Windows 8 problems in Lenovo G475

Hi there! I own currently a G475 laptop, that previously ran Windows 7 Home Basic, but now runs Windows 8 Pro. Here is my situation, I have 2 problems.
1) I cannot change the brightness on my computer, I tried a cmd scan as administrator, no luck. Tried Lenovo Energy Management software for Win 7 and 8 version, no luck either. The brightness is stuck in the lowest settings, and I don't know what to do...
2)Onekey Recovery doesn't work either, it says it cannot start and that I need to reinstall the driver... Even though it is installed in C drive, with it's Lenovo partion of like 25 gb... And the Nova button doesn't boot into the OKR menu, it boots straight up to Win 8.. I already tried to reinstall it, but no luck either...
Honestly,  I love Windows 8, but these 2 bugs make me frusterated!!!! Please! I am seriously thinking about reverting back to Windows 7, but I need Onekey recovery to revert to Factory settings, since I still have the hidden folder with the factory image in it.
Any opinions???
(P.S: The hotkeys don't work with the Windows 8 version of Energy Management...) Will I need to reinstall my Windows 8?
Solved!

hi Chase23,
Can you try the following:
1. Install the latest ATI drivers and adjust the brightness and contrast using ATI’s Catalyst Control Center. If this doesn't work, can you try to immediately press Fn+Up Arrow to increase the brightness before the unit boots into Windows 8.
2. The One Key Recovery button and the OKR feature will no longer work if you upgrade from Windows 7 to Windows 8 - see this Windows 8 Upgrade Guide by Lenovo
If you're thinking of restoring back to Windows 7 but the OKR button doesn't work and you didn't create a recovery disc using this method then you will need to contact lenovo on how to obtain a copy of the recovery disc.
Hope this helps

  • Lenovo G475 - Driver WLAN compatibilidad con Windows 10

    Ayer actualice a Windows 10 mi notebook G475 no hubo ningun problema. Despues de actualizar noto que no me agarra el wifi y no me apace en ninguna parte. Busco el driver guardados en el disco duro y cuando se instalando me dice que no es compatible. Le puese la opcion compatibilidad con windows 8.1 que era mi version anterior y nada.  Checo en la pagina de lenovo en la seccion descargas y no hay soporte para windows 10. Como haria en este caso, gracias...

    Hola,  Yo tengo el mismo problema, tengo una G475 y mi tarejta de red WIFI es la RTL8192DE apenas hace unos días actualicé a Windows 10 y no funciona el controlador, ingresé al panel de control/adminitrador de dispositivos y traté de actualizar pero dice el sistema que cuenta con el controlador más actual y aún así no funciona, así mismo ingresé a la página de Realtek para buscarlo (http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PFid=53&Level=5&Conn=4&ProdID=309&DownTypeID=3&GetDown=false&Downloads=true) y no tiene una nueva versión. ¿Alguien puede por favor compartir el driver para descargarlo? Gracias. - Geova Cabrera.

  • Lenovo G475 Windows 7 to Windows XP

    First sorry for my english, i buy a Lenovo g475 on December 2011, it came with windows 7 starter but i want to know if i can change to windows xp it will lose the warranty because i extend it 2 years more i want to know if i lose the warranty i want to change it because i dont like windows 7 starter and because i cant run a lot of games because it takes more memory and that so can you tell
    ¿If i change Windows 7 starter  to Windows XP it will lose the warranty?

    Hi and welcome to the forum!
    No, you won't lose warranty if you install Windows XP on your notebook. But do make sure you burn a set of factory default settings through OneKey recovery: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?DocID=HT051302

  • Windows 7 RTM, Lenovo Y 550 explorer problem?

    I just installed the Windows 7 RTM onto my Lenovo y550 and successfully installed every driver.  When I open up any window or program and minimize it, I cannot click on any icon or the desktop. If I click Show Desktop at the bottom right, I can then interact with any icon and the desktop just fine. 
    I have tried uninstalling and reinstalling the graphics card driver but it did not resolve it. I also noted that with the graphics card driver uninstalled, the problem is still present. I reinstalled the chipset driver and reinstalled the graphics card driver again but to no avail.
    If you end the explorer.exe process and then restart it, the problem is still there.
    Any help would be appreciated!
    Solved!

    Just wanted to update for anyone that might run into this problem; the Lenovo OneKey Theatre was the problem. After disabling the program out of Msconfig, the problem went away. 

  • Error In Installing Windows XP in Lenovo G560

    Hi,
    I am using lenovo G560 with Windows 7. Now i don't want to use it any more. so i decide to install Windows XP like normally in Desktops as i had used desktops only.
    Boot from CD and windows Set started with loading files....in middle it stops by showing Blue Screen of Death I am not sure about it why is come.
    Please suggest how to install Windows XP to replace windows 7 in lenovo G560
    Solved!
    Go to Solution.

    Hello everyone!
    I am using Lenovo G460, i guess it is not that different from G560 for the purposes of this discussion.
    I had the same problem with a blue screen. I changed settings in BIOS from AHCI to Compatible and installed XP. After that I updated BIOS from within the XP, installed all the drivers, including the AHCI driver from Lenovo website.
    Then, I go back to BIOS and change settings from Compatible to AHCI, and I get the blue screen again.
    Ok, i don't know anything about NCQ and hot swapping, which I read about on wikipedia, and which i suppose are supported by AHCI, but my question is:
    Should i now always stay with my settings as Compatible in BIOS and, therefore, never be able to use such features as NCQ and hot swapping? I repeat, that I don't know anything about AHCI or Compatible mode, but I figure that AHCI is better.
    Please help me in finding the answer, whether to stay on Compatible and forget about AHCI, or may be there is some way to solve the problem for XP users with AHCI mode.
    Thank you very much.

    Hi,
    You are getting the error because the printer name is greater than 40 characters.
    The SAPLPD can only recognize printer names with 40 characters or less.
    From the log, i believe you are using the printer BKC_7THFLR_HPCOLOR3800 ON THMUMGDCPS01 (FROM BKCDT1017) IN SESSION 11
    but the SAPLPD is recognizing only till BKC_7thFlr_HPColor3800 on THMUMGDCPS01.
    Try to change the printer name .. it will work

  • Strange problem with Lenovo S650

    I have an interesting problem with Lenovo S650.
    If it stay in 2G/3G mode - it connect and work in 3G network well. But if I put "only 3G" mode, it don't connect to the 3G network.
    I changed SIM-cards, modems, firmware, mobile operators -  Nothing change.
    What is the problem? Thank you.

    Because your network needs both 2G and 3G to establish an internet connection. When the signal is low ,3G is favored/preferred (WCDMA Preferred or Auto )...but that uses more power. Don't actually need 3G all the time.
    This isn't the root of your problem ...Actually isn't a problem at all .
    Now can you tell me your firmware build number(Settings>About phone.. ) ?
    Did you had this problem from day 1?
    Did you get the phone from China and flashed the ROW firmware yourself? Got the firmware from some Russian forum and changed some regional code at the first boot...by any chance?
    Beside flashing different baseband modems, have made other alterations (Like changing engineering mode settings... )
    Thanks

    Apparently our Sandbox system didn't have a Spool server configured. That's why the error. It works perfectly in other systems.
    The output device's Host Printer must be defined on the spool server for saplpd to recognize. Otherwise you see an error.

  • Nested Window Problem

    Hopefully someone out there can help solve this one.
    How do you get a child window to automatically resize within a parent
    window?
    On their own both the child window and the parent window behave as
    expected but once we attempt to load the child window into the parent
    window the child window is sized to some unknown but excessively large
    size.
    Can this be solved with some creative use of parent size relationships
    or do we have to programmatically size the child window?
    Any help/comments/suggestions would be greatly appreciated.
    Sincerely,
    Sean G. Germain

    Glen,
    Thank you for the prompt reply.
    We have already done what you suggested (My explanation was not very
    clear ... sorry) to no avail.
    Any more takers and/or ideas anyone?

    You may need to dynamically tell the child window what its parent is (such
    as a named grid that exists on the parent window). Setting the child
    window to size to its parent should work once the child window knows who
    its parent is. You should be able to put your window into that grid at
    specified row and column coordinates. To reset the parent and position a
    widget in a grid, you do something like the following:
    <Widget>.Parent = NIL;
    <Widget>.Row = 1;
    <Widget>.Column = 1;
    <Widget>.Parent = <TargetGrid>;
    I believe that you should be able to do the same thing for a window, too
    (using "Self.Window" instead of "<Widget>").

  • Running Worldcraft with Wine (or OpenGL in child window problem)

    Hi!, I'm trying to run Worldcraft (the Half life map editing tool) with wine (version 0.9.30), everything works fine except when I choose to display a 3D view on one of the viewports  (3D views uses OpenGL to render the scene), when I do this, the whole window turns black, and flickers (showing some portion of the original window) when I hit the mouse button of move the window.
    This seems to be the Opengl in child window problem that was supposedly fixed in wine 0.9.28, but, well.. it happens    This happens also with Lightwave 8.0.
    Can anyone try and see if this happens to you as well?  or.. well. does anybody knows how to fix it?
    thanks a lot!
    silencer

    Thanks Nephastos, but I'm trying to run Worldcraft, not Warcraft Worldcraft is a world editing tool for Half-Life.
    I uploaded it to my server if anyone would like to try and see if it works for you (as it is an issue that should be solved by now, I think),  you can download it from http://www.darkdesigns.com.ar/worldcraft3.exe

  • Failure to search - query window problem

    Hello again,
    Have anyone of you came across a problem with SAP search mechanism in query window attached to document field? I've created a simple query of "Select acctcode,acctname from OACT where acctcode like '2%' and postable='Y' order by acctcode" and attached it to one of document fields (doesn't matter which one). When I run this query a usual window poped up with a search field on the top, but when I typed "2" in it, selection bar moved right into first 231 account ignoring any of the lesser numbers. There is more - when I changed query to search for '5%' like accounts, I gained the same result - accounts less than 530 were ignored even if I typed "50" or "51". BUT - when I changed query sort order to "desc", all account became "findable".
    I got this problem in one database only which is SAP 8.8 PL10 version upgraded recently from 2007A one. I've checked with a newly created 8.8 and such problem hasn't occured.

    Hello Thomasz,
    I might be off base here, what happens when you use this??? 
    Do you get the same types of query window problem???
    Select
    acctcode,
    acctname,
    segment_0
    from OACT
    where Segment_0 like '2%'
    order by acctcode
    for browse
