Equium U400 touchpad not working not

Laptop repair of my daughter: screen dead, volume control wrote letters to the screen when you use and the touchpad no longer works.

Replace the screen and the palmrest which included the touchpad, but still can not touchpad to work.
any suggestions?

Now, the screen is good, but no idea what to do with control of volume.

Any help appreciated.

> Screen is now good, but no idea what to do with control of volume.

I had a similar problem in my case it was related to dirty sensor.
I could clean it with a jet of compressed air perhaps it was little dust between the volume wheel and the sensor that knows to clean it worked.

On the touchpad:
Well, I put t know what might cause this are sure you that it is not disabled by Fn + F9 key combination? Check the BIOS settings not sure if there is an option for touchpad but many BIOS also contains the power button for touchpad
Otherwise, it might be possible that you have made some mistakes, while replacement of this part is all the cables connected properly?

  • Equium A300D touchpad not working not

    Hello

    I am a novice so please bear with me. I use an Equium A300D with Vista Home OS. I lost any use of the touchpad. (synaptics pointing device)

    I tried the key F9, uninstalled and reinstalled the driver and even tried the system restore, all to nothing does not. I have the touchpad icon on my taskbar. The backlight on the touchpad is more on. I looked in properties, and it shows as working properly without conflicts.

    One thing I noticed, is that previously, when I pressed the Fn key at the bottom left of the keyboard, the function keys are displayed on the screen. It also stopped.

    Can anyone offer advice?

    Thanks in advance.

    Yasmine :)

    Hello

    The touchpad needs two different drivers; one of Synaptics and Alps Electric 1.
    In your case, I recommend you to uninstall the two drivers. Just, delete it from the system.
    Then restart the laptop, clean the OS using a CCLeaner (free tool) and install the two drivers again!

    FN + F9 key will not work if you install t the VAP (value added package).

    Note: All these drivers can be downloaded from the Toshiba European player page and please choose the correct drivers because there are different models of Equium A300D!

  • Satellite U400: touchpad stopped working after Vista update

    Hello

    My Touchpad U400 cannot work after the upgrade, (under the Vsita system).
    I tried so many ways to solve, but still does not
    Did someone get hurt it?

    I tried to get into the BIOS to enable
    And also tried to download my touchpad driver (but I can find it)
    BTW, Fn + F9 does not work as well

    Please help me solve this problem

    Thank you very much

    > And also tried to download my touchpad driver (but I can find it)

    The touchpad driver is placed on the page of the European driver Toshiba
    http://EU.computers.Toshiba-Europe.com-> support download &-> download drivers

    Here, one must choose the right laptop model (see the bottom of the unit model number)
    Then choose the operating system and the touchpad driver should appear.

    PS: there are two touchpad drivers listed on the page; Synaptics and Alps Electric
    Both must be installed!

  • Equium U400 - Bios does not blink

    Greetings,

    I downloaded the bios update tool to update my bios from 3.1 to 4.7

    No idea how I can Flash the bios?

    Equium U400 is not supported by Win, so I don t think you could improve the BIOS to win 8.

    As much as I know BIOS update requires some essential Toshiba software that must be installed.
    For example, the value of Toshiba additional package must be installed in order to start the update of the BIOS.
    I think you have goo channes update of the BIOS of the laptop running with factory settings. I mean using the system preinstalled by Toshiba.

    But why you want to update the BIOS?
    BIOS should be updated as a last possibility to solve the problems of the laptop.

  • Touchpad not working not not on Satellite U400

    The touchpad on my U400 has stopped working.

    I tried to have him re - install at least twice by first selecting the uninstall option, where he asks a re-boot to complete uninstallation.
    After re-booting, it actually detects it and installs the driver, and just at that time the touchpad works again.

    But, he asks an another re-boot to complete the installation, after which it does not yet work.

    This could be a hardware problem? What else can I try if it's not?

    If it helps, I used two old mouse wireless with it, but them deleted during uninstall.
    I had already traded one, and I don't think that the other laptop has had this particular problem.

    Thank you!

    So I guess that you have solved your problem, and now you know how the touchpad and software work.

  • MIC not working not not on Equium U400

    I have a laptop Equium U400 and I was never able to get the microphone working properly. I'm running Vista 32 bit that was installed initially.

    The problem is that when you try to use Skype and using the call of the laboratory, the microphone does not pick up anything and Skype says it is very quiet.

    Then, I went to the microphone settings in Vista and put the volume to 100% and boost to + 20, but once more quiet, but if crank you the volume up you can hear the slightest noise. Crank the gain up to + 40 and you get all kinds of noise. I checked Skype volume settings and set it to 100% but no joy.

    I tried to reinstall the drivers for the webcam and sound using the drivers on the toshiba site, but nothing has changed.

    I wonder if anyone else has had problems or if anyone knows what is likely to be wrong, or my microphone might be broken?

    Hello

    The internal mic belongs to the internal webcam.
    The microphone settings can be changes in the software of the webcam.

    It's why start the camera wizard got to settings-> Audio tab and set the audio volume to max.

    See you soon

  • HP Pavilion - 15-ab045sa: a few gestures of precision Touchpad not working not

    Hello

    I'm new to the forum, so I hope I posted in the right place.

    My product: HP Pavilion Notebook - 15-ab045sa (ENERGY STAR)

    I have all the gestures of touchpad usual work (three stroke of finger etc).  However, the recent to THE introduced a new gesture to switch virtual desktops. I was really looking forward to this update, but this gesture does not work! I tried to reinstall the update with erase everything and it still does not work!

    I don't understand why it does not work as I have a touchpad of accuracy and all other gestures of work except this new! Also even if some gestures of work (for example three finger swipe), I don't think that win 10 recognizes the touchpad of precision like under settings of the mouse and Trackpad, what it does not say that I have a touchpad of precision and so does me no options to change what are the gestures, as it should.

    I have the Synaptics TouchPad of SMBus 19.2.11.38 driver (21/07/2016).

    Would really appreciate your help as I was really looking forward to the new gesture switch virtual desktops.

    Thank you.

    Just got an update via windows update Synaptics update to version 19.3.11.37 - it finally allowed me to have the film 4 finger to switch virtual desktops!

  • HP Jet 11 - d 010wm: touchpad not working not

    Hello

    I have a HP flow 11. I have upgraded to Windows 10 and had no real problem until I decided to update the drivers (I sent a message that drivers were outdated). I generally don't click on something like that because it causes problems and it was obviously the case.
    After the update, the touchpad stopped working. I tried various fixes, but nothing has worked.

    At one point, I went into Add / Remove programs and remove the touchpad Synaptics hoping that, when I rebooted, restart located the touchpad and the driver and reinstall correctly. I was wrong and I think it was a huge mistake on my part. Now I can't get the driver to work I downloaded.

    Is it possible that I can get the touchpad to work again. I use a mouse and that works fine but not effective for a laptop.

    Thank you

    Alisonf1

    There are five drivers chipset on hp.com for 11 stream and one is required for the touchpad work, I think it's Intel series IO driver without the support of connected intelligence.  Who install and reboot and see if that fixes it and if not, install the other four.

  • Satellite A100 PSAAR: Synaptics touchpad not working not not on Vista Ultimate x 64

    I decided to upgrade my XP 32 bit Vista x 64 Ultimate on my PSAAR A100.
    Operating system works perfectly except one thing - touchpad, which work perfectly under XP, is not answer at all under Vista x 64 (with SP1 of course).

    Worse, it's that my touchpad (Synaptics) is listed in as a work Device Manager correctly. Hmm - I don't remember. Meet your possible suggestions - I tried to reinstall, I tried to use the A200 drivers (since Toshiba does not support drivers for Vista x 64 for line A100) and even had the newer drivers from the Synaptics site. Update Vista even me has new drivers - cool, I admit, but it still does not work, even if Windows does not seem to "know" about any help would be very appreciated :) it...

    PS (optional problem) I also have 2 unknown according to Device Manager devices - since I have no idea what they are, and because I don't think I'm missing something - I simply gave up on top of those - at least for now ;)

    Of course, nobody here the solution for you. :(

    Problem is that this model of laptop is not supported for Vista 64-bit. I don't really know what you can try. Maybe install driver designed for A300?

    I don't really know. You can use an external mouse with success?

  • Touchpad not working not not Z580

    Hello.

    First of all, I hope that my post is placed in the right place.

    Since yesterday my notebook computer touchpad (Z580) stopped working after full initialization of Windows 7 (I can use it for a few seconds) so I know it is not a material thing. I've also updated my drivers, still the same problem. And I can still use a USB mouse.

    I searched the internet a solution but without success.

    I have my laptop for about a year and I'm very happy with it.

    Hope someone knows the answer.

    Jeroen.

    Tanks, but since this morning my touchpad started working properly again without doing anything special.
    I don't know what started the problem, I tried many different things without success, I also restarted my laptop several times yesterday, nothing worked.
    But I'm glad its not now.

    Thank you for your support.

  • Y500 two-finger-tap touchpad not working not

    Hi I bought my Y500 a few happy days with her and there are in general. However, one day the two le deux-doigt-tap (par clic droit) sur le pave tactile - finger - tap (by right-clicking) on the touchpad stopped working. Here is a description.

    Everything else as far as I know, including the two fingers scrolling and the tap of a finger, etc. work well, but the tap two fingers stopped working even though it worked fine for a few days. I have a suspicious as to what caused it, but I'm not entirely sure. In any case, I think that it is probably a bug and probably software. One day I went into 'control panel'-> 'mouse'-> 'device settings'-> 'settings... '. "->"Scrolling"->"two fingers to scroll"->"enable cabotage. I played with the cabotage for awhile and soon off again because I don't really like it. However, that's when I noticed that my tap two fingers stopped working. I have double checked that 'control panel'-> 'mouse'-> 'device settings'-> 'settings... '. "->" by clicking on "->" click two fingers "is set on" secondary click (context menu, drag special) ", but the click two fingers still doesn't work, even after a reboot. I downloaded the latest driver (version 16.2.18.0) and it still doesn't work. I uninstalled the driver and installed it again and it still does not work. Now, I like to use the touchpad, but really hate to live without tap with two fingers for a right-click. Please help me with this, I thank you in anticipation.

    It seems to me a solution, but I don't know exactly why he has solved the problem. It seems that the problem might be that while the Synaptics touchpad device is a PS/2 device, it keeps software interference (of some sort) by being recognized as a SMB (System management bus) device. Which solved the problem for me was to go to 'device manager'-> 'system devices', locate "Synaptics SMB driver", and either disable it or remove it. The two-finger-tap touchpad must begin to work immediately.

    SOLUTION

    So guys after a thorough research and troubleshooting, I found that you must keep the opinion of a few things at installation time:

    Installation mode: UEFI (only) - LEGACY would create problems touchpad.

    After the installation of windows just follow the hierarchy of driver installation

    1 Intel NB_Chipset_M Baytrail-M

    2 Intel i/o driver

    then the rest of the shit.

    Note: after doing all this make sure your touchpad is active > Fn + F7

    Just wanted to if this solution came from an Executive of acer, the world would have been a better place , but in any case this is what the community is for.

    Enjoy everyone
