9.2 Troubleshooting
This section explains the actions the user should take to fix common computer problems
caused by hardware or software errors.
Should a problem occur, the initial steps listed below should be followed before taking
further action:
• On the tablet PC, try to identify and isolate the component that is causing the problem.
• Ensure that all peripheral devices are switched on before switching on the tablet PC.
• In the event of problems with an external device, ensure that the cable connections are
correct and secure.
• Ensure that the correct configuration information is configured in the BIOS setup
program.

indicator lamps lit? Are there any beeping sounds? If the user wants to seek assistance,
detailed descriptions are helpful for service staff.
