Chapter 2: Utilities
Overview
The Notebook Computer has several built-in software utilities to help you get the most
from the system hardware. This chapter discusses:
: Power-On-Self-Test (POST).
: The System Configuration Utility (SCU).
Power On Self Test (POST)
The BIOS performs a series of power-on-self-test (POST) to diagnose hardware errors
when the system first starts up. During the POST procedure, the POST verifies that the
hardware is installed and operational. If a hardware problem exists, the POST routine
may halt execution (depending upon the severity of the problem).
