Keyboard brightness control


Look on the keyboard for the keys that might have a circular looking sun (circle with sprockets) on it. Usually they are next to each other with up and down arrows to represent increase or decrease brightness.

You will probably have to Press and Hold the FN function key located at the lower left portion of the keyboard while you hit the key that controls the brightness.

On VGN-FS640W screen is very dim, as if it were on battery. Is there some setting I can change to make brighter?


  1. Go to Control Panel -> Hardware and Sound -> Power Options.
  2. Click on "Change plan settings" for your laptop's selected power plan (either Balanced or Power saver).
  3. Now edit your plan settings by moving the sliders next to "Adjust plan brightness" at the bottom. You'll be able to change the brightness for when your laptop is On battery power, or when it's Plugged in.
  4. Once you've adjusting the brightness settings to your liking, then click on the 'Save changes' button.

To adjust the brightness control, press Fn + F5 and release, plus the RIGHT ARROW or LEFT ARROW keys to increase or decrease the value.

On most notebook computers you can use the Fn+F5 keys to lower the screen brightness level, and the Fn+F6 keys to raise the screen brightness level.

Sony Vaio vgn-fs640w does not power up nor does it


I went to the Sony Vaio support site for your model specifically and they mention a battery recall. There is a place on the site requiring specific information about your system and your battery to see if you are eligible for the recall. I would try this route to see if it resolves your issue. If not, I would say it is a blown transistor and you need to replace the motherboard. This means buying a new system, as Sony VAIO laptops are very proprietary and hard to find parts for.

Good Luck,

Sony vaio vgn-nr160e with vista, function+ keys wont work


Hi,
To enable the Fn keys functionality, you need to install the "Vaio Event Service" and "Sony Utility Series"
They are available to download as part of a package from the Sony website. Here is the link:
