I am 99% sure this is video adapter related but i wanted to post here just to get a little input from the community.
Dell e1705 uses ATI 1400 Mobility module/adapter
the video will come up on the LCD occasionally hitting the FUNC crt/lcd with an external vga monitor attached, the external will have vertical bars of static periodically and then it will clear up and windows gui will appear, if i reboot, and hit the func crt/lcd couple of times, the LCD on the laptop will boot from pst and go to windows without problem, about half the time it will remain dark.
replace the video adapter?
300.00 + dollars for a refurbished one...hence the post just to cover my bases.
