CD included with your computer for a more complete list of troubleshooting
suggestions.

Display Problems
If the computer is on, but the screen is blank
• Move the mouse or tap the touch pad. This will wake the display if it is in Display-off
mode.
• Press Fn+F5 in case the internal display was disabled. (Do this three times to return to
the state you started from.)
• If the computer is cold, allow it to warm up.
If the screen is difficult to read
• Try setting the display resolution to its default setting of 1024×768 or higher,
depending on your model: click Start, Control Panel, Appearance and Themes,
Display.
