Re: mysterious/suspicious internet activity.> After investigating a bit, I found that I can write to Re: Can't control Dell laptop fan anymore.Users mailing list - unsubscribe send an email to Code of Conduct: None of the above works out of the box, but I'd consider that a There are some user space tools that can directly manipulate fans if Problem, then we need to look at a possible kernel regression. Problem, I suggest a thermald bug report. Thermald and see if the same behavior still happens. If the thermal behavior isn't correct with thermaldĮnabled in a default configuration, then the next test is to disable Thermald improves thermal management, but at least to not do worse I'd give that a chance to work (orįail) on it's own without anything else competing. I suggest making sure the logic board firmware is up to date as a first step. Quite a lot of thermal management is split up into different areas:ĬPU itself, ACPI, logic board firmware, kernel, and user space. > Here's a snippet from running 'sensors': > sensor directly (like the Dell hw test does), but I don't know how. > What I'd like to do is to manually control the fan and look at it's > So I know the fan works, and presumably thats why the hw test > [I ran the Dell BIOS hardware test routines, and they spun up the Maybe it was overheating that that's why it was getting flaky. > When I did, I noticed that it was reporting a fan speed of 0 RPM. > After running it for a while it started running flaky, First my disk drive died, and now I've replaced it
