ok just got a hp pavilion dv5-1004nr notebook http://www.compusa.com/applications/SearchTools/item-details.asp?EdpNo=4251730&CatId=4948 no i didnt get it there. the vista crashed and my brother in law gave it to me because he bought a new laptop. any way i put windows 7 premium home 64bit and works fine. my question is in cooling settings what is the difference between passive and active and what setting should i have it set too. it does tend to run a bit hot. the processor is set to 5%-100% both plugged in and battery. someone help this is my first laptop and not too familiar with laptop settings.
