Troubleshooting Problem No display Display error occurs 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 panel 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 the monitors 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 your reseller, dealer or service provider. Modem This information is applicable to the models equipped with a built-in modem. Problem Procedure Communication software can't initialize modem Make sure the computer's internal modem settings are correct. Please refer to the Phone and Modem Options link within the Windows Control Panel. You can hear a dial tone but can't make a call 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.
