    • Pull on outer latch.

    • Lower door until it is level with your work surface.

    • Before working on the computer make sure it is not plugged into a power supply, then touch a metal object. This discharges static electricity, which could damage the computer.

    Fino a li lo intuisce anche un bambino. Io volevo sapere come levare l'altro sportello senza rompere niente. Ma una vodtra risposta non la vedo.

    Just a Thank You note. What a great and absolutely clear guidance. Apart from a fairly current Windows/Linux set-up, I really like to work on my old Macintosh G4 running Mac OS 9.2.1 Your instructions just helped me to make that machine even more useful. And yes, I am using it for productive stuff. Thanks again and keep up the good work. Alex, Germany.

Had a nearby lightning strike, "scrammed" my Mac, but couldn't start it up afterwards. Google led me to the ifixit site ( where I should have gone first!) and your instructions got me going again. Granted, I had an identical, spare Macintosh so I was able to pull that power supply to replace the damaged one and not have to wait for a replacement, but your step-by-step made the swap fairly easy! Thank you! I am happy tonight!

Now to order the replacement.

Hello Bill, I was wondering what power supply did you order as a replacement. Getting an original would cost over $100 almost next to $200, so I want to make sure where else I can buy a good power supply. Thanks in advance.

ditto…. like Bill I had a faithful G4 i use to archive some old OS9 files that need specific software that never went to OS X and some very basic Apache web server stuff. Mostly sleeping it went pop one day, I had replaced it a few years previously after a pram issue with a clean SH unit which i just swopped drives over, so getting sleeping beauty down from attic, following instructions I removed the power pac and in 30 minus the dead mac was running again and archive is protected
