Satellite L855-124 cannot change the brightness of the display after Win 8 upgraded

Hi all

I have a problem with my laptop Toshiba Satellite L855 - 124 PSKACE.
After the upgrade to Windows 8, I can't change the backlight brightness of the screen of the laptop.

There seems to be an error in the graphics driver.
When I install the AMD graphics driver of Windows 7 in compatibility, it works again, but bugs on other areas.

Anyone have any ideas?
Even after you use the upgrade wizard provided by Toshiba, it does nothing.
Also the drivers for my laptop are not updated. From 2012.

I called tech support, they told me that a pilot team is going to be fixing the issue.
That was 2 months ago.

Is there anyone from Toshiba which can help me with this please?

Thank you.

> When I install the AMD graphics driver of Windows 7 in compatibility, it works again, but bugs on other areas.

So, it looks like a problem of graphics card driver.
Have you tried the win 8 64 bit * v8.982.7 * driver Toshiba UE page graphics card?

  • Satellite L855 - 13G - cannot use the Webclaim service

    Hello

    I bought a Toshiba Satellite L855 - 13G (PSKACE-04Y00CFR) in France last year, but this computer is already leading me in trouble!

    The graphics makes noise, one of the USB port does not work, and now, without any change of software, the computer shuts off after displaying a blue screen with "KERNEL_DATA_INPAGE_ERROR".
    This blue screen just randomly (say about two or three times a day).

    I would send this computer for repair, but now I find something very weird: Toshiba has done everything possible to hide L855 - 13G!

    All first of all without result on the Web site:
    https://www.Google.co.UK/#q=%22l855+13g%22+site:Toshiba.com

    Second, the model is not listed in the support Center:
    https://www.Toshiba.fr/innovation/generic/SUPPORT_PORTAL/
    When I enter the serial number: no result. Also using the fields ' or is your product "model is not listed.

    Third, and better, I can't access the service of warranty claim for a Toshiba product for this computer: when I'm on https://weblord.toshiba-tro.de/Webclaim/ and I fill the serial number, the computer is identified (Alleluia), I have a green check mark for the status of the guarantee and "your product is still in warranty period."

    But then, I can't click next and mention "product not available: Unfortunately your product is currently not available" appears instead.

    So... apparently Toshiba is is best to forget about the Toshiba Satellite L855 - 13 G, but for unlucky enough to have people buy a what are the next steps?

    I would like to be contacted by someone from Toshiba to get an answer or a proposal to change my computer or at least fix it!

    Many thanks in advance,
    Best regards.

    > I would like to be contacted by someone from Toshiba to get an answer or a proposal to change my computer or at least fix it!

    First of all, I want to provide you with information on this community.
    This is a user to user community where you meant fans of Toshiba. You won't find any Toshiba here people

    Now some details about the fix for laptop:
    In case your laptop computer s hardware began to malfunction, you can contact the maintainer authorized Toshiba in your country in order to fix hardware problems.
    Here on this page of Toshiba ASP you can find all available worldwide FSA:
    http://www.Toshiba.EU/innovation/generic/ASP_SUPPORT/

    Last but not least, he should know that the warranty only covers hardware problems.
    If in case the laptop does not work due to some software problem, the warranty would not cover the cost. This is why I would recommend you to retrieve the computer laptop back to factory BEFORE you contact the ASP.

    I hope this info helps a bit.

  • Satellite L755D-11W: cannot change the graphics chip in the game settings

    Hello

    On my laptop Satellite-L755D-11W, in some games and applications does not change the graphics chip. Otherwise said, at the time to choose the right game, I want to put a high-performance and change AMD Radeon HD 6400 M-> AMD Radeon (TM) HD 6520 G, click Save... but the settings are not saved and the AMD Radeon (TM) HD 6520 G is not selected for the match (())

    This happens not always, but often in the games and 3DMark2011.
    Drivers for video cards are the last who are on the Toshiba Support site.
    Official website of the AMD driver only is not supported (())

    Please help with this problem!

    Hello

    L755D-11W uses the AMD Radeon HD 6470 M graphics chip.
    So what GPU belongs to the Radeon HD64xx series and I don t think you could choose a series superior GPU (AMD Radeon (TM) HD 6520 G) in the properties of the game if the GPU is not supported.

  • Satellite R630-141 - cannot change the boot order

    I have a Toshiba R630-141 and I'm changing the boot order in the Bios, but the Bios does not allow me to choose my cd drive or a USB drive as the startup disk.

    I've updated the Bios today to the latest version, thinking that I need the latest version but still the Bios allows me to change the order.

    The problem is the screen flashes only when I'm in the form of change of boot order. When I select the upper and down arrows to select an option in the box just blinks and does not allow me to select any option.

    I tried the tab key, the number keys basically all of the keys that I on the keyboard, and still, I can't select usb or cd drive so I have to quit and restart.

    Any ideas would be appreciated.

    Hi scarpentier,

    You can change the boot order in the BIOS and booting from another boot device? Go into the BIOS and change the boot order. Enter a startup disk (e. g. Toshiba recovery disc), save & exit the BIOS Setup. The computer will restart and should boot from the CD.

  • Cannot change the Contacts after having migrated to Tungsten E2

    Hello

    I recently migrated my old Tungsten e - whose battery life started shit after years of use - to a new Tungsten E2.  To my horror, I found that even if I change the contacts on the Palm Desktop, when I edit existing on my Tungsten E2 device contacts, after that I have make changes & press 'fact - fact-[complete]', the changes I made are not actually saved.  Indeed, I'm unable to change existing contacts on my device.

    After some tests, I found that this problem is true only for my legacy contacts records that have been migrated from my old Palm.  If I create a new contact, the new Tungsten E2 or via the desktop record, I can edit it and make changes without problem on the handheld.  (Note that I can edit notes, back and some calendar entries without problem).

    I have the Palm OS v. 5.4.7 on the device and the Palm Desktop 4.1.4 on the XP PC.

    I suspect that the problem is related to the fact that last spring I upgraded my PC at home and a MacBook Pro for a period months I HotSync my Palm Tungsten E to work on my XP machine and then also home for my new MacBook Pro (I like the idea of two sets of backups).  It worked well in time.  But now that I've migrated to the Tungsten E, I wonder if some not-so - wonderful things were made to my contact records of sync for two different platforms at home and work.  Note for both I used the desktop software Palm native to HotSync (a pleasure on XP, less on the Mac).

    Yesterday, I spent two hours with Palm time support staff via chat online and also on the phone.  After several soft resets, resets hard to export my contact data and then - import, blah and blah, their conclusion was, "sorry, your data is corrupted, we cannot help you.'  Hmmm.

    I am interested in anyone's thoughts on how to solve this riddle.  My bet is it's fixable with the right know-how.

    Thank you.

  • Satellite L555-S7008 - cannot install the display driver Windows 7

    Hi guys

    I'm confused now
    I have a Satellite L555-S7008, I installed a Windows 7 ultimate edition, but unfortunately the display driver did not work. Now I have pain in my eys because of the resolution. What should I do to make it work?

    Hardware found "Mobile Intel (r) 4 Series Express Chipset Family", but it does not support this type of material

    (2) what driver should I I installed to the PCI network communication controller?

    Hi ROCO_1,

    I had a similar problem with the display driver I t could not install it. I put t know why it happened, but the solution is that you need to install the display driver through the Device Manager and not from the configuration file

    So go into Device Manager and right-click on the graphics card and select put to update driver. Do not choose the Advanced installation where you can choose the driver directory yourself. Select the files that you have unpacked the file downloaded and that s all.

    About the communication network PCI controller, it could be both: WLAN or LAN card. So, make sure that the two drivers are installed.

  • Satellite A100-590 - cannot install the display driver for Win7

    I installed Win7 on my Satellite A100-590 (PSAA9E-03Z00QGR) today. Everything works fine except for the display drivers.
    I downloaded the drivers win7/32 bit here: [here | http://at.computers.toshiba-europe.com/innovation/jsp/SUPPORTSECTION/discontinuedProductPage.do?service=AT&BV_UseBVCook = Yes & PRODUCT_ID = 115970 ie] but when I try to install, extract the files and then nothing happens.

    Does anyone else have this problem or even better a solution? all other drivers will work on this laptop?

    Edit: the graphics card is an ATI Mobility Radeon X 1600

    Extract the files in a new folder created. Open it and use setup.exe.
    What happens when you start it manually using setup.exe?

    Alternatively, you can try to start the installation in the Bin folder.

  • Cannot change the settings after the take snapshot in VM

    Hello forum, I need to increase a disc size and the number of virtual processors on couple of virtual machines, the last week I have instant tool of these virtual machines. Today, when I try to change the settings, I see that the options are grayed out. Why is it so? This is a limitation of vmware. Do I have to delete the snapshots before making changes? Which will remove the ability to roll back changes if necessary. I'm under Windows 2008 R2 virtual machines.

    Virtual disks can only increase if they have no active snapshots. The snapshot files contains modified data blocks that correspond to their parent records, and this mapping I lost if you have increased a virtual disk with snapshots.

  • Satellite A100-294: cannot change the built-in RAM module?

    The integrated RAM (512 MB) of my Satellite module problems (based on memtest86) and the machine was freezing all the time. It is under warranty, so I got to the store I bought.

    They told me that they send the machine to Toshiba AC because it will probably be a new mainboard to correct the problem, since the DIMM is permanently attached to the Board and cannot be changed as all the regular module DIMM.

    Is this true? Is the 512 MB of RAM the machine is supplied with, physically inseparable from the motherboard?

    Hello

    As much as I know doses Satellite A100-294 does not in charge of the internal memory!
    The unit simply uses the memory DDR2-533 modules that are removable.
    The memory location is placed at the bottom of the unit and it s easy to reach.

    But maybe the head technicians would like to take a look at this motherboard and therefore the ASP had to send this book to the Toshiba headquarters

  • Can satellite L655-14F - I change the display driver?

    all I want to know if I can 'Upgrade graphics card in my laptop.

    Satellite L655-14F...... Hotel details

    "Graphics card".

    type: ATI Mobility Radeon HD 5650 related HyperMemory technology
    amount of memory: 1 024 MB dedicated VRAM (total available graphics memory using HyperMemory technology can be up to 2 267 MB with 3 GB and 32-bit operating system and 8 GB memory 4 083 MB with a 64 - bit OS system memory or system)
    "type of memory: DDR3 video RAM (resp. RAM video and system memory combined)"

    We are talking on cell phones and the No. Laptops have a very specific design and hardware upgrade is limited. Generally updated graphics card is not supported by Toshiba, so there is no sense of thinking about it.

    Cooling system's biggest problem with laptops. Each laptop has the system of cooling optimized for certain physical infrastructure. Build in the cooling system should cool the hardware components and protect them from overheating and damage.

    I will now use the same word as badhat: theoretically if you upgrade graphics card, you will have more powerful piece of hardware that produces more heat than the original. More heat means more likely to damage the material.

    You can upgrade level RAM or HARD drive, but everything else is meaningless. That s in my opinion.

    Why don't l t buy you more powerful laptop? Something like Satellite A660, P750 or Qosmio?

    Hello!

    Have you tried to install the driver to display on the Toshiba site? You can find it here:
    http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

    Before you try to install a new display driver, you must remove any old version in Add/Remove programs. Then, restart the laptop and use CCleaner to clean the system. Restart again and then install the new version.

    You have the same problem with the factory settings? In the worst case, you must reinstall Windows using Toshiba recovery disc.

  • Satellite A100 (PSAA9E) - Cannot install the display driver for Windows 7

    I have a problem with installing official Toshiba Windows 7 x 32 ATI x 1600 driver.

    After unpacking it should run install.exe, I think, but it's not; nothing happens. Go on the Setup.exe with installation manual, then I see no Catalyst Control Center & Display Driver from the list, just the catalyst install Manager & vcredist. After installing these components (CCC & DD) are not present.

    Any ideas?

    P.S. Same problem with the official driver of Toshiba Vista32 ATI x 1600.

    Hi mate,

    You have already installed other drivers for the laptop? I mean the chipset driver, this driver must be installed first.
    And are you sure that you have ATI display driver? Some Satellite A100 models were shipped with the nVidia graphics card, AFAIK.

    Moreover, what happens if you install driver manual in device via advanced installation manager?
