I would first take out the battery and the power adapter. Press and hold down the power button for about 40secs. Re-install the power adapter and try again.

cheers ...

Right, try removing and re-seating the ram modules, or just leave one out if you have 2.

cheers ...

Re-seat the hard drive? Try booting with an installation CD?

By the way, please refrain from editing your OP once you got some replies back. Just amend the inputs onto a new post. It kinda make the responses to you look stupid ;-) "as I was "

cheers ...

You mentioned that you try with another ram. Did you do it on one slot, and then the other slot also?

I was thinking about any FLASH DIOD ERROR CODES or some similiar to find what component is damaged or bad, but I nothing found...
IS true, that 3 days ago was possible notebook sometimes turn on, but from any moment just no boot, no screen, only led diod disco and darkness.

Hot dog, you are sure a tinkerer

Try with the HDD and the installation CD and see. If that won't go, once can probably kiss the motherboard goodbye I guess. Good lucks.

Hard to say on certain brands/models. Usually it should just post and then say no OS found. Does not hurt to try.

That is another (last) possibility. You have the whole machine apart, so replacing it would not be so hard.

How did the notebook come to not working?

I not believe that is this damaged MotherBoard PCB.
But maybe the led blinking is only not passed power on selft test and i here only lost my time.

So, no go an the HDD and the installation disk?

I am stumped then. Let us wait for MichelleG and hope for some new input.

What about replacing the CMOS battery?
