Use the controls on the monitor to turn up the brightness and contrast.
Remove any diskettes, then turn off the power switches on the monitor
and the main unit. Check that the monitor’s power cable is securely
connected to the electrical outlet and that the monitor cable is properly
connected to both the monitor and the main unit. Turn both power
switches back on.
Turn off the power switches on both the main unit and the monitor.
Then check the electrical outlet for power. Plug a portable lamp into the
outlet you are using for the monitor and turn it on to see if the outlet
supplies power.
The Computer Does Not Respond
If the computer does not respond to something you enter from the key-
board, try the following:
1.
Wait a few seconds. Some operations take longer to perform than oth-
ers. For example, a spreadsheet program takes longer to recalculate an
entire spreadsheet than to record one figure. Also, BASIC programs
that have a lot of calculations to perform can take several minutes, or
even hours. Be aware of the task the computer is performing and judge
the time accordingly
2.
If the computer remains locked up, follow the steps in Chapter 2 under
“Resetting the Computer.”
Floppy Disk Problems
If you have trouble with a diskette, check the following questions:
1.
Is the diskette damaged? Copy the diskette and repeat the operation that
caused the problem using the copy. (If you have trouble copying the
entire diskette, some of the sectors may be bad. Try to copy single files
with the COPY command.) If the operation works using the copy, the
original diskette is probably damaged. Make another copy to use as a
backup.
