I have a T470s running Arch linux with wayland, kernel Linux 4.16.7-1-ARCH

After suspend and resume, the fan runs and runs and runs ... and never turns off. The problem is described in Arch wiki, however they don't say how to solve it.

Someone suggested that upgrading the kernel may help, however, 4.16 is pretty recent. I don't want to replace wayland by xorg.

Updating UEFI/BIOS solved the issue.
