I replaced the internal battery for the Dell Latitude E5570. The laptop was fine all throughout the charge and removal of the plug for 4 enjoyable hours of battery life until bed. However, today the screen flickers like either the cable is loose from me poking around and replacing the battery or the screen is about to go. Just thinking I type, I'm going to run a hardware dignostics on the video but what could have I have possibly loosen up to create the flicker. PS. It seems as if it's not a loose cable and the screen is in fact going out. The screen is no longer flickering. Actually, it flickers when I execute applications, minimize/maximaize things but not when typing. Basically, thing get flicker crazy when the mouse is involved. I see this getting worse through time. Thoughts?
