Hello. You have posted on the Laptop Audio discussion board. I suggest that you post on the Customer Care board. Do not include your service tag and contact numbers, because those will be removed as per forum policy. If someone from Dell replies to your post, they will ask you to send them that information via the forum's private message feature.
