my laptop hibernates shuts down even if in sleep, but i don t know about a regular desktop. I looked through powercfg, great tip, but it only can change power schemes not their behaviour so you would need to predifine the schemes,. The other problem is that i can't run files from flash, but what i could do is make a button that would send roadrunner a certain command i guess(don t know how to do that :P), maybe one of the skiners can help
/EDIT: it seems you can use powercfg to also change individdual settings
