Alienware 17 1 year only ( Battery Issue. Plugged In, not charging )

My alienware 17 is new. from 2 week ago it does not charge. The problem start intermittent and I resolve it shutdown the laptop and power it again. Now the system not charge again.

I already do:

Update Bios, Remove battery and press the power botton 30 second, buy new power adapter and not resolve the problem. Run all Dell test and everything pass correctly.
