Problem with media center and power consumption

I've tried to find an answer to this but I'm not the most technically minded so I thought I'd ask here.

I added my Xbox 360 as an extender in media center. However, this is using a massive amount of power from my laptop. I've gone to settings and disabled what I think are processes to media center, but my laptop is still using way too much power.

Thanks for reading, I hope you can help!

I'm going to bump the thread, forgive me, I'm desperate!
