Compaq Presario and CQ Desktop PCs - How Do I Find My Model Number?

This document pertains to Compaq desktop PCs.
Use this document to identify your Compaq Presario Desktop computer. If you have a Presario Notebook PC, see Compaq Presario Notebooks - Locating the Model and Serial Numbers.
 caution:
Installing incorrect drivers or following incorrect troubleshooting procedures could damage your computer. Many Compaq Presarios are identified on the front of the computer by a series number rather than the actual model number. For example, your Presario may be labeled with 5000 on the front of the case, but it is actually part of a 5000 series PC. The correct model number may be 5WV283. If you have a 4000, 5000, 6000, 7000, or 8000 series PC, verify that you know the correct model or product number before using support information from the Customer Care web site.
 note:
Some desktop computers are sold in a bundle with a monitor, scanner, and/or printer. The bundle of products is identified by a "-b" after the model name. To find information for the desktop computer inside the bundle, search for the model name without the “-b”. For example, to find information on the SR1913wm-b, search HP's Web site for SR1913wm. To find information about another product in the bundle, such as a printer, look for its model name on a label adhered to the body of the product.
For more information on a given step, click the heading or the accompanying plus (+) sign to expand the information.
