X1 Carbon Gen 7 HDMI not Working / 0x227 SDK_NO_DRIVER Thunderbolt(TM) UWD software is not installed

2020-11-25, 10:09 AM

Hi,

I have an X1 Carbon Gen 7 (Type 20QD, 20QE) with Windows 10 and recently I discovered that my HDMI port is not working. I tried a USB type-c adapter for VGA and HDMI and it's not working either. When a click F7 and then try Duplicate or Extend, for example, there is no reaction or anything in my laptop or in the data show or tv.

So my understanding is that it is not related to the HDMI port being damaged or something. I searched in the forum and discovered that there is a ticket "Critical Intel Thunderbolt Software and Firmware Updates - ThinkPad" and that a symptom of the problem is that the HDMI output not available to project.

I tried the solution by installing both the Driver and Firmware related to Thunderbolt technology but I get an error when I install the Firmware.

N2HTA08W 1.41.648.5 N2HTH03W 43

Error: 0x227 SDK_NO_DRIVER Thunderbolt(TM) UWD software is not installed.

Please install the Thunderbolt(TM) UWD software and run the tool again.

I have this problem too. This morning, found my computer had gone to sleep and both my monitors (connected through USB-C/DisplayPort) no longer work. Computer also wasn't charging from the USB-C although that has resolved itself. Thunderbolt seems missing from Device Manager.
