Troubleshooting

Serial Port

The serial device (modem, printer) doesn’t output anything or is out-

putting garbled characters.

1. Make sure that the serial device’s power is turned on and that the device is

on-line.

2. Verify that the device is plugged into the correct serial port on the rear of the

computer.

3. Verify that the attached serial device works by attaching it to a serial port

that is working and congured correctly. If the serial device does not work,

either the cable or the serial device has a problem. If the serial device works,

the problem may be due to the onboard I/O or the address setting.

4. Make sure the COM settings and I/O address are congured correctly.

Keyboard

Nothing happens when a key on the keyboard was pressed.

1. Make sure the keyboard is properly connected.

2. Make sure there are no objects resting on the keyboard and that no keys are

pressed during the booting process.

System Board

1. Make sure the add-in card is seated securely in the expansion slot. If the

add-in card is loose, power off the system, re-install the card and power up

the system.

2. Check the jumper settings to ensure that the jumpers are properly set.

3. Verify that all memory modules are seated securely into the memory sockets.

4. Make sure the memory modules are in the correct locations.

5. If the board fails to function, place the board on a at surface and seat all

socketed components. Gently press each component into the socket.

6. If you made changes to the BIOS settings, re-enter setup and load the BIOS

defaults.
