What Causes Black Spots on Laptop Screens?
Black spots on your laptop screen, or what we call "mancha preta tela notebook," can appear for several reasons. It's essential to identify the cause before jumping into solutions. Here are some common culprits:
Physical Damage
One of the most common causes of black spots is physical damage. If your laptop screen has been dropped, scratched, or pressed too hard, it can lead to dead pixels or permanent damage to the screen's surface. Dead pixels occur when individual pixels on the screen stop working, resulting in black spots.

Software Glitches
Sometimes, black spots aren't caused by physical damage but rather by software issues. Corrupted drivers, outdated firmware, or system malfunctions can cause parts of your screen to appear black. These issues can often be resolved by updating your software or reinstalling drivers.
Hardware Malfunctions
Hardware problems, such as faulty backlighting or damaged LCD panels, can also lead to black spots. If the backlight in your screen fails, certain areas may appear darker or completely black. This is usually a more serious issue that may require professional repair.
Software-Related Issues and Fixes
Before assuming the worst, it's a good idea to check if the black spots on your laptop screen are caused by software issues. Here's how you can troubleshoot:
Update Graphics Drivers
Outdated or corrupted graphics drivers can cause display issues, including black spots. To fix this, follow these steps:
- Go to Device Manager and locate your graphics card.
- Right-click on it and select "Update driver."
- Choose "Search automatically for updated driver software."
Check for System Updates
Make sure your operating system is up to date. Windows and macOS frequently release updates that can resolve display issues. Simply go to your system settings and check for available updates.
Perform a System Restore
If the black spots appeared after a recent software change, performing a system restore might help. This will revert your system to a previous state, potentially eliminating the issue.
Hardware Problems and Solutions
If software fixes don't work, it's time to investigate hardware-related causes. Here's what you need to know:
Dead Pixels
Dead pixels are individual pixels on your screen that no longer function. While they can't be repaired, there are tools available that can sometimes revive them. Programs like JScreenFix can help detect and fix dead pixels, although success rates vary.
Backlight Failures
A failing backlight can cause parts of your screen to appear darker or completely black. If this is the issue, you may need to replace the backlight component. This is typically a job for a professional technician.
Screen Damage
If your screen has been physically damaged, the only solution may be to replace it entirely. This can be costly, but it's necessary to restore your laptop's functionality.
How to Prevent Black Spots
Prevention is always better than cure. Here are some tips to help you avoid black spots on your laptop screen:
- Be gentle when using your laptop—avoid pressing too hard on the screen.
- Use a screen protector to shield your display from scratches and impacts.
- Regularly update your software and drivers to prevent glitches.
- Avoid exposing your laptop to extreme temperatures, as this can damage the screen.
Screen Maintenance Tips
Proper maintenance can extend the life of your laptop screen and prevent issues like black spots. Here's how you can take care of your screen:
Cleaning Your Screen
Use a microfiber cloth and a cleaning solution specifically designed for screens. Avoid using harsh chemicals or paper towels, as they can scratch the surface.
Adjust Display Settings
Make sure your display settings are optimized for your screen. Adjust brightness, contrast, and resolution to ensure the best possible image quality.
When to Replace Your Screen
There are times when replacement is the only option. If your screen is severely damaged or if hardware components like the backlight are failing, it may be time to replace it. Consider the cost and whether it's worth repairing or upgrading to a new laptop.
Cost of Repair and Replacement
The cost of repairing or replacing a laptop screen can vary depending on the brand and model. On average, you can expect to pay anywhere from $100 to $300 for a replacement screen. If you're handy, you might save money by doing the replacement yourself, but be cautious—mistakes can lead to further damage.
DIY Fixes for Minor Issues
If you're comfortable with DIY repairs, there are a few things you can try:
- Use a pixel repair tool like JScreenFix to attempt fixing dead pixels.
- Check connections inside your laptop to ensure everything is secure.
- Test your screen with an external monitor to rule out software issues.
