RE: New Kaby Lake XPS 13: coil whine

Jump to solution

I have a $2000 laptop (i7-8550U with 16GB RAM QHD+, iCoil whiner++) and the coil whine is unacceptable, 2.4.2 made it a lot worse under linux.

I has something to do with CPU frequency.

when I do "sudo cpupower frequency-set  --min 400000 --max 1000000"

than i have hardly any coil whine, but a slow laptop.

when I do "sudo cpupower frequency-set --min 300000  --max 4000000"

than I have horrible coil whine

Dell u need to fix this.

Same issue for me. 9360 i7-8550U, bios at latest 2.5.1, running Ubuntu 16.04 with kernel 4.13 and coil whine is unacceptable. This is $2500 USD here in Europe, really unacceptable. Its not just coil whine, its also crackling and almost mechanic-like noises. How can PC with 0 movable parts except for the fan make so much noise I wonder.

 

Please Dell, do something! This has been an ongoing issue with XPS models for few years!

You should contact Dell to change a new Power Brick.
