Having problems with your Dell Latitude C640 Notebook ?

Strange video issue. help please.

\015 Hello to whom ever can help. i am the owner of a small pc repair shop and i have a snag. i have a dell lat.c640 and i am experiancing a strange video problem. the pc will not boot from system lcd it will only boot from external monitor. i have replaced lcd because it was cracked and also the video to try to resolve the issue. but the funny thing is ever once in awhile it will allow you to switch to the default system mon. i even tried a whole new screen and cable same results. bios says boot from dock screen so i changed it to default system mon but still same thing. i ordered the video card from ebay and am wondering if it could be faulty but this is what it was doing before i replaced it. any suggestion would be helpful. thank you.\015

Answers :

This sounds like a damaged motherboard. I would check with Dell's chat support, they can direct you to more troubleshooting resources and maybe even offer genuine repair parts. I have used them quite a bit, and if you can convince them you have an A+ cert, most of the time you can skip a lot of the BS steps that never work or do not help.
