Suddenly Turns Off - Why?
My Mac Mini is just over a year old. Starting today, it will suddenly turn off for no apparent reason. If I restart it, it will shut down even faster then the previous time. The bottom of the computer is hot to the touch, but I can't say if it it hotter than usual or not.
It's positioned in the same spot I've always had it.
Does this seem like a faulty power supply or an overheating issue? Something else?
Thanks in advance,
Lauren
If you have an Apple store in reasonable reach, then that is certainly a good place to get diagnostic help and initiate repair, but with a problem of this sort it may be rather too easy in that environment to misdiagnose because by the nature of taking the system there, it will have cooled significantly by the time the Genius gets to play with it.
It may be a relatively simple problem of dust/debris build up, which could be cleared up by using a good vacuum cleaner on the vents around the edge of the base and on the rear panel. Alternatively, if you have already had the top off this unit in the past, it might be a good time to do so again and carefully vacuum the interior, or blow it out gently with a can of compressed air to dislodge and remove any debris inside. If you have not previously opened the system but feel confident in doing so, this would not void the warranty in itself if there were any cover remaining, but if the system is over 1 year old and you have not bought AppleCare, the warranty is expired in any case.
Chances are that the problem is caused either by dust/debris clogging the air flow, or by a loose heatsink.

Frozen or unresponsive iPhone
Try this First... You will Not Lose Any Data...
Turn the Phone Off... ( if it isn’t already )
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear and then Disappear...
Usually takes about 15 - 20 Seconds... (But can take Longer...)
Release the Buttons...
Turn the Phone On...

Cable suddenly turns off and is "updating" often
In the past week when i turn on the tv it says updating, probably 3 times this week. Then, in the past day while i'm watching tv it suddenly turns off and restarts, updating again- four times in less than a day. Why is it doing this?
Try "Core Temp" Aida has not be updated in years. Its most likely overtemp of the CPU. A power problem is the next most likely.

My iphone 4 suddenly turned off and now its asking me to restore my phone
My iPhone 4 suddenly turned off without any notice and was dead. I would hold the sleep and main button together and nothing would happen. Once home, I connected it straight to the Adapter and now it is asking me to plug in itunes and 'Restore' my phone. What could have happened? Why is it doing this? never happened before and dont now why it occured. Please help!
Well if its the first time its probably nothing to worry about, things happen. If it happens again i would recommend uninstalling the last app you installed, if that fails take it to the apple store because it could be a hardware issue.

MacBook suddenly turns off at 40% of battery charge and trackpad doesn't work
Hello,
I had to replace the battery of my white MacBook (13 inches, mid 2010), because it was swollen, and the capacity was about just 20-30% of its original one. I bought a new one. Specifically, this one. After replacing it, I have those problems:
When I run on battery, the computer suddenly turns off at about 40% of the charge. No warnings. Just turns off.
The trackpad is not working properly. I can move the mouse, but I can not click. The swollen battery was pusing the trackpad, and I guess it's broken now. I don't know if I can replace it.
Coconut battery tells that the maximum charge of the battery is below the design capacity. Not sure if this is a problem, or Coconut battery is just comparing my battery's numbers with the theoretical numbers of a brand new battery. Check a screenshot
The battery drains too fast. From 100% to 65% in about 20 mins. So, at the end, I have less than 1 hour of battery time.
I've tried resetting the SMC, following these instructions. Specifically, pressing (left side)Shift-Control-Option keys and the power button at the same time, releasing all the keys and then pressing power button to turn on the computer. Not worked. I think it was even worse.
Could it be a problem of this specific battery? Or maybe just the MacBook doesn't accept batteries like that one? It's not original.
In the first case, I would return the battery to get my money back. In the second case, I guess I should have bought an original one.
Additional data that may be useful:
Mac OS X 10.8.5 (12F4S)
EFI boot ROM version: MB71.0039.B0E
SMC version: 1.60f6
About EFI boot and SMC versions, those are the last available official updates, obtained from here.
Many thanks in advance.I'd say it was a faulty battery.

My iphone 3gs all of sudden turned off and does not want to turn back on.
Charge it with a wall charger for 15 minutes, then hold the HOME and SLEEP buttons until an Apple logo appears, about 10 seconds.

IMac 2008 emc 2211 suddenly turns off and back on, RAM problem?
I have an iMac from 2008 emc 2211.
Two years ago i upgraded my RAM from 2GB to 4GB Crucial memories.
Two weeks ago my imac started to suddenly turn off and back on inmediatly. Recently it stared to happen more often to the point that it can't boot completely and show the desktop
I checked the power source and it was fine.
I opened the computer and pulled out the power supply and it seamed to be fine.
I tried to run the hardware test with the disk that came with the computer and it can't even finish the test because it turns off.
Before it couldn't boot anymore i checked if it was overheathing with smcFanControl and the temperature was always around 44C, so it was fine.
Could this be the crucial RAM that is failing?
thanks in advance.Ok, i've replaced the RAM and the power supply and the problem persist, so it seams to be the logic board that is failing.
Any ideas? -

I was playing songs on Itunes while charging my iphone 3 then suddenly turned off. I pressed sleep and wake botton for 10 mins but no logo appeared.What happened?
Sorry, but if you see the "connect to iTunes" screen on your phone, the only option is to restore, backing up the phone is not possible at this point, even importing the photos might not work anymore.
