1-Now I bought an ASUS A43S. I5, 8gb RAM, 640gb HDD, 2GB Graphics Radeon (screw Nvidia), and 3 USB 3.0 ports. Affordable and satisfied. Screw Dell.
2-I do not know what happened to the XPS M1530 of mine now. Forget it. Life goes on.
3-I keep warning my family, relatives and friends about the intentional hidden problems of Dell's laptop. I did my part.
4-I have to admit nothing is perfect but Dell for sure is rubbish.
5-Do you want to experience of having to replace 2 or 3 motherboards for the same laptop due to the same root problem? Not in a right mind.
