Weird noise after login - Thinkpad T460 running UM 16.04.10

There is a very short, weird creaking noise right after I completed login on my Thinkpad T460 running UM 16.04.10. Does anyone experience the same problem?

have you solved this problem? i think i read something to repair this issue with just a command line, it was reported as a T460s problem but people said it also worked out on T460. Now i can not find the place where i read it
