On Monday, October 16th, I bought a notebook from Saturn from the brand Lenovo, which has the exact name 110S. Every few weeks suddenly the problem arises that suddenly the sound sounds like a robot, but it disappears when restarting. I had not had the problem with any other notebook / laptop yet. Today I had the problem again with the Lenovo 110S.
