My nokia c300 turns off as if i took my battery of...

when i use a data cable that i bought , and that it works perfectly in order to charge data into my mobile and i took it out of the mobile, the device automatically turns off and therefore i need to change some of my settings again. its really annoying.

This is a suspicious sign of power supply failure. I would have that checked into. Others who have had similar problems have had the power supplies replaced which fixed the issue.

My nokia 6230 turns off without cause!?

my nokia keeps turning off,
i am reasonably sure it is not the battery as this problem occours while charging aswell as without charging. Also occasisonally, it doesn't turn off completely, just goes onto a white screen and can only be stopped my the removal of the battery.
Has anyone else had encountered a similar problem and can help me?
Thankyou

This is usually a software error that can be fixed by reinstalling the OS. You can't do this you_rself as this model is too old to be supported by the software updater, so you have to take it to a service point.
Definitely agree with this. Sometimes a slightly corrupt firmware might compromise the performance of the phone as a whole. But there is also a possibility that it's a hardware problem.
Good luck

Nokia 5530 Turns off when making a call

I have a real problem, my Nokia 5530 turns off if I try to make a call or receive one, the only way it will work is if the headset is pluggeed in, I have tried everything, Restoring Factory settings, Hard reset etc...
Anyone else have this problem? Help...
Cheers
Rob

I have exactly the same problem. I Went to a Nokia Care Point in Lisbon and they upgraded the firmware to the New one ( 11.0.054 ), but with no success.
I tried old SIM Cards, Newest SIM Cards, With / Without Memory Card, Factory Settings, nothing Worked. I Guess it´s probably hardware, maybe a faulty battery.
I ´ll have to send it to repairment..it´s really upsetting.

If you are in Hong Kong, go to Digital Trade, 1/F, Sincere Plaza, Argyle Street, and it will cost you 120-150HKD, but before you go check that your power button and home button are working correctly, if not press as hard as you can, hope this will help.

I just got my battery and iphone 4 screen fixed and when it turned off because there weren't any battery left, I tried charging it. Now it won't turn on or charge... what do i do?

I just got my battery and iphone 4 screen fixed and when it turned off because there weren't any battery left, I tried charging it. After charging it for like thirty minutes, I pressed the home & lock button and it turned on for a moment for me to see that it was only at 1%... So basically it wasn't charging for that entire half hour. Then, I tried connecting it to my computer and nothing is popping up... so it won't turn on or charge... what do i do?

Who repaired the phone? I suggest taking it back to this repair facility. Since Apple replaces phones instead of repair, the repair facility would be the one to take care of your problem.

Turned off iphone 5 to preserve its battery and now it won't turn back on

Hello!
I've got my iPhone 5 16gb around 1 year now and today, i needed to preserve its battery life (97% remaining )so i turned it off. A few minutes in i needed to make a phone call but it won't turn back on. I've tried the recommended tips such as:
holding both home and lock screen button
DFU mode
Charging it
Nothing seems to work, i do not know whether the lock screen is broken or not or just whether its a battery or ios problem. Funny thing is that a few days before this incident, there was an 7.1.2 update so yeah idk. Please help. It will be a pain to buy another iPhone

Hey there iDopey,
It sounds like you are currently unable to turn on your iPhone on or it is on, but the screen is black. First determine if the unit is on but has a black screen with this:
Display has no backlight or dark screen
Toggle the ringer switch to see if the unit vibrates. If it does, it could be that iPhone is getting power, but is not displaying any image.
Try turning iPhone off and then on again.
While connected to the iPhone charger, try to reset the iPhone.
If the low-battery screen appears, charge the iPhone.
If this is the case follow the last step in this post. If not, then move on to this section:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
If that still does not resolve the issue:
Issue not resolved
My issue is still not resolved. What do I do next?

Nokia 7373 turning off help

I'm having a bit of trouble with my Nokia 7373, it won't seem to switch off. When pressing the switch off button it makes the vibrating sound and has the screen to whether i want the phone turned off or not.
I'm trying to get my battery to go dead but am worried that it may not turn back on again.
Hopefully you get what i'm trying to say.
Thank you

Hi fedup
Have you tried backing up your data and reformatting your micro SD memory card?
Is there a software update available on NSU, which would give you a fresh start?

Nokia X6 - Turning Off GPS

Hi folks,
Is there a way of turning off the GPS so it is not constantly on and it will either prompt me to turn on when using OVI Maps or i can turn it on myself when I need to?
Thanks

I second what jjegan said, if an application's not actually using the GPS it'll be switched off, and it'll only turn itself on when an application asks for position info. This isn't Android.

Nokia Asha - Turning off the SMS delivery messages

I'm using a 301, but guessing the options are pretty standard across the Asha range.
Is there were an option for turning off the message displayed to confirm the delivery of an SMS (the one that pops up and takes up the whole screen for a couple of seconds).
Thanks in advance!
PS - Also the message displayed when it's sending. Personal preference of course, but I'm just happy with the icon in the top of the screen.

I don't know the menu layout of the 301, but my C3 has the option to keep the delivery reports embedded which does not show a note, but the delivery status can be checked by looking into the Message Details.
However, my 311 only has the option to either turn off the delivery reports or else get that full screen note. I don't text much so certainly not a thing to disturb me. If your phone does not have the option to keep the delivery reports embedded (Messages> Settings> General or Text Messages> Delivery), you need to turn of the delivery reports. No other way than that.

TS2771 My ipod touch 4th generation just turned off on me, it had full battery and now wont turn back on, how do i fix it?

I tryed plugging it in to charge and pressing down on the hold button and home button but its not doing anything, How do i fix it? Not sure what my operating system is but i know i havent updated to the newest version.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iPod fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

My ipod turns off for no reason and the battery is fully charged

I've had my ipod for a week and have had nothing but problems with it! It turns off for no reason while listening to music and the battery is fully charged. It even does it in the car while connected to the fm transmitter/charger. Please help! Also I bought a movie from itunes and I can hear the movie playing but I can't see it play. Thanks for your help!

I've had my ipod Photo for almost a year and just had the same thing happen for the first time - it just stopped, fully charged, while playing. And, it froze up in the sleep mode. I followed the instructions to reset it ( toggling the Hold Switch on and off) but nothing happened on the first 3 tries. I let it sit for about 15 minutes while searching in the Help & Apple Discussions forum and, just now tried toggling the Hold Switch again and noticed before doing so, that it had shut off. I toggled the Hold Switch to the locked position (Hold) then to the unlocked position and it came back on!
I'm sorry I can't tell you why it happens. If anyone knows, I'd like to know, too.

My ipod classic won't turn off and it's draining my battery

I bought my ipod in September 2007 and it worked fine until about 2 weeks ago just after the last software upgrade (not sure if it is connected) but now I can't turn it off.
I have also tried the sleep function but all that does is make it inactive whilst leaving the details on the screen and still draining my battery.
Since the batteries have a finite life is this Apples new way of getting our hard earned cash now that the battery life has improved!
Can anyone help me solve this problem I have tried reset (several times) and restore and neither solved the problem.
Thanks

There are at least two diff probs here. 1) Ipod is hung and won't respond to turn off signal (pressing bottom of wheel) at all. This happens soemtimes when, for example, your ipod is connected to a docking device and you turn it off while pressing bottom of wheel wheel - then you immediately unplug it the ipod, which lights it up again -- sometimes it will won't then respnod to a a shut off signal by presing bottom of wheel. This prob has been recurring on ipods for years and can be fixed with a reset.
2) When you press the bottom of the wheel, the ipod turns off for about a half second or so and lights right back up again. This prob i smore pernicious, has an unknown cause and is not fixed by a reset. If you restore, the prob can be fixed but only UNTIL you reload you music files onto the Ipod - then the prob automatically returns. Some suspecdt this prob has to do with a file problem and ipod's inability to appropriately deal with the file problem.
