I had this issue with my VivoBook S400CA touch screen and fixed it today doing the following:

  1. Go to the Control Panel.
  2. Go to Troubleshooting (you may have to search for it)
  3. Click Hardware and Sound
  4. In the Device section, click Hardware and Devices
  5. Have the wizard scan your computer for hardware issues.
  6. Let the computer fix whatever issues you had.

In my case there were 2 USB input devices that were disabled that the wizard enabled for me.  The touchscreen immediately started working.  Hope this helps someone.

UPDATE:

The problem used to come back periodically.  But since updating all of my drivers a while back, the problem has not resurfaced.

    Hi again,

    I am getting quite desperate here...

    My problem:

    Touch screen worked perfectly fine, then suddenly it stops working. Disappears from Control Panel. "Hardware changes might not have been detected" on the troubleshooting wizard.

    The weirdest thing of them all is that it was working INTERMITTENTLY, without any discernable cause to stop/start functioning.

    I have tried updating BIOS. No new compatible BIOS version available.

    I have re-installed Windows. This did help for a while. Then in the middle of a session, the screen stopped working. I noticed a bunch of windows updates had been downloaded and some installed. So possibly this could've made the touch screen not work.

    Now I am thus back to start.

    I have a new ASUS Zenbook U500VZ.

    Any help would be highly appreciated.

    Thank you.

    ASUS Zenbook U500VZ.

    Can you get any more details about the manufacturer of your Touch Screen than "multi-touch screen"?   That would possibly help you find updated drivers or more troubleshooting tips for it.

    Three possible sources that I can think of for PnP info:

    1. msinfo32.exe  (do a Find for Touch)
    2. dxdiag.exe  (Input tab)
    3. devmgmt.msc  (HID or USB but others could be possible too)

    HTH

    @Robert Aldwinckle

    Thank you for getting back to me.

    I have also tried uninstalling all the updates of that day. Which proved to not help at all. Still the touch-screen doesn't want to work.

    I even paid for RadarSync and updated all my drivers. No changes.

    I did the search you suggested. I'm not sure what to do with the information though, since I didn't get anything conclusive.. Here are the fruits of my search for more info about this "eminent" multi-touch screen of mine:

    1. msinfo32.exe

    Under active programmes I found "aspatchtouchpanel64.exe", with "not available" under all info headings (anyways, I guess this one is for the touchpad, not the touchscreen).

    Under services I found "Touch Keyboard and Handwriting Panel Service", which was marked Stopped. It lead to a file "svchost.exe -k localsystemnetworkrestricted". No info about manufacturer etc.

    1. dxdiag.exe

    Under the input tab I have the following.

    DirectInput-devices:

    Mouse. ("info missing")

    Keyboard. ("info missing")

    ASUS Wireless Radio Control.  ("info missing")

    Input-related devices:

    USB-devices-> USB-rotnav (hub).

    PS/2-devices-> Keyboard Device Filter. ASUS PS/2 Port Clickpad.

    1. Device manager

    HID-> HID-compatible device (location: ASUS Wireless Radio Control).

    USB-device-> different USB devices (USB hub, USB-rotnavs, intel(R) USB enhanced host controller.

    I did have a look through all the previous comments and tried them. My question would be a book long if I listed each and every one in turn.

    When reading your input, I was not sure what you meant by (and how to perform) "reverse the controller" under the mouse device.

    Thank you for the input so far. Hope there can be a solution to this.
