Adjusting energy management settings for longer operation times

I configured longer operation times for my desktop session by the means of the KDE system settings.
Now I am wondering why this system is still put to sleep in shorter time intervals than what I would expect so far. :\

Where should I take another look for corresponding adjustments?

This is too vague :(. Exact description of which parts of System Settings used (I count seven rows of up to seven items, and each of them has from one to four or more sub-items) and which parameters you changed from what to what.

Would you like to take another look according to key words like “power management” and “energy saving”?


Can such settings be kept consistent even if a remote desktop session presentation would be involved? :\
