Introduction

This section explains the diagnostic aids that are available for troubleshooting problems on the system.

Power-On Self Test

Each time you power-on the system, the power-on self test (POST) is initiated. The POST takes up to 120 seconds to complete (with Power Management disabled or not installed), depending on the options installed.

The POST checks the following:

System board

Memory

VGA

Hard disk drive(s)

Diskette drive(s)

Keyboard

Mouse

Parallel port

Serial port(s)

CD/DVD-ROM drive

Sound adapter card

To start the POST, turn on the monitor and the system unit. The following happens:

1. The IBM APTIVA Logo appears on the monitor.

Pressing F1	at	this time causes the Setup Utility menu to appear after
the POST	has	completed.

2.A count of the system memory appears at the upper-left corner of the screen.

3.If an error is detected, an error code appears under the system memory count.

Note: A memory	error	can	appear without the memory count as:
XXXXXX XXXX		201,	where the first six Xs = memory address,
the next	four	Xs	= data.

4.Successful completion of POST is attained when there are no errors detected in the system.

5.If a critical error is encountered, the system halts.
