context: my laptop recently started to fail staying in sleep mode, waking up instantly after sleep.
note: I've tackeled a quite similar subject in this gist.
I've agregated many posts from various places online to make a hopefully easy way to find the culprit and permanently disabling it, without side effect nor hacks.
- list your devices that have the authority to wake up your computer:
grep enable /proc/acpi/wakeup
