G780 keyboard does not work, but ONLY if the Elan Touchpad driver is installed.

I have a bad surprise today--unlike other manufacturers, which offers one year free tech support, Lenovo does not. $179 for a contract or $89 to cover an isolated incident. Thank you, guys. :-/

Here's my problem.

G780, bought last October. Upgrade to Win7 Home Premium Win8 Pro.

A few days ago the integrated keyboard has stopped working. It works in the BIOS, but when you start in Windows, Windows does not recognize it.

There is a PS/2 keyboard driver and device keyboard HID that appear in Win8 Device Manager. I guess these are the drivers for the built-in keyboard. If I plug in a USB keyboard, it appears in the device as an additional device keyboard HID Manager.

By trial and error, I discovered that the keyboard still works fine when the Elan touchpad driver is not installed. The problem with THAT: I can not disable the touchpad unless the driver is installed, and if the touchpad is not disabled, it will screw me up because I accidentally brush my hand against the touchpad while typing.

I also noticed that sometimes the touchpad in the system tray icon with a WARNING icon overlaid on top of it (you know, the little yellow triangle with exclamation point). I can't understand why, and I can't understand what has changed on my computer that caused the keyboard to stop functioning properly.

I tried uninstalling the Elan touchpad driver, download the latest driver from support G780 web page and put it back. No luck.

I make do with a USB keyboard at the moment, but I really need this problem is resolved.

Thanks in advance.

So I had uninstalled the drivers of momentum earlier... yesterday I tried to reinstall those supplied with the computer.

At least the keyboard worked now, but the drivers have not been properly disable the touchpad when I plugged the mouse.

Then I hit Fn - F6, not really thinking that he would do anything, but it fixed the problem.

I would have but the pilot would have overridden some setting I put with Fn - F6, but... maybe not.

Problem solved.

  • Research of a window does not work (but only when the folder is indexed).

    As the title suggests, I can look perfectly fine and find EVERYTHING in a folder with even the most detailed search operators, but only if I index the file. I had the same problem with Windows 7 as well and I don't know how to get around this problem. I think it may have something to do with the case in question is on an external drive but I still don't understand why this is the case. Indexing is supposed to make the search faster for a specific folder, but no matter what I do, Indexing always brings Vista only returning "no matches" for each search query. If I was of the same type in one letter, he found nothing.

    Assistance would be greatly appreciated.

  • Keyboard does not work after authentication on the RDS Session host

    When you connect to the RDS through the access portal or app keyboard does not work after authentication on the RDS session host. Offline authentication works very well, past will guide you to the RDS host, then when you try to reset your password, the keyboard does not work.

    Has anyone else had that... ?

    Options (some better than others!) are:

    2. have an application named "Reset your password" (or similar) which uses MS Seamless.then you can leave other applications, as they are

    3 disable authentication carried forward and implemented our service reset password instead so people reset their password before can connect you.

  • Satellite C660 - keyboard does not work but the Num and caps lock shift are on

    I have a Satellite C660 which was working fine this morning. When I came home from work and he turned, the keyboard does not work and therefore can not enter my login information.
    The Num and caps lock shift are turned on.

    Any ideas on how to solve this problem?

    Hello

    You are able to disable the CapsLock and NumLock?
    You can access the BIOS by pressing F2 by turning on the device?

    If this does not work, I would recommend checking an external USB keyboard.
    If the USB keyboard would be functions, then this means that the internal keyboard is defective and must be replaced.

    Hello

    1. did you have backed up your data before attempting to reinstall Windows?

  • Keyboard does not work when connected to the internet

    MY keyboard for some reason any works offline as if it was supposed to, but when online, he goes haywire, instead of typing the letters he hit numbers?  now, I have tried nothing troubleshooting the problem.

    Looks like you may have a virus or other malware. Get your updated antivirus program and boot into Safe Mode. Note that some viruses can hide from your normal antivirus program, so you really need to scan in Safe Mode. To enter in Safe Mode when you turn on first, press F8 on every seconds until you get the menu, and then select Safe Mode. Then run a complete system scan.

    If that suits him fine. If this is not the case, use system restore to go back to an earlier date at the beginning of the problem. To run system restore, click Start-> programs-> Accessories-> System Tools-> system restore. Click on the box that says show more restore points.

    -

    You can check the corrupted system files. Open an administrator command prompt and run SFC if the above does not help. Click START, and then type CMD in the search box, right-click on CMD. EXE and click run as administrator. Then, from the command prompt type sfc/scannow.

    -

    Finally if all else fails, you can look at the rather cryptic system event log. To do that click on start-> Control Panel-> administration-> event viewer tools. Once in Event Viewer system log-click and scroll entries looking for these "error" with indicator see if you can find guidance on where the problem may be.

    `

    When you get your system in good working condition, I invite you to back up your system up to an external hard drive and make it regular periodic updates.

    I hope this helps. Good luck.

    Hi guys... I have a problem with my Tecra A3.
    Keyboard does not work! I bought the new keyboard but its too does not work...
    I think that the problem is related to the controller keyboard or motherboard.

    How can I solve this problem?

    I agree with you. I think also there is problem with keyboard controller.
    What should do? I put t believe there is nothing you can do everything alone.
    As far as I know the controller is placed on the motherboard and I have fear of service can say that the whole motherboard must be exchanged.

  • Satellite L500 - keyboard does not work

    Hello

    I have Vista L500 with a dead keyboard. This machine has not been abandoned or anything it is spilled on it. I plugged USB keyboard external that works. The laptop keyboard does not work. I flashed the BIOS, update drivers, held shift for 10 sec (read on another forum), reset computer, check the updates of Windows Vista and ran 3 checks of Virus.
    Everything is perfect, just no keyboard?

    What should I check? What is a motherboard problem?

    Thanks for any help :)

    Hello

    Can enter you the BIOS (F2 key) with internal keyboard?
    If it isn't the internal keyboard seems to be defective and must be replaced

    I don t think you can do more. I mean you've tried everything what is possible and if an external keyboard works the installation of the OS should be ok.

    The keyboard can be ordered and replaced from an authorized service provider. Do you know how to contact the guys?

  • How is it, my original keyboard does not work on my desktop, but works on my laptop? And my keyboard works for both laptop and desktop?

    Hello

    I have a desktop computer Windows 7 Home Premium 64-bit with an ASUS M4A87TD EVO motherboard. Recently, I have a problem with my Wired Saitek Eclipse PZ30AU keyboard: when I type, the typical button does not appear on the screen. In other words, the keys are unresponsive. The keyboard is turned on, if the office is enabled/disabled. Even if, at the time, while he was working, the light is always disabled whenever the office is off. I don't know why it is informed, even if the office is off.

    My wired mouse usb works fine. I even tried my USB adapter for wireless network in two USB ports, and I still have the signal, so I guess it works very well too. The on-screen keyboard works.
    However, I tried to connect the keyboard desktop on my laptop and for some reason, what works. I also tried to use a different keyboard on my desk, and it actually works.
    I downloaded the chipset, the driver M4A87TD EVO BIOS 2001 driver and a driver of NEC Electronics Corporation USB 3.0 controller. But first, I had to install the Akamai NetSession Interface. After that I downloaded all three files, I installed the chipset driver and USB driver in uncompressing them, by clicking on each file, by clicking on Setup. For some reason, the BIO 2001 pilot had only a ROM file, so I just deleted total. After installing and restarting the computer, the keyboard does not.
    I want to emphasize that, before even manually, download the drivers, I tried using WIndows Update to install all important and recommended updates. After the computer restarts, the guarded keyboard lights flashing on and outside.
    So, I ask two things:
    1.) how does my original keyboard does not work on my desktop, but works on my laptop? And my keyboard works for both laptop and desktop?
    2.) can I keep I have installed the drivers or uninstall them?
    Thank you.

    Hi, thanks for the response. I have a keyboard and shortcuts will turn off. I'm not 100% sure, but I think I did run by pressing Windows key + LeftShift. I did a few tests now and there is something to deal with the Windows key + Fn (dell laptop). After pressing that firefox combinations see keyboard. WinKey + LeftShift operate again. Thanks anyway!
