If there is a display on the VGA port, but not on the LCD, replace the display
assembly (LCD, lamps, and cable).
If the display adapter is bad, the BIOS should report it using beep codes (see
Table 6–8, on page 6–79).
If nothing is displayed, is the display turned on? At boot time and while using an
external monitor connected to the NLX external video port, press F2 to enter the
BIOS setup. The Advanced Video Configuration menu lets you select PCI (LCD)
or AGP (the NLX port on the rear panel). The lower VGA port on the rear panel
is the PCI video port (driven by the same video controller as the LCD).
