How to deal with a bully?

There’s this girl in my class that doesn’t like me for no reason. She doesn’t know me and I rarely talk at all to her or anyone else in the class. She didn’t like me since the first day of school. I always bring my MacBook to school and everyone else has school computers. She’s bringing a MacBook now and it’s the same color as mine. She was laughing and talking about me to someone else in that class. I’ve never had to deal with someone like her for the whole 3 years I’ve been at school. I want to confront her, but my friends say ignore her. But it’s bothering me and I don’t want someone who looks like her bother me.
