So, I got my first Macbook earlier this month (white 13" Macbook) and everything has been going well... Until recently, I plugged in the charger and nothing happened; the led light didn't light up and there was no sign of charging with the battery icon. I unplugged and then replugged multiple times, and tried different outlets to no avail. I couldn't test on other computers or with other chargers to confirm which end the problem was coming from, so I just gave up for a while, and then put the computer to sleep. While it was sleeping, I plugged the charger in once more, and then the led light lit up and I opened the computer to see that the battery was finally charging. FWIW, the computer's battery was at about 8% or so prior to being put to sleep. My question is, should I still be worried? Is there an explanation for why the charger would randomly stop working and then start again based on the events described?
