Q. Is there any mobile power management tool available to force the CPU in various power management conditions such as HFM and LFM?
A. If you are a software developer and are comfortable using APIs, Microsoft has some APIs for Windows* that allow some control for this. See: PowerCreateSetting() and PowerSetActiveScheme(). However, it isnt recommended generally that an application use these APIs because they affect all applications on the system, which may not be what you want.
