Your computer has been fully tested and complies with the system specifications before
shipping. However, incorrect operations and/or mishandling may cause problems.
This chapter provides a reference for identifying and correcting common hardware and
software problems that you may encounter.
When you encounter a problem, you should first try to go through the recommendations in
this chapter. Instead of returning the computer and waiting for repair, you may easily solve
the problems by considering the following scenarios and possible solutions. If the error
continues, contact your reseller for service information.
Before taking further actions, consider the following suggestions:
 Check to see if the problem persists when all the external devices are removed.
 Check to see that the green light indicator on the AC adapter is lit.
 Check to see the power cord is properly plugged to the wall outlet and to the computer.
 Check to see the power indicator of the computer is on.
 Check to see if your keyboard is operational by pressing and holding any key.
 Check for any incorrect or loose cable connections. Make sure the latches on the connectors
latch securely on to the receptor end.
 Be sure you have not performed an incorrect setting on the hardware devices in the BIOS
Setup utility. A faulty setting may cause the system to misbehave. If you are not sure of the
changes you made, try to restore all the settings to factory defaults.
 Be sure all the device drivers are installed properly. For example, without the audio driver
properly installed, the speakers and microphone will not work.
 If external devices such as USB camera, scanner, printer do not function correctly when
connected to the system, it is usually the device’s own problem. Consult the device’s
manufacturer first.
