I really appreciated this photo and text info page. My powerbook was making a grinding sound. When I opened it up it turned out to be the hard drive. I installed a solid state drive, but I am having issues installing the OS.
Some things I found that might be helpful to others....
1) I could never boot my powerbook to a CD by holding down the "C". Key. However I was able to boot many time by holding down the Option key.
2) I never did pull out the two cables in step 12 and 13. All I did was lift up the keyboard and lay it up next to the screen with out ever taking the two cable off the power book. I had more then enough room to pull the old hard drive and install the new one.
3) Try holding down the Option key on boot if you can not boot to a CD. It works for me.
Thank you who ever you are for posting this web page. It was extremely helpful.
I am interested in rebuilding older computers from the 1980s to maybe the mid to late 1990s. I am also interested in rebuilding and modifying Nokia N95 series cell phones.
