Apple PowerBook (2400c) - Manual (Page 94)

Trackpad
The pointer won’t move.
m A program may be doing some work. Wait a few moments and then
try again.
m A temporary software problem may have caused the computer to “freeze.”
See “The Computer Freezes or Displays a System Error Message” in the
section “Problems Working With Programs,” earlier in this chapter.
The pointer sticks or jumps when I use the trackpad.
m Make sure to use only one finger on the pad and that your finger is dry.
Keyboard
Typing on the keyboard produces nothing on the screen.
m Make 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.
m Open the Easy Access control panel and make sure Slow Keys is
turned off.
m Open 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.
m Open Key Caps in the Apple (K) menu. If any keys in the window are
darkened, keys may be stuck down on your keyboard.
