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. Except for the keyboard and
video monitor, disconnect each device from the system.
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 CD-ROM/DVD disk in the optical drive.
5. If the power LED does light, attempt to boot from a USB floppy or from a CD-
ROM disk.
6. Turn on the system. If the power LED does not light, see “Power Light Does Not
Light” on page 78 .
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 drive activity light turn on briefly? If not, see “Drive Activity Light Does
Not Light” on page 80 .
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 “No Characters Appear on Screen” on page 78 .
