Procedure
Try adjusting the contrast and brightness controls
on the external monitor.
Press the FN + F5 hot key in order to change the
display priority and ensure that it is not set for the
internal display only.
Check to see if the external monitor is connected.
When the external monitor is set as the primary
display device in extended desktop mode, it will not
display when the computer wakes up from Sleep
Mode if the external monitor has been
disconnected while in Sleep Mode.
To keep this from happening, do not disconnect
the external monitor while the computer is in Sleep
or Hibernation Mode.
Remember to turn off the computer before
disconnecting the external monitor.
When the display panel and an external monitor
are set to clone mode and they are turned off by
the timer, the display panel or the external monitor
may not display when turned on again.
If this occurs, press FN + F5 to re-set the display
panel and external monitor to clone mode.
Check that the cable connecting the external
monitor to the computer is firmly attached.
If you are still unable to resolve the problem,
contact TOSHIBA Support.
Procedure
Make sure the computer's internal modem settings
are correct - please refer to the Phone and Modem
Options link within the Windows Control Panel.
If the call is going through a Private Branch
Exchange (PBX), take care to ensure that the
communication application's tone dial detection
feature is disabled.
