I picked up a Fujitsu lifebook s2110 today :)

am pretty happy with the purchase (Tx DIps and Chaos for ur inputs), and will post a detailed revu' soon :hap2:
However, this is my first experience with turion 64s so plz bear with me o this n00b qstn....

I wan't to switch off PowerNow mode on the CPU when the lappy is plugged in (and want PowerNow to stay on when running on batteries)
However, I can't seem to find any option to do so in the Power options applet.... :(

Can Anyone please help me locate this? or is there any other utility i need to install in order to do this
 
Hm... Never used turions but in A64, the CnQ option works only when the power profile is set to minimal power management. Did you try setting the power profile to something else? Say Desktop or something?

EDIT: Found this using google
PowerNow software for Win XP is included in the driver for the OS. If you want to disable PowerNow then the only ways in XP is to either to disable in the BIOS. If there is no such option the only other way to control PowerNow is by changing the power schemes:

If you set your power scheme to "Always On" - It will disable PowerNow.
If you set it to "Portable/Laptop" - It will enable PowerNow and dynamically control the clock speed and voltage.

If you want total control then you"ll need to use third party tools like RM Clock or Crystal CPUID which operate in the same way as PowerNow - but with your own voltage and clock speed settings.

ugh..but that also means that there'll be no power mgmt when plugged out

let me chk what these 3rd party tools are, else i'llleave the power mgmt on...
 
superczar, their would be minimal effect on your on your tasks even if powernow is enabled, i have my desktop with cnq running, its not going to effect your performance in any way, what do you dont like aboout power now ?

PS: Just a tip, maybe not applicable to you, always enable cleartype for your fonts ;)
 
hmm..just that i thought 'tis funny why there should n't be any options to play arnd with this setting.....

anyway, i guess I'll let powernow stay on

Edit:

Found this nifty freeware tool called Notebook hardware Control allows custom settings for power switching + diasplays core CPU/GPU temps, battery temp and wear levels , battery charge levels, HDD temp and lotsa other stuff....

Guess i got what i needed and then some

Yeah anti-aliased fonts look so much better - even on conventional CRT monitors. I might be taking it to the extremes, but I dislike reading text if cleartype isn't enabled!

Back to the topic: Speedstepping does make a difference. When I worked on the laptop comparisons at CHIP, I remember seeing a huge difference in the 3Dmark CPU scores after disabling CnQ i.e. by setting it to 'Desktop' in the power options.
 
Cleartype (by some other name) was an Apple thing to begin with AFAIK

As for the topic, NHC seems to be doing a good job of letting me take control of the power steppings...

I hav set it to run in full performance mode (no downstepping) when plugged in, and to enable PowerNow when on batteries
