PowerBook G4: Battery Fails to Charge

If you have a titanium PowerBook G4 with a round "puck" adapter, the battery will not charge unless the AC adapter is correctly inserted. It's possible to insert the adapter in such a way that it gets caught on the hinge and won't charge the battery.

(If you aren't sure which power adapter you have, click here for an article that shows pictures of each style. This article only applies to the round silver adapters. For help troubleshooting white "brick" style adapters, click here.)

Pay special attention when you insert the PowerBook G4 computer's AC adapter plug. When you insert the plug, make sure its nub (used to secure the plug to the circular AC Adapter) is in a horizontal position and not in a vertical position.

When you insert the plug you may feel some resistance as if the plug can go no further, but the metal part of the plug may not be fully inserted. The pictures below show an incompletely inserted plug and a properly inserted plug.

	WRONG - not inserted far enough into socket
	RIGHT - plug fully inserted

Press in until all of the metal on the tip of the plug is in the socket, as shown above.
