My Laptop Dosent turn on

Hello,
My problem is with my Laptop, Philips freevents x56. When you press the button to turn on, the green light in front comes on as usual, but no sound of any device like fan/dvd/screen. nothing works. Only thing I can say, CPU gets warm...
I read the previous topic and removed the RAM and pressed the turn on button, still the same, no sound or screen, power light comes on as usual...
I checked all cable connections, look fine...
Thanks in advance for your help...
