Sony Vaio doesn't boot
Laptop Sony Vaio VGN-C1Z
After pressing start button this happens:
CD drive on: I hear its noise
Hard disk on: only rotate, no heads moving noise
Green upper LED (over keyboard): always on
Display: always black, no sign of booting or S.O. loading
CPU fan: off, never starts to rotate
CPU: become hot, as if it was operating
I tried to insert a brand new RAM module: nothing changes.
Same behavior with only power supply, only battery or both.
What do you think?
