HP 250 - Chapter 10: In Case of Difficulty

~----_1O_
In Case of Difficulty
In the event that your system becomes inoperable, you should take
action to pinpoint the problem. By checking the system yourself,
you may be able to avoid calling for service. In any case, you
can minimize the time needed to get your system back into
operation.
When you get an error, you should do things the SLOW way:
Stop what you are doing
Look up error message or procedure described in this manual
Observe what is on the screen
Write down this very important information.
Generally, any difficulty you encounter falls into 1 of 2
categories •
•
Start-up errors
• Processing Errors
One classic symptom of a start-up error is that the cursor does
not appear on the screen. (Although this is not always true).
Processing errors can be caused as a result of hardware failures,
software errors, or operator errors. They may result in a loss
of the cursor and program control. They also may result in an
inability to access certain data, print reports or plot charts.
