See page 11. And to answer your question, the idle process executes the HLT instruction.

Then again...my laptop is a Dell.

Certain models of the Dell laptop do downclock. Company name has nothing to do with it.

all programs put the same load on the CPU because the CPU must always be executing code.

Lets take a look at this:

If all programs use the same cpu load then why would running games drasticly decrease the time? You can blame some of it on the GPU, but thats "always executing" too, no?

I exagerated a little :roll: with the 15-45 min, but dont expect it to last too much over one hour if your laptop is designed for use with games. and for battery life to decrease.
