My Dell Latitude D820 has many problems.... The biggest one is that I came home from work to turn it on, and the screen is black... When it turns on, it is completely white. I am so upset! I just got this...
It sounds like either the lcd screen or video card inside the computer
is bad. To isolate the problem try connecting an external monitor to the
laptop. It can be any kind of monitor even the
fat crt monitors as long as it has a vga cable to connect to your
vga port. If the external monitor displays ok that proves your video
card is ok and your lcd screen is the problem. If the external monitor
displays the black or white screen like your lcd screen then your video
card inside the computer is bad. The video will
show on most systems when you reboot without you having to do anything.
systems will require you to hit the FN (Function key) + F1 thru F12.
down the FN key then hit the correct key for displaying on the monitor
F12). The correct key will normally have CRT/LCD on it or it will have
the icon of a display.
Some laptops and the ac adapter get very hot. If the laptop is not
shutting down, then it is not overheating, so don't worry about it. You
can buy a laptop cooling pad that has fans on it and it plugs into one
of the usb ports on the laptop. The laptop sits on it to keep cooler.
Your battery is probably dead so that is why you can only power it up
using the ac adapter power cord. Once the power cord is removed, the
laptop will turn off. Batteries only have a useful life, and after
that, they have to be replaced.
