APRICOT 340 OWNER’S HANDBOOK 8/1
8 TROUBLESHOOTING
This chapter offers advice if you suspect a fault with your computer.
If in doubt, turn off the computer and unplug all power cords before
consulting your supplier or an authorized maintainer.
This chapter is concerned only with problems caused by the
computer itself; remember that problems can also arise from other
sources such as your network cabling, operating system or
application software.
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 unit’s 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. 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.
4. If the replacement fuse blows, call an authorized maintainer.
If the replacement fuse does not blow, reconnect a peripheral
and turn it on. Repeat this step for each peripheral in turn.
