Hardware Diagnostic Testing; Verifying Proper Operation Of Key System Lights; Confirming Loading Of The Operating System - Intel S3420GP Manual

Hardware Diagnostic Testing

This section provides a more detailed approach to identifying a hardware problem and
locating its source.
Caution: Turn off devices before disconnecting cables: Before disconnecting any peripheral cables
from the system, turn off the system and any external peripheral devices. Failure to do so
can cause permanent damage to the system and/or the peripheral devices.
1. Turn off the system and all external peripheral devices. Disconnect each device
from the system, except for the keyboard and the video monitor.
2. Make sure the system power cord is plugged into a properly grounded AC outlet.
3. Make sure your video display monitor and keyboard are correctly connected to the
system. Turn on the video monitor. Set its brightness and contrast controls to at
least two thirds of their maximum ranges (refer to the documentation supplied with
your video display monitor).
4. If the operating system normally loads from the hard disk drive, make sure there is
no diskette in drive A and no CD-ROM disk in the CD-ROM drive.
5. If the power LED does light, attempt to boot from a floppy diskette or from a CD-
ROM disk.
6. Turn on the system. If the power LED does not light, see
Light".

Verifying Proper Operation of Key System Lights

As POST determines the system configuration, it tests for the presence of each mass
storage device installed in the system. As each device is checked, its activity light should
turn on briefly. Check for the following:
•
Does the diskette drive activity light turn on briefly? If not, see
Light Does Not
•
If system LEDs are illuminated, see
CD-ROM to be the first bootable device."
take to correct the problem.

Confirming Loading of the Operating System

Once the system boots up, the operating system prompt displays on the screen. The
prompt varies according to the operating system. If the operating system prompt does not
display, see
