Two weeks ago, I purchased my daughter a brand new 15" iBook. She had no trouble with it until about a week ago, when we had a severe wind storm with gusts up to about 60mph. All the lights were flickering on and off, and I decided to shut everything down. She was about to turn the iBook off when it just blinked out. Later, she tried to turn it back on and there was absolutely nothing. No disk sound, no lights, nothing.
I tried a number of things, but all with the same non-successful result. It was late, so I was going to call Apple in the morning, but then remembered something that I used to do with my old Power Tower Pro and power management. I unplugged the iBook, took out the battery out, and left it overnite. In the morning, after putting it back together, the iBook worked perfectly and has ever since.
I did recently get her a small APC battery backup that also has line conditioning, just in case...
