Ÿ
3.5-in. diskette drive
Ÿ
Hard disk drive (some machines may have up to 4 hard disk drives

– Ensure all power cords and cables are connected properly.
– Ensure the monitor brightness and contrast controls are not turned down.
– Ensure the sound volume control is not turned down and the speakers are
powered on.
– Power on the system unit.
Note: Some monitors have a detachable system I/O signal cable
between the monitor and the system unit. In either case, check
the power cord or cable before replacing the unit. See
“Detachable Monitor I/O Signal Cable Connector Test Points” on
page 5-21 for pin identification.
High voltage Northern and Southern Hemisphere monitors may
come with a voltage selector (110 V–220 V) switch. The 145-W
power supply may have a voltage selector (110 V–220 V) switch.
Match the switch to the line voltage.
– Ensure the correct monitor frequency is set in the Setup Utility for the
monitor used with the system (see “Using the Setup Utility” on page 1-16).
If the monitor frequency is set incorrectly, the monitor may not be readable
in certain modes. To determine the correct monitor frequency, look on the
monitor for the part number, or see the product information shipped with
the monitor. Set the monitor frequency equal to or less than the monitor’s
maximum horizontal frequency (also known as the horizontal scan rate).
See “Refresh Rates and Monitor Frequencies” on page 1-12.
– Note any symptoms, messages, error codes, or beeps.
– Make sure there are no diskettes or CDs in the drives.
