Serial Number

Location

Each computer has a unique serial number, which is located on

the corner of the computer access panel and also on the rear

panel of the computer. You may need to have this number

available if contacting Compaq customer service.

Turning Off Your

Computer

To exit Windows and automatically turn off the computer, click

Start

Æ

Shut Down.

In Windows NT Workstation, the power button always

functions as an on/off switch. In Windows, 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. To reconfigure the power button to work as an on/off

switch instead, run Computer Setup. (See the

Software

Reference Guide

for instructions.)

PGRADING THE

C

OMPUTER

This chapter explains how to remove the computer access panel

and convert the desktop computer to a minitower or the

minitower computer to a desktop. It also explains how to install

the following optional upgrade and replacement equipment:

■

Additional memory

■

Expansion boards

■

Additional graphics memory

beginning these procedures, ensure that you are discharged of

static electricity by briefly touching a grounded metal object. Refer

to the

Safety, Care & Regulatory Information

guide.

3.

Open the computer by removing its access panel. Refer to

“Removing the Computer Access Panel” in this chapter for

instructions.

4. Install any optional equipment. For instructions, refer to the

applicable sections of this chapter and to the documentation

provided with the optional equipment.

5. Replace the computer access panel.

6. Reconnect the keyboard, monitor, and other external

equipment.

7. Turn on the monitor, computer, and any devices you want

System configuration is the process of specifying the devices

and programs that make up a computer system. When you add

or remove optional equipment, or add a second diskette drive,

you must reconfigure the computer to recognize these changes.

If you install a Plug and Play device, Windows automatically

recognizes the device and configures the computer. If you install

a non–Plug and Play device, or if the device is not automatically

detected after installation, you must reconfigure the computer

after completing installation of the hardware. Select the Add

New Hardware icon in the Control Panel and follow the

instructions on the screen.

To reconfigure the computer in Windows NT Workstation, use

the software utility provided with the newly installed hardware.
