Laptop Screen is Always Black When Turned On (The Black Screen of Death)

When you turned on your laptop, only black screen appears. This had been a common problem specially for laptop users and been commonly know as the "BLACK SCREEN OF DEATH". There are other two types which is the white screen and blue screen which will be answered in different post.

Now regarding to your problem with this, I suggest you try the following procedures. Usually it is a software problem in which in case a virus had affected your system that's why it won't boot. The more problem is when it is a hardware one since laptop parts are much expensive than the desktop ones.

Computer is not booting properly

Although you may not be able to see anything on the screen, listen to the laptop and make sure it sounds as if the computer is booting. If it does not seem to be booting properly or it sounds different follow the steps in the link below before trying any of the other steps on this page.

Brightness is set low or power setting

If the picture is partially visible often it is only the laptops brightness that is set low or a power setting is decreasing the brightness. Make sure your laptop is not in a power saving setting by plugging the laptop into the wall. Next, try increasing the brightness on your laptop to verify it is not the brightness causing your issue.


Try external display

Verify there is not an issue with the laptop video adapter by connecting a monitor or other display to the laptop. If the external display works fine, it's an issue with your laptop display.
 
If an external monitor is also not working with the laptop and you've read through the above link, the internal video adapter or cable is defective and not the display.
Other hardware issue
If after following the above steps, the laptop still has a black or blank screen your laptop has a hardware issue. Below are the most common hardware failures.
  1. Loose or disconnected cable
  2. Bad LCD power inverter.
  3. Bad CCFL or backlight.
  4. Bad LCD.
If this is the problem, I suggest you contact your supplier for technical support.
