What does the profile Minimal Power Management added by NLite do exactly? Is it essential? I installed a Windows 2003 SP2 system where the power management has become broken. I did check MPM before setup because it did not cause issues with other XP systems. Currently I cannot edit the power profiles on that system. No matter if I create a new one, use an existing as a base, the monitor shuts off after a couple of minutes, which is not good for its health, the settings I choose are dropped. Apparently profiles cannot be imported from XP because they have a different length. But it is not serious issue enough to reinstall the system, which won't necessarily solve the problem. The issue could also be unrelated to NLite.

AFAICR, Minimal Power Management is one of the 6 "standard levels":

What happens with powercfg?

I misremembered the name of the created preset. It is called "Limited Power Management". I believed it to affect the power of the processor when idle, but I doubt it. In PowerCfg, when I change the setting for "Turn off monitor," the setting becomes blank when I load PowerCfg again.
