We always want the user experience on our laptops to be the best. Laptops are excellent portable devices used for work, entertainment, and whatnot! To keep them functioning optimally and smoothly, nearly everyone runs system health and protection programs.
Despite all the care, it is very annoying when you see some problem with your laptop. One such annoyance is black spots. Black spots could appear on your laptop screen for many reasons.
Whatever the cause of the black spot, each will be explained in the course of this short guide with step-by-step solutions explaining how to fix black spots on a laptop screen.
Before knowing the causes and solutions for black spots in detail, let’s first learn:
How to Observe or Locate the Black Spots on the Laptop Screen?
When the black spots are due to dust, they are visible even when the laptop is not running. Increase the screen brightness to the maximum for observing them clearly while you use your laptop.
- Shut down the laptop.
- Press the D key as you turn on the laptop.
- A colored screen test would then start and would determine if there is a dead or stuck pixel on your laptop screen.
- The laptop will restart as soon as BIST is complete.

Causes and Solutions: How to Fix Black Spots On Laptop Screen?
Let’s now go through the three causes and solutions for black spots:
Cause#1: Dust or Debris
You have anticipated it right! Dust or debris is the most common cause of dark spots on laptop screens. No matter what we do, the dust in the atmosphere accumulates in our computer system.
It is also fine that you clean the black spot after it has formed because dust does not harm either the screen or the internal circuitry.
How to Fix the Black Spot Caused by the Accumulation of Dust?
You can easily fix this by wiping the Black Spot using a soft cloth and cleaning liquid. Follow the guidelines and procedure to do so.
- Use a microfiber cloth. If you use macro fiber cloth or tissue, it could leave stains and sometimes also cause scratches on the laptop screen.
- Do not use alcohol, ammonia, or acetone products as the cleaning liquid because they could damage your laptop screen. Mix equal quantities of vinegar and water and you will have a fine screen-friendly cleaning liquid.
- Turn off your laptop.
- Moisten your cloth with the cleaning liquid.
- Gently clean the black spot.

Cause#2: Stuck Pixel
A stuck pixel is also a common cause of black spots.
A pixel changes color as we use a display device. As the name of the stuck pixel suggests, it does not change color.
There are three sub-pixels of a pixel which are either green, red, or blue. A stuck pixel would have only one of the three colors, which seems to be a black spot on the screen.
Cause#3: Dead Pixel
As compared to a stuck pixel which shows one color, a dead pixel does not have any color. A pixel illuminates when a laptop is on. A stuck pixel also illuminates but a dead pixel doesn’t. This means that all of the sub-pixels of a dead pixel are dysfunctional.
How to Fix Black Spot Caused by Dead or Stuck Pixel?
Black spots caused by dead or stuck pixels could be fixed by using both external methods and software programs.
By using Physical Pressure
- Locate the stuck or dead pixels. (See ‘How to Observe or Locate the Black Spots on the Laptop Screen?’ above)
- Start by gently cleaning your laptop screen.
- Stick some adhesive tape pieces on the sides of your screen according to the location of the stuck or dead pixel. Stick one on the side of the pixel and one above it.
- Shut down the laptop.
- Take a microfiber cloth and wrap it around the eraser part of a pencil or the front part of a stylus pen.
- Gently push the eraser side of the pencil or the stylus on the damaged pixel for 10 seconds.
- Repeat Step 6 for 15 to 20 times, while taking breaks in between.
Note: Do step 6 carefully as you could puncture your laptop screen by using excessive force.
This is the external way of fixing your black spot problem. If this doesn’t work, proceed to the following software solutions.

Black spots could surface for three main reasons which are dust, stuck pixels, or dead pixels.

If it will be under their policy, they could also possibly give repairs too.
