I am working on an HP Pavilion DV7-1245DX. I have pretty much repaired the laptop and it will boot up. The issue I am having is that I can only get an external monitor to work for the graphics. I have attempted the Fn+F4 combination as well as the windows key+'P' and neither will toggle the display to the laptop display. Also, I have replaced the display on the laptop with the same results. I checked the event viewer and receive this info: Source: AMDKDAG Event ID: 43038 Task catagory: DAL I have searched the Microsoft website and other websites for any information and have not been able to find anything. Any help would be greatly apprecieated.
