When a machine goes into the suspend state the kernel freezes (stops) user space programs and kernel threads. Then the kernel will traverse all the devices and calls the suspend methods on each driver. Each driver has the know-how to put the hardware into a deep sleep state (or even power it off) (and the converse to bring it back to a sane running state ...

I just went through this exercise with thermald. First, I should point out that thermald was broken, even in fresh versions of 16.04, as it would not read its configuration file. This has now been fixed, so make sure that you have all of your updates installed. Also, the page you reference is pretty good, and also contains an example thermal-conf.xml ...

You can check the power management status by iwconfig. You can enable power management manually using iwconfig, or install laptop-mode-tools, where it will be automatically set on. Another workaround ...

I had the exact same problem a few months ago, I resolved it by installing : sudo apt-get install laptop-mode-tools. I'm not sure why it worked but I forgot to care Other thing you could try is disabling the Wake-On-Lan feature of your motherboard, if the solution above doesn't do the trick.

While viewing videos on my htpc, the screen would blank after 10 minutes with no keyboard/mouse input. Obviously not desirable behaviour for an htpc. Turning off screensavers and power saving did not have any effect. Eventually, my web searchs led me to believe this was caused by the xserver.
