What this manual does not contain

[edit | edit source]

No schematics or component values, and no power supply verification procedure. The CRT discharge and safety instructions it refers to are in Apple's separate Bulletins/Safety section, which is not part of this file; see CRT Discharge Procedure. The J28 section says the All-in-One's supply differs from the desktop and minitower supplies but does not say which jumper position it needs. The overview gives the hard disk as 4 or 6 GB and the specifications chapter as 2 or 4 GB. The electrical specification reads "300 W maximum continuous, 200 W peak output". The video symptom charts pair cable P905 with P913, while the take-apart chapter lists P905 as the fan cable.
