S6 just packed up!

[riverrob1963]

So I left my Samsung s6 working perfectly normally by my bed. I return to find a black screen and the top left hand light glowing bright then dull blue intermittently. No other signs of life. It won't even let me reboot as pushing/holding down any buttons make no difference to anything. Please help!
