18.04 After suspend fan goes to max speed on resume, have to reset in bios

[Kristofer]

I installed 18.04 on my Thinkpad X260. When I closed the lid it suspended. Opened the lid and the fan went to maximum. I shut down and booted into Windows 10 (dual boot machine) and the fan was still at maximum. I had to reset BIOS to defaults, so it looks like Ubuntu is still messing up the BIOS settings, at least on the X260.

Ubuntu is up to date as of 2018/03/27.

I just re-tested on 4.15.0-13-generic suspending by closing the lid and by Automatic Suspend in the Power settings and upon resume there is no problem, so it seems to have been fixed.

This problem seems to have returned with 18.04 LTS. I left the laptop plugged in and charging and closed the lid. When I opened it several hours later the fan went to maximum speed and has been there since. It doesn't matter if I boot into Windows 10, the fan is still on max. If someone can tell me what logs would be useful I can get them.
