Keep your ubuntu-gnome from waking up at random

I have tried using /proc/acpi/wakeup and I've tried looking in /sys/bus/usb/devices/SOMETHING/power/wakeup for devices that will wake up the computer, however I finally fixed my random wakeup problems with a tool called acpitool.

It is really quite simple. First you need to install it, unless you already have it installed:

 ~ sudo apt-get install acpitool

Once it's installed you can list what you can do with it, and to make it works.

~ acpitool --help

Then you can list all your devices (small w)

~ acpitool -w
   Device    S-state      Status   Sysfs node
  ---------------------------------------
  1. SBAZ      S4    *disabled  pci:0000:00:14.2
  2. PS2K      S3    *disabled
  3. PS2M      S3    *disabled
  4. UAR1      S4    *disabled  pnp:00:06
  5. P0PC      S4    *disabled  pci:0000:00:14.4
  6. UHC1      S4    *enabled   pci:0000:00:12.0
  7. UHC2      S4    *enabled   pci:0000:00:12.2
  8. UHC4      S4    *enabled   pci:0000:00:13.2
  23. PE21      S4    *disabled
  24. PE22      S4    *disabled
  25. PE23      S4    *disabled
  26. USB3      S4    *enabled   pci:0000:00:13.0
  27. USB5      S4    *enabled   pci:0000:00:16.0
  28. PWRB      S4    *enabled   platform:PNP0C0C:00

Then it's just a matter of disable all the devices you don't want to wake up the computer (large W).

~ sudo acpitool -W 6

Don't disable everything, then you can't wake the computer again :)

I keep the power button enabled. And have configured the computer to hibernate when it's pressed, giving me a nice symmetry.

Windows 10 wakes up from sleep at random

After upgrading to Windows 10, my computer started randomly waking up. This extensive guide on superuser has proven time and time again to be a perfect guide to keep windows from waking up.
