When I power on my laptop (Acer 5742G) I found there is no HDD LED activity, no BIOS welcome message, Nothing is on the display. But the Power LED is continuously on. Exhaust fan was running. Dont know what's the problem. I've checked my HDD by attaching into another laptop and it is working good.

sometimes my power button sticks as if I was holding it down. the fan runs but nothing else happens.
I rock the button back and forth to loosen it, then hold it down to crash the mobo.
then I gently push power again. fine after that. weird, but it happens.
