The machine is fix and working fine but I realize the Window sticker are like being peel halfway. To my dissatisfaction as it is a brand new unit I ask for a replacement. After a few email; today I receive it, I was so happy :) never thought the tech support staff will go this far to get me replacement sticker , kudos to him / her !
** yeap I know it is just a sticker :) but it really made my day and prove my decision is right for switching from HP to Dell.
