For the restore power after failure option in the Bios, most desktops have it, but not all laptops do unfortunately (but they have a battery so are less prone to power loss).
For permanent installations, I like to launch lightjams with the ''-locked'' option. that way no one can tamper with the project.
@Mathieu, does the -locked option make LJ use less ressources then leaving it on a empty grid?
