More Problem Solving Procedures
This section provides a more detailed approach to identifying a problem and locating its source.
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.
Preparing the System for Diagnostic Testing
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.
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:
q
Does the diskette drive activity light turn on briefly?
q If a second diskette drive is installed, does its activity light turn on briefly?
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.
