The built-in display is blank when you turn on your notebook.

1.Something is pushing on the Closed C over switch. (See Figure 1-7 on page 8.)

2.The notebook is set for an external monitor only.

3.The angle of the display and the brightness settings are not adequate for your lighting conditions.

4.The power management timeouts may be set for very short intervals and you failed to notice the display come on and go off again.

5.The notebook turned on with a series of beeps.

1.Clear the Closed Cover switch.

2.Pressing F10 while holding down the Fn key allows you to change your selection of where to send your display video. Each time you press the combination of keys you will step to the next choice. The choices,in order, are built-in display only, external monitor only, both built-in display and external monitor.

3.Move the display and the brightness control until you have adequate visibility.

4.Press any key or move the pointer, if this doesn’t work press the Suspend/Resume buttton. (The display may be shut off by Standby mode, Auto Suspend, or Video Timeout.)

5.Power On Self Test (POST) has detected a failure which does not allow the display to operate. Contact your support representative.
