[HP 625 Notebook PC] Fan speed control inactive after suspend to ram and sometimes on reboot

[hife]

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.

hife, thank you for reporting this and helping make Ubuntu better. As per http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdHome/?sp4ts.oid=4173278&spf_p.tpst=swdMain&spf_p.prp_swdMain=wsrp-navigationalState%3DswEnvOID%253D4053%257CswLang%253D%257Caction%253DlistDriver&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken#BIOS an update to your BIOS is available (F.20). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.

[hife (hife)]

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.

[Squama (squama-skin)]

Hi, I found a workaround. Please forgive me for machine translation (I bad with english).

There is an option run cooler using crontab:
###################################################################
sudo crontab-e

* / 2 **** echo 1 | tee / sys / class / thermal / cooling_device [0-4] / cur_state> / dev / null 2> & 1
###################################################################
cooler will be switched every 2 minutes

Squama, thank you for your comment. So your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into a Ubuntu repository kernel (not a mainline one) via:
ubuntu-bug linux

Just FYI, I had the same Problem with my HP625, but as it seems, the new BIOS Version F.50 could have resolved the issue.

Available here:
http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdHome?javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken&javax.portlet.prp_bd9b6997fbc7fc515f4cf4626f5c8d01=wsrp-navigationalState%3DswEnvOID%253D4058%257CswLang%253D%257Caction%253DlistDriver&javax.portlet.tpst=bd9b6997fbc7fc515f4cf4626f5c8d01&sp4ts.oid=4173278&ac.admitted=1408112671951.876444892.199480143#BIOS

I just flashed it, so I can't give very detailed Information, yet. The previously seen bad behaviour with temps of 80°C+ doesn't seem to occur anymore, though.
We'll see.

[Ingmar (madocer)]

OK, sorry, but it seems that I was wrong.
The old behaviour is back, as soon as I use the laptop on battery. Before it was connected to AC power.
That seems to be one piece of the problem.
Will try to gather more info, soon.

acpi -V output:

Battery 0: Discharging, 84%, 01:03:32 remaining
Battery 0: design capacity 3692 mAh, last full capacity 3692 mAh = 100%
Adapter 0: off-line
Thermal 0: ok, 26.9 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 108.0 degrees C
Thermal 0: trip point 1 switches to mode passive at temperature 55.0 degrees C
Thermal 1: active, 75.0 degrees C
Thermal 1: trip point 0 switches to mode critical at temperature 108.0 degrees C
Thermal 1: trip point 1 switches to mode passive at temperature 100.0 degrees C
Thermal 1: trip point 2 switches to mode active at temperature 92.0 degrees C
Thermal 1: trip point 3 switches to mode active at temperature 84.0 degrees C
Thermal 1: trip point 4 switches to mode active at temperature 69.0 degrees C
Cooling 0: LCD 0 of 24
Cooling 1: Processor 0 of 3
Cooling 2: Processor 0 of 3
Cooling 3: Processor 0 of 3
Cooling 4: Processor 0 of 3
Cooling 5: Fan 0 of 1
Cooling 6: Fan 0 of 1
Cooling 7: Fan 0 of 1
Cooling 8: Fan 0 of 1
Cooling 9: Fan 0 of 1

It seems that it somehow waits for the CPU tpo reach ~80°C, with the fan completely OFF. Then it turns the fan on at 100% speed. And that repeats itself every few minutes, depending on load, of course.
BTW, I am running Debian, but this seems to be a Kernel bug anyway.
I don't have much time ATM, but will probably file an upstream bug, as soon as I have the time and the necessary info.
