Satellite L50-A-111: dimming does not work properly after Win 8.1 upgrade

Hello

I have a problem with my laptop computer truebright LED monitor.
Brightness works correctly, but the brightness variation is not.

I should be able to choose from a range of 0 to 100% in both, but in gradation brightness that I can not only get up to 10% even though it says its 100%
because when I level down it says 8,6,5,3,1 level and 0 when I get home eco and when I max he says 10% for 1 second, then 100%.

Oh and something important, change the brightness variation has no effect at all, I think it's just stuck at 10%.

But I know clearly that it is 10%.
I tried everything so far, restore archive and the registry.
It wasn't even until I restored the registry. I also tried advanced options that once solved this problem for me, tried everything, expect to reinstall the operating system.

I installed windows 8.1 Windows store recently I don't know if its related.
All my drivers are up to date.
Happened yesterday after Batman Arkham City GOTY installing and disabling the Anti Virus, Firewall, etc...

I don't know what else to try, im really frustrated, I can't handle this without the gradation of light at its maximum. My only concern is to reinstall the operating system did not solve my problems.

Please give me some info on how to solve this problem, I'll try the registry if someone can help out me.
Thank you in advance.

My best regards,

Sir. º Micael liberal

Hello

To be honest I m a bit confused.

You said that you have upgraded to Win 8.1
After these updates, you must update all the Toshiba drivers as mentioned on the 8.1 win Toshiba upgrade page.
On the page of the Toshiba UE driver you can find the installation instructions that will show you how to install / update all drivers.

This is very important!

  • Satellite P25-S520 - DVD player does not work properly

    Difficulty of DVD player or buy the external drive

    My DVD player does not work properly, in fact it can never work properly. Recently, I tried to back up my PC on a DVD using Norton 360. Norton did not recognize that the DVD was present. Then I tried to write a text file on a DVD and was a failure. DVD + R and DVD-R media were found to be (Maxwell 16 X).

    I could have probably lived with this however, I received a copy of Dragon NaturallySpeaking version 10 on a CD and my Toshiba would not recognize it. I tried the CD in my laptop nearby and it was recognized.

    An attempt to update the driver has also fails.

    I was able to copy a CD of music last night so that at least works properly.

    Does anyone know how can I fix? The important part is to be able to load my new program.

    Research on some forums I found that other people have had problems with the Pioneer drive. If the drive can't be fixed, I'm not adverse to buying an external DVD drive. Unfortunately, where I live there is no brick and mortar stores selling external drives and I prefer to avoid the hassle of getting a drive online and discovering that it does not work with my Toshiba. Can someone suggest an external USB drive that will read and write CD and DVD and is certain to be compatible with my Toshiba?

    Thanks for any help,

    Any external USB CD/DVD drive will be compatible with your laptop.

    However, you won't be able to boot from CD (run recovery for example) If you are using an external drive.

    So, your best option would be to replace the internal drive with a Toshiba drive designed for the laptop. Call an ASP and request a quote.

  • Satellite L50-B-211 - Touchpad does not work

    Hi I have a question

    We just bought a Satellite L50-B-211, but the touchpad is not working properly.
    Move the pointer autour is no problem, but the buttons do not work.

    Using the buttons does nothing, left or right clicking has no effect?
    If I want to get the properties of a file right-clicking does not work?
    (two fingers press work)

    The hardware is correctly installed, there is no problem in the configuration of the device.

    Do I have to return the device (before installing our software / config the device to our needs)
    or is this a software bug?

    According to specification for laptop, your laptop was supplied with Win8.1 pre-installed so that all the necessary drivers are installed and all hardware should work fine.

    Try please check all the touchpad settings and check if changing the settings has positive effect.
    What you can try to do is to reinstall the original recovery image and test once more with the factory settings. If the result will be the same, I recommend you to contact your dealer as soon as possible and explain the situation. Ask if you can get the new machine.

    Hi all

    as the title suggests, the webcam built-in in my Toshiba Satellite P300D-110 does not work correctly. Allow me to explain.

    Whenever I try to use my camera with applications such as MSN Live Messenger, Skype or on community websites, using Firefox, Internet Explorer or Safari the app crashes.

    * How what happened? *

    You tell me. That's how it happened;
    * 1st day: I booted up my laptop and looked at my installation fresh and clean Windows vista Home premium. I tried my webcam using the webcam support software and it worked like a charm.
    * Day 2: once I start my laptop and try to start my webcam only to find out that he is no longer functions.
    To give a quick summary of the thread;

    Help of camera Assistance software provided by Toshiba, can I take pictures.
    Help of camera Assistance software provided by Toshiba, I can record the sound.
    Using camera Assistance software provided by Toshiba I can _ * NOT * _ save or preview of a video.

    Sincerely,

    a sad customer.

    Can you please describe the steps how you try to do this? I have to ask you this question because it works fine on my laptop. When the recording is finished Player opens and you can see saved the film. This is the avi format and at the top of this player, you can see the path where the film is recorded.

    Strangest thing for me, is that you can not use it with Skype. OK for MSN is not perfect, but there is absolutely no problem with Skype. Make sure the settings and it should work somehow.

  • Qosmio X 875 - ECO mode does not work immediately after Win 8 upgrade

    I used the upgrade Toshiba Upgrade Wizard to Win 8. He succeeded well uninstall the incompatible software before the upgrade and install the new Toshiba and driver versions after the upgrade.

    I activated the ECO mode, and to my surprise, it does not work as before (in Windows 7):

    * Now, it works with the brightness to level 1 *... very dark. Before, ECO mode allowed me to go up to level 4 and was always considered in Eco mode...

    If I increase the brightness, the 'eco mode is disabled' message opens immediately.

    How to contact Toshiba to inform them of this problem and the other problem I found with the new BIOS?

    BTW, I am owner of a Qosmio X 875

    Contact your Toshiba authorized service provider in your country.

    Read this:

    > It changes the brightness of the display of level 4, changes the brightness of the grey screen of level 1 (* 4),.
    _The * 4 means only on models with Windows7 installed _

    I guess that the previous configuration was only Win 7.

    8 win was made for mobile (use of the Tablet), the energy consumption of battery is also very important plant help to win 8. The consumption of the battery must be taken at the lowest level possible.
    So I guess that now help win 8 ECO medium mode and save the power max and long battery life time working at a max level.

  • computer does not work properly after the update, because the screen is black.

    Advice please! :-(

    After an update there about 2 months, my computer has never worked properly after that I turned it back. My windows start page is longer there. My screen is black. The words are only in white and fluorescent yellow...

    The only way I can go online to find Norton (is always at the bottom of the black screen) and go to help. I can get a search bar like that. Almost as if this black screen hides everything below.  Computer is 13 months old.

    My internet provider says it isn't them. Gateway said it's not my computer so idk what happened after this update.

    Any advice would be so appreciated.

    Thank you.

    Hi Patty,.

    Welcome to the Microsoft community. I would be grateful if you can answer these questions.

    1. You have installed the latest drivers for Windows 8?
    2. What is the model number for Gateway computer?

    If you get a black screen after upgrade to Windows 8, it might be due to an outdated or incompatible graphics card driver. Update to the latest version of the display driver should fix this.

    Try to remove all external devices connected to the computer and then try to start the computer and check if it works. Follow these methods and check if that helps:

    Method 1: To resolve this problem, update the Gateway website. video card driver

    Step 1: Check out these Microsoft items for additional reference:

    Download and install the drivers

    http://Windows.Microsoft.com/en-in/Windows-8/all-drivers

    Step 2: If you are not able to find drivers for Windows 8 to HP support. Try to install the graphics drivers in compatibility mode and check:

    Download your applications and devices in Windows 8.1

    http://Windows.Microsoft.com/en-in/Windows-8/get-apps-devices-working

    If the problem persists, proceed to the next method.

    Method 2: I suggest to follow the suggestions provided in this Microsoft KB article and check if this can help:

    Windows 8 starts with a blank screen after a standard or hibernation

  • Chicony webcam on Satellite Pro P200 1.3 does not work properly

    This built-in Chicony webcam is slowly driving me insane.

    Sometimes it works (not since last week though). Usually, I get a message saying it is locked by another application - or it does not exist. Now, I can not even friends view webcams.

    The cam is displayed on my screen and seems perfect, but no one can see me! When I try to view the cam of friends, I am told that it is not connected.

    Now, I checked my device manager and it is not yet installed-just disappeared! I have recommended download driver Toshiba Europe (camsoft-2007081...), uncompressed, ran it, restarted, but apparently my laptop does not detect the webcam - even if a blue light flashes!

    Please get out me of my misery... someone!

    Thank you, thank you, gratias, go raibh mile, etc., etc.

    I read that sometimes the internal TV tuner would block the internal webcam and so this error message.
    But as far as I know this laptop was not equipped the internal TV tuner, and therefore, this possibility is not relevant.

    Always is it that any application locks the webcam software. In case you would you recommend to go the msconfig and disable first the webcam services that run in the background. Then turn it back on.

    In most cases, this helps!
    By the way; I noticed this problem only with yahoo messenger and ms. Skype works ok!

    > Some keys on the keyboard on our Satellite C850 - 1 c 4 have stopped working.
    In case the USB keyboard would work correctly, the problem is related to a malfunction of the internal keyboard and the solution is simple: the defective part (in this case the internal keyboard) needs to be replaced.

    This can be done by the Toshiba authorised service provider available in your country.
