If you are having trouble with the keyboard, check the following:
1.If the screen displays a keyboard error message when you turn on or reset the computer, make sure the keyboard is securely connected to the computer. 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 keys on the numeric keypad work only as numbers. If the Num Lock indicator in the upper right corner of the keyboard is lit, press [G] to turn off the function.
If you want to change the initial setting of the num lock function, see “Using the Keyboard and Speaker Options” in Chapter 2.
3.If nothing happens when you type on the keyboard, see “The Computer Does Not Respond,” above.
4.If you still have trouble with your keyboard, run the keyboard diagnostic tests described in Appendix C.
