I have an old laptop that seems to be dying. The system was saying the battery only had 20% capacity which was not an issue because I normally run on mains anyway. Then the battery dropped to 16% and the screen has started to sort of flicker. I can still run the laptop but it is not really usable.Maybe the battery issue is causing the screen issue? The problem is I don't want to go the hassle/cost of replacing the battery only to find that the screen is still shot.
Does the screen still flicker if you run the laptop on the charger with the battery removed? If it does, the fault is not because of the battery.
