Hi! i installed Windows 8 CP 32 bit on a Dell Vostro 3350, but after the installation the internal screen just blacked out. it wasn't backlight at all. I can only view W8 on an external screen via HDMI, though Windows 7, which i have installed on a another partition, Works perfectly on my internal screen. I have an i3 processor With intel hd 3000 graphics. The installation itself worked on the internal display. Have you any idea what could be the problem?
