IPhone 4S doesnt show charge symbol and charges very slowly on brand new MacBook Pro. Not recognised by iTunes. Charges fine on Asus laptop. iPod charges fine on Macbook Pro...
Hi!
I'm trying to fix a problem I'm having with my iPhone 4S and MacBook Pro.
I did manage to connect it initially and set it up with XCode as well as iTunes.
Today I have spent two hours trying to connect it to my MacBook Pro and I have so far found the following...
iPod 2G - charges from MacBook Pro, Wall Charger, Asus Laptop (works with both my Apple USB cables)
iPhone 4S - doesnt charge from MacBook Pro, but does from Wall Charger and Asus Laptop
- Asus Laptop running Linux Mint recognises the iPhone as a device with 'lsusb' and you can browse photos etc
- MacBook Pro doesn't recognise the iPhone as a device with the 'systemprofiler' equivalent of lsusb
- Interestingly, despite the charging icon not showing, the iPhone either maintains charge or very, very slowly charges
when connected to the MacBook Pro.
Any ideas as to what might be wrong? I've tried both the USB ports on the MacBook Pro and no difference. I've tried the 6 ports
on my old Asus laptop and they all work fine!
Thanks for your help!
OK.. Went to the Apple Store - they could either book an appointment with a Genius.. or send the phone for
testing and repair. Found out I have a 2 year warranty on it so have a year left.
My research has led me to assume that the USB 2.0 function of my iPhone was faulty from the day I got it (it kept disconnecting the reconnecting but transferred data fast), but soon stopped doing that and ran at about 1MB/s - USB 1.1 speed - and has done this ever since.
The MacBook Pro somehow is trying to use the USB2.0 function and is not letting the phone fall back to USB 1.1.
To test my theory I found an old USB 1.1 hub... plugged it into the MacBook Pro... then plugged the iPhone
into that. Job done. Charging fine, recognised every single time I connect, and only took a few secs to send over my XCode app to the phone and runs fine! I guess this works as the hub forces the iPhone and MacBook both to USB1.1 mode which then works fine! Will just use it like this for a few months then send it in at an opportune moment (want to get some apps out before I lose my device for repair for a while!)
I will in the next week or so test my iPhone on my friend's MacBook Pro (we bought them the same day but I didn't get the Retina cos I like to be able to upgrade RAM, Hard Drive, and replace battery when it wears out). I will also test their iPhones on my MacBook Pro to see whether it really is the phone or the MacBook!
PS I will get WiFi Sync running since transferring 60GB of data over USB1.1 won't be fun... will do a full factory reset on the phone just in case there is an issue there - will post results of this too!

My older mac book pro and iMac are both running 10.6.8 and both have started running safari and email VERY slowly. My new mac book pro running 10.9 is having no issues. Is anyone else experiencing these issues?
No noticeable speed differences running the four latest OSs on my machine.

my iPhone 4 will no longer charge. It is also not recognised in iTunes. There seems to be a problem with the connector slot. I've tried other cables and other computers/plugs but the connection is not being made. Any suggestions?
It seems to me that the connection port is faulty.
GeorgeLooks like a Visit to an Apple Store or AASP (Authorized Apple Service Provider) is the Next Step...
Be sure to make an appointment first... -
IPad not recognised in iTunes and showing not charging from wall charger
I have had my ipad a year and today it is not recognised in itunes, also when charging from a wall socket 10A ipad charger it shows Not Charging (however trickle charges). I have tried resetting (holding both buttons for 10 sec) with no benefit, i am reluctant to resset everything as if this does not work I have a dead iPad.
No other items have changed and there does not appear to be any visable damage in the conector on the iPad, note an ipod conects in itunes, so it is not a Mac side issue. This feels like a software issue on the iPad.
Any help appreciated if anyone else has had this issue.
ThanksUpdate: Apple agreed to a replacement iPad even though I did not return faulty one to dealer till 2 weeks outside of warranty. The replacement looks brand new. Dealer told me Apple does not repair iPads as they are a sealed unit. I am doubtful that is true. Suspect they do 'refurbish' and use as replacements. Am grateful to Apple for the new iPad. Two thoughts as to why they agreed to it despite faulty one out of warranty: 1) Consumer Guarantee Act in New Zealand - which trumps manufacturers warranties and says among other things that goods sold must be of an 'acceptable quality' (and I did mutter to the dealer about the CG Act); 2) It stops owners blabbing on forums like this what component failed on their iPad... and hmmm maybe Apple recognises a problem with the lifespan of the dock connector/cable.

My iPhone 4 died and I have tried charging it and plugging it into the computer, but nothing happens execpt the dead battery thing that pops up when you charge it when it's completely dead.
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

my iphone 4 doesnt show up in itunes. it is also locked on the 'connect to itunes screen' when unplugged from the computer. help me!
Close your iTunes,
Go to command Prompt -
(Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
(Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
In the "Command Prompt" screen, type in
netsh winsock reset
Hit "ENTER" key
Restart your computer.
If you do get a prompt after restart windows to remap LSP, just click NO.
Now launch your iTunes and see if it is working now.
If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

My iPad mini won't charge at all. I got it for Christmas off my dad and it is still in brand new condition. Until the other day it has been working fine but until yesterday or the day before my charger went all funny. In order to charge my iPad mini you had to put the charger in an exact place and if someone so much as touched it it would stop charging because it wasn't in its exact position. But today I tried to charge it again and I tried getting it in the same spot as yesterday but it is not working at all. I have only ever charged my iPad mini in the wall but I have seen posts about people charging it in the USB in an computer. So I thought I would also try that but that hasn't worked either and now my iPad mini won't charge in a plug or USB and I live really far away from an apple store and I can't get a new charger also because I live far away from the store. So what shall I do?
When and where was the iPad/charger purchased? It's covered by a 1-year warranty.
The problem may be the USB cable.

i upgraded new software onto my iphone 4 however it stopped syncing and said error so when i tried to access my phone the itunes USB was showing in my phone screen and now i cannot access my phone
When it stopped and said error, what was the error? You are saying that you disconnected the phone from the computer and all you see is the USB showing on the phone? Then you need to reconnect to the computer and restore the phone.

IPod touch frozen on screen showing apple symbol and usb cable.
Pod touch frozen on screen showing apple symbol and usb cable. Happened during a update attempt.
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again. -

My ipod 5th generation charges when connected to my PC but not recognised in itunes with windows 8.1
Why is my ipod 5th generation not recognised in itunes in windows 8.1?Connection to my PC only charges the battery.
Did this iPod previously work with this computer (running Windows 8.1), and does not now for some reason? Or is this the first time (or the first time with Windows 8.1)?
The fact that only the battery charging symbol appears on the iPod screen seems to indicate that the iPod does not recognize a data connection. It's like you are connecting the iPod to USB (wall) power adapter. It is likely that the Windows system also does not see the iPod as a connected device; you should confirm by looking at Device Manager.
You should rule out a faulty USB docking cable. The dock connector has separate connection points for power and data, so it is possible for it to connect to charge the battery but not connect for data. So, if possible, try another docking cable, or try the cable you have with another Apple device.
You should rule out a problem on the USB port. If you connect something else to the same port, does it work properly? Preferably, you should use something similar, like a USB flash drive or port-powered external drive, and try copying over some large files.
If the USB port and docking cable are OK, the cause is more likely to be on the iPod (such as a dock connector that is worn out from use). -
My brand new PB will not charge when in standby or when on
I played with a number of PB's so far and finally have my own but... My brand new PB will not charge when in standby or when on; as soon as I plug the charger into the USB port it detects it and brings the screen up (if in standby) showing the lighting bolt on the battery but it does not charge; the lighting bolt stays but the % charge does not change (or hopefully increase) at all; it will actually decrease (??); the only way I can charge it is when I attach the charger and the PB is powered off… the PB brings the red (or green can't remember) LED on and starts to flash it on off and charges; tried the hard reset with no change; I am running the latest OS release 1.0.8.6067. Has anyone seen this? Is it h/w or f/w? Any Fix?
Here's a final update on this... the units goes back to its maker or the store sometimes tomorrow... Why? First I tried to understand if this was s/w or h/w related or maybe both before calling support which in the end I did; so I did try a different charger, hard resetting the unit, discharging and recharging etc; nothing helped or fixed the charging in standby; the unit continued to charge only after being turned off and then plugged into the charger. Here's what I learned:
1. Going through the initial setup and OS update it is quite possible for the unit to NOT load the OS image correctly i.e. it appears that it loaded the OS and displays the OS version as if it loaded properly when in fact it did not and the image loaded is corrupt. I found this out during a live session with support when they were looking at my PC screen while the PB was connected to the PC only to point out that the Desktop Manager was showing a s/w update being available (1.0.8 bundle 6067) while the unit was reporting 1.0.0 bundle 0. Strange, I thought I already had 1.0.8.6067... after accepting the update, which takes a bit to load, I started more testing, charging, discharging, hard reset (i.e. Volume Up + Power) etc with no positive results to report. This also proved that the USB port is working, both data (PC to PB communication alright) and power (PB displays the plug over the battery bar when the power contact work)
2. The charger I have works and it is the correct one: P/N PSM09A-050RIM; make sure it is not one of the incorrectly rated chargers some received.
3. In order to reduce the amount of current the unit consumes when on, you have to run the Video Chat app at least once and acknowledge the (c) page; otherwise this remains as a background app that take more CPU cycles on the battery. After doing this I did notice a slight improvement in the sense that PB did charge some instead of discharging. The problem is that it only charged to about 60% and did not move higher no matter how long I waited (yes I did reset just to make sure it is not the s/w acting up and deciding to not update the power bar)
4. The way the RIM RMA works is like this: they start the process for you to return the unit back for repair which I understand may take 10 days; you may get a unit to use for this time if so desired, it will be charged to your CC; your unit may get repaired if possible; if not possible to repair, your new unit will be replaced with a refurbished unit; once you get some unit back you need to send the “10 day replacement unit” to RIM to get your CC charge cleared. I find that this program is good for when you can not return the unit to the place you purchased it from. Otherwise it is not good as I do not like getting a refurb for something I consider brand new (not to mention that you may get a unit with a few bright or dark pixels)
5. Throughout this process I looked at three (3) Playbooks: 2 had bright pixels and were returned immediately; this last one does not charge correctly. No win for me!
6. The battery lasts approx 4 hours with the unit playing a video clip in a loop and WiFi on with a WEB pulled stop watch running as well (had to allow multi tasking in setup/general).
Finally, my theory about this problem is that it is h/w related and that it is caused by the noise the board or the display is making when the unit is either on or in standby; a component not soldered properly (cold joint) or out of spec may be the culprit; for example a resistor in resistor divider monitoring the battery voltage or a decoupling capacitor missing or not soldered...
