PROBLEM SOLVING SX/DX
The 486SX/DX-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

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
486SX/DX-WinBook, and how to solve these problems.

POWER PROBLEMS
I can boot up the computer but cannot run my software as the screen freezes.
This may occur infrequently when running the 486SX/DX-WinBook from the battery and when the
battery is very low. Connect the AC adapter and recharge the battery. Remember that you can still use
the WinBook while the battery is charging.

Nothing happens when I turn on the power switch.
If running from the power adapter, check that the adapter is correctly plugged into both the AC outlet
and the 486SX/DX-WinBook, and that there is power in the power outlet. The power LED on the power
adapter should be on. When running on the battery, check that the battery is correctly installed. Check
also that the battery is not totally discharged. If it is, recharge it by connecting the power adapter to the
system.

BOOT UP PROBLEMS
The power is reaching my 486SX/DX-WinBook but the system “hangs” before it is booted up.
Boot up problems are usually caused by an incorrect configuration or statement in the CONFIG.SYS file
(see your DOS user’s manual). To test whether this is the case, try booting up from a floppy diskette
[SX/DX 9-4] inserted in the A: drive (this diskette must be a bootable system diskette). If this works, edit
the CONFIG.SYS file on the hard disk drive and then try booting from the hard disk drive again.

DISPLAY PROBLEMS
I can see nothing on the LCD display even though my system appears to have booted up correctly.
