How to Fix Dell Laptop Horizontal Lines on the Screen?

If you notice horizontal lines on your Dell laptop screen, there are several steps you can take to alleviate the issue.

Adjust Power Management

The primary cause of horizontal lines on Dell laptop screens is often incorrect power management settings. When the computer is turned off or in sleep mode, the graphics processor can remain active and consume significant power. This can lead to premature display turn-off or flickering, resulting in the appearance of horizontal lines.

To address this problem, adjust the power management settings on your computer by following these steps:

  1. Start the menu and select Settings -> Power -> Change plan settings -> Change advanced power settings -> Battery saver -> Turn on battery saver (see image).
  2. From here, you can set the time for automatic computer turn-off and the duration before it turns back on.


LCD Panel Troubleshooting

LCD panels consist of various materials that require heat to function properly. To ensure the monitor screen operates correctly, follow these steps:

  1. Turn off your laptop.
  2. Wait approximately an hour after turning off the laptop before attempting to turn it on again.
  3. After turning on the laptop, wait a few seconds and then move the mouse to verify its functionality. If the mouse doesn’t work, try turning on the laptop using the keyboard or touch-pad.
  4. Turn off the laptop again.
  5. Wait another hour before turning it back on.

If you continue to experience screen issues, it’s advisable to take your laptop to a service center for further assessment.
