Each laptop has different power settings as they come from the manufacturer. If you're just using the Windows settings (and not the added on manufacturer's stuff) you should be able to see exactly what it does in the Power applet of Control Panel.
Some things that can be affected by these settings are the screen brightness and the period before the screen goes into sleep mode. This'll serve to conserve your battery when it's not plugged in.
Where is the added on manufacturer's stuff? I don't see that anywhere. I'd like to make sure I'm NOT using that stuff...
I'm looking at the settings you see in the Power Options Properties box (which you can get to from Control Panel, like you said, as well as from Properties on the desktop, etc.).
But I'm not sure what you say is entirely accurate. I actually had my settings accidentally set to Desktop on my laptop without realizing it, and my fan was turning on and off every 40 seconds for about 20 seconds, continuously. I finally figured out what was causing that. However, I had not changed the settings that are listed below in the Power Options Properties box (i.e. Turn off Monitor, Turn off Hard Discs, System Standby) -- those were exactly the same. So there are properties that you can not change that are inherent in whatever setting you actually choose at the top (i.e. "Always On", "Portable/Laptop", "Desktop", etc.). This was also verified to my by someone as being true. And when I switched it back to Portable/Laptop, the fan-issue stopped.
So those options that they let you alter at the bottom are only *part* of the power scheme. There is a part that you can not alter. And that leads me back to my first question as to whether or not "Portable/Laptop" is better than "Always On" and what each has as their inherent/unchangeable settings. Know what I mean? Any thoughts?
And just FYI, for the settings that I can change, I have it set to the following:
Turn Off Monitor: After 15 minutes (plugged in); After 5 minutes (on battery)
Turn Off Hard Discs: After 1 hour (plugged in); After 3 minutes (on battery)
System Standby: Never (plugged in); After 10 minutes (on battery)
Seem okay? I believe the "on battery" settings" are the defaults for those categories for "Portable/Laptop".
Any further help is appreciated!
