I was laying with my iBook 1.42 GHz, 14", watching YouTube and talking on iChat. While doing this, my computer shut off. This was happening every so often, and every time it did, I had to hold the power button for a few seconds, then turn it off. After it started to boot, I wanted to get a snack. I put the laptop on the bed (it was on my lap), and started to get up. To my surprise, my charger sparked and smoke came out. I went and unplugged it. This charger isnt that old, about 2 months. Would Apple replace it for free? Any other comments? Here are some pics of the damage. The black part is burned.
