Trackpad at macbook pro cracked
Trackpad at my 13" macbook pro ( 2011 model) cracked 6 months ago and i have to use an external mouse. Just a few days, the bottom base left cover of the macbook pro opened up and bent with gap of 6mm wide. Please see photos attached. Is it due to manufacturing defects and how should I do next? Please advise on the next course of action.
Thanks.
MacBook Pro (13-inch Early 2011), OS X Yosemite (10.10.3)
