Audio Problems; Hard Disk Problems - Prestigio Visconte 1220 User 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.
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.
