  • Auto brightness not working in ios6

    I updated my iPad (3rd gen) to ios6, but when the update is complete i found that the auto brightness not working, when i use the ipad on dark room the brightness not changing, when i use ios5.1 it changing.. Any solution and actually the problem is on ios or in the hardware? Looking for help asap...

    Well my device is different and since it is a iPhone 5, it is not being updated to iOS 6 but the issue is exactly the same. From my mind this could be up to software but also could be from an hardware issue. The thing is that even if it worked before iOS 6 for you the new software could have revealed hardware conflicts since the software interacts different with the hardware for some features. This would be the worst case scenario because I know that normally iPhone 4 devices if not the 8GB model will be out of warranty. For me this is just a small issue since my warranty is still one year :(
    I have contacted apple care for this issue and have get the info that it will be escalated to the engineering team, for further investigation. As I know there was also an issue with some proximity sensors at the beginning if the iPhone 4 models and I think there was an software fix for a lot of them. Hope for the best!!!
    I have also done a lot of Troubleshooting, reseted settings, content and settings, restored in dfu and recovery mode, restored with new .ipsw (iPhone OS), restored on different pc (so even this step gas downloaded a totally new .ipsw file), first on a Mac!
    Next step wis that I will let the battery drain low entirely, a Troubleshooting idea of an friend. This might empower the entire hardware for a restart. I am not really believing in this step but I will give it a try :)

  • Auto brightness not working on iPhone 5?

    On the iPhone 5 - In the settings, when flicking the auto brightness on/off the screen shows no change in brightness - whether in a completely dark room or with the lights on etc. My iPhone 4 has been updated to IOS6 and seems to be working normally (brightness auto adjusts in all situations).
    Anyone else have this problem of the auto brightness not working?

    There is nothing wrong with the auto brightness.
    When you have auto brightness enabled the slider works as the minimum brightness setting with auto brightness.
    If you have the slider too high the brightness cant reduce because youre not letting it.
    Set your brightness at about 25% and you'll see what I mean.

  • Lenovo b570 Backlight not working

    Hi all,
    Had a few problems with my b570 (think the hard drive might be screwed)
    But tried to wipe it all and start from fresh, and after not being very successful left it alone for a few months.
    Im trying to have another go at fixing it now and the backlight on the screen is not working, there is no real reason for it to have stopped working as it hasnt been moved in months, the screen is still working but is very dark if i get real close i can see what it says.
    do i need to replace the whole screen or is there something i can do to maybe get it working again?
    Thanks

    hi robk87,
    Welcome to the Lenovo Forums.
    If you get the no backlight issue after you turn ON the computer and adjusting the brightness (via Fn + up/down arrow) have no effect then you may need to replace the entire screen.(looking at the spare parts, the B570 uses a LED-backlit LCD display - these types of display doesn't have an inverter which powers up the backlight).
    - Link to picture
    - Sample item
    Video Guide:
    Lenovo IdeaPad B570 Laptop Screen Replacement
    Alternatively, you can try using an external monitor and connect it to the VGA or HDMI port (selected models) to get a display.
    Hope you get the computer fixed soon.
    Regards

  • Lenovo AIO C440 - not working infrared remote control

    Hello,
    is there any hint how to get infrared remote control working for a new C440 model? Tomorrow I will try to measure and/or replace batteries which could be bad. For now it is totally not working.
    Another question: the remote should work only within AverMedia TV app or in the whole Windows 8?
    Regards,
    Zdenek

    hi bohdik,
    Welcome to the Lenovo Forums.
    The IR Windows Media Center remote control is for use with C440 models with optional TV tuner. If you have this model,  make sure the TV Tuner driver and the ITE CIR Driver from the lenovo support site are installed under Device Manager (press Windows Key+R then type devmgmt.msc) then follow  the Set up a TV signal in Windows Media Center. guide.
    Note:
    You must have Windows 8 PRO to enable Windows Media Center
    See this articles in reference:
    How to add Windows Media Center to Windows 8 Pro
    How To Install And Set Up Media Center On Windows 8
    Hope this helps

  • My new Lenovo IdeaPad N580 not working well :(

    Hello, I have a Lenovo IdeaPad N580 with build-in windos 8 OEM. I got from my uncle, came from abroad. now a days it does not wark as well. Problems, 1. Sometimes touchpad seems to be hanging when I working. But with external usb mouse it works fine. 2. Some keys are not working like u, k 3. When my system run first..... If I doule click on any icon in desktop to open it...... It accept the command as "Delete"... I seems just I want to delete the icon.... by the way I want to open the program/drive. When the hidden command is executed..... I find the icon/folder/file anything in "Recycle Bin"..... and command seems to be unlimited (multiple times).... My observation in this issue: System might be work in self!! also in Windows "safe mode" I tried to fix up it by "System Recovery" and "System Resetting". But no result Please help me to fix the problem Regards, P Delwar

    Bring all the express to the same room as the mac you are using to setup the network..
    One by one, plug them in and do full factory reset on them.. they should then show up in the Airport utility as Other Wi-Fi devices (1) and you can select them and continue the setup.
    If that fails try using the airport utility on ipad or iphone as they are far less problematic than Yosemite in particular.

  • Satellite M35 - Brightness Not working with WXP SP2

    After formatting and installing XP SP2, Brighness function keys do not work. Can anyone please point me to what type of drivers I need to download to get the Brightness working? I tried to install Power Saver from Toshiba site BUT I get error messages. Nto sure if this driver is for Service Pack 2 of XP.
    Any assistance you can give in getting the M35 Satellite Brightness working with XP Service Pack 2 would be appreciate.
    Thank you in advance.

    If you dont have Tools & Utilities CD please check Toshiba US download page and there you will find everything you need.

  • Lenovo finger print not working

    Hi,
    Lenovo finger print suddenly stopped working last week on my laptop. Further to this while looking for solution i came across the new update available on suppport and download page for my system (3000 N200 0796) (http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-67845).
    I unintalled the lenovo finger print software and intalled a new one from above update link.  
    But still its not working. When i open the finger print reader i get a message saying "Failed to open the sensor" and when i try to access it via client security solution i get message saying "device is not installed"
    Further to above i checked the device manager and there is no option for finger print. I thenk checked BIOS and found that under security option ther is also no option of finerpring..!!!
    I think deleting the old software completely and downloading was not a good idea..
    Does anyone know how to get the fingerprint option back into bios??
    Message Edited by Dhaval on 22-05-2009 03:48 PM

    Hi,
    I haven the same problem once I uninstalled Vista and installed XP SP3.
    I was able to resolve this by following way:
    1. I found in the device manager "AuthenTec Inc." device under the Universal Serial Bus controllers.
    2. I opened this device and pressed the "Update driver" in the 'Driver" tab; then I installed the driver for the fingerprinter.
    3. As result, the system recognize this device as Personal indentification device; and fingerprinter works properly.
    Please let me know if this was helpful.

  • Lenovo care button not working

    hi..
    I've just downloaded windows 7 and my lenovo care button doesn't work
    I tried to download all the old drivers for xp but half are not working and I still can't get the button to work..
    I want to resort my hard driver to its original factory state but can't because when my laptop starts up I can't press the lenovo care button to interrupt the start up..
    I don't know what to do.. I want my xp back...
    can someone please help me!!

    Did you make XP restore disks?
    If not, you may need to buy them from Lenovo,
    or get a oem copy of the same version of XP
    and install using the COA code on bottom of laptop.
    You will also need to download all drivers.

    hey Giorgi,
    welcome to the forums.
    uninstall the current USB drivers and let windows install its generic drivers.
    test the usb port with a memory key. can it get detected? if yes, test our your iphone as well as the printer.
