Problem: Blank screen or no image is displayed on the monitor

Troubleshooting and problem resolution:

1. Check that the monitor has been turned on; if not, press the power button.

2. Check to see if the monitor power cord is loose; if so, securely plug the power

cord to the monitor.

3. Check that the signal cable to the monitor is securely connected to the

connector on the computer graphics card; if not, shut down the computer then

securely connect the signal cable of the monitor.

Problem: You need to change display property settings

Setting display background and icon properties:

1. Right-click the desktop anywhere except over an icon, then select Personalize

from the pop-up menu.

2. From here, select the appropriate options to:

• Change the desktop background

• Select a screen saver

• Select colors and appearance options for icons and characters

• Set resolution and colors by using Display Settings options.

Problem: Ripple on screen

Troubleshooting and problem resolution:

1. Check for devices located less than one meter from the computer such as

refrigerators, electric fans, electric dryers, UPSs, regulators, ﬂuorescent lamps

or other computers that may be generating magnetic interference.

2. Move any interfering devices away from the computer.

3. If the problem persists, consult with Lenovo Service.

5.2 Troubleshooting audio problems

Problem: When you connect the headphones to the front audio output connector,

the speakers connected to the back audio output connector are silenced.

Troubleshooting and problem resolution:

The front audio output connector is provided for convenience and has a priority

higher than the back audio output connector. If a speaker or headphones are

connected to the front audio output connector, sound is delivered through those

devices and any devices connected to the rear connector become silenced.
