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
Keyboard and Speaker Options” in Chapter 2.
3. If nothing happens when you type on the keyboard, see
“The Computer Does Not Respond,” above.
Monitor Problems
For monitor problems, check the following:
1. If there is no display on the screen, check that the monitor’s
power switch is on and that the power light on the monitor
is lit. If the power light is on but you still do not see
anything on the screen, check the monitor’s brightness and
contrast controls.
2. Did you run the SNOOZE utility? Your screen may be just
temporarily blank. Press any key to display the current image
(or activity). If you still see nothing, see the instructions for
using the SNOOZE program in Appendix A.
3. If the power switch is on but the power light is not, turn off
the monitor’s power, wait five seconds, and turn the power
back on. Wait to see if the screen displays any text.
4. If the monitor’s power light still does not come on, check
the electrical outlet for power. Turn off your monitor and
unplug it from the wall outlet. Plug a lamp into the wall
outlet and turn it on to see if the outlet supplies power.
