The family computer (iBook G3 700MHz/384/20/10.3) Has developed a problem, where any pressure on the underside of the left palm rest makes the computer immediately shut off. I originally thought it was the typical graphics issue that iBooks suffer, but for it to completely just cut out is a little strange... Anyone else have similar experiences? Anyone know how to remedy the situation? I was hoping something simple would fix this, but it seems a shim would only worsen things as pressure kills the iBook immediately!! Help!
