My Powerbook G4 (original version from 2001) suffered a left-hinge failure simply by opening the case. There had been *no* physical trauma to the PB before this point. The hinge seized, causing the hinge casting to snap on either side of the actual hinge area, and the LCD display case bent closest to the hinge.
These hinges are a major weak link in the Powerbook G4's design, and can (and do) fail under normal use, necessitating an extremely expensive repair, considering the relatively low value of the part that actually breaks.
Hi, the same just happened to me too, and I've browsed through this forum while looking for a price for repair (to Dublin, Ireland!) from PBM. What did you do? What's the reasale value on a Tibook with a snapped hinge (LCD is fine, but some buckling of lid at affected hinge).
