My 1.67ghz, 15" high resolution, Powerbook seems to be broken. I use my laptop all day every day on battery power, and charge it through the night. Today, when I got home, it drew no charge from the adaptor. I have a backup iBook G3 which still charges perfectly off the same adapter, yet the Powerbook doesn't. I have left plugged in for about 45 minutes now, but still no charge, so the computer won't start up. I have a lot of important work on this computer, so I at least need some way of getting my data off it without ripping it apart to remove the HD. What should I do? I suspect that the power port in the laptop is somehow deformed, and thus is not making a connection. If this is the poblem, will it mean a new logic board?? Thank you for reading.
