problem and locate its source.
!
CAUTION
Turn off the system and any peripheral devices before you
disconnect peripheral cables from the system. Otherwise,
you can permanently damage the system or the peripheral
devices.
1. Turn off the system and any peripheral devices. Disconnect all external
peripherals from the system, except for the keyboard and the video
display.
2. Make sure the system is plugged into a properly grounded power outlet.
3. Make sure your keyboard and video display are correctly connected to
the system. Turn on the video display, and turn up its brightness and
contrast controls to at least two-thirds of the maximum (refer to the
documentation supplied with the video display).
4. If the operating system normally loads from the hard disk drive, make
sure there is no diskette in the diskette drive. If the operating system
normally loads from a diskette, insert the operating system diskette into
the drive.
5. Turn on the system. If the power indicator does not light, but the system
seems to be operating normally, the indicator is probably defective.
