More Problem Solving Procedures
This section provides a more detailed approach to identifying a problem and locating its
source.
Preparing the System for Diagnostic Testing
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 all of them from the
system, except the keyboard and 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 (see 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. Otherwise, place a diskette containing the operating system files in
drive A.
5. Turn on the system. If the power LED does not light, see “Power Light Does Not Light”
on page 82.
6. If errors are encountered, power off the system and remove all add-in cards.
Monitoring POST
See “Power-On Self-Test (POST)” on page 41.
Verifying Proper Operation of Key System Lights
As POST determines the system configuration, it tests for the presence of each mass stor-
age device installed in the system. As each device is checked, its activity light should turn on
briefly. Check for the following:
q Does the diskette drive activity light turn on briefly? If not, see “Diskette Drive Activity
Light Does Not Light” on page 83.
q If a second diskette drive is installed, does its activity light turn on briefly? If not, see
“Diskette Drive Activity Light Does Not Light” on page 83.
Confirming Loading of the Operating System
Once the system boots up, the operating system prompt appears on the screen. The prompt
varies according to the operating system. If the operating system prompt does not appear,
see “Initial System Startup” on page 79.
