The LCD Screen Is Blank If the computer starts up but no image appears on the LCD screen, follow these steps to solve the problem: 1. Use the brightness and contrast controls to adjust the screen display. 2. To save power, you may have set a timeout period for the LCD screen in the Setup program. This turns off the screen automatically after a specified period of time has elapsed with no keyboard input. Press any key to see if this restores the display. (See Chapter 5 for information about the power management options.) 3. Make sure the suspend/resume switch is set to the left. The computer may just be in Suspend mode. 4. If you have connected an external monitor to your computer and you are using it, you should not have any problem displaying information on both screens at the same time. Check your VGACONF settings; see Chapter 7 for details. The External Monitor Screen is Blank If you are using an external monitor and no image appears on its screen, follow these steps to solve the problem: 1. Make sure the power switches on the computer and the monitor are turned on. 2. Adjust the brightness and contrast of the monitor screen. 3.
