  • LENOVO K3 NOTE ISSUE-BATTERY DRAINING FAST AND USB PROBLEM!!!!!!!!

Hope, i can get a solution from this portal Battery is also draining fast after this bug has started.  Thanks in advance.

    since many people reporting the heating issue. 
    i would like to ask you a favor to help me to do a experiment. 
    i am not sure if you guys know we have a feature called "background app management", it can restrict background tasks to block them consuming current drain.  The heat could be generated by drain consumption. 
    the feature is at Settings->Power manager->Background app management. 
    I made a video shown at below link:

    Everything that you sync to the iPad is done through iTunes or from downloading from the cloud if they are iTunes purchases or through iTunes Match, if subscribed.
    It is also not possible to transfer music or certain other files though Bluetooth between other iPhones or Android devices. You can transfer between iOS devices, pictures through devices that are Airdrop capable.

    i tried to sync my ipad to my itunes using usb but it will say not charging,, i can sync with my ipod touch without any problem... please help..

    From http://support.apple.com/kb/HT4060 :
    The fastest way to charge your iPad is with the included 10W 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. 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.
    iPods need less power to charge them (their wall charger is half the power of the iPad's, 5W as opposed to 10W), so are more likely to charge via USB

  • New USB Problems - USB Device Not Recognized

    I've had Ultimate x64 installed for awhile now.  It's gone through some growing pains (mostly NVIDIA-related BSOD issues) but it's usually pretty stable.  About a week ago it started having USB problems.
    I have a SanDisk ImageMate USB 2.0 card reader that suddenly stopped reading my camera media.  I also have an HP photosmart 7960 that stopped printing (I was using drivers for another printer, per instructions from HP, because this printer doesn't have Vista drivers).  My Memorex flash drive also no longer works, and it no longer sees my Garmin GPS.  They all say "USB Device Not Recognized".
    I contacted HP and they determined that my USB needed to be rebuilt.  This is what I did:
    Unplugged all USB devices.
    Removed all related USB software.
    Booted up in safe mode and went to Device Manager and uninstalled, in this order: USB root hubs, then USB host controllers.
    Even in safe mode, I couldn't get everything to stay deleted.  As soon as I deleted a USB host controller it would reinstall itself and install a root hub.
    I rebooted, and now I'm trying to install the SanDisk card reader.  It installs it, and then there is an exclamation point next to "USB Mass Storage Device" in Device Manager.  I've tried to update the driver (also by having it look in C:\Windows and all subfolders) and it says "Windows was able to successfully install device driver software, but the driver software encountered a problem when it tried to run.  The problem code is 10."
    So I seem to be stuck with no USB.  I've been throwing new hardware at Vista, determined not to go back to XP.  However, I'm sure I can't work without USB.  What should I do at this point?
    Thanks!

    WHY hasn't anyone replied to this thread?  This is a huge issue, and I am certain millions are affected.  Glowball, did you find a solution.
    I have had major issues with my PC Card (PCIMIA SLOT) Adapter TYPE I & II Compact Flash Card Readers, which were plug and play in XP, give the same behavior - now you see it , now you don't!  None of the manufacturers were willing to provide any acknowledgement nor certify their devices for VISTA.  However, on the MS Support site I did find the attached instruction for a Reg Edit which allows the assignment of an IRQ to the PC Card Adapter in VISTA - apparently this was not required in XP (is this an advance in the OS??? I think not!).  IRQ 16 was assigned, and now works great on my Vista Home Premium laptop.
    On my other Vista Business laptop, I have a PC Express Cardslot - haven't tried an Adapter for SD + cards yet there, but supposed to not have the same issues, I believe.  However, I am having the same issue Glowball describes above with my USB  Card reader. It is USB 2.0 high speed certified and has been working great for Readyboost with an 8 GB SD card inserted and adding 4 GB of Readyboost "ram".  However, when I also inserted a CF card into the adjacent slot of the same card reader, it has become an "unrecognized device" as noted above.  Tried unplugging, replugging USB cable.  Although still displayed in My Computer and Explorer, the drive contents are not updated or active and cannot be opened - get "drive not present error" and the USB error noted above.
    I am unwilling to delete the USB drivers/device EVERY time I need to work with a CF card.  Surely there is a registry correction for this issue.  It must also tie into this IRQ issue noted with the PCIMIA card readers above as well?
    Anybody know or CARE?

  • TX2000 USB Ports, Digitizer and Webcam not working (several people have save problem)

    OK folks this is an old problem that was posted on the old TX/TM board:
    http://h30434.www3.hp.com/t5/TX-TM-Series-Notebooks-Reply/tx2000-usb-ports-digitizer-webcam-all-not-...
    Several of us have had these ports/hardware fail. 
    ****IT IS NOT A BLACK SCREEN FAILURE******
    In my case, the motherboard has very low hours after replacement, full system reinstall, all drivers up to date.  If you take the time to read all three pages, you will see that many of us have tried everything that anyone suggested.  Most of us still believe that this is a software issue as opposed to a hardware issue.
    Not much hope for a soulution, but thought I would try this board since the TX/TM board is now reply only and probably has a very low visit rate.
    Jim

    I also am not able to use the pen and touch features after doing a recovery manager to factory spec, everything else is good but like the others when trying to open Tablet Properties it gives the message a supported  tablet was not found on the system, also after updating the digitizer from hp the version does not change it's still 6.1.6002.18005 when it's supposed to be 5.05-5_HP5 Rev.A.
    I've unblocked the download in properties ran it as administrator,uninstalled the old driver, my USB works my Quick launch buttons work, the screen rotates, the bios is updated. ran HP Update it finds two updates -a HP update software utility and a critical update HP Photosmart and then nothing else when there are many many more at the software and driver page for the TX2000
    Is HP being silent due to the class action lawsuit? Was that a perk that hp got for settling, that they no longer have to address any issue with this Tx2000 series?
    As so many have wrote before...... NEVER AGAIN HP!

  • ThinkPad USB Keyboard with TrackPoint -- Buttons not working (SK-8833)

    The buttons on my trusty Thinkpad USB external keyboard (SK-8855) have suddenly stopped working properly. The right-hand button has ceased functioning most of the time, and now the middle button both scrolls windows (as it is supposed to) but also acts as the right-hand button (showing context menus, etc.). Also, occasionally, the left button stops working too, until I click on the center button, and then it will work fine for a while. There is no real consistency except that they are inconsistent.
    The rest of the keyboard, including the trackpoint, works fine, but the fault happens when the keyboard is plugged into two different machines--my Thinkpad T430 and my Thinkpad x100e (the very first time it was ever plugged into this one).
    I would be happy to see if some dirt has clogged up the button mechanism, but the keyboard is still under warranty and one of the screws is under a label (I think). It looks like some kind of hardware issue since I haven't changed any software on my system, but I guess it could be a driver problem, but Lenovo has made it all but impossible to find the drivers of this keyboard.
    Does anyone have any ideas, or should I just be contacting support for a warranty repair?

    You should get the keyboard changed under warranty.

  • Printer driver and USB problems

    Hello,
    I have the Photosmart C4780 printer and scanner, and have been running into issues. My computer (vaio duo 13) runs Windows 8.1 64-bit. 
    When I connect it by USB, a message pops up saying that Windows does not recognize the device, and that it has malfunctioned. I thought it might be a driver problem, so I downloaded the PS_AIO_06_C4700_140_408 file. After clicking it, it would start extracting, but would exit as soon as it hits 100%. I waite for at least ten minutes, and no further windows came up to continue installation. I did this a couple times, all with the same result. The simple driver does not work either, and the Print and Scan doctor just tells me to download the file I mentioned above. I also attempted to reinstall, but there were no files that I could find for the printer.
    I am at a loss for what could be the problem. Any help would be much appreciated!

    I have exact same problem with Lenovo Yoga 11s.
    Driving me insane, and printer will soon be dispached through my window.

  • T60p USB problem

    I have a very simple T60p USB problem. It's very repeatable, using a T60p (2613 ETU) and Windows XP it will not flash upgrade the OS on a Windows Mobile device, a JasJar.
    Perhaps this relates to the T61 USB problem, perhaps not. I have also noticed that when two Verbatim Store and go 8 GB memory devices are attached the T60p has problems with them when booting. Plugging just one in is not an issue, when booting with both plugged in creates a problem where the driver fails to load. Plugging either or both in after it has booted is not a problem.

    There are reports that static buildup between the laptop and the dock, can cause unexpected crashes, there is an official remedy which you can obtain from Lenovo for free if the dock is still within warranty, or use aluminium foil in the place of these rubber caps.

  • USB problems since EFI firmware update 2.6

    My MBA has been suffering USB problems since this update.
    I have an IOGear USB 3 GUH374 hub.  I connect my iPad mini and USB 3 disk to it.
    Since the update, the iPad has stopped charging through the hub.  Now, I can't find the power specs of the hub, so I don't know that it should work, but it was working fine.  Now, the iPad says "not charging".
    The USB disk has spontaneously disconnected a few times, with the system reporting that it was improperly disconnected.  One time, the disk was corrupted.
    This could be a coincidence, so I've contacted IOGear.  But, I'm also having new, different, sleep problems with the MBA and Mountain Lion.
