Troubleshooting
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 white light indicator on the AC adapter is it.
• 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.
