Thunderbolt on X1 Carbon 7th Gen (20R1) not work?

2020-03-19, 10:10 AM

Hi All,

 

I just bought Thinkpad X1 (20R1) and extend display to Apple Thunderbolt Display (using TB 3 to TB adapter) but it did not work (while Thinkpad T470 can extend normally, mean that Apple Display and TB convert adapter is OK)

 

I also tried to update all Thinkpad driver, BIOS firmware, Thunderbolt firmware but it still not work

 

Thunderbolt Firmware Update Utility for Windows (Version 1709 or later) - ThinkPad X1 Carbon 7th Gen, X1 Yoga 4th Gen

Intel Thunderbolt Driver for Windows 10 (Version 1709 or later) - ThinkPad X1 Carbon 7th Gen, X1 Yoga 4th Gen

 

Pls help me

Did you approve the device?

Hi Bananaman,

 

 

1. I check with other laptop (HP Spectre) and it's OK

2. I also tried to update everything with Windows

3. I check in the list as you recommend but there's nothing in the list

 

I use Thuderbolt 3 on X1 > Adapter > Mini Display Port Display, it;s OK

 

Do you have any advice? Can you show me your TP dock

 

Tks so much for your support
