Problems when starting

If you suspect a blown fuse


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 and connectors inside the computer when fitting
expansion cards, or upgrading the motherboard, or indeed anything
that may require temporary removal of the system cover.
If in doubt
If in doubt
Turn off the computer and unplug the power cord before consulting
your supplier or maintenance provider. Make a note of any of the
symptoms, error codes, display messages etc., before calling.
In the United Kingdom, and some other countries, AC plugs
contain fuses. Your Apricot computer is initially supplied and fitted
with the correct fuse for operation in the country in which it is sold.
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:
Turn off the computer and unplug all power cords.
Unplug all peripherals.
Try to discover the cause of the fault. If none is apparent,
replace the blown fuse with one of the same rating, reconnect
the system unit power cord and try to turn it on again.
If the replacement fuse blows, call your supplier or
maintenance provider.
If the replacement fuse does not blow, reconnect one
peripheral at a time and switch it on. Repeat this step for each
peripheral in turn.
