Is the Notebook Screen Blank?

If you have not turned off the notebook but the screen is blank, the notebook might be in standby or hibernation, or not set to display the image on the notebook screen.

To resume from standby or restore from hibernation, briefly slide the power switch.

Standby and hibernation are energy-saving features that can be initiated by the system while the notebook is in Windows but is not in use.

When standby is initiated, the power/standby lights blink, your work is saved in random access memory (RAM), and the screen clears.

In some software, including your Windows operating system, the term standby is replaced by the term sleep.

When hibernation is initiated, your work is saved to a hibernation file on the hard drive, the notebook shuts down, and all power lights are turned off.

For more information about standby and hibernation, refer to the Hardware and Software Guide.

To switch the image to the notebook screen, press fn+f4.

On most notebook models, when an optional external display device, such as a monitor, is connected to the notebook, the image can be displayed at any time on the notebook screen, the external display, or on both the notebook screen and the external display simultaneously. When you press fn+f4, the image is switched among the notebook, one or more external display devices, and simultaneous display.

On some notebook models, the function of fn+f4 is determined by the software you are using. For information about the fn+f4 functions on your notebook, refer to the hotkeys section of the Hardware and Software Guide.
