  • Windows 8 Pro Upgrade Problems (Switchable Graphics, Screen Brightness Adjustment, etc.)

    Hi guys! I hope you can help me with this.
    My laptop is a Lenovo U400 bought last April. I upgraded it yesterday to Windows 8 Pro.
    The Upgrade Assistant detected incompatibilities on the following softwares (I'll be mentioning only those I had problems with after the update.)
    -AMD Catalyst Install Manager
    -Catalyst Control Center
    -Lenovo Energy Management
    -Cypress Trackpad
    After the update, the following problems occurred
    -Windows kept prompting me about the incompatibility of Catalyst Control Center and Lenovo Energy Management
    -When I check the Device Manager -->Display Adapters, My AMD Radeon HD 6470M was changed to HD 7400M and has an exclamation point on it indicating a problem. When check Properties it says, "Windows has stopped this device because it has reported problems. (Code 43)"
    -I can't manage switchable graphics because the AMD Radeon driver has been stopped by the OS and Catalyst Control Center doesn't work. It says, "Catalyst Control Center cannot be started. There are currently no settings that can be configured using Catalyst Control Center."
    -My touchpad works but does not support multitouch functions.
    -Screen brightness adjustment stopped working both on hotkeys and Power Options.
    I tried the following actions to fix the problems:
    -Downloaded the new softwares from Lenovo Support but the Catalyst Control Center and Cypress Trackpad still doesn't work. I also tried installing driver software from the AMD site but it still didn't work. [FAILED]
    -I tried to use the Cypress Trackpad software for U300s/e and it fixed the problem with the touchpad [FIXED]
    -Installed the Energy Management software for Windows 8 but when I click the 'Optimized Battery Health' button, it keeps reverting back to 'Maximum Battery Life'. [PARTIALLY FIXED]
    -Resorted to 3rd party software to fix the Switchable Graphics (Catalyst 12.11 Beta from leshcatlabs.net) and it fixed the switchable graphics problem as well as the Catalyst Control Center problem. This is temporary until a working solution or update is available. [TEMPORARILY FIXED]
    -All actions trying to fix the Screen brightness adjustment didn't work. [FAILED]
    Please do help me on this. Thanks in advance!!!

    Yes I own U400 too and I'm using it now. To many forums been read, can't remember which one. Basically, u have to clean AMD and Intel drivers that come along with Win 8. Why? Because the Win8 driver database will lead the device ID "DEV_6760" (if you looking at display adapter device properties) to HD 7400 series instead of HD 6470M, again why? At the bigining only the HD 7400 series already "certified" by Microsoft, while the 6470M out of somewhere. Current CCC (or else) + 6470 drivers, contain also driver for 7400 series in same packages (at least until now, hopefully near future they will release an update). So you can gues where the windows will lead to? Yes 7400 series (certified one). This will explain also why the Energy Management didn't work to= "missing identifier" or we can say "hardware not match".
    You have to find a "fix" driver which contain only HD 6470M and install it manually trhu "Have Disk" option, after you claan all AMD and Intel driver. If you success, then install the CCC from Lenovo Support and from ATI ( I use 12.11 Beta8 Net4 CCC - this is a must), but remember to unchek the AMD Display driver when you install both CCC, and leave the rest checked including Intel Component. Then you can download install anything you want =).
    Leschat's driver did't work on my and "harm" the system. Believe it or not, I found the AMD 6470M standalone driver on HP website. They call it "SoftPack", which actually contain CCC software.
    It's quite tricky thing, that's why not everyone willing to try. But I think it's worth to try, as the risk is not too deep, just backup anything befor you do it. Cheer

  • Screen brightness adjustment broken

    Since the latest updates to the kernel/udev/kmod, I can no longer control my screen brightness via KDE. This used to work perfectly. Neither the Fn-F6/F7 key combination, nor the "Screen Brightness" slider on the KDE power management tool changes the brightness.
    Is this a known issue? If so, is there a workaround...?
    I use a Toshiba A500 laptop. Like I mentioned, this worked last week, before I ran pacman -Syu :-(
    The real problem is that it seems stuck at the highest brightness - this is draining my battery within 20 minutes.
    Is there another way to adjust the screen brightness?

  • Satellite A100 (PSAA9): Win7 + screen brightness adjustment issue

    Hi
    I have installed Windows 7 64-bit on my toshiba A100 (psaa9) machine, and i cannot modify screen brightness anymore.
    It is maximum brightness always. Fn key does not work, and neigther i can modify the brightness manually through nvidia control panel. nvidia driver is 7.15.11.7967, installed automatically with windows.
    In a similar thread http://forums.computers.toshiba-europe.com/forums/thread.jspa?messageID=182780

    how can i fix my problem?
    thanks

    hi all,
    thank you for reply!!!
    ok, i tried to install VAP and Flash Card Utility for Satellite L500. first, installing Flash Card Utility i got invalid serial number error. i've read in forum that it might be due to inappropriate driver for my version on laptop or if i did not install VAP first. so, second, i tried to installed VAP, but i get value "Setup tvap error 0x8146045B" :(
    according my display driver: it was nVidia driver automatically installed with win7. in fact there is no display driver for win7 64bit version on toshiba website... i guess i have more problems with display, as my secondary display blinks every time some system event like driver/program installation or usb device plugging-in or -out happens.

    Hi.
    I failed to configure xorg.conf to get "static" dual head configuration, but I managed to do this with xrandr
    2 tricks i had to do:
    1. define sufficiently large "Virtual" size in "Display" subsection in "Screen" Section of your xorg.conf
    2. xrandr -q allowed me to use 1024x768 maximum  resolution, but I found in google setup for 1280x1024 and added it with "newmode" and "addmode" options in randr...
    you can find more info at http://www.intellinuxgraphics.org/dualhead.html, and in xrandr manpage.
    I hope it will help...

  • ALC 268 Intel HD audio realtek chip Toshiba a205-s4577

    I am wondering if anyone was able to get sound out of the alc 268 realtek chip using the 2.6.22 kernel.
    I recently installed arch thinking somone might upload a custom kernel which works for this laptop model.
    I was earlier using gutsy and have a bug report submitted there.
    https://bugs.launchpad.net/ubuntu/+sour … bug/116326
    Please help if someone knows what could be done

    Hey, thx a lot dude. That helped a bunch.
    Now I know it's the audio. The soundtrack keeps getting stuck like a broken CD, it will repeat some part then jump ahead. It's definitely an audio issue. Any ideas?
    I tried turning off all of my sound drivers in the Device Manager. It works much better but I still get some of that weird lagg. (I'm playing Diablo 3). There will be no lag at all for 10 secs then I get like a spike where it just completely freezes for 1 second, then it moves on again.
    When I look at my task manager the computer isn't running anywhere near at 100 %. I'm starting to think it's a hardware issue. The lag follows the same pattern no matter if my video settings are at high/low and will occur even if I'm standing perfectly still. At this point my processor worked at 18 % of max capacity.

  • F5 and F6 keys (MacBook Pro) do not adjust screen brightness after upgrade to OS X Lion

    Hi All,
    since "upgrading" my MacBook Pro from Snow Leopard to Lion, the F5 and F6 keys for adjusting the monitor brightness do not work anymore! No matter how I set the settings for the monitor, the keys do not work.
    Sometimes, the MacBook now just uses a low brightness and the only way to modify this is to open the system settings and change it there.
    Does anyone know how to fix this so that it works properly (like in Snow Leopard) ?
    Thanks,
    Kristian.

    The screen brightness adjustment is F1 and F2.
    You can also adjust in System Preferences > Displays.

  • Cannot adjust screen brightness in Windows 8.1 on my G50-45

    Hello there,
    I just bought my new lenovo and instantly upgrade the system software into Windows 8.1.
    Everthing looks fine instead of the screen brightness adjustment, i've downloaded the latest graphic drivers but nothing happened.
    The display adaptor section into device manager keeps showing up that the driver is Microsoft Basic Display Adaptor rather than AMD radeon R2.
    Thanks in advance guys.

    hi kostas-mi , ecountered that issue a month ago and was able to resolved it
    things you can try:
    1- you can roll back the driver back to its stock state, if this doesnt work ,  
    2- install latest driver of your graphic card
    3- This step will fix the problem:
    - go to registery by regedit and change the value to 0xf048
    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
    "FeatureTestControl"=dword:0000f048
     OR
    [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001]
    "FeatureTestControl"=dword:0000f048

  • New W520 cant adjust screen brightness!

    Hello,
    I am new to the forum and new to lenovo.
    Just started setting up my brand new w520 and the Fn+Home/End keys dont work to control display brightness.
    Any w520 owners having this problem as well?
    edit note:- split from initial thread. change subject to reflect content.

    @johnt7225,
    Appreciate if you could try running TVSU and Windows Update to ensure all the drivers are installed.
    Also is X-Rite a default software which comes with the W520? (I am unable to confirm this as I do not have a W520 to test on) ...
    If X-Rite is the one acting up and causing the screen brightness adjustment to not work, I would need to escalate this to engineering.
    Thanks Johnt725.

  • Tab & Backspace Keys are changing my screen brightness how do I change this?

    I have an iMac that I have had for a couple of years. Suddenly the backspace key and tab key are adjusting the screen brightness and I can't seem to change this, any ideas why this has happened and how I just get screen brightness adjusted by using F1 & F2 keys? I have tried kedyboard shortcuts from system preferences but this doesn't seem to make any difference. Any help really appreciated

    As far as I know the language of the two stores on the iPad (iTunes and the App Store) can't be changed - they should be in the language of the country where your account is based (if they aren't correct then try logging out of your account by tapping on your id in Settings > Store and then log back in).

  • Satelitte L500-1ZP: Screen brightness reversed on F6/F7 keys and on sliders

    On my satelitte L500-1ZP the screen brightness is reversed!!
    So 100% brightness is fully dimmed and 0% brightnes is fully bright!!!
    In "satelitte terms": level1 is full brightness and level8 is fully dimmed.
    Also in the windows power options screen: 0% is full brightness and 100% is dimmed!!!
    [PC Information]
    Model Name Satellite L500
    Part Number PSLS9E-01X01CDU
    OS Version Microsoft Windows 7 Home Premium 6.1.7600
    BIOS Version 1.50
    CPU Intel(R) Core(TM) i3 CPU M 330 @ 2.13GHz

    Same issue for me, But I resolved it. (I have had the L500 for 24 hours now, speakers are very poor)
    Before I changed to win7 64bit, 32bit screen brightness adjustment was ok.
    After I went to win7 64bit the controls were reversed.
    Before I installed 64bit I changed the boot speed from normal to fast. By changing it back to normal the problem reversed itself and now the controls work as expected.
    *In the BIOS menu, under "Advanced" | "Boot Speed" select "Normal"*
    *Worked for me*
    I found that to access the bios settings on boot I had to hold down the F2 key continuously while booting. (I had been tapping and it didn't work)
    I hope this helps someone.

  • Adjust Screen Brightness Satellite Pro 4200

    Hello,
    i heard from a combination of keys which makes adjusting the screen brightness possible.
    Is that true and what is the key-combination?
    Yours sincerely
    Riedlz

    Hello
    Nicky is absolutely right but as far as I know all Toshiba notebooks have the same keyboard and all have the same key combination for brightness changing. Your Satellite Pro is pretty old and at this time maybe it was a little different.
    Like Nicky already said check the Users manuals or you can download one if you need it.
    You can find it under http://209.167.114.38/support/Download/ln_byModel.htm

  • Can't adjust screen brightness.

    On my Tecra R840-S830, I recently reinstalled Windows 7 64 bit and I thought I installed the drivers I needed. My flashcard functions are working perfectly except that FN-F6 and FN-F7 will not adjust the screen brightness. I can also find no other way to adjust the brightness-It doesn't appear in power options or display settings. Any ideas? Am I missing a specific driver?

    Tecra R840-S830
    Maybe this one?

    Instead of struggling to get the install order correct, you should restore the hard disk to its original out-of-the-box contents using Toshiba recovery media.
