SONY notebook brightness cannot be adjusted problem

SONY notebook Fn key combination cannot change the brightness

I have encountered this problem before. After I reinstalled the system, all the shortcut keys on the keyboard became invalid.

I consulted customer service via 800-820-2228, downloaded several drivers, and after installation, the problem was successfully solved. Now share the method with you.

First log in to the following page:

After selecting the notebook model you are using, you will see a list similar to driver downloads.

Find the "VGN-**** series original application" under "Original Driver Download" (**** is the specific model of your machine) and click to enter. Click "Continue" at the bottom of the page, then click "Agree" once you're on the page.

First, please find the driver "Sony_Shared_Library", download and save it. Then find "Sony_Utilities_DLL", download and save. Finally, find "VAIO_Event_Service", download and save.

Please remember to install these three programs in order according to the above download order. After each installation of a program, be sure to restart your computer (if it does not restart automatically, please restart manually). A total of three reboots are required so that your shortcut keys work properly.

If you still have questions, you can send me a message on the site.

What should I do if the fn key on my Sony laptop cannot be used?

1.Sony Shared Library

2.Sony Utilities DLL

12....... SONY notebook hotkey program (HotKey Utility), you need to install SonySharedLibrary → Sony UI Library → Sony Utilities DLL first. There should be its driver on your random system installation disk.

In addition, the FN key must be used together with other keys with blue functions to play its function key role.
