My Sister has just called to say her G3 800mhz ibook will not turn on. The battery is also flat and will not charge (she rarely uses it). My initial thought was a problem with the battery or power brick, however it will not boot with the battery out and the light on the power plug is glowing green all the time so I assume is has power to the plug end. Any other thoughts as she is talking or binning it and buying a reliable computer.
