Troubleshooting the LCD Screen

My LCD screen is blank.

Check that the notebook is plugged into a power source and that it is turned on.

Check that the power indicator on the notebook is on.

Check that the battery pack is inserted properly and that it is charged.

The notebook may be in LCD (Video) Standby mode. Press any key to activate the screen.

The display mode may be set to external display mode. Press and hold the Fn key while pressing F7 several times.

My LCD screen continues to show the previous screen.

Press the Windows key and D twice to refresh the screen.

The image on my connected external display is not centered or sized properly.

Use the controls on your external display to adjust the image. See the manual that came with your display for more information.

I want to change the video resolution of my display.

Follow this procedure to change the video resolution of your display.

Click Start, point to Settings, point to Control Panel, and then click the Display icon.

The Display Properties dialog box appears.

Click on the Settings tab.

Move the Screen Area slider to change your video resolution.

I cannot switch the LCD display to TV, and vice versa.

Remove the DVD if it is inserted in the optical disc drive.
