x60s Power Consumption

I have an x60s and I'm wondering what I can do to increase my battery run-time. Running Mobmeter idling with wireless on and connected and the screen at it's lowest setting, I am using 9.4 Watts. Is this normal? Is there anything I can do to reduce it?

I am running XP pro with firewire, pcmcia, SD slot, ethernet, modem and bluetooth disabled. The hard drive spins down after 30 seconds and I am running 2GB of RAM.

Thanks for the help

Peter

From what you mentioned you have already done there isn't much more to do. The only thing I can think of is to adjust your wireless settings to minimum power. This should also make the palmrest run cooler.

9.4W with wireless on is actually pretty good. Wireless is the worst offender when it comes to battery (after the LCD), so I will agree with Jackboot that the best you can do is lower your wireless transmission power.

maybe lowering the Voltage levels, but donno if possible on LV CPU...

no, Intel Core CPUs cannot be undervolted.

good to know. Can you explain? Or link? Thx.

The whole range of possible voltages is stored in a CMOS-Chip.

In the manufacturing process of the CPU however they get programmed with a Valid Range of Voltages that can not be changed (<-thats pretty much a quotation from the Datasheet).

That means that you can chose any of the available Voltages together with any of the available frequencies but you can not step outside of the boundaries that have been programmed into that particular CPU.
You can never go below the lowest standard-voltage.

I'm using the latest NHC (2.0 pre-release 06) on my X60s (L2400) and I can undervolted my cpu at all multipliers (x6-x10) to 0.95V... (instead of 1.075V which is the original voltage at x10 multiplier)

This 0.95V is the lowest which I can setting up in NHC.

Why able to change the voltage in NHC if these are fixed in hw side...

???

That's the point. You're stuck at 0.95 (esp. at 6x). With the older systems you could go all the way down to 0.7.

So yes, you can undervolt, but it brings alot less benefit.
