Follow these general troubleshooting steps if you encounter a no video issue:
1. Does the power LED stay on when the power button is first pressed?
o If yes, do you eventually hear a Windows start up sound? (If you do not, the system actually has a no no POST issue).
o If no, the issue needs to be treated as a power issue.
2. Is an external monitor available to single out the internal LCD as being the problem?
o If yes, attach the external monitor. (pressing Fn + F10 to cycle between video may be required)
If the external monitor shows video the driver/video card is likely not the problem. The system will likely need to be repaired for a possible LCD/LCD Cable issue.
o If no, or if no video is showing at all, the system will likely need to be repaired for a possible issue with the video card/motherboard.
