Laptop recommendations needed

Hello,
I am in high school and soon I will heading to college. I am looking for a laptop that will help me in completing various assignments plus allow to have a little fun too like video recording myself and uploading it to youtube. I need it to have lots of battery life and all the other stuff that I have little knowledge over but need. Also let it be budget friendly because I will be paying for it myself and i'm only a teenager that works every other weekend babysitting. Last but not least, a laptop without difficulites with moving the "square mouse thing". Any and all recommendations are welcome. ^.^ Thanks
