Hi , is there any way of managing the battery more efficiently by being able to underclock the CPU with the press of a button …like the Asus 1000H.
I think Jez mentioned it, but doesn’t one of the FN keys control like silent, turbo and normal mode? I’d guess the silent mode is underclocking – but also the processor should go down to 800mhz when not peaking out.
Yes it does have such a button. Fn + F8 cycles through the different modes. I havent really needed to use it though – the battery generally seems to last for ever already so on a day to day basis you don’t need to watch what you are doing which is really nice.
I imagine it will come in much more handy if you travelling and away from power for longer periods!
i just installed Ubuntu NBR 9.04, is there a way to get the underclocking feature working?
I loved using it in XP but i want to use linux as the only OS
Right click on the panel, and add the CPU Frequency Scaling Monitor.
If you click on the applet which has been added to the bar you can select the frequency of the processor or which governor to use.Bare in mind that although setting it to 800MHz should keep the processor cooler and so make the fan spin less often it may actually negatively impact battery life.
If you want to do this by pressing the Fn + F8 button then you could use the repository or scripts from the Linux On My Samsung site.

Interestingly/Oddly (I think the latter) Fn+F8 does switch Silent/Normal modes, but Silent doesn’t underclock the processor.In Samsung Battery Monitor on my NC10, “Max Batt Life” has the CPU Speed set to Minimum and “Normal” has it set to Auto. Yet if you run BattStat and switch between them, you’ll see the CPU stay continually at 1.6GHz in Silent Mode and only drop to 800MHz when it’s idle in Normal.
So Silent Mode switches to the Max Batt Life power profile, this appears to switch off the fan to extend the battery life, but it doesn’t underclock the CPU to save power or heat. So it’s actually generating more heat than it needs to. Explain that…?

[/quote1244125170]thanks Alfihar! i added all the sources from the link and getting my nc10 close to out of the box in linux
Cheers!
