Does it seem like it booted up all the way except the screen is black? If so try the steps below.

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.

Press Fn+F7 to switch displays You can do it 2 times to see if it activates.
Use Fn+F5 to activate to see if u need to turn the brightness up. Then Right key.
if that didnt work turn your computer off and disconnect every thing turn it back on and tap your F8 to get in safe mode.
You can go here to see if you need updates...which maybe u already have done.

PRESS FUNCTION (FN KEY) AND KEEP IT PRESSED DOWN AND THEN PRESS USALLY F5, SHOULD HAVE A PICTURE OF A LITTLE SCREEN ON IT

Kindly press fn+num at the same time and check if it will work...

Your laptop probably has the option to display:
* laptop screen only
* external screen only
* both screens

If your laptop has a key (usually BLUE) labelled FN,
check the other keys that also have BLUE labelling.
Hold down FN, and press the appropriate other BLUE key,
to cycle through the above 3 output options.

the function keys doesnt need any extra driver.

but if you want to use tha additional features of function key like save, load, close and many more then you can get the software directly from official website of sony. alternativel you can download hotkeycontrol xp by which you can reconfigure you keyboard to add extra feature and options

Try hooking up a different monitor. If that is not an option try looking for a key in the F-keys row that has a pic. of two monitors that might even say lcd on one of them. Hold down the Fn key and push the key with the pic once. If not then push the key twice before letting off the Fn key. And so on

Easy Fix! There seems to be a connection problem. If it still powers on, the problem is cable that sends the sigal to the screen. All you have to do is open up the laptop and replace the wire. Simple!

Plug in an external monitor and use the F key with the FN to toggle between lcd and external monitor. On my laptops It is the FN and F5. If the external monitor works the problem is the the inverter board, the flex ribbon cable or the LCD. If the external monitor is also messed up then the problem is probably the video card/ motherboard.
