My laptop computer screen is black
Follow the below steps to help solve or locate the cause to a black or blank laptop computer screen.
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 below link 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.
If your laptop is in warranty, it's recommended you contact the laptop manufacturer for directions on how to get the laptop repaired.
If the laptop is not in warranty, unfortunately, for most end-users repairing a bad LCD on a laptop can be too complicated or may result in further damage if not done properly. Which is why for most users, we suggest having a repair shop repair the laptop. However, for those users who want to replace their LCD themselves, below is a listing of companies that can send replacement screens for almost any laptop.
