User's Manual
Procedure
Try adjusting the contrast and brightness controls
on the external monitor.
Press the function 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 the function key 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
Check for a firm cable connection between the
LAN jack and the LAN hub.
Make sure the AC adaptor is connected. The
Wake-up on LAN function consumes power even
when the system is off.
If problems persist, consult your LAN administrator.
