Dell™ Latitude™ LS and Inspiron™ 2000 Fan Removal and Replacement

This document provides instructions for removing and replacing the fan in the Dell Latitude LS and Inspiron 2000 computers.

NOTE: To verify whether you need to replace the fan, look for a white dot in the upper

left corner of the fan. This white dot indicates that the fan does not need to be replaced.

NOTE: Dell recommends that only a technically knowledgeable person perform this

procedure.

When the display assembly is open nearly 180 degrees, use a book or something similar to support it. The angle of the display assembly with respect to the bottom case should never exceed 180 degrees.

Recommended Tools

The procedures in this document require the use of a small flat-blade screwdriver.
