Laptop wont turn on

Hello,
My toshiba sattellite pro doesnt want to turn on. i did the suggestion that tictaktoe released but with no success. i really need to fix it before my parents find out that it isnt working. back to the problem, my laptop was working fine, i was using it last night, but then this morning i tried to turn it on but didnt work..the led lights on the left bottom corner of the computer are on stating that power cord and battery is connected but it still wont turn on..any suggestions.please help,thnx !
