Dell is a major player in the laptop market, known for its quality products. However, several issues have recently plagued Dell laptops, from lines on the screen to random shutdowns, leaving users frustrated.
This problem typically arises due to a defect in your laptop’s screen, and the good news is that you can often fix it yourself. Nevertheless, resolving this issue might pose a challenge. In this guide, we’ll walk you through the process of rectifying Dell laptop horizontal lines on the screen.
What Causes Dell Laptop Horizontal Lines on the Screen?
One of the most common problems people face with their Dell laptops is the appearance of lines or other issues such as burn marks on the screen. While Dell laptops are renowned for their beautiful screens and sharp images, certain problems, like horizontal lines on the screen, can occur. Poor manufacturing quality is a key factor contributing to this problem.
Horizontal lines may appear on your laptop screen for various reasons, including:
- If the laptop is over a year old.
- When the computer’s temperature becomes excessively high.
- If the screen pixels become damaged.
- If the screen is covered by something heavy.
- When dust and debris damage the laptop’s pixels.
- Due to certain external devices connected to the laptop.
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:
- Start the menu and select Settings -> Power -> Change plan settings -> Change advanced power settings -> Battery saver -> Turn on battery saver (see image).
- 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:
- Turn off your laptop.
- Wait approximately an hour after turning off the laptop before attempting to turn it on again.
- 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.
- Turn off the laptop again.
- 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.
