Settings

• You may be able to adjust the settings of your laptop screen through the operating system's configuration. Windows users can do this by using a program that will calibrate screen brightness automatically or they may choose to adjust the brightness manually using buttons on their keyboard. Exact buttons and instructions vary with different computer models.
  
  

Operating System

• The operating system itself may be the problem, however, and extra files may be required. The operating system may have a limit on how high it can adjust the screen and this limit may be below the user's preference. Check your operating system's user manual or online help system for more information.
  
  

Laptop Manufacturer

• Different computer brands have different ways of adjusting screen brightness. You may want to check your laptop's manual or download it from the manufacturer's website. Many laptops will adjust brightness through a special combination of keys.
  
  

Backlight Malfunction

• There may be a physical problem with your computer's backlight if none of the other approaches work. This will most likely require that you take the laptop into a computer technician for repairs. Talk to the manufacturer or retailer to find out if your warranty applies or if you have any special service programs.
