I have the same proble on my HP Envy 2090 and I can't get it fixed and don't really know where to even start.

I have tried fiddling with the above (82, 83 and 84) tricks, but I get a file permissions error:
petteri@ENVY14:~$ echo -n 1 > /sys/devices/virtual/thermal/cooling_device0/cur_state
bash: /sys/devices/virtual/thermal/cooling_device0/cur_state: Permission denied

Is there something I need to change before I set the value for cur_state? The directories and files seem to be write protected.
