OWNER’S HANDBOOK 8/1
8 TROUBLESHOOTING
This chapter offers advice if you suspect a fault with your computer.
It is concerned mainly with problems caused by the computer itself;
problems more often arise from other sources such as your operating
system or application software.
It must also be remembered that it can be very easy to leave off or
dislodge cables inside the computer when fitting expansion cards, or
upgrading the motherboard, or indeed anything that requires
temporary removal of the system cover.
If you are apprehensive
Make a note of any of the symptoms, error codes, displayed messages and
so on, then turn off the computer and unplug all power cords before
consulting your supplier or maintenance provider.
Problems when starting
If you suspect a blown fuse
In the United Kingdom, and some other countries, AC plugs
contain fuses. If the fuse in the system’s unit AC plug blows when
you turn on the computer, this may be caused by an AC power
surge, but is more often a symptom of problems with the computer
or its peripherals. Follow these steps:
1. Turn off the computer and unplug all power cords.
2. Unplug all peripherals.
3. If you suspect the blown fuse is in the AC plug, replace it with
a fuse of the same type and rating which is BSI or ASTA
approved to BS1362. Always refit the fuse cover; never use the
plug with the fuse cover omitted.
4. If the replacement fuse blows, call your supplier or
maintenance provider.
If the replacement fuse does not blow, reconnect a peripheral
and turn it on. Repeat this step for each peripheral in turn.
