Thinkpad X1 Carbon touchscreen no longer working - it worked for a year

2015-04-19, 10:28 AM

I have looked through all the posts on this and it seems there are 2 threads, one where the touchscreen never worked, and this was often the fact that the ordered model didn't have the touchscreen, and second (my issue) when the touchscreen stops working where it was working before.


My model is 20A7-CTO-1WW - 2014 version - Windows 8.1 Pro.


Before anyone asks, yes, it does have the touchscreen, it has worked faultlessly for nearly a year.


Sometime in the last couple of weeks, the touchscreen stopped working completely.


I reqularly apply maintenance (Lenovo and Microsoft, my BIOS is at the latest level).


When I stated to diagnose the problem, I saw a couple of anomolies.


1) In the "PC Settings", I says "no pen or touch input is available for this display"




I ran the Lenovo Center test, and in the Log File (full log available)...... Index 18 clearly shows the Touchscreen




And finally, if I go to the HID section of Device Manager (+view hidden), there is no reference to the Touchscreen



No reference to the Touchscreen in the BIOS settings,


Please can someone give me some advice, it seems that maybe the Touchscreen H/W has been turned off somehow.


Thanks, in Advance, Paul
