The pointer sticks or jumps when you use the trackpad.

Keyboard
Typing on the keyboard produces nothing on the screen.
mMake sure the program you’re using is set to accept text input. Usually you need to set an insertion point or select some text before typing. If you’re using a communications program, you may need to turn on the “local echo” setting.
mOpen the Easy Access control panel and make sure Slow Keys is turned off.
mOpen Key Caps in the Apple (K) menu and check whether the computer is recognizing keyboard input. If so, the keys in the Key Caps window will indicate when keys are pressed on the keyboard.
A key won’t stop repeating.
Open Key Caps in the Apple (K) menu. If any keys in the window are darkened, keys may be stuck down on your keyboard.
PowerBook display
The screen went blank.
mScreen dimming may be on. Move the pointer to restore the screen’s brightness.
mThe computer may have gone to sleep. Press any key (except Caps Lock) on the keyboard to wake it.
mThe battery may need recharging. Plug in the power adapter, let the battery charge for a few minutes, and then try to wake or start up the computer again.
mIf an external monitor is connected, the image may be displayed on that monitor and not on the PowerBook’s display. (If the external monitor is set to a different resolution from the 800 x 600 pixels of the PowerBook display, the computer’s image only appears on the external monitor.)
