Troubleshooting
Hard Drive
Hard disk failure.
1. Make sure the correct drive type for the hard disk drive has been entered in
the BIOS.
2. If the system is configured with two hard drives, make sure the bootable
(first) hard drive is configured as Master and the second hard drive is config -
ured as Slave. The master hard drive must have an active/bootable partition.
Excessively long formatting period.
If your hard drive takes an excessively long period of time to format, it is likely a
cable connection problem. However, if your hard drive has a large capacity, it will
take a longer time to format.
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 configured 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 configured 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.
