Hi there. I've been having this very odd problem with my Dell Latitude E6430: Whenever I unplug the power cord from the computer, the display just turns white, blank. But when I plug it back in, the display goes back to normal. Before this, though, my screen was white even when the power cord was plugged in; however, I "fixed" it by unplugging/plugging back in the LCD cable on the display, which led to this issue. What could be the problem here? I've opened up the laptop and unplugged/plugged in the DC jack on the motherboard to see if that was the case, but that didn't do anything. Anything else I could do? Thanks a lot.
EDIT: The computer works fine with an external display, no hiccups with/without the power plugged in. Also, for some strange reason, after plugging in the HDMI cable for the display, then unplugging the power cord and then the HDMI, the display works without power cord for a bit before flickering back to white.
