Hello. I just bought a new EXP GDC external graphics card for my laptop. After i done all the setup after watching the tutorial in youtube, i try to turn on the PSU which is connected to the EXP GDC itself. I expected the GPU wont turn on since you need to connect it the the laptop. But mine, it's turn on itself, without connect it to the laptop. Am I doing something wrong? Is my EXP GDC broken? I really need your help. BTW I use ExpressCard to connect it to the laptop. Also, when i boot my laptop while the EXP GDC were running, i got a black screen but the startup song plays in the background.
