If the keyboard and the RAM cover was removed, this would be the issue. The plate above the CPU is the primary heat collector for the CPU, which is then conducted away from the CPU by the big pipe to the rest of the heatsink which (iirc, and looking at the thing from the normal persepctive) is off to the left of the cpu near the edge of the case. See: <http://s1.guide-images.ifixit.com/igi/BstZaZL2ZCaSSDH1.large> It's normal for that plate to get quite hot; normally you don't notice this because the heat shield over the RAM and CPU, as well as the keyboard is between you and the heat sink. <http://www.ifixit.com/Guide/Repair/PowerBook-G3-Pismo-Heat-Shield/19/1> -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs --~--~---------~--~----~------------~-------~--~----~ You received this message because you are a member of G-Books, a group for those using G3 iBooks and PowerBooks (we run a separate list for G4 'Books).
