ProcKernelCmdLine: BOOT_IMAGE= /boot/vmlinuz- 4.4.0-28- generic. InstallationMedia: Ubuntu 16.04 LTS 'Xenial Xerus' - Release amd64 (20160420.1) InstallationDate: Installed on (0 days ago) I am currently running Dell's latest BIOS for this laptop (v1.1.8)īelow is the output of lm-sensors showing the fans running when the CPU is at a cool 35c I've tried the various BIOS updates that Dell has released, without success. They turn on as needed, and then turn off once the laptop cools down. So essentially, once the fans start they don't seem to ever shut off.įans seem to work normally under Windows 10.

If I suspend the the laptop, and then immediately wake it up again then fans are once again off, until it warms up again. Even when the CPU cools down to below 35c, the fans will continue to run. However, after the laptop warms up under normal usage, the fans kick on and then never shut off again. When I first boot up the machine the fans are off. Running Ubuntu 16.04 on a Dell Inspiron 7559 laptop there appears to be an issue with the fan control.
