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. 
Legacy peripheral are not plug-and-play capable. You need to 
restart the system with these devices powered up and 
connected first. 
Be sure to go to BIOS SETUP and load DEFAULT SETTING 
after BIOS re-flash. 
Be sure the Quick Key Lockout Switch on the bottom of the 
computer is not engaged; otherwise the quick keys will not 
work.
