Troubleshooting

#%

❑

Have your phone company check that your phone line is free from any 
line noise.

❑

If your problem is fax-related, check that there are no problems with the 
fax machine you are calling and that it is compatible with fax modems.

❑

If you are having a problem connecting with your Internet Service 
Provider (ISP), check that the ISP is not experiencing technical problems.

❑

If you have a second phone line available, try connecting the modem to 
that line.

My microphone does not work

If you are using an external microphone, check that the microphone is 
plugged into the Microphone connector. See “Connecting an External 
Microphone” on page 50 for details.

My mouse does not work
❑

If you are using an external mouse, check that the mouse is plugged into 
the mouse connector. See “Connecting an External Mouse or Keyboard” 
on page 48 for details.

❑

If you connected an external mouse while your computer is on, you must 
restart your computer.

❑

If you are using an optional Sony USB mouse PCGA-UMS1, check that 
the mouse is plugged into the USB connector.

My touchpad does not work

You may have disabled the touchpad while no mouse was connected to the 
computer. If so, you must enable the touchpad using Sony Notebook Setup. 
You can access Sony Notebook Setup from the Windows® Start menu.

I cannot use DV devices. The message “DV equipment seems to be 

disconnected or turned off” appears.
❑

Check that the DV device is turned on and that the cables are properly 
connected.

❑

If you are using multiple i.LINK® devices, the combination of the 
connected devices may cause unstable operation. In this case, turn off the 
power to all connected devices and disconnect unused devices. Check the 
connection, then turn on the power again.
