I ordered a R3000T compaq that has a 3.0GHz w/HT desktop CPU at the time it never occured to me that they would install a desktop CPU in a laptop so I didn't know about it till after I ordered. I really concerned that it might be too hot for me to use on my lap in class and I really want a computer that will go 2.5-3 hours on the battery. I did get the larger 12 cell battery though. Dose anyone have a simlar system that could tell me how there's is? I know this computer will be powerful I just want it to not burn me and have no battery life in school.
