Hello manando,

Have you tried to take out the battery and the power cord and to press the power button for about 30 secs? If you haven't you should try to do so. Can you hear the fan or the hard drive spinning when you're trying to boot the lappy? If you can, it's recommended that you connect the laptop to an external monitor to see will there be any video signal going out from the laptop. If it does go out, then there's a need for LCD inverter replacement. If there's nothing showing either on external monitor nor display, but the fans are still working, the problem that you have may be due to the failure of the video chip. Sometimes, after much of a use and less cooling the graphics processor which is responsible for video signal transmission get unsolders, the thermic paste goes away and it gets unsoldered, therefore the screen doesn't show anything. If you know some stuff about the laptop's hardware you can change the thermic paste yourself by opening the laptop and checking if the chipset that is next to the processor has got unsoldered or you can bring your laptop to a technician to get it soldered again.

Hope I gave you some ideas. Cheers.
