Laptop not turning on

Hi. I am experiencing a problem with my Dell Inspiron N4010.  It is not turning on,  even the power button's light doesn't turn on when I press it, but the charging light on the laptop pad still turns on when I put it on charging. I have tried with the power flea method of removing battery and adapter and pressing the power button and re+connecting it to turn it on, but nothing works. There is no beeping or any sort of sound in the laptop either. Please tell me how to switch it on.

Thanks
