Troubleshooting checklist

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.
Connections
Check that all power and signal cables are securely connected to the
correct port on the computer.
The keyboard and mouse are particularly easy to connect into the
wrong port. Although the connectors are identical, the keyboard will
not work if plugged into the mouse port, and vice versa.
The two serial ports also appear identical. If you have a problem
make sure that the cable is connected to the correct port.
Power
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.
Monitor
If there is no display check that the monitor is turned on, and the
brightness and contrast controls are not turned to minimum.
Expansion cards
If an expansion card does not work, check that all internal cables are
securely connected, that the card is configured correctly and does not
'conflict' with another card or motherboard component. Check also
that the software that controls or uses the card is correctly
configured. Check in the chapter 'Upgrading' for information on, for
example IRQs and in the Appendix C 'System BIOS and set-up'
whether your chosen settings are usable. Check also that the
resources used are registered in the BIOS.
