p52s and thunderbolt firmware

I tried to update my thunderbolt software and as a result, anytime i plug my charger into the USB-C Connector - the one closest to the rear of the machine, the screen wil cycle on and off indefinitely. It will work normally in thunderbolt 3 connector, the one closer to the front of the machine.

Hi! President89! Try running the update from the Lenovo Vantage app and install all available updates then restart the computer. If the issue persist, run the hardware test from the same app. Update us how it goes.
