Hinge on Notebook

Question

My Gateway Notebook that was purchased at Best Buy in Dec. 06 has a cracked left hinge. Last week when I opened it, it made a terrible noise and then hung and pulled up the back area behind the keyboard. It looks like it could break at any minute. I cannot adjust it without it hanging. Please let me know what can be done. Can it be fixed at the Geek Squad location at my local Best Buy? It is a Gateway Notebook - MX6958
