Asus l3c series laptop, Radeon 7000 Video Card, Windows XP Home SP2. The Video card does not recognize the notebook LCD screen as being connected when booted.The FN/F8 key will not switch to the laptop LCD from the attached external monitor .The message is monitor not attached when i try to swich between the external to internal display. Under display settings, the display monitor is not shown as attached and checked off as the primary monitor,but windows xp desktop it is shown ok on the external monitor or tv.If anyone knows how to resolve my problem or has the voltage or schematics from the invertor or motherboard I would appreciate the help.
