If you encounter a problem with the computer the following
sections suggest checks to make before you alert your dealer,
authorised maintainer or support organisation. The checks
listed cover the causes of common problems.
Check that all power and signal cables are securely
connected to the correct port on the computer.
The two serial ports appear identical. If you have a problem,
make sure that the cable is connected to the port you are
trying to use.
Check that the AC power supply is switched on, and that
the fuse in the AC plug (if any) has not blown. If the system
still does not seem to be getting power, obtain another
power cord from your supplier.
If there is no display check that the monitor is turned on,
and the brightness and contrast controls are not too low.
If an expansion card does not work, check that all internal
cables are securely connected, that the card is configured
correctly, that its use of system resources does not conflict
another card or motherboard component, and that legacy
resources (if it is an ISA card) are properly declared in the
BIOS setup utility.
Check also that the software which drives or uses the card is
correctly configured.
