So I updated my Thunderbolt firmware some months back on my XPS 15 7590, however whilst it caused problems in Windows 10 causing the idle power to go from 0.2-0.5 watts to 0.8-0.9 watts it was fixed with using System restore and changing the bios to ignore the warnings, Im facing the same issue in MacOS Catalina where it wont idle to 0.3.-0.5 watts it would do before instead 1.09-1.20 watts idle . So my question is how can I fix this because Ive attempted to disable the thunderbolt functionality and it still happens? I really need help because its causing the battery to drain considerably faster than before.
