chapter 1
THE COMPUTER AT A GLANCE
The Compaq Deskpro EN Series, Small Form Factor and Net
PC models, is a line of full-featured PCs in a small, highly
integrated design offering leading manageability, serviceability,
and consistency. Each computer is designed for easy
deployment in small workspace environments. An optional
mounting bracket allows you to mount the computer on, under,
or adjacent to your work surface in a horizontal or vertical
orientation to save desk space. (See Chapter 3, “Upgrading the
Computer,” for more information on mounting.)
Your computer combines an Intel processor with a generous
hard drive and system memory of up to 256 megabytes (MB) of
standard synchronous dynamic random access memory
(SDRAM). In addition, special features include integrated AGP
graphics, integrated network interface, and integrated audio.
Upgrades are simple due to a slide-out system board and tool-
less removal of most internal components. This chapter
describes the features and components of your computer.

■ 512-kilobyte standard secondary (L2) cache on some
models

Turning Off Your
Computer
To exit Windows and automatically turn off the computer, click
Start, then click Shut Down.
In Windows NT Workstation 4.0, the power button always
functions as an on/off switch. In Windows 95, however,
pressing the power button does not turn off power altogether,
but instead causes the computer to enter a low-power standby.
This allows you to quickly power down without closing
applications and to quickly return to the same operational state
without any data loss. If you want to turn off power altogether,
hold the power button in for four seconds or more.
To reconfigure the power button to work as an instant on/off
switch instead, run Computer Setup. (See the Software
Reference Guide for instructions.)
