Hi there! Is the Thunderbolt or USB-C port not working after updating the BIOS? If yes, is the current BIOS version 1.29? If yes, disable the Secure Rollback Prevention under the Security tab in BIOS. Here is how to Boot to BIOS: https://support.lenovo.com/us/en/solutions/ht500222. Then install the previous version here: https://download.lenovo.com/pccbbs/mobiles/n2cuj17w.exe. Before proceeding, kindly read this: https://download.lenovo.com/pccbbs/mobiles/n2cuj17w.txt. Hope that helps.
