Now you have to replace the laptop, or you need some repairs for the laptop. You feel uncomfortable thinking that now your laptop is gone forever. But suddenly, you noticed the cooling fan of the processor is still making a noise. After hearing some noise, you feel some comfort that some portion of my laptop is working.  Now, you come to a result that maybe only the laptop screen has faced the issue and all other things are all right. Congratulations! Your thinking is correct.

    The other issue that you can face about dell’s laptop screen is that the dell’s laptop screen goes black randomly. I will also tell you in this article about how to solve the problem.

    Now in this article, you will learn diagnostics and solution of this fault. And also learn how can you possibly fix this dell laptop black screen issue?

    Causes of Dell laptop Black Screen

    According to customer feedback, the Dell laptop’s black screen is a common issue. Some customer-facing permanent black screen and some are facing the randomly black screen. In a randomly black screen, you see the screen’s normal function for 5 seconds and after 5 seconds screen goes black. This black screen reverses to its normal function after some time. This process continues in the same manner.

    In this case, you are facing a random laptop black screen that can disturb you more because you cannot receive any error code or message that might help in the eradication of fault.

    Here are some common reasons for laptop screen blackout.

    Miss matching between graphic drivers and OS

    Suppose graphic derivers and the Operating Systems are not compatible with each other, then the dell laptop screen can face problems.

    Outdated Display Driver

    If the display drivers are outdated, then this is a widespread issue of whether laptop screens become permanently or randomly going black.

    Wire Breakage

    If the wire that connects the LCD screen and motherboard of the dell laptop is damaged, the laptop screen will be permanently black.

    Overheating of Graphic card or Processor

    Another reason for the black screen problem is that when the Graphic card or the processor gets excessive heat, then the dell laptop screen goes black at regular intervals. Due to this overheating system can also crash.

    Virus

    The virus is also a major cause of laptop screen blackout. Some hidden viruses or malwares can choke the dell laptop. As a result, we see only the black screen of the laptop while the laptop is running.

    Faulty Power Supply

    If the power supply malfunctioning or faulty, this could be a possible reason for the black screen.

    Operating System Installation Issue

    If an operating system like Windows 10 is not correctly installed. Then it cannot handle the dell laptop’s hardware and screen. As a result, the screen of the Dell laptop goes black.

    Faulty Laptop Screen

    At last, the cause of the Dell laptop black screen is that the LCD screen is expired. It usually happened when physical damage is accrued or the life of the screen had passed.
