Hello! I am fortunate enough to hold a PowerBook in my hands! The condition is surprisingly good for old age. Some Scratches on the Case an one on the Screen, but anyways: its an 15" G4 DLSD /HR-AI :-D :-D. On occasion, the hard drive of 80GB is exchanged for a larger one. What makes me wonder are the differences in temperature for the GPU? istats varies between 88 ° C and 98 ° C. g4fan but indicates "normal" temperatures? Only a short moment when starting the program, it shows absurd data like 225 ° C .. The fans are running normally. The thermal paste I wanted to renew anyway ... Could this possibly be due to defective sensors? Furthermore, I noticed that when the PowerBook goes into standby, the Powercord LED changes from green to orange and then back to green for a fraction of a second ... I do not know that from my old powerbook. The PRAM battery has been renewed by the previous owner. See defective, broken screw! :-( Maybe someone has an idea? My macbook Air 1th gene will first dust up unused ;-)! Is much louder anyway and I can now use PPC programs on original hardware. Thank you all in advance for your support.
