Satellite C855-1TC - brightness and volume buttons do not work

I don't know what I did, but they no longer work.

I tried to install the 'value added package' but it does not solve the problem, unless I did it wrong.
This isn't a huge problem, but I have not missed them. Help please?

I'm not very tech savvy, as well as any other thing you need from me to help?

Hello

It seems that the laptop was preinstalled with the system of 64-bit Windows 8.

Use you still win it 8?
A few months earlier, the new 8.1 Win was released by SM.
I recommend you to upgrade the win 8 to 8.1 Win exactly following the instructions step by step by Toshiba
http://www.Toshiba.EU/innovation/generic/windows8_1-message/

After upgrade from 8.1 to win, you need to update and install all Toshiba drivers earn 8.1.

After, I suppose that the function keys work ok.

    Hello

    First one comment:
    * I am updating my laptop regularly whenever I get alert through TEMPRO or Toshiba service center. *
    That s is nice, but certainly not necessary. When the system is working, do not touch or change anything. Maybe stupid sounds now, but I recommend you to remove the TEMPRO system. Believe me you don't need. I have 2 years old Satellite A300 and original BIOS. It works perfectly and I don't want to take any chances and to change what anyone. Since last month, I have the Satellite U500-1EX and will do the same. TEMPRO is already removed, and I am happy with the factory settings.

    All that you have done is OK, but at least you can try to reinstall entire OS now using HDD recovery option (F8 at startup) to see if everything works well again. Sorry, but if this will not help, I think that you need the BIOS downgrade to the old version.

  • Satellite L650-19W - FN and ReelTime button do not work

    Im having problems with the function key. Since he can't work easily does not alter changes such as the brightness of the screen, screen etc. Other Toshiba software do not either as ReelTime.

    I think that I may have to reinstall the Toshiba Utilities, but since it is pre-installed im do not know how to do this or fix the problem.

    Any help appreciated.

    It is for the Satellite L650-19W

    Hey Buddy,

    The FN keys are associated with Toshiba Value added Package, and Flash Cards Support utility. These two tools can be downloaded from the official website of Toshiba:
    http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

    TOSHIBA ReelTime is also available on the same page, so you can reinstall all these tools they don t work anymore. After reinstalling, everything should be working again :)

  • Satellite U500 - the volume buttons do not work

    Hello

    I just bought a Toshiba Satellite U500 two days ago and already problems :(

    It has a control buttons sensitive contact, which includes the eco, the media buttons and the volume control utility (+ and -)
    The volume buttons do not work, and sometimes the computer crashes to their contact. Once I touch the-, he begins to turn volume down until it reaches zero, and even if I turn it up using windows, back to zero (as if the button is still depressed). The + does not work.

    Help, please. Is it possible to re-install the drivers?
    The only solution I found is to disable them using HWSetup...

    Great news. Thanks for the comments!

    If you come from the United States, I'm afraid, you're on the wrong place. Try to post the same thing on http://community.compuserve.com/n/pfx/forum.aspx?webtag=ws-laptop&redirCnt=1 it's US forum.

    Here are mostly from Europe and Toshiba Europe has nothing to do with Toshiba WE. The company, but may be different marketing strategy and support.
    Maybe you'll find people with the same opinion.

    > 1200 for a machine that cannot dim the lcd...!
    I take you seriously with your opinion, but after reading this, I think that this comment has nothing to do with reality. Recovery of installation image and you'll have the complete functionality for laptop. You have the stick of Windows Vista on your laptop?

  • Satellite A660 - touch pad / stop and other buttons do not work

    Dear people on this forum,

    Recently, about 3 weeks ago, I turned on my computer and I cleaned out the dust because it was overheating.

    about 2 weeks before, I noticed that my touchpad is not working and the buttons at the top of the page do not work, there is no light (multimedia audio buttons wireless) I can't activate/deactivate or either, I don't know how. I don't know if the problem because I cleaned my laptop and has not logged a few threads back but I included this detail because I do not use these buttons if I haven't noticed if they were on. but he said: 2 days ago, I don't know how my wireless exploded Ant when I press fn + f8 (wireless) wireless communication switch is turned off, which is one of the buttons is not working (upstairs next to / switch even with my touch pad)

    I tried the following:

    Windows Update
    turn off the computer, remove all cables and battery and wait for about 30 minutes. Then then hold down the button for 30 seconds
    Reinstall the support flash cards, hw Setup utility / value pack
    and finally a Toshiba out of the recovery of the box using the recovery of 2 cd product

    I don't know what to do next. It's either:

    try something else
    or is there a wire is connected both touchpad and the buttons at the top and I have to open my laptop and connect them.

    Please answer as to my next step to get my wireless.

    Please don t get me wrong, but I don t know how to help you now. Disassembly of the laptop is to only authorized persons and if you do it on your own there is always a risk that something may be hurt or may be damaged.

    OK, I must also say that I also removed my machine too but I got lucky and everything is OK as before.
    I put t know how A660 looks inside, but the principle is still the same and I can't imagine you have whatever it is damaged.
    You know very well that we cannot say much about your problem. What you need to do now is the final test of functionality and install original recovery image that you got with your laptop. Test the functionality with the factory settings. If the problem is still there, I m afraid you must open for new laptop and check if everything is connected correctly.

    Last option is to contact the service and ask for help.

  • Satellite U500 - 1 8 - eco and touchpad button do not work

    I had to update my Windows 7 Profesional version and now I have some problems:

    1. I installed eco utility but when I press the single button of co control nothing happends
    2 start/stop pad touch button does not work (not as important)
    3. when I press the fn button context menu? (the bar at the top of the screen with shortcut explanation)

    I looked on the toshiba site, but can not find good files someone help me?

    Thanks in advance

    Hello

    In my opinion, you must reinstall Toshiba Value added Package and the Eco utility. All utilities, you can get on the Toshiba site:
    http://EU.computers.Toshiba-Europe.com > support & downloads > download drivers

    So I agree with the user above the reinstallation of this tools, everything should work properly again.

  • Re: Satellite L655 - the Touchpad on/off button does not work

    This morning, I noticed that the power button of the touchpad of my Satellite does not, although the Fn + F9 key combination works by enabling and disabling my touchpad.

    It was working well until what I slept last night when I woke up, my laptop has rebooted due to updates of Windows during the night. I don't read anything since I have been using a wireless mouse. Then reach work and check if I can activate my touchpad (Windows has loaded and connected), the display screen that shows if the touchpad is active or not does not appear and my touchpad, power button does not work.

    Any help is greatly appreciated.

    Thank you.

    Is this problem only you?
    I mean it's not so important, and I would not reinstall or change anything because of this.
    Until you can use the FN + F9 key combination I put t think it's a serious problem.

    What do you think of this?

  • Satellite A300 - 1GN PASGCE - LED light button does not work with Win 7

    I improve my laptop for windows 7 everything works fine but the touchpad multimedia light led power button does not work.
    Play, stop, next work earlier but not the light / off does not work.

    No idea why?

    Hello

    Maybe it's a question of s a Win 7.
    I mean that the software is not intended for Win 7 but only for Vista.

    But you should check if you can reconfigure this button again.
    In Toshiba Assist-> optimize, you can find the Support of Toshiba Button tool.
    This tool can be used for the new configuration of the control buttons.

    First click on the button that you want to reconfigure and target path you can then choose the path to the exe file that must be executed by pressing this button.

    As far as I know that the exe files are placed in the program files/Toshiba/TSB folder.

    You will find different applications and one of these applications control the light on/off.
