MacBook Battery/Charger Screen Faults

Posted:

Hey guys,



When I used to plug in my charger for my MacBook from battery, it used to brighten the screen whilst the charger was plugged. And when I took the charger out, it used to dim the screen whilst battery was in use. However, now it doesn't do this.



Any ideas on how to resolve this?



Thanks in advance
