Thank you for your reply.
On this unit, I also have a problem to install the Wifi Card because of the "Magic 2R2" grey chip being placed too low on the board, so I cannot screw the card.
I'm definitely returning this unit.
FYI, S/N is G6YK344000MU Batch CNG63AT103
Date of Manufacture 29OCT2013
I also have one more problem is unit cannot put my screen to standby, so when it standby it constantly wake up the screen with black screen then sleep. I don't know if it's my screen being incompatible with the computer (Iiyama Prolite XB2776QS).
Such a pity, I really liked the design, the size and the power...
