About 6 months ago, my regular Apple "T" charger started shorting out and dying, so I decided to replace it. Of course, seeing as how apples chargers wore out quickly on me, I decided to go the cheap route and get a $30 "L" charger from eBay. Lately I've noticed that when charging the computer, the L end of it gets extremely hot. Like hot enough to burn if touched. The area around my magsafe also gets quite hot, but around 20-30 degrees less than the charger I would guess. But it is pretty cold when the laptop is fully charged... So after seeing so many reports about people with non apple chargers, should I be worried about this? My magsafe is a bit dirty too, should I try cleaning it out?
