Hi. 

I am using Intel PCM to measure the dynamic power consumed on Intel Sandybrige platform. What it gives me is an Energy Value in Joules.  Is it true that this values is updated every second ?

If so, how to convert this energy value into Power in Watts ??

Will this method be true??

    As Power = Energy/Time

For a reported energy of 2 Joules which is typically reported for my Laptop when just running OS and the Browser , the power estimate will be 

         Power = 2 Joules/ 1 s = 2W 

This seems very odd for a processor to report this low dynamic power 

Can I know what is correct method to read power using Intel PCM ??
