kralisec Posted June 1, 2018 Author Share Posted June 1, 2018 Hello, More information: it's not related to the docking station, I have the exact same problem when I unplug power, I did not discover before. Any idea ? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 2, 2018 Moderators Share Posted June 2, 2018 Follow instructions from here to debug issue By the way, you do have Legacy Option ROMs disabled correct? Make sure it is disabled if not. Link to comment Share on other sites More sharing options...
kralisec Posted June 2, 2018 Author Share Posted June 2, 2018 You are correct, Legacy was enabled, I have no idea there is a relation with legacy and freeze with power plug / unplug :( Now I can also plug / unplug from docking, all is fine. Problem solved. Thank you for your help Jake Lo :) Link to comment Share on other sites More sharing options...
