(lorenzo@masellis.eu) --- I confirm the same bug on E555. Fan speed is always reported as zero. Writing fan speed (with acpi on) is n= ot 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, t= he fan slows down to minimum speed and does not change speed any more. With acpi=3Doff, the fan is effective. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
