Intel® PowerInformer


What is PowerInformer?

Have you ever noticed a sudden drop in the battery life of your laptop, and suspect it’s the result of the application you installed last week?

Have you ever wondered whether your application satisfies that 2-hour while-on-battery runtime requirement?

Have you ever tried to use Perfmon to gather power related statistics and given up after suffering serious information overload?

PowerInformer is a tool developed to provide basic power relevant statistics to a developer. They can use these statistics to optimize their application such that it matches battery life constraints (e.g. the game must run for at least 90 minutes on a notebook with a 56 W hr battery) while also meeting performance requirements.

Some of the main features include calculating the average residency and the percentage time of the C1, C2 and C3 states of all logical processors.  Also, the screen layout has been redesigned to accommodate more data and to make it look better.  Finally, important data such as disk and file I/O operations have been added to provide more information about the system power consumption.
