Dealing with Problems (Advanced)

Sound

The sound is not heard

Try changing the mute by pressing 

Fn+F4 or Fn+F6.

Volume does not change when 

Fn+F5 or Fn+F6 is pressed

If the Windows sound function is not active, the volume will not change even if 

 is displayed.

The audio is distorted

Audio distortion may occur when operations are performed by pressing 

Fn in 

combination with another key.  Stop playing and start again.

When starting Sound Recorder, it 
displays the message: "There was an 
error updating the registry"

Sound Recorder displays this error message when started by a user with a 
limited account if the user's language setting is different to that of the user with 
the administrator authority which last started it. This will not affect the operation 
of the computer.

 Fast User Switching Function

Some applications may not work 
properly

When switching to a different user with the Fast User Switching function, the 
following problems may occur.
• Some applications may not work properly 
• Key combination with 

Fn may not work.

• It may not be possible to set the settings of the display.
• A serial mouse may not work.
• <Only for models with wireless LAN>

Wireless LAN may be used.

In this case, log off all users without using Fast User Switching function, and try 
the operation once more. If the problem persists, restart the computer.
