Hi All, I ask for advice because I've tried all my best: The HP pavilion when power button pressed all lights (LEDs) go AND STAY on, but laptop does not boot, nothing comes on, how can i go ahead?

[.... My HP pavillion is in identical state... I wonder if it is faulty BIOS... Because all the lights go on and nothing comes on the screen... what shall i do ?

HP? NEVER AGAIN! The laptop is...
