i recently noticed that my charger does not always charge. sometimes the screen dims out and the battery stops charging. if i wait a while then it charges again. could this be something regarding the charger? or a problem after the battery update?
Have you installed the battery update from the software updates? Have you calibrated your battery? To do that you let your battery, from a full charge, run out all the way until your computer goes to sleep and then you charge it back to full.
