I dunno what's wrong with it, the power adapter or the actual laptop. The original adapter snapped so I got a MacAlly one, the reviews said it was low quality and stops working after a while, I got the problem, and I had to hold the charger at angles to get any charge. Today I got a new one, and the light in the battery doesn't blink at all, and with the new adapter, not the macally one doesn't charge either. My laptop won't turn on, and it's been charging all morning. I then tried it without the battery, still won't charge. I noticed the small bit the charger goes inside moves about, I dunno if that's the problem, other members of my family are convinced it's the £600 iBook that's ruined, but I have had it for a little under a year.
