STLVNUB Posted December 8, 2018 Share Posted December 8, 2018 This happens when USB stops working. Try USB in another port, it should continue if that port works. 1 Link to comment Share on other sites More sharing options...
itranger Posted December 8, 2018 Author Share Posted December 8, 2018 Thank you for your prompt reply. I've tested now every USB-port but it doesn't work. But I've recognized that this error appears after some AHCPI - Errors (see picture) Link to comment Share on other sites More sharing options...
