NMS is a faceless application that forces system sleep at a set idle time or on Screen Saver activation. It can simply follow Energy Savers settings in an "install and forget" way or operate completely independently. For me this solves the recurring problem of an invariably corrupt power manager preventing automatic sleep and the frequent dead batteries that result. Simple as this solution is it has worked great for me. My laptop ALWAYS sleeps. As a response to user requests NMS now has provisions to allow relatively fine per-application control over holding or delaying sleep and correctly accounts for unattended but more...

I use LightsOut to solve this problem and it works flawlessly. NMS is a bit of a strange UI for me.

I was going for either irritating or seizure provoking. I guess I'll take strange...

I can understand the need for such an application, but I have never had sleep issues with my laptop. It hasn't been shutdown/restarted in 6 months. Closing the lid always works.

With few exceptions everyones laptop sleeps when closing the lid. Sleep in that case is more of a hardware event than a software one. Also my laptop is rock stable.

However I am not supposed to need to spend time manually doing my laptops energy management. If someone knocks on my door, screams to come watch this replay, or all those other distractions and I forget to tell my laptop to sleep I come back to 20 minutes less battery life. My Email app automatically checks for mail every 5 minutes and notifies me, iSync syncs, Software Update checks for updates, all so I am freed up from needed remember and do those things myself.

NMS is meant correct failures of automatic unattended sleep, but do so in a way which is low impact, minimal, safe, free, and dependable. NMS assumes manually sleeping the system works fine, since, of course, that is what exactly what NMS does.
