[Technology] Getting my Lenovo Twist s230u to actually go to sleep

I use a Lenovo Twist s230u.  I run Fedora Linux.  It has trouble going to sleep.  It just keeps waking up.  I try to sing it lullabies to no avail. 

After suffering for too long, I sought answers, and found these Launchpad bugs helpful:

For a while, I was just doing the suboptimal:

  • # for i in EHC1 EHC2 XHC; do echo "$i" > /proc/acpi/wakeup; done

after restarting.

I got bored with the 5 seconds it took to run that each time I rarely restarted, so I looked into boot scripts for systemd:

So, now I have:

  • /etc/systemd/system/toggle-wakeup-devices.service

Which contains:




 And I have

  •  /usr/local/bin/toggle-wakeup-devices.sh

Which contains:


for i in EHC1 EHC2 XHC; do
      echo "$i" > /proc/acpi/wakeup;

This still isn't quite optimal.  (Would be nice to work out an appropriate patch to fix this behaviour for all users and submit it, rather than a workaround.)  But I have a Masters to finish, and this is sufficient for me for now. :)
