HDD P/N HD155UIVP4 > 1.5 TB

Everything was all the time ok ..until yesterday..i have used it normall it was not fallen or damaged on a other way.. i closed my laptop for dinner..after finnishing i want to use my laptop and my harddisk. But than i got some problems..  

The Harddisk seems to be dead   ..the laptop doesn't reconize it anymore. But i think there is more.
normally when you put the power adapter in your device ..it starts or the led light is flashing. You can hear that it starts up..now there happens nothing, No light no sound nothing..

How is that possible one hour before ,,everything was ok..after one hour,,nothing happenend
