A Florida woman is seeking more than $5 million from Apple on behalf of thousands of iPhone owners who allegedly bought phones with defective power buttons that would not lock or turn off. In a class action suit filed in San Jose, California, Debra Hilton claims that Apple knew about a defect in a flex cable that controls the on-off button, but chose to stay quiet about it so as to sell more phones. As evidence, she points to Apple discussion forums viewed by hundreds of thousands of visitors on which users complain of “wiggly” power buttons. Hilton also points to a fix-it video on YouTube and comments by a self-described iPhone repairman who says the power button defect is prevalent on the iPhone 4 which went on sale in 2010. Apple did not immediately return a request for comment.
