If you are having trouble with the keyboard, check the following:
1.If the screen displays one of the following keyboard errors when you turn on or reset the computer, make sure the keyboard is securely connected to the computer:
301 KEYBOARD ERROR
303 KEYBOARD OR SYSTEM UNIT ERROR
304 KEYBOARD OR SYSTEM UNIT ERROR
See ‘Connecting the Keyboard” in Chapter 1 for instructions.
2.If the cursor keys do not work properly, the Num Lock function may be on. When Num Lock is on, the numeric/ arrow keys on the numeric keypad work only as numbers. Check to see if the Num Lock indicator in the upper right corner of the keyboard is lit; if it is, press the Num Lock key to turn off the function.
If you want to change the initial setting of the Num Lock function when you turn on the computer, see “Using the Speaker and Keyboard Options” in Chapter 2.
3.If nothing happens when you type on the keyboard, see “The Computer Does Not Respond,” above.
