Step 22
¶
-
Lift the DC-In board out of the computer by pulling up and away from you.
-
If you don't have a 667 MHz computer, there is a fan in this location which makes it a bit difficult to remove the DC-In board.
-
If there is a fan present, rotate the DC-In board slightly clockwise before easing it out at a slight angle in order to clear the fan clamp on top of it.

Modem Filter Board
¶
-
Before continuing, place a soft cloth on your work surface to rest the computer on. Turn the G4 over and place it on the cloth.
-
Disconnect the four indicated connectors from the logic board.
-
The large multicolor cable may be difficult to free.
-
The top center cable may not need to be disconnected to remove the modem filter board. It connects to the logic board fan to its immediate left, which is attached to the logic board itself.
