Hey Jess,
We are sorry to hear that this happened with your IdeaPad Slim 3 Chromebook. If the screen was damaged due to an accident or handling, you could work with Best Buy to help determine if your purchase is protected by their device support and protection coverage. If this is not the case and your device is not covered, you can contact Lenovo Support online at pcsupport.lenovo.com or at this number: 877-453-6686, to work with someone who can share your repair options with you. 
Please feel free to reach out to us with any other questions!
