does HDD work at bootup..

The laptop power button shows green, but the third light (HDD) does not light up.. the monitor is also pitch dark/black..

does that confirm that the boot up is not happening?

i would say yes, maybe the cpu died, because everything else like graphic, ram etc should be give you a beep code from the bios.

and as you mentioned, if e.g just your display is failing and you just see nothing because of that, the laptop should load bios, post etc and go into windows where you then can see or maybe feel / hear that the harddisk is loading.

let me guess, the problem came just from one day to another?

Here you have the list of things that computer does at start-up:

try connecting the laptop to an external monitor just to exclude it's not the notebook monitor. If it doesn't work it could be that the motherboard died, even if you have a green light...

a cpu can 'die'? or do you mean mobo?

it won't show anything on an external monitor either.. does that tell 100% that mobo is gone?

It is not 100% but very likely.
If the laptop is not under warranty you can try to remove HDD and RAM to see if there is any difference.
Also make sure you have disconnected anything from your laptop.

You can try to remove and re-seat the battery after 2 minutes. You can also try to reset bios.

i guess is just when mobo don't make noises when the screen is black, for me its just then 2 reasons, cpu is broken or mobo is broken, just remove ram as you where told and hdd but usually if something hardware related happens and fails the mobo will give you some beep codes, except mobo is broken or most times ( in my experience ) when the cpu is broken.

btw how to reset the bios when you see nothing? ;)

For Sony products it is always difficult find service manuals.
In this article the author tried to disconnect RTC battery - but you will have to dismantle whole laptop.
http://www.insidemylaptop.com/take-apart-sony-vaio-vgn-fz220-repair-power-jack/
I have posted this link because in step 14 it is shown the location of RTC battery.

This should be the procedure for dismantling your laptop. On page 2 you can see the location of RTC battery.

Anyway if the laptop is in warranty I would recommend you to contact Sony Service Center. Also I would recommend the same if you don't have experience in laptop repairing or if you don't feel comfortable with it.

"btw how to reset the bios when you see nothing? ;)"

Reseting bios is hardware procedure and in most motherboard user guides the procedure is described.
Normally it consists of unpluging power cord, removing onboard RTC battery, shortening pins on "clear RTC" jumper for 5-10 seconds and reinstalling the battery.

I agree with davorin if you arn't comfortable following these proceedures take it to someone who is.

First check your manual to see if the notebook isn't hibernating or in suspend mode.

1. Disconnect the AC power, remove the battery pack, press and hold the Power button for 20 seconds. Re-insert the AC adapter and see if it will power on.

2. Disconnect the AC power, remove the CMOS Battery for 5 minutes. Re-insert the CMOS battery. Re-insert the AC adapter and see if it will power on.

3. Disconnect the AC power, remove the Hard drive. Re-insert the AC adapter and see if it will power on.

4. Disconnect the AC power, remove and clean the golden edge of each memory stick with a soft rubber/eraser, remembering not to touch the golden edge of the memory stick.  Re-insert one stick at a time to test. Re-insert the AC adapter and see if it will power on.


Check the movement of the Lid Actuator switch

The Lid Actuator switch is a small button or switch located above the keyboard near the hinge for the LCD. Pressing this switch 2-3 times when the computer is on may turn the notebook display back on.

here my laptop troubleshooting guide :
-remove all external devices
- if no display - test with an external monitor
- test if it runs from battery alone, or from AC alone
- test also with a known good battery !
- remove battery and AC adaptor, hold power button for 20 sec, connect AC and reboot --> any display ? if NO -->
- disconnect all disk and cd drives, battery , and other cards and peripherals, leave only 1 ram stick
- boot -->any display ?
- if NO remove all ram and reboot --> if NO beeps, mobo or cpu bad ; if it beeps, replace ram stick
-if you can access the bios battery, remove the battery, AC, and bios battery for a minute to reset the bios
or test it, it should read 3 V
*** you can test the disk on another pc, if you like !

I guess the mb is dead, just get an external hd case to insert the laptop's hd so you can access your data
