Hello.. I bought this product few week a go, i tested on my laptop is perfectly work ( Vaio VGN-CS16G n Gigabyte 6670 ). Then try to my friend laptop n another vga ( Lenovo series n His Turbo 7790 ) n it's work. Until i use my laptop ( Vaio VGN-CS16G ) n ( His Turbo 7790 ) at the first time it can't detect this product. Then i Unplug the express card several time without shutdown my laptop n stiil won't work. Then I try my first configuration but my VGA fan won't move either and my laptop not detect the hardware, no like my first try. My Question is, did Unplug Express Card without shutdown the laptop will couse hardware malfunction? And my EXP GDC Express Card series can't boot my VGA but if i use usb drive in this product it work, Any clue or Solution ?
