Hi Dimitar,
We often hear users telling us that they not able to use Fn keys such as the fn for wireless, sleep, etc.
In fact, you need to install power management software and drivers whereby it has hotkey driver included in it. Hotkey driver is the key to make sure the Fn keys work. http://consumersupport.lenovo.com/ge/en/DriversDownloads/drivers_list.aspx?CategoryID=10
P.S. This apply to only Lenovo Essential and Idea machines. Exclude Think machines.
Go there : http://pc-dl.panasonic.co.jp/itn/drivers/d_menu_en.html Choose your model, OS, language. Select Category=All Drivers. From the list, download and (re-)install the Hotkey Manager Driver, Hotkey Settings Application, and Hotkey Appendix Application.
The problem is that the Fn Hotkey Utility breaks when XP SP2 or some other patch goes on. You can fix this by using the Vaio Recovery Wizard. Click on it, then Proceed With System Recovery, Custom Recovery, Application Recovery. Select HotKey Utility then Repair. It takes a reboot and works after that.
This is a skill you will get good at with a Vaio as it seems that every driver update or patch from Microsoft will break something. I hope this helps!
You need to install an ATI Hotkey driver. Please go to this website and choose your model an operating system:

You will then be shown a list of all drivers. There you should find the hotkey driver.
Decrease Brightness (fn+f7) The fn+f7 hotkey decreases the brightness of the notebook screen. The longer you hold down the fn+f7 hotkey, the more the screen dims. Decreasing screen brightness conserves power.» To increase screen brightness, press the fn+f8hotkey.
Increase Brightness (fn+f8)The fn+f8 hotkey increases the brightness of the notebook screen. The longer you hold down the fn+f8 hotkey, the more the screen brightens.» To decrease screen brightness, press the fn+f7hotkey.
search for v3515 you will find a list of drivers , scroll down a alittle and you will find hotkey utility , download it , install it ...... try the buttons :) MAGIC
check under your "processes" in the Windows Taskmanager and see if you can find anything listed that starts with "hk" like "hkserv", "hksrv" or "hkcmd" .. That would be your hotkeys, if they were working. :)
This means the driver for your hotkeys is missing or corrupt.
Now, go to this site here: http://esupport.sony.com/perl/select-system.pl?PRODTYPE=24&NAVDISP=pc
and enter all your info (like model number, ...), then you'll be able to download the proper hotkey driver for your model Vaio.
write back if it worked.
regards,
Tom
