Fn birghtness key not working

I have a dell inspiron 9400 and the shortcut key for increasing the brightness of the screen is not working. You usually press fn+the up arrow but nothing is happening. I know both the up arrow key and the fn key are working seperately but the command does not seem to be working together. Does anybody know what is wrong and anyway that I can fix this? Thanks,

If the "fn" key works with other "fn" command buttons it may be the drivers. Your machine came with a CD of drivers. I would visit Dell's Support website, plug in your "Service Tag" number (found on a label on your machine) and download the latest if your CD is missing. Re-install these drivers. Look into the "Dell Quickset Utility."

Yes u can by going in system and security option in control panel . After this go to Hardward and Sounds option and there you need to click on Windows Mobility Center , on opening it you will find a display brightness option ,u may use it for brightness adjustment if shortcut key is not working . Hope this will help you :-)

My Dell inspiron 1525 works fine on an external monitor, but when it come to it's LCD; it works with a very low light, I can hardly read what's displayed on it, I tried a working LCD from an other laptop,...


Try increasing the brightness of the system. Laptops have "Fn" combination buttons that allow you to use some shortcuts. Look for a button on the keyboard that usually looks like a sun or bright object with an arrow pointing up. Press and hold the "Fn" button down and press the designated button to increase brightness.

Hope this helps!

Look for a key labeled "Fn" (blue lettering) on the lower left side of the keyboard

Hold the "Fn" key and then use the Up/Down arrows to adjust brightness.

If that doesn't work, reboot your laptop and get into the BIOS. There is a screen for brightness. I don't recall how it is labeled, but it's one of the last pages as you cycle through the BIOS options.
