Preparing The Computer; Accessing The Configuration And Diagnostics Menu; Accessing The Configuration And Diagnostics Menu At Startup - Compaq DESKPRO 2000 SERIES Maintenance & Service Manual

2.3.1 Preparing the Computer

If you encounter an error condition, complete the following steps before starting problem isolation
procedures:
1. Ensure proper ventilation. The computer should have a 3-inch (7.6-cm) clearance
at the back of the system unit.
2. Turn off the computer and peripheral devices.
CAUTION: Always ensure that the power is off before disconnecting or reconnecting
the mouse, keyboard, or any other peripheral devices. Disconnecting or connecting any
peripheral devices while the unit power is on can damage the system board.
3. Disconnect any peripheral devices other than the monitor and keyboard. Do not disconnect the
printer if you want to test it or use it to log error messages.
4. Install loop-back and terminating plugs for complete testing.
5. Run the Configuration and Diagnostics utilities.

2.3.2 Accessing the Configuration and Diagnostics Menu

You can access the Configuration and Diagnostics utilities at startup from the hard drive or from the
diskettes. Procedures for both methods are presented below. Both procedures display the Configuration
and Diagnostics menu. Your particular menu may differ slightly from the one shown in Figure 2-2.
Accessing the Configuration and Diagnostics
Menu at Startup
To display the menu immediately after startup, complete the following steps:
1. Turn on or restart the computer. If Windows 3.1 or Windows NT is running, exit Windows and press
Ctrl+Alt+Delete. If Windows 95 is running, select Start, Shut Down, Restart the computer.
Immediately after the computer completes Power-On Self-Test (POST), which is indicated on the

of the screen.
The memory check only occurs on a cold boot.
2. Press F10 as soon as the cursor moves to the upper-right corner of the screen.
