MomUnit Level 1 Level 1 (10 points)

My Lenovo ThinkPad T420s has 3 powered USB ports; two USB 2.0 and one USB 3.0.  All three successfully charge my iPhone and iPod Touch with both their original and aftermarket 30 pin USB cables. My husband's iPod 5 charged just fine on my PC with its Lightning cable.


However, the iPad Mini will not charge on any of the ports using either my or my husband's Lightning cable.  The Mini only charges from the wall outlet charger.  The Lighning cable works fine with any of these same USB ports for syncing... just not for charging.


Anyone else experiencing this, and any ideas?  Is something weird with the iPad Mini's charging system?

    It's probably charging but at a very slow rate. It'll be much faster when plugged to the wall socket.

    As I understand it, the mini will need more power than the iPhone and iPod. Even tho your USB ports are powered, its still not enough. It is charging but at a VERY low rate. Nothing wrong with your mini's charging system. Just the way it is designed.

    You kight consider buying the new charge adaptor for the latest ipad, it's a much faster solution


    Also check on your thinks pads update sites , some not all have an update to increase the power to the USB ports, producing a greater charge and considerable reducing the time ans frustration :)

    You are seeing excatly what Apple states can happen if you try to charge your iPad - any model/version of the iPad - using a USB port on your computer. This is copied from Apple's article about the iPad battery.


    There is nothing wrong with the way that your iPad is charging.




    Charging Tips

    The quickest way to charge your iPad is with the included USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port. When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge, but only when it's in sleep mode. Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.

    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.


    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

    How to Calibrate Your Mac, iPhone, or iPad Battery



    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

    In rare instances when using the Camera Connection Kit, you may notice that iPad does not charge after using the Camera Connection Kit. Disconnecting and reconnecting the iPad from the charger will resolve this issue.

    Like Diavonex said it takes more power to charge the iPad even the mini. If you use the USB on a Mac it has enough power to charge an iPad. However every none Apple PC I have plugged any of my iPad's into they don't have enough power to show that it is charging and takes a very very long time to charge them.

    I'm on my fourth iPad. 1,2,3 and mini. All have had same charging problems.  Varying speeds of filling up. I've always used the correct "matching" apple cables for all.  Have plugged into walls, USB"s and car. Completely irregular responses from one device to another, and even get differing responses from the same outlet at different times. All the nonsense apple puts out there about using a stronger charging USB, or not using wall outlets, or using certain outlets, I believe is a diversion from what they really know to be true: they can't figure out why devices charge at different speeds.  Does anyone else get irritated that apple protocol is that they DO NOT answer us if they don't want to?  All of these comment blogs are just that: civilians commenting on what they believe to be true. And we have to hunt through huge numbers of blogs and commentaries to even get near an answer!  With all due respect to you heavy-hitting top notch responders out there, thank you!  We'd be totally in the dark without you guys. But I've got so many dollars invested in apple product, as do so many users, you'd think they would offer the courtesy of answering users questions head-on, directly, rapidly and in a straightforward, easy to locate site.  It's insulting that they do not take better care of us. Yes we can call into express support for many issues, but they would not be of any help on this charging thing. What will they do? Recommend that we plug it into a different outlet and wait with us on phone for results?  Silly!  Whenever there's an issue about potential bugs in devices, apple support just goes away leaving all of us to guess! Why do I keep giving them my money?  !!!!!   Because I'm in so Mac-deep, I can't imagine converting everything to non Mac environment without losing my mind!  I really wish a bonafide apple support person would take on the challenge of answering why we cannot get effective consistent charging for iPads!

  • rolla9 Level 1 Level 1 (0 points)

    Simple....download and install Asus Ai charger software on your computer, I've been doing this since the original ipad!!

  • ritu9d Level 1 Level 1 (0 points)

    That was an amazing tip Rolla9 - Thanks... Asus Ai fixed my issue - now I have my iPad charging on my laptop.. Happy! Happy! Happy!




  • Vinod.R.Pillai Level 1 Level 1 (0 points)

    i noticed the same while connecying mu ipad-mini to my HP laptop..I-Pad  tells "not charging". So i kept the ipad in sleep mode for some 10 minutes , conected to the laptop. I found increase in battery charge ...Seems charging is very slow and only charges when the i-pad is in sleep mode..

  • sdc01 Level 1 Level 1 (15 points)

    Does that Asus Ai charger tool work on non-Asus boards?


    I am also very annoyed that I cannot charge my Mini on ANY of my computers. What a ridiculous notion that I must have separate charging and usage sessions (I use my Mini WITH my PC).


    Perhaps I can find a way to wirelessly interface to my Mini?


    BUT I can confirm that even though the Mini states, "Not Charging", next to the battery symbol... it will trickle charge (very slow) IF the Mini is asleep. Better than nothing, I suppose.


    This is obviously a design flaw. Please AFB's stop making excuses for Apple.

  • iSR5 Level 1 Level 1 (0 points)

    Yes, Asus Ai Charger works on non-Asus PC brands!

    I'm using it on 6 laptops (1x Compaq, 2x Toshiba, 2x Sony Vaio, 1x DELL).

    I've been using it since released, and I've never experienced any issue with it.



    Weeks ago, I plugged in my iPad mini, trying to sync it with iTunes, and I found out that the iPad was charging normally !


    I don't know if Apple did something on the recent updates on this thing, but I'm really happy, finally I can charge my iPad mini from my laptop !

  • Ralph9430 Level 6 Level 6 (14,350 points)

    The USB ports are providing enoug power to charge the iPhone and iPod but the iPad requires more poser and the USB ports cannot efficiently charge that device. Use the charger that came with the device and plug that into a known good wall outlet.
