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
