Reading the Self-Test

Computers can be valuable time-savers, but only if they are operating reliably. If a
problem goes undetected and your computer fails in the middle of a job, data can be lost
and hours of your labor may be wasted.

this way, most problems are caught before you start to work, sparing you the frustration
of a mid-session failure.
In this chapter, we describe how to interpret the self-test messages and suggest what you
should do in case of a failure.
