Chapter 6: Testing and Troubleshooting
The purpose of this chapter is to provide a systematic method of isolating problems you may
have with the ACY25 series Notebook Computer. We assume that you have a basic
understanding of DOS-based computer systems as well as knowledge of standard
trouble-shooting procedures. This manual is written under the assumption that the problems
are indeed related with Notebook itself. The improper usage and application software
problems are excluded in this chapter. The system BIOS Beep Code is an integrated unit to
detect some errors in the system board. This beep code will give immediate identification of
certain system board problems. If the troubleshooting procedure is followed step by step, it
can efficiently isolate the problem and the problem can be solved easily.
PERFORM VISUAL INSPECTION

Power cords are properly connected and secured
Power supply is adequate for operation
There are no obvious shorts or opens
There are no obviously burned or heated components
All components appear normal
Troubleshooting Flowchart
Use the flowchart in Figure 6-1 as a guide for determining which troubleshooting procedures
to execute. Before going through the flowchart steps, verify the following:
• Ask the user if a password is registered and, if it is, ask him or her to enter the
password.
• Verify with the customer that Windows XP is installed on the hard disk. Operating
systems that were not preinstalled by Compal can cause the computer to malfunction.
• Make sure all optional equipment is removed from the computer.
• Make sure the floppy disk drive is empty.
