hello
got the chance to get an powermeasurement device for an day and do tests on my k6-2 system.
system specs1:
k6-2 500, 64mb Sd-ram, via mvp3 board, 40gb ibm hdd, s3-whatever 2d only card, 300watt powerdevice
win98se german + usp2.1 + dx9 + via driver
results1:
'off' = 2,2 watt
boot = ~65watt
idle(desktop) = 58 watt
idle(kcpucooler) = 37 watt (34% overall saving!)
(measurement of complete pc without monitor)
win98se seems not to do any cpu power savings (even when acpi enabled?) when the systems idles, so an kind of softwarecooler should be used.
kcpucooler (free and small and robust)

you could bring your wattage even more down with a K6+ series cpu. you then just need a tool to detect idle status which in turn sets the cpu-multiplier down to 2x.
I am using the mother of all "swiss knife" tools, "power pro", which you can download here . this tool can do a thousand very nice and usefull things beside beforesaid detection of idle status.
for on-the-fly changing of the hw-multiplier you can use k6speed, which you can download right from the downloads section here at k6plus.
