How to control brightness on Sony VGN SZ-series laptop after Windows 7 upgrade?

I liked Windows 7 so much on my desktop machine that I took a chance and upgraded my Sony VGN-SZ2XP laptop as well - to Windows 7 Home Premium - knowing that Sony were not making Windows 7 drivers available for their old XP machines.

"I have found a solution to allow brightness to be changed using Fn+F5 and Fn+F6!

As instructed here, I downloaded from Sony and installed the following, in this order, rebooting after each step:

VAIO Event Service
Sony Utils DLL
Sony Shared Library

After this, the Fn key worked fine - I've tested it with F2 (mute), F3 & F4 (volume), F5 & F6 (brightness) and F12 (hibernate). This makes a tremendous difference to the usability of this machine on Windows 7.

Huge thanks to harrymc for the correct download location on the Sony website, which I had failed to find.

By the way, Brightness still doesn't appear in ""Windows Mobility Center"" - but that doesn't matter now."

"Just found this article, that shows how brightness can be controlled by the keyboard by tweaking in the BIOS the ""Brightness Mode Control"" to ""User Control"":

Another remark from the article is:

The Brightness slider for me is in the
‘Change plan settings’, underneath the
drop downs.

Hope that helps!"
