OK so you went dusting with the Power on.....Unplug PSU for and let it stand for about 45-60 seconds. Then plug it back on and turn it on...should work.

Plug in the charger to the wall socket without connecting to the laptop and check the LED on the charger if it is on.Now when it is on plug the charger to the laptop and check the LED if it is still on or went Off.If it went off there is a short on the 19v rail on motherboard.

If you did as I said and the LED on the power supply is on no short on main board.
Now if the laptop do not start try the easy methods.
Hard reset and take RAM out and clean with 99% spirit
