|I have a Dell Latitude D620 laptop that have display problem. I am sure the LCD, invert and cable are good since I have token them off and tested on another laptop and they worked fine.|
The problem is
1. The LCD is totally dark, no any sign.
2. When an external monitor connected, it takes more time to boot to the system, and the usually display of DELL … and windows loading status bar are not show up. When external monitor light is on, the Windows is already started. i.e. you will not see the windows loading procedures as we usually see.
3. When I disconnected the internal LCD connection cable, the boot is fast and the initially boot dialog of DELL… and windows loading status bar all show up, which means very normal. But as I said before, I have tested the LCD, inverter, and cable on another laptop and they are all worked fine and I also used another laptop’s LCD, invert and cable on this laptop, and got same problem. So it’s not LCD problem, but why?
Anyone have similar problem and how to fix?
