what happens to current L2 status when we have approved H1B

Hi…I’m currently on L2 Visa status with EAD valid till Apr 2015. Also, my H1b petition got picked up in the lottery 2014-15 CAP.The problem is though i Have a L2 with EAD i did’nt get a chance to work, also my employer who filed my H1b could’nt find me a job till date. But I wanted to travel India in Jan 2015. Since I’m currently not working, can i travel and come back to US on my L2 Visa. If yes, what happens to my approved H1B?..
