8120 turning off randomly during call

Got new 8120 from Orange UK - works great apart from randomly turning itself off - have read posts with similar problem but on my phone the problem only occurs during calls with annoying frequency ! Tried wiping phone and re-installing OS but didn't work. Any advice greatly appreciated.

If you've wiped/reinstalled OS there may not be much left that can cause it - are you running the latest version of firmware on the device?
Might be worthwhile to call Orange tech support and see if they have encountered any known issues and have any fixes or if it could be a device or possibly even a network issue (but I doubt it would be that).

IPhone not automatically turning off screen during calls...

ok, getting sick of this b.s. and i have tried the settings and whatever else i can find... NOTHING WORKS!
WHY!!! why when i make calls does it not turn the screen off so that i don't unintentionally mute people or accidentally put them on speaker??! w-t-f apple???
also, sometimes when it actually does fade out, it stays feded out... and i have to hit buttons or the screen to wake it back up?!??! w-t-h apple?!?!
anyone else having this problem? i tried to search the forum and can't find anything on it...
thanks

The iPhone 4's proximity sensor is just above the earpiece speaker as shown here:
If your Otterbox is covering the sensor, it won't work. Otterbox makes cases for the iPhone 3/3GS and iPhone 4. The sensors are located in different places, so a case for the 3/3GS won't work for a 4.
Take your case off and see if you still have the problem. You may have a bad sensor and need to make an appointment to have an Apple Retail Store Genius look at your phone. http://www.apple.com/retail/geniusbar/

My iPhone 3gs turns off randomly (applecare sent it back as it was!)

Hi, had my iPhone 3Gs 32GB Black since about August 2009. From the outset it has turned off randomly ever few days or so, usually when I am in the middle of a call. I tried resetting the phone. Removing all the apps. etc. etc. but no luck.I stuck with it thinking that the problem would go away or that some future software update would fix the issue but also no luck.
So I took it into Movistar (the dealer for the phone here in Spain) a couple of weeks ago and they duly sent it off to Applecare for repair. Apparently you cannot do that yourself, it has to go through the store.
Anyway, got the phone back today with a really shoddy looking photocopy from AppleCare Service in Cork (Ireleand) saying that " their technicians could not find any problem with the phone..." blah blah blah. and that the problem should fixed by reset!
So what do I do now. I know that if they have not actually found the fault then the issue will persists. The Movistar sales woman said to just bring it back in that case and they would send it off to Apple again (for another two weeks...).
Is there any way I can contact Apple CAre direct about this? Anyone got any suggestions?
Cheers,
Tony

Thanks, but no Apple stores in Spain. Have to go through telco. Movistar. Will just send it back again for repair... see if they can fix it this time or give me a replacement.

MBP turning off randomly while on battery

So my MBP keeps turning off randomly while I'm using battery, first few times it happened I thought it had just got to hot and turned off because of that. But after it happend a few times i noticed that its not even hot to the touch. Its happening what ever i am doing even when I have very low cpu usage like listening to i tunes, or just watching a movie.
Any ideas what it could be?
Thanks for any help you guys can give.

I have the same problem. It is most likely the battery has become faulty or possibly damaged. Best to replace the battery or if you can call one of the genius' at the mac store.

Iphone turns off randomly when its locked

My iphone turns off randomly when its locked, also the screen flashes occasionally when im making a call. And also in the usage section it doesnt come up with any information in the time since last full charge section, even though ive left it on charge for a solid 8 hours over night the last two nights, any ideas????

Hey bbkae
Continue you troubleshooting with the article below to check the health of your battery. I would try to run hardware diagnostics on it to see if it passes the test.

3GS turns off randomly

My iphone has been turning off randomly while using apps and making calls for a while now. I have tried restoring it but does not fix the issue. The phone is 3 years old. I would get a 4GS but since the 5 is coming out later this year Id rather wait for that. But I really need a working phone right now.

You could try to disconnect and after a few minutes reconnect the battery. That theoretically resets the phone BIOS and is supposed to help regarding the reboot issue (see post by NIKKOH007) http://discussions.apple.com/thread.jspa?threadID=2471090&start=2055&tstart=30
Or replace the battery altogether with a newer, iOS 4 compatible battery. At iFixit.com they have come to the conclusion that not all batteries in the 3GS are necessarily iOS4.x compatible or a battery defect may be exposed after updating.

Ok, firstly I know this topic has been coming up on the forum, but I haven't found any of the threads helpful or offering a clear solution so far.
I had my iPhone for 5 months and during that period I haven't installed any apps on it. Everything worked fine, no problems at all. Just recently I installed apps for the first time and it was fine for a while (2 weeks or so) but then it started turning off randomly. I can only hold in the sleep button until the apple logo comes up and it turns on again.
I figured it had something to to with the apps so I did a reset and only kept apps that 'seemed' to me safe to have (Facebook, Wordpress and Skype). But the problem still remains.
So here is my question, has anybody found a soild solution to this? Should I consider returning it? Can it be a hardware issue?
Thanks in advance for any help

You're welcome.
Does that mean that every time I add applications and this 'turning off' happens, I can't have any apps on my iPhone? (sadly that would defeat the purppose of haveing an iPhone to a large degree)
No. If this happens every time you add applications, there is something wrong with your iPhone. I suggested removing all 3rd party applications to see if the same occurs without any 3rd party applications installed. I ended my previous post with the following:
*I don't believe this will make any difference. _If an iPhone reset, a restoring the iPhone with iTunes from your iPhone's backup, and restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup does not resolve it, then your iPhone has a hardware issue._*

When did you get this firmware version? My TBD is at 22.2 and the TBD bus is at 23.4. I thought I had the latest firmware.

Has anyone else experience their iPhone 5 turning off at a high percentage and turns off randomly turning back on with the red battery needing it to be plugged in?

Have had my iPhone 5 for almost a year now, love it, but lately it has been turning off randomly with percentage rates of 50% or above and when I go back to turn it back on it has the dead battery sign on the screen. I am trying to figure out if its hardware issuse or if its the battery itself. Just need suggestions on what to do? Took it in and they want me to restore it but I want to try something else before I wipe it clean.

1) Try This...
Close All Open Apps... Sign Out of your Account... Perform a Reset... Try again...
Reset ( No Data will be Lost )
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
Release the Buttons...
2) Also consider Deleting any Apps you have Purchased / Downloaded but you now never use...
3) Make sure you have the Latest Version of iTunes (v11) Installed on your computer
iTunes free download from www.itunes.com/download
Then...
Connect to iTunes on the computer you usually Sync with and Restore

Macbook air (11", mid 2011) turns off randomly

My macbook air 11" (mid 2011) turns off randomly. Sometimes, in the middle of something a black screen. After a few seconds it starts up again, on using a key. It restarts in the application I worked on before. Strange!

Do you have put hard drive to sleep when possible checked? Try unchecking it.Have you tried repairing permissions in utilities? You could also do a pram reset. Command/Option/P/R keys at startup for three chimes.

While doing the most recent firmware upgrade, my iMac hung on the spinning ball. The instructions said "not" to turn off power during the process, so I don't know what to do. The ball is still spinning.

If you tried resetting the ipod and it still keeps having the same issue you described, try setting the ipod to disk mode.
Here is an article from the apple support website on setting the ipod to disk mode.
http://docs.info.apple.com/article.html?artnum=93651
If you can get the ipod into disk mode, connect it to the computer and rrestore the ipod using itunes.
if the ipod will not go into disk mode, you can return the ipod or set the ipod up for service via the apple ipod service depot.

MacBook Pro Turns off Randomly Only when logged in OSX 10.8.2

Hi,
I have a 2010 Macbook pro with Mountain Lion 10.8.2. For a couple of weeks now, when its not plugged in to AC it turns off randomly, not at any specific battery%.
Things I have tried already that were not helpful:
- System profiler battery: 374 cycles, Battery Status: Normal
- SMC reset
- Clean install of Mountain Lion without any Migraion of old System files (wanted to do this anyways before the problem arose)
- Its does not seem to be a heating issue, has happened at low temperatures
What I have noticed is that if I either run the diagnostics at startup or enter to recovery mode, I can run the battery all the way to 0% (lasts a while) and this random swtiching off doesn't occur. It only happens when I am logged in to OSX. This makes me think its not a battery issue either.
Any help would be great.
Thanks!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Why does my Satellite C655D-S5300 turn off randomly after about 45 minutes to 1.5 hours

Was wondering why my laptop turns off randomly for no reason. It does this even if no battery is connected and the AC adapter is connected. It starts right up again if I press the power button but only lasts for an hour or so then shuts down again? When it starts I do hear the fan going and the system works just fine until it randomly shuts down. Upon restarting the usual windows error indicated improper shut down happened. Could it be a bios problem or a virus?
Solved!
Go to Solution.

Hi Peter,
Well, I finally gave up and took it into a professional repair place who simply updated the BIOS and that solved the problem. Runs like a champ now. I should have checked that before taking it in...would have been a quick fix and saved
$100. Oh well, thanks for the reply.
