ACER EXTENSA 5420-5687 screen does not light-up

ACER EXTENSA 5420-5687 screen does not light-up

My 3-year old laptop ACER EXTENSA 5420-5687 screen does not light-up and stays black when I start it. The start switch automatically turns off in 5 seconds. I have removed the battery and plugged it direct in the wall socket.  Please help.

Does it work without the battery plugged in?

It does NOT work without the battery, eventhough directly connected to the power socket.  Thank you.
