room, and on a desk during the whole hour or so I wasn't using it.
anyone have any ideas what might be wrong with it?
i am 100% sure I'll have to take it to a store to figure it out unless it suddenly works.. but any ideas would be helpful....

My 4s did the same thing yesterday. I locked the screen, then about ten minutes later I went to use it and nothing would work. Like the phone was completely dead. I tried everything, plugging it in, reboot, nothing at all worked. Then about five minutes later I hit the lock button again and the apple logo appeared and it started rebooting. Not sure what happened!!

IPad shut off and won't turn back on. Any suggestions ?

I have the first IPad. My iPad shut off at 72 percent battery life and won't turn back on.
Any suggestions on what I can do ? Is it fixable ? Do I need a new Battery ?

Not charging.
1. Reset iPad; hold the Sleep/Wake and Home button down until you see the Apple Logo
2. Try another wall socket
3. Try another cable (make sure it's an original Apple cable)
4. Try another charger (make sure it's an original Apple charger)
5. Clean Lightning port with compress air or new paint brush

IMac G4 just turned off and won't turn back on

When I woke my iMac G4 from sleep, it turned on then all of a sudden turned off and shut down on me and won't turn back on. Any suggustions? It has Mac OS X 10.4.11 and before today worked perfectly.

Replies to such old threads are likely to be a bit curious.
Mostly as to a reason why they are brought up, now.
The link to XLR8 page shows an earlier iMac G4 model
and that is slightly different than the last iMac G4 USB2.0
(15"/17'/20") models. They tend to be more like this inside:
•Mr Totes iMac G4 USB2.0 take apart:
http://www.mrtotes.co.uk/page1/page1.html
Thermal paste and other steps are required with access
into these layers where the 3.6V 1/2AA lithium battery,
and factory RAM slot, HDD, optical drive, etc, are located.
•3.6V Lithium 1/2AA PRAM clock battery, example:
http://eshop.macsales.com/item/NewerTech/BAA36VPRAM/
Also, the 17"/20" can use 2048MB RAM when both slots
get upgraded to 1024MB each, respective to type in each.
The bottom slot uses the same SODIMM as the last iBook
G4 (mid-2005) does, as an upgrade, exact in specification.
The power supply can be tested via small ports in the bottom
under metal plate (by reset button, by airport card slot) to
see if the power supply has failed in one of its voltages.
Anyway, curious to see an old thread come up like this.
In any event...
Good luck & happy computing!

Power Mac G4 (APG Graphics) won't turn on

Hi,
My Power Mac G4 (APG Graphics) won't turn on at all. This is not the first time, it also happened a little over a year ago and after about 9 months I plugged it in and it worked fine for almost six months. Each time there had been what could be considered "trauma," the first time we had moved about 400 miles and although it rode in the car with me, there was a lot stuffed in with us so it wasn't as gentle a ride as I'd hoped. This time we had an ice storm and I was actually using it when some power surges took place. It was plugged into a surge protector and everything else that was plugged in works fine.
When I press the power button, nothing happens. No chime, no light, nothing. I've pressed the PMU button and replaced the battery. I've switched to a different power cable. I've removed each of the RAM sticks and tried starting it while each was removed and after reinstallation. I've disconnected all peripherals. I'm stumped!
Any suggestions would be greatly appreciated!

I followed the procedure I found through other discussions, but when I went to the link that was suggested in the previous post I found that I did one thing wrong. When resetting the PMU didn't work the first time, I continued to press it after each subsequent attempt. So after changing the battery, I pressed the PMU. After checking the RAM, I pressed the PMU, etc. According to the directions in the link, pressing the PMU more than once could wreck it completely. Does anyone know how to tell if I've done that or if I can do something else now? Thanks.
