I own a Lenovo E555. After the switch from Debian Jessie to Stretch fan stopped working Symptom: overheat then halt circa 90° and fan does not wake up. Booting with acpi=off: fan run automatically when needed as it should. Booting previous Jessie's kernel (I used to be on 4.9.0 Debian's backport) does not solve the issue (could be firmware-related then?) I recently updated the bios to the latest 1.23 version which didn't solve this issue either. acpi=off is not a long-term solution (I do need thinkpad_acpi for webcam & cie) What info may I provide to efficiently debug/solve this problem? acpidumps, dmidecode, /sys/<somethinkg>, dmesg|egrep -i 'cool|acpi|thinkpad|fan...' ? thank you |
