2x USB C Thunderbolt ports not being recognized on Lenovo 730S












0















The device has 3 ports, 1 of which is for charging. Previously I had Win 10 and the other 2 ports were not being recognized. After some troubleshooting / googling I figured it had to do with the bios and flashed a newer version which solved the problem.



I then burned Ubuntu 18 image on the flash drive and installed it using one of the other 2 ports, everything went fine. After the installation, however, these 2 ports just don't work, only the charging port does. Whatever I insert doesn't get mounted. What's even more interesting, I don't see the devices in bios' boot menu either (which I did when installing ubuntu).



Any ideas on how to solve this?
