[Bug 1315836] Re: [HP 625 Notebook PC] Fan speed control inactive after suspend to ram and sometimes on reboot
I understand, but I am currently not willing to take the risk of
performing a BIOS update without preparing a working backup system on a
different machine. In combination with my current schedule, this will
delay further input from my side for a while.
Thank you for understanding.

Title:
[HP 625 Notebook PC] Fan speed control inactive after suspend to ram
and sometimes on reboot
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
After resuming from RAM and sometimes after rebooting, fan control
appears to be inactive, resulting in no fan activity at all until at
85°C the fan kicks in at full speed for a short time, only to cease
all activity again until the temperature reaches 85°C again.
This started occurring after upgrading from Ubuntu 13.10 to 14.04 LTS.
Identical behaviour on kernel v3.13.9-trusty.
I have regrettably already removed older kernel versions, so I am not
able to verify that the problem does not occur with them.
I am currently partially circumventing the problem by having
*/2 * * * * echo 1 | tee /sys/class/thermal/cooling_device[0-4]/cur_state >/dev/null 2>&1
added to crontab -e.
