  1. Hi,

    I installed win 7 x86 on a sony vaio vpceb36fg. Everything seems OK but the Fn keys. The combination of Fn+related keys work only for sound volume and screen lock button and not for others!

    How to get all Fn keys worked please?
    Is it needed to install any tool/utility?

    Your laptop came with Windows 7 Home Premium 64 bit so I'm curious as to why you decided to install a 32 bit version.

    Laptops, particularly Vaios, have specific functions assigned to keys. On yours you were previously able to surf the web and play DVDs without booting up into Windows. To regain all that you've lost will take quite a bit of work. The utilities you need will be on a Sony support site. However, sometimes things have to be installed in a particular order before they work. It took me a long time Googling, downloading utilities and experimenting to get everything working when I reinstalled the OS on my Vaio.

    OK so now you don't remember what was the name that tool/utility for activating all of Fn keys?

    You need all the drivers and then you need to work out the correct order to install them. The big hold up for me was something called the Sony Firmware Extension Parser driver. It wasn't on the Sony site with all the other drivers. Remember that you have installed a 32 bit version of Windows 7 when looking for it.
