Alienware 14 lights problem

the lights of my alienware 14 don't work now. i have tried many ways including restoring operating system to factory state, updating the bios, re-installing Alienware Command Center trying to fix it but i failed. All the lights including the wifi, caption and battery lights only light  for 3 seconds and then go dark immediately when i open my computer and i click "go light" in Alienware Command Center. oh, i forgot to mention that the light on internet interface on the right side will light and won't turn off when i plug into the wire. So what should i do now? should i sent it to repaire? i just bought it for 4 mouth, i didn't think it would broken so quickly....
