Serious power consumption issues, any assistance appreciated...

Powertop stats

System baseline power is estimated at 24.3 W

Power est.    Usage     Device name
  10.3 W    100.0%        Audio codec hwC0D0: Realtek
  3.26 W    100.0%        Display backlight
  3.26 W     20.0%        Display backlight
  3.26 W      0.0%        Display backlight
  2.90 W      4.4%        CPU core
  753 mW      4.4%        CPU misc
  384 mW     17.7 ops/s   GPU core
  100 mW      1.2 pkts/s  Network interface: wlp3s0 (iwlwifi)
 75.7 mW    100.0%        Radio device: iwlwifi
 27.2 mW     17.7 ops/s   GPU misc

As you can see I'm having some serious power consumption issues.

Audio codec at 100% and 10.3 Watts (Muted and no audio playing...)
CPU core at 2.9 Watts Idling...
Three seperate backlight entries each consuming 3.26 Watts (/sys/class/backlight/ contains acpi_video0, acpi_video1 and intel_backlight)

I've tried many things to no avail, laptop-mode-tools, TLP, powertop, pm-utils... I'm running out of ideas here.

Any help at all would be appreciated. Thanks

Edit: I'm running kernel 3.14.23-1-lts.

Did powertop tell you that there were improvements you could make to settings to reduce power consumption?  Keep tabbing over to the last section and you should see good/bad things that you can change to decrease power usage.

Yes I've tried using those, unfortunately almost no difference.

Re: Serious power consumption issues, any assistance appreciated...

Maybe a bit of information about the hardware you are running on might help...

Re: Serious power consumption issues, any assistance appreciated...

I imagine it is because you have an optimus machine and the discrete card is just sitting there sucking up power while doing nothing...

Re: Serious power consumption issues, any assistance appreciated...

Bump.

Looks like the problem may be related to a greater underlying issue...

>systemctl status systemd-modules-load

Edit: I've managed to fix this issue. The power consumption still remains... insane.

Re: Serious power consumption issues, any assistance appreciated...

So I've managed to fix a few things here and there, the only thing that remains is high Display Backlight, it's sucking up 10+ Watts at any given time...... This is absolutely ridiculous that I can barely get 3 hours out of a 9 cell battery...

Does nobody really have any ideas?
I've spent far too much time trying to solve this stuff...

9.88 W     10.0%        Display backlight
  3.00 W      3.8%        CPU core
  802 mW      3.8%        CPU misc
  342 mW     14.4 ops/s   GPU core
  100 mW    100.0%        Radio device: iwlwifi
  100 mW      1.1 pkts/s  Network interface: wlp3s0 (iwlwifi)
