Connections - Dell Dimension XPS 50 Reference Manual

4-2 Dell Dimension XPS Txxx and Txxxr Systems Reference and Troubleshooting Guide
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 hard-
ware product; such files contain information updating or supplementing 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 "Resolving Software and Hardware
Incompatibilities" in Chapter 5). Also make sure you changed the appropriate set-
tings in the system setup program for the system's new hardware configuration
(refer to Appendix B, "System Setup Program").
2. Perform the steps described in the next section, "Connections."
3. Check the items listed in "Environmental Factors" found later in this chapter.
4. For power problems, refer to "Power" found later in this chapter.
5. Perform the checks in "Boot Routine" found later in this chapter.
NOTE: The boot routine is the operating system's attempt to load its files into
memory from the boot-up sector on the hard-disk drive or bootable diskette.
6. If you hear a beep code or see a system message, refer to Appendix C, "Diag-
nostic Codes, Beep Codes, and System Messages."
7 . If appropriate, refer to the subsections found later in this chapter titled "Monitor,"
"Speakers," "Modem," and "Drives."
8. Verify that the settings in the system setup program match your computer's con-
figuration as explained in Appendix B, "System Setup Program."
9. Use the Dell Diagnostics to check your system (refer to "Running the Dell Diag-
nostics" found later in this chapter).
10. If the problem persists, refer to Chapter 7 , "Getting Help," for instructions on
obtaining technical assistance.
Improperly set switches and controls, loose cables, and improperly connected cables
are the most likely sources of problems for your computer system. A quick check of
all the switches, controls, and cable connections can easily solve these problems.
NOTE: See the "System Features" section of the Dell Dimension XPS Txxx and Txxxr
Systems Help for the location of your computer's external connectors and controls.
To check computer connections, perform the following steps:
1. Turn off the computer, the monitor, and all attached devices.
