Boot Failure

Hello,
My Acer Travelmate 2450 stoped booting.

THere is NO POST screen, nor bios, not the Acer logo
WHen I power it up, the power button gets lighted up.
Otherwise, the screen stays blank, black and dark.

THe HDD led lights on continiously and sometimes it doesnt.

In short, the netbook does not respond nor give any message
