I have a Sony Vaio VPC-EC290X and It won't boot. When I connect the A/C charging cable (Sony cable that goes with the laptop) the battery charging light comes on. I press the power button and the laptop turns on but nothing appears on the screen. The cpu fan turns on and the cd drive responds when I press the button to open the door. I have noticed that the keyboard doesn't seem to be receiving power. It also sounds like something may have gotten into the fans as it makes a "crap in the fan" sound. After about 30 seconds the laptop turns off. To Recap:
Battery light comes on when A/C is plugged in.
When pressed, Power button lights up and laptop turns on but no video displays on the screen.
CPU Fan runs and after a few seconds the CPU fan rmp's increase
A few seconds later the laptop turns off.
CD drive responds to the eject button
Keyboard doesn't seem to be receiving power. (the caps, scroll and Num lights don't come on.)
I think its probably the Mother board being shot based on the symptoms I'm seeing but I want to make sure.
