9-1 The Trackball Removal
1. Remove the ball from the trackball recess and wash it in warm soapy water to
remove any dirt that may have adhered to the ball itself. Make sure the ball is
thoroughly dry before re-inserting.
2. Use a cotton swab soaked in industrial alcohol to clean the inside of the
trackball recess to remove any dust or fine particles that have entered the
trackball unit, and to clean the two rollers to ensure the roller surface is smooth.
3. Replace the ball in the trackball recess and twist the trackball holder back into
place.
Problem Solving
The WinBook was designed and manufactured according to very stringent quality
standards. As such, with careful use, there is no reason why it should malfunction. The
field of personal computing; however, includes such a diversity of software and
hardware combinations that problems will inevitably arise. It is important that you
understand how to differentiate between problems caused by hardware malfunction
and those that arise out of an incorrect setting or software configuration.
The ability to accurately pinpoint the source of problems will only come with
experience, but always adopt a methodical approach to trying to solve problems. If
nothing appears on your LCD display when you use a particular software, it does not
necessarily mean that the display is faulty, it may mean that the software is not
configured correctly for the display. If your mouse is not working it does not
necessarily mean that the mouse or serial interface is faulty. Maybe your software is
expecting to find the mouse on COM2 and you have connected it to COM1.
There are a million different scenarios most of which are beyond the scope of this
manual. In this chapter we mention only some of the more basic hardware problems
that are directly linked to the WinBook, and how to solve these problems.
