I have an issue with my Schenker B716 (Clevo W670RZQ1). Everytime I start the notebook out of the suspension state, it starts to make a high pitched noise if the screen brightness is lower than ~80%. The high pitched noise gets more loudly by decreasing the brightness. The loudness also increases if I disconnect the power cable. After a restart the noise is gone until I suspend and wake up the notebook again. My system is up to date and I'm using the xf86-video-intel driver for integrated graphics of the Skylake i7 6700HQ. I have no clue why this happens after I wake the notebook out of suspension. I would be very happy about some ideas to solve this problem.
