I have a problem with powernap daemon on kubuntu 13.04, which doesn't start with upstart (or with /etc/init.d/powernap start). On my other machine with ubuntu 12.04.2 LTS it starts ok.

$ sudo service powernap start
powernap stop/pre-start, process 8245
$ sudo service powernap status
powernap stop/waiting

I tried reinstalling powernap (with purge), but the problem persists. The only way i managed to start powernap daemon is: 

$ sudo powernapd
$ ps -e | grep powernap
21369 ?        00:00:00 powernapd

The system is up-to-date.

from the service --status -all command I have found something which can help you. 

21369 ?        00:00:00 powernapd

here ? is status of your service and i.e The [ ? ] is drawn for services that do not support the service command. Support for this command is determined by grepping the "Usage" information that is printed when service $SERVICE is run.

so you can not check its status with service powernap status command.

I had the same problem. Edit this file: /etc/default/powernap

Contents: 

# start powernap at boot [yes|no]
START=yes

I don't understand why but start was set to no, change it to yes and it works!
