Solving Hardware Installation Problems
You may need to reconfigure the computer when you add or remove hardware, such as an additional
drive or expansion card. If you install a plug and play device, the Windows operating system
automatically recognizes the device and configures the computer. If you install a non–plug and play
device, you must reconfigure the computer after completing installation of the new hardware. In the
Windows operating system, use the
Add Hardware Wizard
and follow the instructions that appear
on the screen.
WARNING!
When the computer is plugged into an AC power source, voltage is always applied
to the system board. To reduce the risk of personal injury from electrical shock, rotating fans, and/
or hot surfaces, be sure to disconnect the power cord from the wall outlet and allow the internal
system components to cool before touching.
Look for the LED on the system board. If the LED is illuminated, the system still has power. Power
off the computer and remove the power cord before proceeding.
A new device is not recognized as part of the system.
Cause
Solution
Device is not seated or connected properly.
Ensure that the device is properly and securely connected and
that pins in the connector are not bent down.
Cable(s) of new external device are loose or power cables are
unplugged.
Ensure that all cables are properly and securely connected and
that pins in the cable or connector are not bent down.
Power switch of new external device is not turned on.
Turn off the computer, turn on the external device, then turn on
the computer to integrate the device with the computer system.
When the system advised you of changes to the configuration,
you did not accept them.
Reboot the computer and follow the instructions for accepting
the changes.
A plug and play board may not automatically configure when
added if the default configuration conflicts with other devices.
Use Windows Device Manager to deselect the automatic
settings for the board and choose a basic configuration that
does not cause a resource conflict. You can also use Computer
Setup to reconfigure or disable devices to resolve the resource
conflict.
USB ports on the computer are disabled in Computer Setup.
Enter Computer Setup (F10) and enable the USB ports.
Computer will not start.
