Laptop Black Screen

 

If your laptop screen does not display any images, the following steps will help to resolve the issue.

Laptop battery issue

Battery errors can cause problems with starting the laptop and displaying anything on the screen. Although you can charge it at full capacity, a battery defect can interfere with the laptop's boot process.

• Disconnect the power adapter from the laptop.

 

• Remove the laptop battery

 

• Press and hold the laptop power button for 10  seconds to discharge any stored power.            

     

• Connect the power adapter to the laptop again

.

• Press the power button to see if the laptop turns on and displays anything on the screen.      

Operating system issues

A corrupted system file can be one of the main reasons for this problem, preventing the operating system from loading and resulting in a black or blank screen.

If it's a temporary problem, restarting Windows will fix it automatically. If the problem persists, you should try to repair the operating system, and if that fails you will have to reinstall Windows.

 

Brightness is set low or power setting

If the picture is partially visible, the laptop's brightness is too low or turned down by a power setting. Make sure your laptop is not in a power-saving mode by plugging the laptop into the wall. Next, try increasing the brightness on your laptop to verify that it is not causing your issue.

 

External display screen

Connect the laptop to a computer monitor and test.

If the monitor is working properly, it may be a problem connecting your laptop LCD screen or motherboard to the LCD screen.

If the external monitor does not work, the internal graphics card, motherboard, or video cable is faulty. You may need to replace the graphics card or motherboard.

Laptop overheating

Check if the laptop is overheating. In most cases, the laptop shuts down when overheated; However, it can only deactivate the display by turning off the power to the GPU (graphics processing unit).

 

Another hardware issue

If the laptop still has a black or blank screen after following the steps above, it could be due to a hardware issue. The list below shows common hardware failures.

1.  Loose or disconnected cable.

2.  Bad LCD power inverter.

3.  Bad CCFL or backlight. (cold cathode fluorescent lighting)
