Mini Mac Switches Off.

*Wits End,*
My mac mini 2009 model has recently started switching off I have tried the SMU reset with no success, the unit is stubborn to switch back on and I have to hold the on button in for sometime, it may then stay on for 5 mins or 2 hrs but switches off again I have removed the outer case and dusted the unit but I don't think its a overheat/fan problem.
It seems since I used an external hard drive the problem began, has anybody experienced a similar problem could it be software problems.

I'm sure something is overheating. Could be an accumulation of dust, or a malfunctioning part. I would make an appointment with an apple genius bar at your local apple store.

Mac Switches Off (Is this a battery problem)

My Mac switches off automatically, even if my battary has 68% power left. I can only use my Mac if I have the Power Adapter plugged in.
If I turn my Mac on without the Power Adapter it shuts down before the Apple logo appears. Could this be a battery problem.

Same (identical problem) problem here. A few days ago it was not so evident, I felt like I was taking crazy pills: putting the book to stop and, when back, off.
Anyway now the mbp refuses to be turned on if the power cord is not plugged. Bad.
I'm gonna call for a replace tomorrow. (Little note, this is my third macbook pro. The first had broken isight and the second was a pit of panics.... speechless)

Mac Pro will not boot, power light flashes once and then Mac switches off

One of our Mac Pro's will not boot. When pressing the power button the light will come on briefly and the Mac will just turn off again.
I have unplugged the power cable and held down the power button for 10 seconds but this did not help.
Any suggestions for me before I call up Apple?

Most indications from flashing power lights are telling you that there is not enough working memory to start up.

Will Apple TV stream iTunes media saved on Time Capsule with mac switched off

I have Apple TV gen1 running on 40gb internal HD. I was wondering if upgrading to gen 2 and using Time Capsule, will macbook need to be on/on network, or can Apple TV gen2 stream direct from iTunes Media saved on Time Capsule

Welcome to the Apple Community.
Both models of Apple TV require iTunes to be running on a computer in order to stream content from it's library.

Why has my ipad mini screen switched off and i cant get it on. It still connects to the computer but wont switch on. ive tried a restoring it. it hasnt helped

I was watching a video on the internet when my ipad screen suddenly went black. its not responding but still connects to the computer fine. I tried to restore it and it hasnt helped. it says its restored but the screen still wont function. Is it broke for good?

Is it possible that your battery has died? or that it's gotten too hot?
It is possible that the screen has died, or it could just be a glitch (my screen stopped responding once, eventually all I needed to do was give it a reset)
Since your device responds it means its guts are still good.
Is it still under warranty? If so and if the screen has failed it could qualify for a replacement.

My ipad has been switched off since 2 week of no charging..now wen i kept charging it first displayed charging symbol then it became blank.after a whole day charging also its showing blank i holded home n sleep buttons even but not even logo appears.

Ipad mini has switched off and became blank.How to restart it?pls help me out

The type of battery that's in your iPad is quite resilient. However, letting that battery run down completely, and leaving it that way for a few weeks is a quick way of destroying it's useful service life. I suspect that you may need to have it replaced.

Phone switch off n restart abruptly

Hi,
My phone has couple of problems
1. When I put for charging by turning it on, after a while say 15 min it stops charging n hangs but led indicator would be glowing, I have to restart the phone by holding power n volume up button.
2. If I keep phone idle for more than 30 min, it switches off automatically.
3. Some times it restart automatically
During all these above scenarios phone back would be heated so much. I think bcoz of this heating issue, it's switches off.
I have tired repairing it through Pc companion but of no use.
Please let me know what to do. It's just 2 weeks old phone. Can I go for replacement?
Regards,
Balakrishna

It hadn't crashed but I decided to run a software repair through PCC utility for good measure.When I set it up again I updated everything (including "Video") except the "What's New" app.And I disabled automatic updates in every place where apps update themselves. It went from crashing 2 or 3 times per hour to crashing just once in 4 hours, after I uninstalled the update for "What's New".The last time it crashed was before the "Xperia Lounge" app updated earlier, about 6 hours ago. Then I did the software repair in PCC.My guess is it could have been either or both of those apps causing the crashes. If it crashes again I'll be stumped as to what it could be. Like I said, it hasn't crashed since 6 hours ago. I'll report back if it crashes again.If I don't post in this thread again it means my problem has been solved.

HT4623 My iPhone 5 is switch off yesterday it is not on yet what I want to do

Hello my name is raja . My iPhone 5 is switch off on yesterday . I down Load some games from AppStore . That after I listen some music .after 10 min it switch off suddenly .i try to switch on but it not on . I connect iTunes &reseting software .nearly 2 hrs it show waiting for iPhone .what I want to do .

Hi rajaabbas412!
I believe I have found some articles that will help you troubleshoot the issues you are seeing with your iPhone. First, in order to get your iPhone turned back on, you will want to try the steps listed in this article:
iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
http://support.apple.com/kb/HT1430
Specifically, you will want to try this:
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
You will also probably want to hold the Sleep/Wake button and Home button for around 20 seconds just to be certain. If that doesn't affect the iPhone, you will want to refer to the steps in this article:
iOS: Unable to update or restore
http://support.apple.com/kb/HT1808
The first two steps in that article will not be relevant to your situation if you phone is no longer turning on, so you will want to skip ahead to step 3. Thanks for using the Apple Support Communities!
Cheers,
Braden

USB WD Drive wont switch off when Mac Mini sleeps

Can anyone help. My WD USB drive remains powered when my mac mini sleeps. I have tried "switch off hard drives when possible" in the preferences but still no joy. Any advice?

Hi Phras81-
Greetings and welcome to the Apple boards
Unfortunately the inability to sleep is a function of the drive itself. Which model WD drive? If it is a MyBook and you can return it I would suggest that you do so and get something else.
Luck-

Mini suddenly cuts / switches off

Hi,
I own a Mac Mini (1,42GHz, 1Gig ram) and recently it's done some strange things. While working it suddenly switched off. It was like somebody just cut the power. I pushed the button to turn it on again and the led would only appear for about 1s before the mini cut off again. When waiting for about an hour leaving it switched off it worked again, but only for a few minutes. My first guess was a problem with the overal power (bad contact or something) so I tried the mini in another plug and in another house, but the problems continued. I couldn't run the hardware test since it kept cutting off before it could complete any test.
Then I decided to visit the local Apple store (not a 'real' one as it's a shame they don't exist in Brussels, but a certified reseller). I wanted to ask them if they could try it with a different power supply as that might be the issue. However, since I bought the mini from the online Apple store and not their store they weren't allowed to test it unless I brought it in officially, paid them, would pay them more if they couldn't find anything and they would send it to Apple for repair.
So I decided to call Apple first and they had never heard of the problem. I reset the PMU (?), tried some stuff, but nothing worked. They told me to go through the local store to get it sent to them if the problem persisted. So the next day I wanted to reproduce the problem before going to the store to show them right away and the mini worked for about 5 hours straight. It seems the longer I left it switched off, the longer it work afterwards. When waking up from a sleep it crashed again. Then I thought it wouldn't turn on again like it did all the time the day before. However it ran perfectly for 2 whole days. Since the mini is pretty essential for my studies I gave it another try and decided not to bring it in. I was able to run the hardware test which told me everything's ok.
Right now it works pretty well, but it still suddenly cuts off every once in a while (about once a week). Did anyone ever have this problem before or has a hint on how to prevent this from happening? Would it be better to bring it in for repair anyway? My fear is that they'll leave it on for a week, see that it works perfectly and send it back saying there's nothing wrong with it. In case nobody knows what to do I did think it would be a good idea to post the problem here anyway to make it known.
Greetings and sorry for the long story .
Edward.

Only valid entry in Apple's Error Codes List for -127:
-127 = fsDSIntErr /*non-hardware Internal file system error*/
You have probably seen the -93 (or was it 96) and -122 PMU codes, but 127 is a first for anyone it seems, even Google won't find a -127.
The -93/96 remedies were mostly centred around PMU resets.
The -122's were a little bit more involved. A Googled report lists the local Apple Store saying it would need a logic board replacement. The user was a bit miffed when 5 days later his machine is ready to be picked up and only the battery was replaced. It PMU forced shutdown -122 again after arriving home. He bought a conditioning UPS and plugged his Mac into that and so ended the report. No further information available on if it solved the problem or not.
Add to that users shutting down and running DiskWarrior/TechToolPro checks of the hard drives as all the -12x error codes are file system related. However when I grep'd the headers list of CarbonCore for -93 it is a network bridging error, and -96 is a Serial port not powered error, so I have doubts that the PMU is using the standard Mac error codes list.
Apple's own online support database is mysteriously silent on any PMU forced shutdown entries.

If someone knows please help!!!!!
I tried different cables and different computers and nothing. I can't restore because it's no recognized...
Thanks a lot!!

Hi, my iphone 4 was working fine a couple of days ago, but suddenly i plugged the device to my laptop and after a while i realized it wasnt charging, i have tested on a lot of computers but i got the same issue, even on a mac but its not detected.

As you can see there is no charging logo when the phone is connected

My Mac Pro does not switch off.

It worked before Lion. Installed 10.7 and also upgraded to 10.7.1 but, on both cases, it does not switch-off. To be precise it "sometimes" switch-off but many times it does not. Let's say once on 15 times... With Leopard I nevere had this problem. (it persists also after a PRAM reset). I also run a second problem but only once and only upgrading to 10.7.1 (not to 10.7). It says that my RAM was on wrong position.. I had to remove and install the RAM again and it worked.
Any other case like this? (This append only on my MacPro - early 2009. On my MacBook and my MacBook Pro OSX Lion works fine).

Is there a pattern to the chimes, or are they simply random, as if the Mac is repeatedly rebooting on its own?
Have you tried a "Safe Boot"? Press and hold a Shift key as you power up the Mac. Does it start then?
If it starts at all "Safe Boot" will take much longer than usual, that's normal. Shutting down will take longer also. Try it.
