My XPS is dead. Tried everything. Dead. Help?

It might be the power fuse, or the hard disk, I am not sure, but my XPS recently became unresponsive after I closed the lid and let it sleep during my shift. When I reopened the lid and pressed the Turn on button, the laptop was gone. It evidently was put into some sort of deep sleep, and never was able to turn it back on again. I used 110V when I worked on it that time, it functioned perfectly, till it was put to sleep, and the world was never the same.

P.S. both 240V and 110V work perfectly with the device.
