SUMMARY
On the systems settings module, I set the laptop lid close action to "Suspend", and unchecked the box "Even when external monitor is connected".
Powerdevil seems to ignore this setting and suspend the laptop whether an external monitor is plugged or not when I shut the lid.

STEPS TO REPRODUCE
1. Plug in external monitor 
2. Close lid

OBSERVED RESULT
System enters suspended state

EXPECTED RESULT
External monitor inhibits suspension.
