Removing the Release Latch Assembly
To remove either the battery pack or hard drive release latch assembly,
complete the following steps:
1. If you are removing the hard drive release latch assembly, remove the
hard drive (Section 4.12).
2. Remove the keyboard cover (Section 4.7).
3. Remove the keyboard (Section 4.10).
4. Remove the latch spring [1] by holding it with needle-nosed pliers near
its wide end and pulling it straight up out of its slot (Figure 4-57).
5. Remove the e-clip [2] that holds the...](http://img.usermanuals.tech/thumb/1258/38935/w64_compaq-lte-elite-166.png "Page 167

Replacing the Release Latch Assembly
IMPORTANT: The parts for the battery release latch and hard drive release
latch assemblies are similar in appearance. However, note that
the battery latch is color-coded white, and the hard drive latch
is color-coded black. Be sure to use the correct set of parts
for this procedure.
To replace the release latch assembly, complete the following steps:
1. Replace the release button [1] (Figure 4-58).
2. Replace the latch [2] by sliding the latch onto its post (Figure...](http://img.usermanuals.tech/thumb/1258/38935/w64_compaq-lte-elite-167.png "Page 168

Chapter 6 - Compaq SmartStation Product Overview Introduction This chapter is an overview of the Compaq SmartStation and covers the following topics: o Serial number o System overview o Features o External switches, sensors, and LEDs o Connectors o Functional descriptions o Running Computer Setup o Power management o Security 6.1 Serial Number The serial number for the Compaq SmartStation should be provided to Compaq whenever requesting information or ordering spare parts. The serial number
for the Compaq SmartStation appears on a label near the connectors on the rear or side of the unit. 6.2 System Overview An automatic docking mechanism in the Compaq SmartStation docks the Compaq LTE Elite Family of Personal Computers (Figure 6-1) or the Compaq LTE Lite Family of Personal Computers (Figure 6-2). A Compaq LTE Lite must have a SmartStation Adapter connected to it before it can dock. Refer to Appendix D, Docking and Undocking, for more information on using the SmartStation Adapter. NOTE: Early model Compaq LTE Personal Computers (not Compaq LTE Lite models) such as the Compaq LTE 386s/20 cannot dock in the Compaq SmartStation. When the computer is docked, the 198-pin external options connector handles the entire electrical interface (both power and signal connections) between the computer and the expansion base. The expansion base provides the computer with two drive bays, two expansion board slots, built-in network capability, pass-through connections for external equipment, a battery charger for a Compaq LTE Elite spare battery pack, and other features. Refer to Section 6.3 for a list of the expansion base features.
