User's Manual

 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.

 Some software programs, which have not gone through rigorous coding and testing, may

cause problems during your routine use. Consult the software vendor for problem solving.

devices powered up and connected first.

 Be sure to go to BIOS SETUP and load DEFAULT SETTING after BIOS re-flash.

otherwise the quick keys will not work.
