What it settles

• Some 3400 display cables worked loose from the logic board, leaving no picture or backlight; the cure is a brightness and speaker grill (922-2488) with a foam gasket over the connector (pp. 7-8).
• Shutdowns on battery when the machine is jostled are cured by a battery bay gasket, kit 076-0706 (pp. 8-9, 204-207).
• The backup battery is a 60 mAh rechargeable NiMH pack stuck to the underside of the brightness and speaker grill (pp. 41, 100).
• The main battery is lithium-ion with an optional NiMH pack; a 3400 battery fits a 5300 or 190 but is not charged there (pp. 23-25).
• There is no voltage test for the battery or the adapter; the battery is checked with its indicator lights (pp. 196-197).
• The clutch-screw test with a floppy disk, and the warning that the display cable tears if its screw hole is misaligned with the clutch (pp. 162-163).

What this manual does not contain

• No schematics, no component-level parts list and no capacitor values.
• Nothing on the PowerBook G3 Series (Wallstreet) and later models.
