Need immidiate assistance.

Thanks.

Computer Does Not Turn On Or Go Into Windows

No Video

If the power indications are normal but there is never any video seen on the computer's display during the startup process, this probably indicates a No Video issue.

If you have a desktop computer and the monitor has its own power supply, make sure the monitor has a power indicator showing that it is turned on.

To troubleshoot a No Video issue, click on the links below:

For a notebook, press and hold the Fn key and then press the power button. This starts the pre-boot testing and will launch ePSA. ePSA will test video with a series of patterns. If they look fine but you want to test more, you can respond to the video test with "N" and ePSA will then launch the LCD BIST test. If you have a no video issue, you can either run the Fn+Power to enter ePSA or D+Power to run the LCD BIST.
