Common problems
If you encounter a problem with the computer the
following sections suggest checks to make before you
alert your supplier, 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.
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 compuuter is not
in an energy-saving mode (see the
Welcome chapter),
that the monitor is turned on, and the brightness and
contrast controls are not too low.
If you have fitted a new video controller expansion
card and subsequently encounter problems try
disabling the on-board video controller by removing a
jumper from the motherboard. See the
Motherboard
Features & Upgrades chapter for more information.
Mouse
If the screen cursor moves jerkily, the ball inside the
mouse may require cleaning. Open the base of the
mouse can clean the ball in water mixed with a small
amount of mild detergent. Clean any grease and dust
from the rollers inside the mouse with a cotton swab
moistened with a solvent cleaner.
