if there no led on the mb/laptop with a know good ac power block and or a fully charged battery it could be the laptop power board or system board. if your using just the ac power check that the ac block is working..most times that the part that fails or the pin where the ac block plugs into the laptop breaks off or the pin shorts out the mb.

i guess the problem is not from the power block etc. cos when i open up the board, i read it with my digital meter it shows that 19vdc get to the power ic but still not working
