Dell xps1640 will not turn on


Oct 6, 2014
I have had the laptop from brand new had it 6 years it has had two new hard drives the last one two years ago it has also had new power supply and new battery about three years ago. the battery doesn't hold its charge that well any more so i have it plugged in most of the time was using it last week and put on the floor the power supply must have disconnected usually it would just go into hibernation mode but i came back to it and it was just bead i plugged the power back in and it will not boot up or do anything the processor light on the front doesn't even light up i can not hear the hard drive doing anything. i am going to take it to someone to look at it just wanted to know does it sound like the hard drive or something more? thank you
