Preliminary Checklist
Here are helpful hints to follow before you take further actions when you
encounter any problem:
 Try to isolate which part of the computer is causing the problem.
 Make sure that you turn on all peripheral devices before turning on the
computer.
 If an external device has a problem, make sure that the cable connections are
correct and secure.
 Make sure that the configuration information is properly set in the BIOS Setup
program.
 Make sure that all the device drivers are correctly installed.
 Make notes of your observations. Are there any messages on the screen? Do
any indicators light? Do you hear any beeps? Detailed descriptions are useful
to the service personnel when you need to consult one for assistance.
If any problem persists after you follow the instructions in this chapter, contact an
authorized dealer for help.
