Is it possible to reduce graphic processor power consumption?

My notebook powered with nVIDIA GT230M graphic processor and its power consumption is about 45W, it eats my battery!

Other Specs:

15.6" monitor
4GB of RAM
720QM CPU

The modern graphics drivers include a internal automatic power management. I don't know if this option is configurable in your graphic card.

You can always try looking for both driver, BIOS and graphics BIOS updates in the hopes that they have added this functionality, but, it is doubtful.

Typically, the more powerful the graphics card in the laptop, the higher the capacity of the battery that comes with it for this very reason.

Unless you have Optimus or some other sort of Hybrid technology, there isn't anything you can do :( - Sorry!
