Hi,

My fan stopped working and I could not find anyway to fix the software to get it working, so I wiped my laptop of Ubuntu 16.04 and installed the latest Ubuntu-Gnome software. This has not fixed the problem.

When I boot I get the message 'ACPI watchdog. Device Creation Failed. -16'

I believe the ACPI controls the temperature monitoring, so it might mean I do not have a hardware problem after all.

How do I fix the ACPI or at least diagnose that that really is the problem?

Thank you
