There have been some forum discussions regarding the non-lighted Kindle cover, and our engineering team is looking into this. Regardless, if anyone is having any problem with an Amazon-manufactured Kindle cover, please call us at 877-453-4512 or 206-922-0844 . We will be pleased to replace it for free with a different cover or accept a return for a full refund, no matter when the cover was purchased. "
