  1. Raise the display so you can access the keyboard.
  2. Make sure the keyboard locking screw, located in the small plastic tab next to the Num Lock key, is not in the locked position. The iBook comes with the keyboard unlocked, so unless you or someone else locked the keyboard, you can skip this step.

To unlock the keyboard, turn the screw 1/2 turn.

Release the keyboard by pulling down on the keyboard release tabs (located to the left of the F1 and F12 keys), then lift the top portion of the keyboard up slightly, and toward the display.
