system when contacting Customer Support. You can also use these tools to:

■ Change factory default settings and to set or change the system configuration, which may be

necessary when you add or remove hardware.

■ Determine if all of the devices installed on the computer are recognized by the system and

are functioning properly.

■ Determine information about the operating environment of the computer.

■ Solve system configuration errors detected but not automatically fixed during the Power-On

Self-Test (POST).

■ Establish and manage passwords and other security features.

■ Establish and manage energy-saving timeouts.

All features identified in this chapter may not be available on all HP products.

2.1 Power-On Self-Test (POST)

POST is a series of diagnostic tests that runs automatically when the system is turned on. POST

checks the following items to ensure that the computer system is functioning properly:

■ Keyboard

■ Memory modules

■ Diskette drives

■ All mass storage devices

■ Processors

■ Controllers

✎

If the Power-On Password is set, a text box password prompt appears on the screen while POST

is running. You must enter the password before continuing. Refer to Chapter 3,

Section 3.1,

“Initial Configuration and Deployment.” for information on setting, deleting, or bypassing the

password.

If POST finds an error in the system, an audible and/or visual message occurs. For POST error

messages and their solutions, refer to Appendix C, “POST Error Messages.”
