This chapter guides you through some initial checks and procedures that can solve
basic computer problems. It also provides detailed troubleshooting information and
procedures to solve more complex problems. Complete the checks in this chapter
before you call Dell for technical assistance; even if these checks do not provide an
immediate solution, they can help technicians help you diagnose and fix the problem.

To perform an initial check of your computer, perform the following steps.
NOTE: If your computer is wet or damaged, refer to “If Your Computer Gets Wet” or
“If Your Computer is Dropped or Damaged” found later in this chapter.
1. If the problem you are experiencing began after making a change to your
computer, such as installing new hardware or software, undo the change if
possible.
If the problem is resolved, check any documentation that came with the option
you attempted to install or that describes the change you made. In particular,
read any text files (such as
readme.txt
) included with the software package or
hardware product; such files contain information that updates or supplements
the documentation for the software or hardware. Typically, readme files provide
installation information, describe new product enhancements or corrections that
have not yet been documented, and list known problems.
If you were trying to install new hardware, double-check configuration settings
and available system resources. Refer to the documentation that accompanied
the hardware device for more information. Also make sure you changed the
appropriate settings in the system setup program for the system’s new hardware
configuration (refer to Appendix B, “Using the System Setup Program”).
If you need technical assistance, contact the product manufacturer or the
company from whom you purchased the product.
