2.
If nothing happens when you type on the keyboard, see
“The Computer Locks Up,” earlier in this appendix.
3.
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.
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.
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 a few seconds to see if the screen displays any
text.
3.
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.
4.
If you still do not see anything on the screen, make sure
your monitor is connected to the computer properly. See
“Connecting a Monitor” in Chapter 1 for more details. Also
check the monitor manual for instructions on how to
connect it to the computer.
