Typing on the keyboard produces nothing on the screen.
One of the following is probably the cause:
mYou haven’t selected any text or set the insertion point (i).
Make sure the program you want to type in is the active program. Then place the pointer (8) in the active window and click to set an insertion point (i) or drag to select text (if you want to replace the text with your typing).
mIf the computer beeps every time you press a key, Easy Access is probably turned on. Open the Extensions Manager control panel in the Control Panels folder in the Apple (K) menu. Click the checkmark next to Easy Access to remove the checkmark and to turn off Easy Access. Then restart your computer.
mThe keyboard is not connected properly.
Turn off the computer by pressing the standby power button (®) at the back of the computer. With the computer off, check that the keyboard cable is connected properly at both ends.
mSome system software features are turned on that affect the way the keyboard works.
Open Easy Access from the control panels listed under the Apple (K) menu and turn off Sticky Keys, Slow Keys, and Mouse Keys.
mThere is a software problem.
Restart your Macintosh. For instructions, see “Start Over by Restarting Your Computer” in the section “If You Have Trouble” earlier in this chapter.
Check the startup disk and application program you were using when the problem occurred. To check that the programs and the system extensions you’re using are compatible with the system software, restart while holding down the Shift key; this temporarily turns off all system extensions. If your computer works normally after you do this, use the Extensions Manager control panel to turn on extensions and control panels one at a time. Restart after you turn on each extension. This procedure should identify incompatible extensions and control panels that may be causing the problem. (If you just added new software to your computer, its system extension is the most probable cause of the problem.) For detailed instructions, see the information about managing system extensions in the “Customizing Your Computer” topic of Macintosh Guide, available in the Guide (h) menu.
