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.

    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)

    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.

    Hi there,

    also having a similar problem with my new ASUS U500VZ.

    After an update the touchscreen stopped working.

    this happened exactly to me too:

    I ran the troubleshotting option for hardware and devices but that did not help. The wizard simply says "Hardware changes might not have been detected" and displays a warning icon without actually resolving the touch-screen issue. To further exacerbate the problem, the "Pen and Touch" option has altogether disappeared from the Control Panel.

    I am in contact with ASUS support at the moment, waiting to see if they manage some solution. At the momet they are suggesting updating/reinstalling BIOS.

    Will share it with you guys if that works.

    HI zazi8,

    I have the same problem. After a lot of unhelpful visits to the asus third party service center (fixit, digicom in bangalore) - they have absolutely no idea and are just experimenting on me wasting my time. Asus should have more capable service centers, preferably direct, if they are to succeed in India (big potential if service is right).

    I did a factory reset. Now the touch screen works partially.

    when I boot up the touch screen doesn't work.  a fn key sequence is required after which the touch screen works for sometime. If the system goes to sleep or standby, the touch screen stops working and I have to do the fn key sequence again. See if this helps you.

    1. fn+f8 -> gives second screen options -> chose "Duplicate" using the cursor keys
    2. then again , fn+f8, choose "extend"
    3. again , fn+f8, choose "pc screen"

    voila, the touch screen works ... for some time ... till the system goes to standby or sleep or restart or shutdown

    Please let me know if this works,..... need some solution from Microsoft for sure as the touch screen stopped working after some updates.

    Regards,

    Hey Krishna,

    Let me know if a solution is forthcoming. I did a 'refresh to factory' setting over the last hour hoping it would work but instead the pen and touch tab has not reappeared in control panel nor is the touch screen working at all. This seems to be a much bigger problem than I first envisaged.

     

    Luckily for you, Asus has a major presence in India. I bought my laptop from London and am now in Lahore. If it has a major problem I have no way of getting it corrected.

     

    Ciao
