What to do if the system doesn’t work

This section describes basic problems and the remedies that can be used if the

system does not seem to work correctly. Most problems can be sorted out very

quickly once the root cause is established.

Before seeking assistance, have a look at these common problems and their

possible solutions.

Try, wherever possible to isolate the problem by trying out a replacement device (i.e.

mouse, keyboard etc.) if one is at hand. This will help you identify the item that is

causing the problem and make it easier for the problem to be efficiently dealt with.

Note: Please don’t remove the system unit cover: This action should only be

performed by a qualified engineer, as you risk injury by hazardous voltages.
