If it is brand new then it will definitely be under warranty. Call the place where you bought the laptop and ask them what the warranty procedures are. You may be without a laptop for a week or so but they are obligated to fix the problem by either repairing or replacing the faulty part. I hope this helps. I was without a PC for two weeks for a similar issue but after mailing the CPU/mobo/RAM/PSU/GPU down, they found the issue and fixed it for free as it was under warranty.
