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.

•Try adjusting the size of the desktop icons and labels—see “To adjust the display” on page 33.

If an external display does not work

•Check the connections.

•Press Fn+F5 in case the external monitor was disabled. (Do this three times to return to the state you started from.)

•The external monitor may not be detected. In the BIOS Setup utility, try setting Video Display Device to Both in the System Devices menu.

•If you’re using a TV connected to the S-video port, you must activate the TV—see “To use a TV set as a monitor” on page 81.

•Test the display with the e-Diagtools diagnostics—see “Testing the Hardware” on page 116.

If Presentation Ready does not switch to your video settings

•If you’re using an external monitor that isn’t a plug-and-play device, open Control Panel Display and set up a monitor that supports the video settings you intend to use for your presentation.
