I have another question about my laptop and it's yet again something I have no knowledge on.
Usually, when the charger for your laptop is plugged in, the screen is brighter. When you unplug, the screen goes dimmer. This is what I have been used to.
Now, for some reason, it appears to be the other way around. I don't know if I accidentally changed it some how but I have no idea how to change it back. Does anyone know how?
