A:Answer All ASUS products undergo intensive quality control testing and inspections, this is a random problem. Normally, ASUS provides one year warranty coverage, if product was purchased brand-new, in order to fix or repair any hardware or part that stop working prematurely under normal usage. If help is needed, you are most welcome to call Product Support Hotline at: 1(888) 678-3688. Also, you can chat with an ASUS live support agent at: http://bit.ly/AsusLiveChat.
