CHAPTER 4: Troubleshooting

38

Power

Your computer will not turn on

•

Make sure that the power cord is connected to 

an AC power source and to your computer, and 

that your computer is turned on. If your power 

cables are connected to a power strip, make sure 

it is turned on.

•

Test the outlet by plugging in a working device, 

such as a lamp.

•

Make sure that the power cord is free from cuts 

or damage, and replace any damaged cables.

Display

The screen resolution is not correct

•

Change the screen resolution in Windows. The 

computer is on, but there is no picture

•

Make sure that the computer is not in Standby 

(power-saving) mode.

•

Make sure that the monitor is connected to a 

power outlet and to a video port on your 

computer, then make sure that the monitor is 

turned on. If the monitor is on, its power LED 

should be on.

•

Adjust the monitor’s brightness and contrast 

controls. For more information, see the monitor’s 

documentation.

•

Check the video cable for bent or damaged pins.

•

Connect a display that you know works (such as 

a monitor from another computer) to your 

computer. If the display still works, the original 

monitor is faulty. If the display does not

 

work, 

either the computer’s video card (if installed) is 

faulty or the on-board video is faulty.
