Why won't my laptop screen work? It is white with black across it with purple looking pixels surrounding the black. I have my laptop hooked up to a different screen with the HDMI cord. I just want my laptop screen to work- please help.

Either your hook -up is not compatible, which is probably the problem or your graphics chip is failing. Unhook it from the other screen and if the laptop screen works fine, then it's the hook-up with the other screen you are using. If it doesn't, you have a graphics chip problem. Kind of depends on how old the laptop is.
