(lorenzo@xxxxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |lorenzo@xxxxxxxxxxx --- Comment #4 from Lorenzo M. (lorenzo@xxxxxxxxxxx) --- I confirm the same bug on E555. Fan speed is always reported as zero. Writing fan speed (with acpi on) is not effective, as the fan remains at minimum speed no matter the settings. This lead to CPU overheating and throttling. At power up, fan runs at full speed briefly; as soon as kernel is loaded, the fan slows down to minimum speed and does not change speed any more. With acpi=off, the fan is effective. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
