Keyboard and touch pad stopped working on Satellite L750

My laptop L750 keyboard and touch pad stopped working on start up. I now use a USB mouse and on-screen keyboard to do anything either. I have tried several things to fix, but nothing seems to work.

I've updated keyboard drivers, tried related work key, updated and run antivirus software and restored to a point in time before the show. Still no luck.

Any ideas?
Thank you

Keyboard drivers?
Can you please send the link to download? It is unclear to me that the own keyboard driver.

In any case, can you use keyboard and touchpad if you start the operating system in safe mode?
Are you using the original pre-installed OS that you got with your laptop?

    Hello

    With regard to the problem of keyboard:

    From my point of view of the few sounds of keyboard described as a material problem internal related dysfunction... probably in order to solve this problem, the keyboard should be replaced... just to make sure that your internal keyboard is affected, please join the external USB keyboard and check if it works properly.
    If you see any problems, the problem is no doubt by a malfunctioning internal keyboard and as mentioned earlier, you will need to replace the keyboard.

    Regarding the touchpad:

    I'm not sure if the two issues are interrelated, but the touchpad can be disabled by using the function keys... I recommend you to check this... (function key details are also in the user manual)... you can also try reinstalling the touchpad drive.

    Tip: this forum contains many discussions about similar problems... so I recommend you to read the recommendations posted in this community.

  • Satellite A300-243 - keyboard and touchpad has stopped working

    Hello everyone

    I have a serious problem in my Satellite A300-243. I installed a driver for external keyboard using a CD and once I rebooted both keyboard and touchbpad stopped working and to make any order, when I reached the vista welcome page.
    What should I do because you know that even if I can't get into the windows to uninstall this driver.

    Any way to do during windows startup?

    Hello

    Why you installed a driver for external keyboard? I've never heard of such drivers

    Anyway, you should try to start in safe mode and then you are able to remove driver external keyboard to the list of software. After I restarted in normal mode, the keyboard and the touchpad should work properly again.

  • Keyboard and touchpad do not work on Satellite C870-13F

    I have a computer satellite C870-13th since August.

    Yesterday for no apparent reason, my touchpad has stopped working. (no, I didn't turn off)
    Not really bothered by it, I continued working on my computer for several hours.
    Find it me so that he might be a little bug, so I decided to restart my computer.

    When we turn back, not only my touchpad does not work, now nothing on my keyboard responded, not a single touch. I've updated the drivers, bios, done a virus scan, restored my computer for a few days before, nothing is.

    The strange thing is that the keyboard is always when I press F1 or F8, 0, enter, and arrow keys to get into the menus before windows starts.

    Help them, I used the toshiba recovery to restore the computer to factory settings.
    Despite all this, keyboard and touchpad are still pending.
    I don't really understand, because it works at startup may not be real materialistic damage!

    Now, I'm getting frustrated cause I have more solutions and tapping the screen with the keyboard is really slow! = p

    Any help?

    Hello

    I think that it s a bad material work because you have already tried the system recovery and the keyboard does not work even if you use the factory settings.

    But it would be interesting to know if the USB external keyboard would serve. You can test this? In my opinion if the external keyboard would work properly, then it would mean that your keyboard is faulty and must be replaced.
    I m wondering if the fault of the touchpad is related to failure of internal keyboard.

    However, I think that the guarantee must still be valid if you bought this unit in August. Then get in touch with service and guys should fix it for free!

  • Equium L10 - touch pad stop working (mouse)

    Hi guys,.

    really need your help. I have an Equium L10-300 and my touch pad has stopped working. A few days back, he started to freeze, but reboot solved the problem... but now it has stopped working all together. The icon that normally indicates at the bottom right of the screen disappeared. Have done the FN9 thing and tried to look at the settings...

    Help, please

    Thanks, Pete

    Hi friend

    have you already tried to remove the mouse from the Device Manager? Or reinstall the driver would also be a very good attempt to resolve this situation as a whole.

    The first step that needs to be done is to exclude a software error, then go-> http://eu.computers.toshiba-europe.com/-> support downloads & -> support-> download home page-> download drivers

    Get the driver for your mouse and reinstall. If it shouldn´t work then come here and we will see what could be the next step...

  • Keyboard and USB mouse stops working and kicking in and out.

    Hello

    I'm having a problem with my keyboard and USB mouse. Both at the same time stop working. Also, the mouse freezes every 10 seconds for 1 second (so boring). When the mouse stops working there is still of the red laser that is below normal. I am confused with that. I have all the latest drivers.
    Thanks for the help.

    Hello

    If you have a USB mouse wired and keyboard connected to your computer, and that they do not work properly, please check following things:

    1. Firstly, plug the USB into a different port on your computer. If they still do not work...

    2 try them on another computer! and if the problem is still there, it would be easy for you to just replace. But is not likely to result in the mouse and the keyboard does not at the same time!

    2 and if it's OK with another computer, which would be something wrong with your computer, and it could be from a hardware or software.

    Just see how it is done up to now.

  • Keyboard and USB mouse stop working correctly with Windows 7 Professional x 64

    I originally had Windows Vista x 64 on my computer (he's 8 months old, CPU intel quad core 2.0 ghz, 6 GB of ram etc.). I installed Windows 7 RC in July (new installation) and used until 2 weeks ago when I installed Windows 7 Professional edition (I reinstalled Vista and then installed the upgrade to Windows 7 by using the clean installation).

    In recent days, I had problems with the mouse and keyboard (the two connected USB). Entries to start acting strangely. For example, using scroll in firefox causes the font sizes change in firefox, instead of scrolling and clicking on links opens the link in a new window, not in the same window. Right click stops running. The keyboard input will simultaneously strange - I can type is no longer (for example in firefox search boxes, or WMP), of if I type, it uses another command to open something, etc. I don't understand what is happening! However, after the reboot, the problem disappears and everything works fine, until the next time it happens (has happened 3 x now). I tried my mouse and keyboard in my old laptop and they both seem to work well. I have not received any pilot error / virus messages / dysfunction (Bitdefender 2010) messages of any kind, and as far as I know, all the drivers are up to date.
    Anyone know what is happening? Is there something wrong with my motherboard? And if so, why are there no error message? And why things work again after the reboot? Help, please!

    Hello

    Update the drivers for the keyboard and mouse should solve the problem.

I tried to reinstall all my drivers, hard reset my USB ports, and reinstalled windows, nothing has helped me. Also, if I play a game, nothing changes except the fact that I can't move my mouse or my type anything with my keyboard, if I am skpying with someone, my audio and microphone works perfectly fine, I just can't use my keyboard and mouse. My mouse and keyboard are standard supplied with my computer, the Studio XPS 8300. Regardless of the mouse I use, this always happens.

  • Need number for keyboard and touch pad reference Dynabook C7-

    Hello!
    I have a few questions on my PC laptop toshiba dynabook C7.

    I want to change my old keyboard and the press because they do not work properly. The problem is that I can't find these parts because this model was delivered only for the Japanese market. So maybe someone knows the number of models of these pieces that might be suitable for my laptop? Or the name of the laptop that is similar to my dynabook c7. The full model name is TOSHIBA DYNABOOK C7/212CMEN portege 4101 series

    Thanks in advance.
    See you soon!

    Hmmm... It can be quite complicated. As you probably know it is not easy to get the info on those specific for computers produced Japan portable. I'm quite familiar with models of Toshiba laptops and your laptop can be the same as Portege A100.

    Google around and try to find info on the Portege A100. In my view, that this laptop has been offered to the United Kingdom only.

    Also check in Google - P000398500 G83C0001Q710 for Portege A100 series, United Kingdom, Uk keyboard.

  • Keyboard and Touchpad does not work on Satellite L

    It's the second time this has happened to me
    However the last time a system restore solved the problem, this time restore system did not work.

    I can use my keyboard at startup and in safe mode, but that's all.
    I am currently using a USB keyboard and a mouse.

    I tried almost all the suggestions with no joy. Help, please.

    Hello

    There are not many options that could solve this problem.
    It can be a hardware software or related issue.

    You can use the internal keyboard in the BIOS?
    Select this check box.
    If this is not possible, I guess that the hardware is defective.

    Also I recommend that you test the keyboard and the touchpad using factory settings.
    Grab the laptop and check if the keyboard would serve. Otherwise you will need a help of a technician for laptop to replace the keyboard and the touchpad
