USB type C charging and Thunderbolt issues (after drive and firmware updates) in X280

Hi all,


After reading a critical flaw in the USB-C firmware of Thinkpads, my X280 included, I followed the instructions from

https://pcsupport.lenovo.com/sk/en/solutions/ht508988

 

and even tried replying (I could not reply, maybe the thread is locked...) in this related thread: https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/Updated-Critical-Intel-Thunderbolt-Software-a...

 

At the moment I am stuck with my X280 (with Windows 10) not charging via the USB-C port or the USB-C thunderbolt port... 


I also keep refreshing Windows Updates and Lenovo Vantage, both not giving me anything about firmware and Thunderbolt updates...

 

For now I will try the firmware  n20uj21w.exe from the Lenovo download site here: https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-...

*Why does Windows 10 nor Lenovo vantage tell me about this firmware update? My BIOS firmware version remains at 1,35 even after refreshing Windows Updates and Vantage...

 
Please help...

Re: USB type C charging and Thunderbolt issues (after drive and firmware updates) in X280

Quick update: Now my BIOS version is N20ET51W (1,36) from N20ET50W (1,35) and still no charging via my USB-C ports...

When plugged in, Windows says I am plugged in but no charging occurs...

And we're back...

Move delayed but still coming
