i receive salvageable materials all the time, and about a month ago i got an old school desktop. Power Macintosh g3 - all in one. it doesn't boot up. i took it all apart, cleaned everything, went through the service manual, reset the cuda, bought a new 3.6v battery, used a different power cord.... im a handy guy, but im not too savvy with computers. i can use them, but im not educated on the hardware operations. i dont need a walkthrough or anything major, just some ideas on possible reasons for the malfunction. everything is in order according to the manual.
