Troubleshooting Without Diagnostics
Preliminary Checklist
This section describes some simple, preliminary tests and guidelines for troubleshooting the
computer without using the diagnostics.
■
Are the computer and monitor connected to a working electrical outlet?
■
Is the voltage select switch is set to the appropriate voltage for your region (115V or 230V)?
■
Is the computer turned on?
■
Is the green power light illuminated?
■
Is the monitor turned on?
■
Is the green monitor light illuminated?
■
Turn up the monitor brightness and contrast controls if the monitor is dim.
■
If the system has multiple video sources (embedded, PCI, or AGP adapters) installed
(embedded video on select models only) and a single monitor, the monitor must be plugged
into the monitor connector on the source selected as the primary VGA adapter. During boot,
the other monitor connectors are disabled and if the monitor is connected into these ports, the
monitor will not function. You can select which source will be the default VGA source in
Computer (F10) Setup.
■
Press and hold any key. If the system beeps, then the keyboard is operating correctly.
■
Check all cables for loose or incorrect connections.
■
Reconfigure the computer after installing a non–Plug and Play expansion board or other
option, such as a diskette drive.
■
Are all of the necessary device drivers installed?
■
Have all printer drivers been installed for each application?
■
Remove all diskettes from the diskette drives before you turn on the system.
■
Are all switches set correctly?
■
Is the NIC Remote Wakeup cable (featured on some models) connected between the NIC and
the riser/system board?
