Hello,
I'm trying to reduce power consumption of a fitlet-iA10. I'm running Windows 7 64-bit and with the computer at idle it is consuming 5.5 Watts (after the power supply).
This is a clean install of Windows. Nothing is connected to the fitlet; no display, no keyboard, no mouse, no USB devices, etc. The fitlet is connected to the internet using WiFi. I'm using a 64GB mSATA drive.
I've tried disabling HDMI Audio and Remote Display in the BIOS, but there was no change in power consumption.
Is there a way to completely disable the integrated video card? Any other ideas?
Thanks!

Re: Reducing Power Consumption
The system idle power levels you are seeing are consistent with the idle power levels I measured some time ago when running Linux Mint. See http://www.fit-pc.com/forum/viewtopic.php?f=153&t=5843
One thing you may try is to enter the BIOS settings and lower the TDP below the default 4500 mW level. Of course, this will lower the system's performance - possibly to a level which is below your requirements.
If you search a bit in this forum, I think you will find where others have successfully disabled non-CPU features in order to reduce power consumption. Disabling unneeded features would certainly be preferable to lowering TDP - from a performance perspective.
Here are some relevant postings.

Good luck.

Re: Reducing Power Consumption
Depending on performance needs, you could experiment with disabling a CPU
core or 2 in the BIOS. The AMD A10 Micro-6700T has 4 cores, but many tasks
only need that many for short periods of time. Thus, those tasks would take
longer. Yet overall power usage may go down.

Re: Reducing Power Consumption
Hassellbear, thanks for the comment. Found an older post of yours and posted some results and questions there.

Arwen, thanks. I'll investigate disabling a core or two to see how that affects power consumption.

Re: Reducing Power Consumption
So I did some quick testing.
With 100% CPU usage I get the following power consumption:
4 cores = 10.7 Watts
3 cores = 9.5 Watts
2 cores = 8.4 Watts
With a sustained load of about 20% CPU usage:
4 cores = 8.7 Watts
3 cores = 8.7 Watts
2 cores = 8.7 Watts
So for a typical use case, unloading cores doesn't seem to save any power.
Unfortunately the application I need to run is single threaded, so decreasing the TDP below 4500 sounds like a deal-breaker. But, I'll try to test that anyway.

Re: Reducing Power Consumption
hello
I installed a fitlet pc IA10 in a sailboat and I look for the way to reduce electrical consumption.
The fitlet is windows 7
I use the navigation program that does not use much system resource
I reduced the bios power to 3,500 mW and also configure the processor core 2 and disables the sound
Still I as a 12 volt 1A consumption is 12W is too
On any other parameter I can play to reduce consumption.
Thank you

Re: Reducing Power Consumption
You can disable any peripheral that is not required in BIOS or device manager. You can try use Windows power manager tool.
