Hi,
We have had not one, but 2 Samsung laptops go wrong on us in the last few days:
R780 - Power light on but nothing happens when you press the on button.. Tried "cold" reset and still won't switch on.
NP550C-A08UK - No lights at all, tried cold reset and no response. These both worked a few days ago.
Thanks for any help in advance.

Which Windows versions (originally and now)? UEFI or CSM mode? Clean install or updates? Are you able to enter BIOS settings with F2? Are you able to boot an external source (USB stick or DVD)?
Check the following links. The first is the thread that has the most discussion about solving NVRAM corruption (a common cause of semi-bricking). The second has cases of harder bricking.
Unbrick when F-keys don't work at boot, cannot enter BIOS
