Hardware diagnostic testing

This section provides a more detailed approach to identifying a
hardware problem and locating its source.
Caution:
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 (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 floppy disk 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 disk 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 85.
Turn off devices before disconnecting cables. Before
