Powersave or Aggressive Powersave?

[opie]

PCLOS runs much snappier than Windows XP on my netbook (Samsung NC 10).  However, it seems that the netbook battery is being drained faster running PCLOS than it is when running XP.  I have it running on Powersave when using the battery.  If I set the power setting to Aggressive Powersave from the start, will that noticeably hurt the speed performance?  How does the Aggressive Powersave work? 

If Aggressive Powersave will extend the battery, is there a reason not to go all the way to the Extreme Powersave from the start to extend it even further?  What is the trade-off with Extreme Powersave?

Go back through my how-to for the NC10. You will see how to access the relevant settings page for power-saving, have a look at all the things you can vary for each setting. There is so much user control in KDE4, it's a question of getting the balance right for your machine.

By the way the battery may be drained faster than on Windows but it should still do a good turn.

If it's a problem though (it isn't for me), the way to reduce power consumption is:

To slow down the processor. Make this a setting for one of your powersaves.
To darken the screen
To turn off wireless when not in use.
Not to use external mouse or any other non-powered USB device (though I do).

Would you mind posting the link to your "how-to". Having trouble finding it. Thank you.

try browsing tips and tricks while you wait.

Thanks, think I found it. Tips and Tricks wasn't too useful but searching on "Samsung" posted by "davecs" returned a decent number of hits.

It's here, near the top of the netbook section!!

I followed all of davecs very helpful instructions and then did a little experimentation.  As expected, the screen was dimmer in Aggressive Powersave.  But that is easy enough to adjust.  I found that in normal internet usage there seems to be little difference between Powersave and Aggressive Powersave except when watching videos.  Aggressive Powersave makes the videos noticeably choppy.

An old thread, I know, but just as a heads up, it's not recommended to set your CPU to its lowest speed, but rather to leave it at "On Demand". The reason is that when more speed is needed to finish a process, the CPU will work faster and finish the job in less time, which means the system can more quickly go back to idling / using power-saving functions.
