Hi Sifus, need some suggestion for college study

1. Preferred Brand : Asus (Or other suggestion ?)
2. Budget : Around 2K
3. Usage : normal college usage (Business Major), watching movies, a little TheSims4 and other simulation games
4. Preferred laptop/screen size : 15

-Lighter and portable (Less than 2.5kg), Longer battery life (Can tahan around 6 hours or more)

*BTW, someone suggested me to get the Asus K551LB or K551LN. But I really don't know a things about laptop. Hope sifus here can help

Thanks !
