1/ [QUOTE=Trashbuster from Ten forum] I had the very same problem after installing Windows 10 on my son's Toshiba Satellite L7750-S7340 Laptop. The top row of number keys (1 - 4) didn't work, and my space bar would only work if I pressed it with the "FN" key. There may have been other problems, but I was focused on just the two previously described.I did all the usual trouble shooting things with no luck, although I noticed something wierd in device manager and returned to it after exhausting all the tips found on boards. I had noticed that my keyboard was listed as Lenovo and it had mouse drivers too; showing the mouse was Lenovo, as well.I have been using a Microsoft wireless mouse (with USB dongle) and my keyboard was always Toshiba. So I removed the Lenovo Keyboard (and drivers) and the Lenovo mouse (and drivers) from my system. I rebooted and upon start-up everything was running normally again. Try this and see if it works for you. GOOD LUCK![/QUOTE]2/- After installing windows 10, windows start to download and install update . I seeSynaptics pointing Device driver version 220.127.116.11 (for Lenovo) conflicts with my laptop Toshiba Satellite L775D-S7226 . Problem is after updating (installing) some keys did not work such as number keys 1,2,3,4 and spacebar.So I enter control panel, choose Uninstall program and click Synaptics pointing Device driver (this version for Lenovo keyboard, although my keyboard is Toshiba) to uninstall it. After that my keyboard get back to normal.After that I get in Toshiba webstite and download touchpad driver (Synaptic pointing Device driver version 18.104.22.168) for my laptop, I installed it and see the laptop works normally.But widows update continue downloading the synaptics driver update for Lenovo pointing device into my laptop, so I have to stop it by change device system (http://www.isunshare.com/windows-10/change-device-installation-settings-in-windows-10.html)- Control panel > system and security > System- On the left control panel click Advanced system settings, choose Hardware, click Device installation settings,- Choose No, let me choose what to do,- Deselect "Always install the best driver software from Windows Update", select "Never install driver software from Windows Update" and deselect "Automatically get the device app and info provided by your device manufacturer",- And then hit Save Changes.
Basicamente es ir a Device Manager o Administrador de Dispositivos y en Mouse verificar que controladores estan instalados:
El problema es el: Lenovo Pointing Device, la opción 1 es desinstalar este drive y reiniciar el sistema, el problema es que Windows 10 al volver a iniciar vuelve a instalar el controlador... entonces lo que se hace es anular las actualizaciones automaticas esto se lo hace ingresando a:
y escogiendo NO, se reinicia el sistema y esta vez ya podras usar ¨Espacio¨ y ¨Esc¨ sin necesidad de apretar FN, obviamente que ahora uno tendra que tener cuidado a la hora de desinstalar o actualizar controladores y cuidado con las actualizaciones de Windows 10.
La mejor solución es que si tu laptop no esta en la lista de Toshiba, es mejor usar Windows 7 u Windows 8 donde todas las teclas y funciones especiales funcionan bien.
