POST Message Charts
The computer might display more than one error message. Often, the first error to
occur causes subsequent errors. When using the POST message charts in this
section, always begin by following the suggested action for the first error message
that appears on your computer screen. Note that, in these charts, “X” can be any
alphanumeric character.
