Update first the firmware of your laptop. If the problem still occurs then contact your vendor for warranty there must be wrong on your screen's bezel and LVDS cable.

S1 and S2 buttons are called special Function keys.
By default, the S1 button turns the Volume On or Off and the S2 button toggles the display between the LCD and the external devices. You can also change these buttons assignments on the window for changing the S button assignments. To display this window, press and hold either button or launch and navigate through VAIO Central (Start, All Programs, VAIO Central).

Good Luck!!!!

i have the same problem with fifa 10 Sony Vaio VPCEC1M1E when i play with other usb keyboard its working but with my laptop keyboard ist working..

The solution is as follows, which worked for me:

- Install Windows 7
- let it update all the drivers that it needs to
- Install additional Sony drivers that you need (XP drivers work just fine, but make sure to install them in Administrator mode, so, Run as Administrator), such as camera, fingerprint scanner, etc
- Install the Notebook Control Device Driver (without this the other software does nothing)
- Sony Utilities DLL
- Sony Shared Library

* restart computer *

- Sony Video Shared Library
- SUS (Setting Utility Series)

* restart computer *

- VES (VAIO Event Service)

After this one the Fn keys will start to work. The S1 and S2 keys don't work due to something to do with UAC (but I don't need them anyway)

- VAIO Control Centre (will allow you to change what the S1 and S2 keys do, even though you can't use them :) )

That's it and it worked for me.

You must have received a Cd with your Sony Vaio model, u need to install th e software again.

eBay is the best place for this type of thing. It's way cheaper than any laptop depot I've come across. Here's one for your keyboard: http://cgi.ebay.com/Sony-Vaio-Laptop-Keyboard-VGN-T140P-HMB991-D01-NR_W0QQitemZ320137022753QQihZ011QQcategoryZ140084QQssPageNameZWDVWQQrdZ1QQcmdZViewItem As far as the screen is concerned; the way to get the best deal is to search by model number of the screen and not just laptop. The same screen can be used in several different laptops. Take your screen out and look on the back of it. There will be a model number there. Enter that model number into ebay's search, making sure you check product description to be included in the search query. Any screen matching that model number will fit your laptop just perfectly and it will save you a bundle.
