Comment 43 for bug 1161962

I was having this issue in a Inspiron 14z 5480 , Intel Rapid Start enabled.
I had a script turn off all usb wakeup events before suspending and logging the result of rtcwake -- with all disabled, the laptop would still wake up.

After I saw laptopmode-utils doing all sort of stuff before suspention, I uninstalled it. Haven't had one unexpected wake up for 5 days.

Ubuntu 13.10 , kernel 3.11.0-23-generic
