Hi have this laptot, a SONY VAIO model PCG-6S3M, and decided to check which OS spends more energy after boot, 5 minutes in idle mode as a experiment
The laptot have dos integrated GPU’s:
And it’s a:
With:
TEST WITH NVIDIA
NVIDIA GEFORCE 8400MB, WINDOWS 7 SP1 => 26-30w
TEST WITH INTEL MOBILE
I did the same test in the nightly build and the power consumption increased slightly, maybe 2-3 watts more

Was that with power saving mode on or off in Haiku?

I`m able to go idle into the 15-20w range in the Pentium 4 524 (Prescott).

With saving power on

Interesting results - thanks for this comparison.

There’s definitely a lot of low-hanging fruit for power-consumption optimization. For example, there’s a bunch of background operations which run every second which could probably be modified to run much less often when in power saving mode (or even reworked entirely to not need “polling.”)
I’m not sure if our power-saving mode even fully activates power-saving mode on the processor, for that matter…

New test now with a bigger machine
CPU: Intel Core 2 Quad Q6600 (4) @ 2.400GHz
3 hard disk SATA
Monitor EIZO S2243W
You have to subtract 55 watts, which is the power consumption of the Eizo monitor.
WINDOWS 7: 160-170 WATTS
