DELL XPS 12 - Can´t find Touch driver

Hi Gregor,

You can update system BIOS of your computer and check if it works.

Note: Make sure the ac adapter is connected and the battery is charged 10% or above to update the BIOS. Also, disconnect all the external peripherals before updating the BIOS. All the programs should be closed and documents saved.

Click http://dell.to/WrE2G4 to download the latest system BIOS

• Click on “Download File”
• Save the BIOS on your desktop
• Right click on it and select “Run as administrator”
• Follow the prompts on screen to install BIOS 
• Restart the computer. 

If the issue still persists, update video and the chipset drivers.

1. Intel Panther Point QS77 Chipset: http://dell.to/UYp7gO 
2. Intel Management Engine Interface: http://dell.to/QI74Qv  
3. Intel Dynamic Platform & Thermal Framwork:http://dell.to/Trmxmj 
4. Video driver: http://dell.to/UR84PN 

If the issue persists, try re-calibrating the touch on the touchscreen of XPS 12 by following the steps below:

• Select the 'Settings charm' from 'desktop mode'
• Select 'Control Panel'
• Select 'Tablet PC Settings' from 'large icon view'
• Select 'Reset'

Hope this helps . Do reply if you have any further questions. Glad to assist.

Hi,

thank you for the answer. i installed a Windows 8 Pro 64 - German.
I installed yesterday the Drivers from my posted URL. Today i installed again from your posted URLs and get exceptions.

Here the exception from BIOS Installer (i have the newest?! A04 from yesterday):

Here the exceptions from Dynamic Platform and Thermal Framework installer (in english: The setup program could not install one or more device drivers. Setup stops.):

Here my device manager:

What should I do now?

Best Regards,

Gregor

unfortunately there is an obvious issue with the XPS 12.   more and more people are reporting that the touchscreen stops working.  Mine has completely stopped working and Dell support has initiated an exchange for me.  I spend over 12 hours on the phone during their remote troubleshooting and had a dell technician came out to replace the touchscreen....which now doesn't work at all.  it's been over 2 weeks waiting for the exchange to ship

Hi Gregor,

Device Manger of computer has no yellow exclamation and appears to be fine. 

Did you try calibrating touch on your computer following the steps above?

Please share the findings. 

i'm interesting in knowing more about this too, I posted on the other post already ... I also have same issue with replacement touch screen not working

I am having a similar challenge as the one described here.  I reset Windows 8 to factory settings but my touchscreen will not work at all.  I do not even get the option to calibrate because there is no Tablet settings available under the control panel.   One item I did discover under the device manage was a hidden unknown device with the following hardware ID:   GPIO_Laptop-Slate_Indicator   I have to assume that whatever this "device" is, it's causing the issue of the touch screen not working at all. Any ideas?

Hi there I have the same issue, it is recurring with some Windows updates, how can it be fixed?

Regards,

Stuart
