m15 R4, keyboard failure

I bought an Alienware m15 R4 for college. Two days after receiving, the keyboard became non-functional. No lights - no response. Laptop works with an external keyboard. That was July 21. Dell diagnosed and confirmed it was a hardware issue and replace the laptop. Kudos for customer support. Now just 2 months later the same issue. New laptop has a dead keyboard, again! Ready to give this lemon back to Dell and get another laptop.

Anyone else had this issue?
