Hi Piet0755,
I apologize, I'm a bit unclear on what you mean by reinstalling iOS. If you have restored your iPhone to factory settings and tested without restoring any of your backed up data and the issue still persists, you may need to have your phone serviced. You may find the following page helpful:

I'm sure your'e going to tell me I just need a new phone but maybe there is hope for my iphone 4. It will not charge past 66% (it's not the charger), it turns off when unplugged, and it will not even let me turn my wi fi to the on possition. Help!

Hi there 8472kck!
I have some information for you that can help you troubleshoot this issue a little further. That information can be found right here:
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 15 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.

My display goes off when Battery being charged on Acer E5-511 after upgrading to Windows 10

I upgraded my window 8.1 to Window 10 on Acer E5-511 machine yesterday. I notice that when I switch on power to charge its battery, a beep sounds and display goes off. when power is again switched off the display comes back with a beep again. However, when the machine battery is allowed to charge for some time, either it goes to hibernation mode or stops working since display does not come back even after switching off the power supply. This peculiar problem did not existed when I had used this Notebook with windows 8.1 for past eight months. Can any one help me to solve this problem as i am being forced to charge the battery only when Notebook is not powered on.

Hi, RomeroSalsa.
Thank you for visiting Apple Support Communities.
I understand that you are experiencing an issue with the responsiveness of your iPad mini while charging. I would need a little more information on how you are charging the device to provide a better answer. While the steps below are not exactly labeled for this issue, they may help resolve the issue.
If the battery doesn’t charge
If the battery doesn’t charge, unplug your device and try these steps:
Look at the connector at the bottom of your device and make sure it’s free of debris.
If you're using a USB power adapter, make sure it's plugged in all the way and the power outlet is working. If you're connecting to a computer, make sure it's on and can charge your device. To charge an iPad, you might need to use a USB power adapter and plug into a power outlet.
Try a different USB cable, USB power adapter, or USB port.
If everything seems to be working, reconnect your device and wait for 30 minutes.
If your device still doesn’t charge, try to restart it while it's connected to power. If you can't restart, reset your device.
If you can’t charge your iPhone, iPad, or iPod touch

Is there any way to keep the flash from going off when you receive a text or other notification?

I have an iphone 4s. Is there any way to keep the flash from going off when you receive a text or other notification? I keep it next to my bed at night and keep thinking there is lightning when something comes thru. LOL

Go to Settings>General>Accessibility and turn LED Flas for Alerts to Off.

When FT is full screen, camera goes off when swiping to a different app

When FT is full screen, camera goes off when swipping to a different app or the desktop. This is frustrating to the other person. We were having a discussion and I said I wouls look it up and when I swipped to Safari, the camera went off. It makes the other person think the connection has been lost. Anywhere to report issues like this to Apple?

In reading other threads, I found a few that recommend a hard reset to solve the issue. I have tried it, and thus far haven't expereienced the problem again. Hopefully that's it then

My iphone 3g running ios 4.2.1 goes off when it is idle

i need help,
My iphone 3g running ios 4.2.1 goes off when it is idle and i have to reboot it before it starts work.
it does not go off when it plays music..... or plugged into the PC.

It's likely running slow because of iOS4, not because of apps being open. Standard troubleshooting...
Try a reset by pressing the home and sleep buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
If still a problem restore from your backup.
If still a problem restore as new, i.e. without your backup. See how it runs with nothing synced to it.
You'll most likely need to restore as new to get it running as good as it can. A 3G will never run as good on iOS4 as it did on iOS3.

Macbook works fine when plugged in, turns off when unplugged.

Hello all,
As stated my 2008 Unibody 13 inch, serial number W8******1AX turns on and works fine when it is connected to power.
When it is unplugged it instantly turns off and turns its fans on full until it depletes the battery (so it is obviously getting power.. just not where I want it)
Since the problem began I have tried two new batteries, neither of which had any different symptoms.
Before this, the computer had an intermittent life, it would turn off when it saw fit, which got progressively worse.
I have followed the guides to resetting the SMC but have had no luck
I have been running it without the battery (to save it charging and discharging for no reason) and sometimes when plugged in without a battery
the magsafe green indicator light goes from dim to bright.
With the battery installed it stays bright orange until it is charged and then switches to bright green.
(I have tried it with another charger, same symptoms)

There may be a hardware cause behind the symptoms you cite, so a diagnostic
is recommended to see which parts are weak or failed in the computer. A visit to
an Apple Store with Genius bar may be helpful, as they can perform testing there.
A call ahead or use their web page, to schedule an appointment, is advised.
In the US and Canada, the Genius bar at a retail Apple Store can perform
a diagnostic service, for no fee, even on Apple products without AppleCare.
See links:
Apple - Concierge
Genius Bar - Apple Retail Store:
http://www.apple.com/retail/geniusbar/
List of Apple Stores, cities, countries:
http://www.apple.com/retail/storelist/
Also authorized Apple service providers who can test, repair and guarantee their
work should be able to handle an out-of-warranty older Mac, within age limits...
Ones too old for the Apple Store could be serviced at a Specialist, instead.

•Calibrating is part of maintenance, esp with older portables:
Apple Portables: Calibrating your computer's battery for best performance
•The power adapter can be problematic and cause issues, so there's this:

Also another item, other than keeping the magnetic connections clean of
debris, grime, and corrosion, is to check the MagSafe Board or have it
checked as part of a greater diagnostic. This board is behind the port
that supplies the computer and the battery with power from the adapter.
When it partially fails or if/when one of the connecting wires or plug fails
you can find odd issues or partial use. The battery may charge but it
may not be able to power the computer, and other odd effects.
https://www.ifixit.com/Device/MacBook
In older portable Macs, this was generally called a 'DC-in board' and as
such, you could read about it in an iFixit repair guide for the MacBook
model you have. These vary so the matching article is recommended to
see if that is something you may want to try. But I would have diagnostic
testing done and avoid additional damages from attempted DIY efforts.
There have been a few reports of other failure on the logic board that
contributes to a partial failure of the charging system, so about all this
may do is troubleshoot around the failure without finding an exact cause.
However it goes...
Good luck & happy computing!

Computer does not turn on, power LED goes off when power button is pressed

My Pavilion 17-e078nr has stopped working, it will not power on. When you push the power button, the power LED next to where the plug is goes off and takes several minutes before it comes back on. I've tried removing the battery and get the same results and with the batter in and AC disconnected the power button does nothing. I've also tried the hard reset with no luck. As far as I know, nothing has happened to the computer since last time it worked. My two theories are either the AC power is bad, or there is a problem internal to the laptop. The AC power is providing the 19.5V, I measured it using a multi meter, I'm just not sure if it's providing the required wattage, or if the connection to the laptop is secure, it feels a little loose, but at the same time the LED comes on, so I know it's getting a connection. Only thing I can think to try is go to a store that sells this type of computer and see if I can use one of their power supplies to power my computer, and/or plug my supply into one of their computers. Don't know how willing any store would be to allow me to do that though. Any one have any additional thoughts or advise?

Hi! I have the exact same problem... the LED on adapter, is very, very dim when connected.
At first I tried connecting my macbook to my roommate's adapter and had the same problem. then tried taking out the battery, and still had the same problem. I did the same thing with my roommate's macbook, but hers did actually turn on! it operated without the battery. Figured out it was problem with mine.
I kept on trying combinations battery, computer and adapter. turns our that my battery (which I thought at first was the problem) charges perfectly on my roommates mac, but wont charge on mine. her adapter won't work either on my computer. What I've been doing is charging my battery on her computer, then placing it on my mac, and it works. only thing that won't work is the adapter.
Went to a mac store, and they told me that the problem was a small cable o wire that went from the Magsafe point into the mac and that the LED was very dim because no energy was being drawn from that spot because of this little wire being broken. they gave me the name of this wire... very technical stuff so, completely forgot cause I didn't have anything near to write on.
I'd like to know if anyone has gone through this same ordeal, and had this wire replaced without any problems. When it comes to opening up my mac, I'm a bit skeptical, since warranty is expired and wouldn't want for a solution to become a bigger problem.

My iphone screen goes crazy when it charges

Hey there,
Whenever I charge my iPhone my screen goes crazy when I touch it. If i'm typing whilst its charging it clicks random things and deleted what i've typed. The phone works completely fine when its not charging and I haven't had any other problems with it. I have the iPhone 5c iOS 7.1.1 (about to update after this post).
If anyone could help me that would be great!
Ps. Someone posted a video and my phone does the same
https://www.youtube.com/watch?v=QbsNCjbs-xg

I have the same exact problem and I use an Apple charger and lightning wire cord. Resetting the phone doesn't work and neither does shutting it off and turning it back on. It is infuriating to say the least, especially because this stupid phone spends more time on the charger than off. The battery is crap.

MacBook Pro shuts off when unplugged.

For the past week my MacBook charger has been not functioning correctly. It only charged my computer when it was the the right position. I figured there was a short in the wires and was just going to pick up a new one. Last night however, the charger stopped working completely. I tried moving it around for about an hour until i just gave up and figured there was no hope. As soon as i shut the MacBook though, the charger light came on, but again when i moved the wire too much, it turned off. As soon as the charger light turned off, so did my MacBook. And i thought it was weird since there was still about 20% battery life, and it turned back on fine, but the date got reset to the year 2000 and it made me put in my wifi info again, which has never happened. I shrugged it off and really didnt think much of it though until it happened again today. This afternoon i plugged my Macbook in and it was and the charger was working fine after i found the right position to put it in. I let it charge for a few hours while i was out, and when i got home i used my Macbook for about two hours before i decided to move the Mac, causing my charger to move and stop working. And my MacBook imediately shut off again, exactly how it did the night before. What is causing my Mac to do this? How do i fix it? Its about 2 years old and this is the first time anything like this has happened to it! Please help me, I'm not good with computers at all so i have no idea what to do. By the way i dont think its the battery since when i turn it back on it runs just fine without being plugged in. It only turns off when it has been charging and then stops.

Borrow a friend's MagSafe Charger or try with the ones in the Apple Store. Sorry I wasn't clear from your post if you purchased a new charger yet.
Also clean the contacts on the MagSafe port and the charger side.
Apple recommends:
"Remove debris gently with a cotton swab or a soft bristle toothbrush, which provide the strength, flexibility, and precision for this task. Be careful not to get any cotton fibers stuck in the pin receptacle. You may use isopropyl alcohol to aid in cleaning the connectors as well. Be sure the connectors are dry before using the computer or adapter after cleaning."

Why does my iPhone 6 shut off when I charge it overnight?

I just got my iPhone 6 and now for the second night in a row when I leave my iPhone on the charger overnight as soon as it gets to 99% or 100% it shuts down and I have to hold the home and power button down to start it again in the morning. What's going on here?

Hi, Ek453.
Thank you for visiting Apple Support Communities.
I understand that your iPhone powers off when charging overnight. Here is an article that I would recommend going through when experiencing this issue.

Speaker off when sync/charge

Hi all,
I have a problem with my iphone 4 speaker. Everytime i hooked the unit to pc or wall plug for sync or charged my speaker goes off. No sound can be heard. Sometime it goes ok by itself, but sometimes i need to tap a little bit and this not solve the problem everytime.
I only be using it for 3 months. It is a common problem?
Thanks.

Thanks for the quick reply. Indeed I have the firmware version v200.21.118 and I have seen the Mute option when a call comes up. I immediately tested your suggestion, but it turnes out, it is not what I was looking for, for multiple reasons:
When pressed, the sound is muted in both the phone speaker as well as in the headset.
You need to perform an action before every call to enable the function, which is annoying.
There is still sound coming from the phone speaker.
Maybe I haven't specified my question properly, so to be as clear as possible: is there a way to have all the sound my phone makes (key strokes, ringtones, music) be played through the speakers of the headset and at the same time have the phone speaker muted?
