Try to use a combination of FN and F4.
Customer Reply
Nothing. No response with power button
I left the computer unplugged and recharged it again no response at all when trying to turn it on.

Please, try to Press Ctrl + Win + Shift + B

No response. It is difficult to tell if the computer is switched on. Nothing on screen, no noise.
