Custom Power Scheme not Throttling CPU
I'm working on deploying new Windows 7 pro x86 computers and I'm trying to get windows to throttle down the CPU when it can, but it isn't always working correctly. The settings for the power scheme that I want are basically highest performance on everything except the hard drive should turn off after 5 minutes of inactivity and the display should turn off after 15 minutes. Instead of reducing the CPU multiplier and parking 2 cores, it will run at 126% (the i7's speed boost thing) with all cores active.
More system info:
Processor: Intel i7 L620
OS: Windows 7 Pro 32-bit
Manufacturer: Coban
Model: M7
It might be something with the hardware since the computers are specialized units, but Coban isn't any help with this problem.
If I create a new profile with the desired settings, the CPU will be throttled usually until I restart the system. sometimes it works longer, but not much more than a few restarts. I have also tried exporting and importing a power plan between different computers and on the same computer and modifying the stock "power saver" plan, all with the same iffy results. The stock power saver plan always throttles down the CPU but only if it's in its default state.
I've seen a few other people with the same problem, but no progress towards a cause or solution. Any ideas?
